S.H. Fisher, Assistant Chief Operationg Manager of the LMSR address to the Institute of Transport. Notes submissions to the Transport Advisory Council from thge main line railway comapnies in the hope that some of the regulations placed upon railways would be reduced. Noted the quest for reduced transit times for both passengers and freight and for lighter vehicles, but observes that passenger trains were getting heavier due to quest for greater luxury. Pious hope that cross country transits would be eased (still further away than ever). Proposes use of bogie freaight vehicles carrying containers on routes such as London to Birmingham and Manchester to Glasgow. Notes limitation of short wheelbase four wheel freight wagons and suggests six-wheel

The Rock Island "Rockets". 3-4. illustration
Chicago, Rock Island & Pacific Railway: Electro-Motive Corporation locomotive with 1200hp Winton diesel two-stroke engine capable of 117 mile/h running with Budd welded steel articulated cars with sponge rubber seating.The cars were fitted with electric-pneumatic brakes, with a four-speed retardation control in the leading car, and automatic slack adjusters are provided to allow for wearing of the wheels and brake shoes. Flexible diaphragms fill the spaces between the car bodies, giving an unbroken surface from the nose of the locomotive to the tail of the observation car. The cars are finished in bright stainless steel outside, while the locomotive is treated in maroon and vermilion, with bands and lettering of stainless steel. The steel used in the construction of the cars varies in tensile strength from 100,000 to 150,000 lb. A four-car train contains 209 seats, including 32 dining seats, and weighs 150 tons without the locomotive unit. At present the·' 'Rockets" are in operation on five different routes, giving day services in an cases. Runs between Chicago and Peoria and Chicago and Des Moines are made by two four- car sets. On the three remaining services, Kansas City-Des Moines-Minneapolis, Kansas City-Dallas, and Fort Worth-Houston, four three-car units are employed. The Fort Worth-Houston service is worked jointly with the Chicago-Burlington and Quincy Railroad, the Rock Island "Rocket" working alternate runs with one of the Burlington "Zephyr" trains.

Until 1852 W. Bruton was the resident engineer and his responsibilities included locomotives. J.D. Sheriff officiated at the Carn Brea repair shops and Slater was succeeded by H. Appleby. When the South Devon Railway took over the locomotive stock became the responsibility of J. Wright. Three locomotives were taken over from the Hayle Railway: Cornubia, Carn Brea and Penzance. Coryndon was purchased from Chanter who had worked the line under contract. A 2-2-2 with smoke eliminator was constructed at Carn Brea from parts supplied by Stothert & Slaughter, brought by sea from Bristol to Hayle and thence conveyed by road. It was assembled by Joseph Ramsden under the supervision of Slater. In 1851 it was named Penzance, was changed to Hayle in 1858 and survived until 1860 and was not cut up until 1866

The history of the Highland Railway. H.A. Vallance. London: Arthur H. Stockwell, Limited.
Various factors have gone to make the old Highland Railway a favourite with those who love railways for their own sake. The beauty of the country it served had something to do with this, but perhaps even more compelling was the way this small company carried on traffic over long distances, in the face of Nature at her unkindest, and with a banking account that was never very fat. As might be expected, Vallance's book is a quite unofficial labour of love, and for it. he deserves congratulations, more, indeed, than those who have been responsible for the book's production. He has certainly made a very good job of it. There are seventeen chapters, covering the whole of the Highlandts history, beginning with Joseph Mitchell's earliest proposals for an Inverness to Perth direct railway, which was born in the Railway Mania of 1845. One may quarrel with a few of the author's non-railway references. It is hardly fair on General Wade, for instance, to wr i te that in building his famous roads he "only considered the military aspect of the undertaking" for Wade was a far-seeing and humane man who certainly did not have "pacification" as his sole object. On the opposite side, the memory of nineteenth century landowners in the Highlands, who were the Highland's principal sponsors, is somewhat buttered up, though it should scarcely be implied that the "improvements" (forced evictions) ceased with the coming of railway transport. Vallance's capacity as a railway historian is undoubted, and his account of the gradual formation of the ultimate H.R system, the quarrels with the Great North of Scotland, and especially of its unfulfilled aspirations, is most valuable. The Great Norrh adopted the role of an interfering rich uncle, though by that time was anything but rich. An excellent chapter, too, is devoted to the difficulties of single line working, and in this occurs the authentic story of the Englishman who took two days to travel from Inverness to Perth. Special chapters are also devoted to the train services, the H.R.'s unenviable role in the Great War, accidents and fighting the "Snow Fiend," as well as a complete chapter on the company's little-known steamships.
Though detailed accounts of performance, rebuilding, and working are necessarily precluded, the section devoted to Highland locomotives is comprehensive and reliable, the fortunes of even the obscurest Highland engines being faithfully followed. Very welcome, too, is the material, much of it hitherto unknown to the general reader, relating to the Carriage Department, and particularly to the early sleeping cars. But the reviewer is a little surprised at an historian of . Vallarices calibre referring to Alexander Allen, and to Sir John Rarnsbottom.
The illustrations are numerous and well chosen, but they suffer from poor printing. There are several most interesting maps, showing the system as it was, the system al Mitchell conceived it in 1845, and various suggested scheme in the remoter Highlands and in the Inner and Oute Hebrides. On the whole, Vallnce has given us a valuable book, which those who know the old Highland will undoubtedly welcome.

British light railways. R.W. Kidner. London: Oakwood Press. 28-9
In his preface to this work the author refers to travel on light railways as a mode "which was sometimes useful, too often merely comic, but nevertheless an important part of thl history of transport." Most of our readers will agree with this, and in view of the number of these concerns which have ceased to function during recent years, will be glad of a record of their scope and activities. The railways, over sixty in number, are dealt with in six groups, and for each there is a diagram of lines and stations, showing locomotive sheds and sidings with the distances of the principal stations, Dates of opening and closing, together with a list of locomotives and some details of coaches, track, signalling, livery and tickets, are also appended. The whole of the British Isles is covered by the work, which is illustrated by 91 excellent half tone blocks, these forming a useful record of the locomotives and scenery of the various lines. It is, however, much to be regretted that the small locomotive sketches, which number 204, have been so crudely drawn.

Old Euston. G. Royde Smith. London: Country Life Limited, for the London, Midland and Scottish Railway. 70 pp. plus 6 plates. 29
The book produced by that well-known authority on early railway history, the assistant secretary of the L.M.S.R., in accordance with the desires of the L.M.S.R. directors to have a brief retrospect coincident with the centenary celebrations of the London and Birmingham Railway, the first of England's main line routes, is not only accurate and balanced without being tedious or compendious, but is also delightful to read. The title is symbolic of the importance of Euston to the L. & B.R., and to the L.N.W.R. and L.M.S.R. in after years, and the contents are a resume of the human essentials of the first thirteen years of more than a century of activity rather than an account of the London terminus itself, the history of which can be summed up in one sentence of Mr. Royde Smith's: Nobody remembers the time when Euston Station was not being altered or added to in one way or another." First there are chapters on the origin of the London and Birmingham Railway itself, on the Euston extension line, the Hardwick arch and the Central Hall, and on the increase of traffic. Then comes an almost impartial but friendly chapter on Edward Bury and his locomotives, which everybody should welcome, for there has been a fashion to decry him. It was no joke being a responsible engineer on the L & B.R. in the early days, for the Quaker directors, Cropper and Rathbone, not only made Bury's life unpleasant, but, as Robert Stephenson recorded in a lenter to Michael Longridge dated 26 January 1835, they were in hue and cry after their civil engineer, too. Then again, it appears that some of the directors did not consider themselves there simply to direct, but to interfere in the management.
There must be some regret that Mr. Royde Smith has not spent just another dozen lines on the Harvey Combe, Stephenson's pa:tent engine of 1835. According to Warren, in A Century of Locomotive Building, it is this engine which is described in Marshall's Description of the Patent Locornotire Steam Engine of Robert Stephenson and Co., 1838, but Ahrons states that it is a somewhat later engine of the same type which is described in Tredgold's Steam Engine. The present records state that it was built for Belgium and sold to Cubitt, who was contractor for the London and Birmingham line, but Warren states simply (p. 320) that it was built [or Cubitt. The drawing in Mr. Royde Smith's book agrees with that given by Warren (which was taken from Marshalls work) except the positions of the dome and manhole.

Engineering workshop principles and practice. A.G, Robson. Manchester: Emmott & Co. Ltd., 29
The importance of this book to a student should be in almost direct relation to the time in his apprenticeship when he begins to study. If it should not come into his hands for six months Or a year after he has begun to serve his time, the undoubted value of the first half-dozen or so chapters will be lost upon him, for he will have already formed several bad habits which no amount of correct instruction will wholly break off. As the L.C.C. has adopted this work as a textbook, there is a chanoe here, at least, that the full value of the book will be extracted, In 32 chapters an amazing amount of general engineering and machine tool practice is covered, and covered well, for the text and illustrations give an apprentice just that what he needs to know about the tools and machines which he is to use and about others around him, although possibly it is asking a little too much of student-apprentices to expect them to appreciate the chapters on gauge-making, heat treat- ment of steel, and the manufacture and properties of metals. In its technical aspects the book is quite up-to-date, and is singularly free from those examples of Victorian engineering practice which are a characteristic of many works which originated in pre-war years.

Correspondence. 29-30

Edward Fletcher. J.W,A..
Re correspondence on Fletcher .boilers, and a cutting I have from The Engineer 30 June 1882, sheds some light on the weakness of Fletcher's boilers. Colonel Yolland, reporting on an accident to engine No. 204, class 398 (standard 0-6-0), which blew up at Thornaby on 26 December 1881, says "that the accident was probably caused by the crown of the firebox becoming overheated from want of water, and thus weakened, having been unable to resist the pressure caused by the sudden creation of steam upon water being admitted to the boiler. "
The boiler was only in use 21 months, and the copper firebox and stays were in good condition, and it was unknown whether the one water gauge was faulty or the driver had been careless, but he states that it is most desirable that duplicate gauges be fitted to all boilers. The main point of his findings, however, is that the difference of level between the top of the boiler and the crown of the firebox was only 13 in., which was small in the case of this engine, and would, of course, allow the firebox crown to become uncovered very quickly, without constant attention. He was not aware of the greatest difference in levels then existing, but some engineers kept down the firebox crown 20 in. below the top of the boiler, and 15 in.-18 in. was a common difference of level. The lead plug (which failed to give way) was found to have been covered over with a hard incrustation at the bottom of the lead. This had not been removed for four or five months, there being no regular time for renewal at that period. The above may throw some light on the Fletcher boiler weakness.
Incidentally, the five men killed in the explosion were buried in the North Cemetery, Darlington, and photographs of four of them are mounted in lead frames round the memorial erected to their memory.

Edward Fletcher. C. Hamilton Ellis.
Further to W.B. Thompson's comments on the liability of Fletcher's North Eastern locomotives to boiler explosion, the following extract from the official report on the Silksworth accident of January 1880 may be of interest: "From a careful examination of the surfaces of fracture there is but little doubt that the explosion commenced on the left hand side along .the junction of plates 1 and 4, where there is deep grooving in the lower plate, in some instances extending through almost its entire thickness in a line along the bottom of the overlapping portion of the upper plate. This grooving would have been hardly discoverable (even had it then existed) when the inside of the Iboiler was examined at the end of 1878, as it was to a certain extent covered by the overlapping edge of the upper plate. This grooving was no doubt more or less due to the proximity of the joint to the plate attached to the side of the firebox, which rests on another plate attached to the framing to permit of the expansion and contraction of the boiler. The bearing surface being considerable, a great deal of resistance is offered to free expansion and contraction, and much work, giving rise to grooving, consequently takes place in the joint in question."

Robert Sinclair. G.G. Woodcock.
Re article upon R. Sinclair in the Locomotive of November issue. Your contributor might have mentioned that Sinclair with Allan was one of the first to introduce long laps and valve travel as we know it to-day. Probably owing to the haphazard lubrication systems in use at the time, he as quickly dropped it. By the way, it is interesting to note that although Gooch had commenced construction of locomotives at Stratford, the first being his 2-2-2 tanks 1851-54, Sinclair never constructed any there except five small 2-4-0 side tanks for the Woolwich branch.

The Webb compounds. C. Williams. 30
Re the letters by W.B. Thompson and W.T.H. on page 402 of the December issue The first three Teutonic class compounds were built with experimental low pressure cylinders of different sizes, and just prior to the buiiding of the seven remaining engines of the class in 1890, Webb decided to adopt the 30 in. as standard. Consequently Teutonic retained the original l.p. diameter. whilst those of the Oceanic and Pacific were both modified to the new standard in ]890. Although not previously recorded, it may be of interest to note that a number of the Dreadnoughts were subsequently fitted with h.p. cylinders 15 in. in diameter, including No. 545 Tamerlane which also had the l.p. cylinder reduced to 28 in. in diameter. As regards the 0-8-0 three-cylinder compound No. 1880, I well remember seeing this engine in 1900 both before and after it was converted (the date 1903 for the latter is incorrect). Originally it had a large cylindrical (not Belpaire) firebox with a corresponding large boiler, and was so built, I believe, as an experiment. I regret that I am not able to furnish any details of the firebox in question.

Metropolitan Vickers Electrical Co., Ltd. 30
Railway Traction Work during 1938. Work on the electrification of the Central Railway of Brazil has continued satisfactorily throughout the year, the sections being open for traffic progressively as completed. The first order for 52 Metadyne Control Train Units from the London Passenger Transport Board had been followed by two further orders totalling a further 73 equipments. The order from the South African Railways for a further 42 electric locomotives received in 1937 has been completed. Twenty-seven of these locomotives were despatched before 31 October, and a further ten during November and December. The total number of locomotives ordered by the South African Railways was 162.
An important order had been received from the London and North Eastern Railway for the complete electrical equipments for 70 main line mixed traffic locomotives in connection with the electrification of the Manchesterv Sheffield-Wath lines. Work on these equipments was well advanced and deliveries would commence during 1939. The mechanical parts will be manufactured by the London and North Eastern Rly. at their Doncaster Works, where the Metropolitan- Vickers Company will erect the electrical equipment and complete the locomotives.
The locomotives will weigh about 84 tons each and run on 1,500 volts D C. They are equipped with 4-axle mounted motors having a total one-hour rating of 1,850 h.p. and designed to draw 250 ton passenger trains up a gradient of 1 in 125 at 53 m.p.h., 500 ton express goods trains up a similar gradient at 40 m.p.h., or 700 ton goods trains up a similar grade at 26 m.p.h. The maximum speed is to be 65 m.p.h. The locomotives are to be equipped for regenerative working, which will be a very valuable feature in handling the heavy freight rrains down the long grades in the Pennines. An additional 24 motor coach equipments for the suburban electrification near Sydney, Australia. had been ordered by the New South Wales Government Railways, The motors were being made by the Australian General Electric Company to Metropolitan-Vickers design, and parts of the control apparatus were being manufactured at Trafford Park.

The Butterley Company, Limited, 30
Butterley Iron Works, near Derby, have orders for the steelwork for a bridge carrying Wilford Road, Nottingharn, over the L.M.S.R., main line. The bridge has five spans and an angle of skew of approximately 45 deg. The old ironwork to be demolished weighs 350 tons, and the weight of the new steel structure will be 230 tons. The Butterley Company have also secured the contract for approximately 1,200 tons of steelwork in five bridges in connection with the widening and electrification of approximately two miles of track for the G.W.R. at Ruislip.

General Electric Co., Ltd. 30
The opening of an extensive addition tothe Southampton Works of Pirelli-General Cable Works, Ltd., an associate of the G.E.C., marks an important stage in the development of this Company's manufacturing resources. Originally, all types of Pirelli-General cables were made at Southampton, but in 1928 the increasing demand for power cable and super-tension ca-ble led to the erection of a new factory at Eastleigh, where paper insulated cables (including the super-tension oil-filled type) and telephone cables are produced. Additional space was thus made available at Southampton for the manufacture of rubber-insulated cable, flexible cords and covered wires for winding and instrument work, and in the last few years the factory has been successively enlarged, attaining a covered 'area of 350,000 sq. ft. at the end of last year. Recently, however, the still increasing demand made a new extension of 80,000 sq. ft. necessary, bringing the total area of factory under cover to about 425,000 sq. ft.

An appointment in the G.E.C. is that of R.C. Giggins to the administrative staff of its Government and Railways Department. The activities of this department have increased ver y considerably during the past few years, and present conditions have made it busier than ever before. Giggins has been with the G.E.C. for 24 years. Since 1929 he has been General Manager of the Company's organisation in Malaya, where he was one of the pioneers of-and later Chairman of-the British Malaya Broadcasting Corporation.

Report on Economic and Commercial Conditions in Portugal, by A. H. W. King, O.B.E. 30
Issued by His Majesty's Stationery Office references are made to the deterioration of the financial position of the Portuguese Railways due to road competition and increase in cost of coal and other materials. The average price paid for coal in 1936 was 18s. 11d. per ton, which rose to 27s. 3d. per ton in 1938. At the end of 1936, 2,768 km. of broad gauge and 723 km. of narrow gauge railway were being operated. The rolling stock consisted of 526 steam locomotives, 22 electric motors, 1,298 passenger carriages, and 9,601 wagons, of which 1,138 were privately owned.

Cast steel frames. 31.
The cast steel frame began to displace the forged bar frame in American locomotive practice about 1908. The reasons for this and previous changes may be briefly reviewed as illustrating the progress made in frame construction in that country.
The bar frame was originally introduced in the United States because no facilities existed for producing plates suitable for frames, whereas a smith of average skill was capable of forging a frame from bars. This frame never could lay claim to simplicity but was found in practice to possess certain advantages although expensive to make and repair.
The forged frame was displaced by the cast steel frame which in its original form consisted of cast steel side members, generally resembling the forged members they succeeded, independent cylinders, cross-ties, etc., being retained. At this juncture, 'it is of interest to note that where separate sides are still utilised the bar frame is sometimes produced by flame cutting from a solid steel slab; in this process the slab after straightening' is heated to between 400°F. and 600°F. and held at this temperature during the cutting process, being afterwards normalised. The present development of the cast steel frame has resulted from much research and may fairly be claimed to ha ve radically affected locomotive design, and as a corollary construction and maintenance. This type of frame is usually referred to as a "bed" and may vary between the compara- tively simple one-piece steel casting, comprising the sides and cross braces, as introduced in 1924, to the modern bed consisting of sides, cross braces, cylinders, back cylinder covers, inside steam pipes, smokebox saddle, sundry brackets, brake hangers, etc., constituting one of the most elabo- rate steel castings ever manufactured. At first sight it may appear that excessive weight must be associated with this form of construction, but this is not the case as the metal may be propor- tioned subject to the stresses involved-a procedure largely impracticable with the bar or plate frame. The obvious advantages are reduced maintenance and greater freedom in design.
There are many comparatively modern locomo- tives at work to-day which are in frequent need of frame repairs and alignment, cylinders tightening, etc.-troubles which cannot arise with the cast bed.
That the claim for reduced maintenance is amply substantiated would appear from the fact that railways in some countries are prepared to import these beds, although the cost is considerably increased by duties.
In addition to this type of construction being used on some of the largest steam locomotives, e.g., the Baltimore and Ohio 4-4-4-4 engines, (the bed of which has four integral cylinders), and the Southern Pacific 4-8-8-2 articulated locomotives (having a bed for each unit), the one-piece cast bed is also utilised for Electric and Diesel locomotives. Representative of the former are those incorporated in the Pennsylvania Class GG-1 electric passenger locomotives, while some of the latter have the fuel-oil and water tanks cast integral. The type of construction under review is definitely established and one firm alone has sup- plied upwards of 1,650 cast beds to some 40 rail- ways operating on the American and Australian Continents; further, the use of these is by no means confined to new construction as they have been applied to literally hundreds of rebuilt engmes. .
So far locomotive builders in this Country, while no doubt generally interested in these frames, have refrained from incorporating them or producing them, but the time has come when the production facilities must be reviewed.
Fashions in locomotive practice may not change frequently, but when change is decided upon it is usually and necessarily sudden. As an example we may cite the etherlands Railways; for many years Holland was looked upon as a stronghold of British practice and plate frames were as a consequence used, but when new locomotives were supplied in 1929 bar frames made their appearance. It is probable that an enquiry from an overseas market may before long contain a stipulation that a cast bed must be incorporated.
While locomotive builders need not necessarily produce such units themselves—and in America many are produced and machined by steel founders and supplied to builders-it would, we think, be opportune to ascertain, and if necessary assure, that facilities are available here for the production of such castings. It would also be advantageous to look over machine-shop equipment, as although the machining required is far less than on a frame assembled from components, the setting-up and machining of such a large casting obviously presents problems to shops hitherto dealing only with the smaller components. of plate or bar frames.

South African Railways, new Beyer-Garratt locomotives. 32-3. illustration.
Part of an extensive replacement programme, sixteen Beyer-Garratt locomotives with the 4-8-2 + 2-8-4 wheel arrangement had been supplied by Beyer, Peacock and Co. Ltd. of Manchester. Among many features was the provision of an auxiliary water tank (not shown in illustration). This was necessary in order to keep the max. axle weight down to 15 tons; even this is a higher loading than normally permissible and was conceded conditionally on the weight usually placed on the bogies being reduced, together with a restriction in reciprocating balance. These engines were believed to be the most powerful ever placed on 60 lb. rails and were intended to work on the Johannesburg-Zeerust-Mafeking line; with long grades as steep as 1 in 40 in addition to curves as sharp as 477 ft. radius. The comparatively large wheel diameter of 4 ft. 6 in. was decided upon with a view to reducing maintenance costs and to permit of the use of these locomotives on passenger trains. For an engine of 3 ft. 6 in. gauge the boiler was of exceptional size, but despite this the centre is only 8 ft. 6 in. above rail level. Although a new type, these engines contain many details and parts interchangeable with those of other recent classes. A smart appearance has resulted from leaving the planished steel covering of the boiler unpainted and the use of stainless steel crinoline bands, hand rails and cylinder covers. On test these engines have handled trains of 750 tons, and it is anticipated that their use will increase the capacity of the line by approximately 50 per cent.

Departure of the "Coronation Scot" to America. 33
The M.S. Belpamela left Southampton Docks on Thursday, 26 Jan.. Two special trains, one composed of the engine and the 'Other of the coaches, made a midnighrt: journey from Willesden Junction direct to Southampton Docks, arriving there in the early hours of January 19. The engine did not travel under her own steam, but was hauled dead with connecting-rods and other gear packed up securely for the 2,000 miles sea journey. The coaches, covered with a coating of wax to protect them from exposure, and a1l movable fitments securely lashed, formed a separate train. The engine and tender were lifted by the ship's derricks into .the hold, and the coaches, lashed and screw-coupled, were carried on deck. The Belpamela was expected to reach Baltimore, her port of entry into the United States, on or about 14 Feb. Immediately on arrival the train will be assembled at the Baltimore shops of the Baltimore and Ohio Railroad and, after a trial run, will start on her 3,121 miles American tour prior to exhibition at the World's Fair, New York.

Correction.- 33
It was stated in our Irish Notes last month that the proposed capital of the new Northern Ireland Transport Merger was the sum of four million pounds. This figure, however, only refers to the existing capital liabilities of the Northern Ireland Road Transport Board, and the capital of the new body will be considerably greater.

"The Coronation Scot" [for the] New York World's Fair, 1939. 35-9. 7 illustrations, plan.
L.M.S. train destined for exhibition at the New York World's Fair was shipped to Baltimore from Southampton on 26 January 1939. Prior to going to the World's Fair the complete train with locomotive No. 6220 Coronation would visit several American cities. No. 6220 had been specially fitted with a bell and searchlight, shown in the photograph.
The train is a portion of that under construction at the Derby Works of the L.M.S. Railway for service in Great Britain, and consists of three articulated twin sets and two loose cars, made up as follows:-
Corridor 1st Brake, Corridor 1st Class: Articulated Twin Set (16 and 24 seats): 40 seats. Corridor 1st Lounge, 1st Class Dining Car, Articulated Twin Set (28 and 44 seats): 72 seats.
Kitchen Car, 3rd Class Dining Car, Articulated Twin Set: 44 seats.
1st Class Sleeping Car, Separate Car: 12 berths. Club Saloon, Separate Car: 17 seats.
Totals: 173 seats and 12 berths.
The exterior painting is in the standard L.M.S. colours, with four gold bands running the full length of the train, continuing round the shaped ends of the brake compartments at each end, and finishing in a "V" shaped point in the centre. These bands also appear on the engine.
Exterior projections have been reduced to a minimum, the roof, sides 2nd ends being covered with 16 S.W.G. steel panels finishing flush with the windows, and between the bogies is a sheet metal valance to within 12 in. of the rail level.
To preserve continuity of line, the spaces between the adjoining ends of each pair of vehicles are closed with rubber sheeting, the exterior thus presents a smooth uniform appearance over the whole length of the train.
The body side doors are fitted with "Beclawat" spring balanced frameless drop lights.
Special attention has been paid to sound insulation. The corrugated steel floor sheets are welded to the steel underframes, and the underside sprayed with " Limpet" asbestos 3/8 in. thick, the flooring consists of cork 1 5/16 in. thick on which is laid felt, linoleum, and carpet.
The inside of the roof, bodyside and end panels and framework are sprayed with "Limpet" asbestos, whilst the walls and partitions of the dining cars and lounge car are lined with leather on a felt foundation.
The body sides are also fitted with twin glass windows having an air space of ¼in. between in order to insulate against heat and sound.
The design of the body and underframe is arranged so that the solebars and cant rails are combined as one unit and the trussed longitudinal members another.
Solebars and cant rails are of Colville's high tensile steel channel section and welded to these are steel sockets to receive the teak body pillars, which are bolted in position to the sockets. Between the quarter light pillars, the body frame is reinforced by steel diaphragms, which have steel angles, spot welded along each vertical edge. These diaphragms are welded to the solebar, cant rail and sockets, and attached to the timber pillars by bolts passing through the angles on the diaphragms.
The steel body panels (16 S. W. G .) are welded throughout in one unit extending between each pair of bodyside doors and secured in position by screwing to the timber framing and welding to the cant rail at the top. The galvanised steel roof panels are welded in position to the roof members which are of light construction, the latter being secured to the cant rail by welding.
The bodyside framework is ventilated throughout by introducing an air stream through grooves provided at regular intervals of 6 in. between the bottom edge of the bodyside steel panels and the timber securing fillets attached to the solebars. The steel roof panels are also arranged with the bottom edge clear of the bodyside panels, thus providing an air space along the whole length of the car.
Complete circulation of air is effected by providing ventilation holes in suitable positions in the bodyside framing, cant rails and roof members.
Exterior ventilators are fitted, evenly spaced, along the centre of the roof.
All underframe members, with the exception of the solebars, are of mild steel and welded throughout. At one end of each articulated underframe is fitted the standard draw and buffing gear, and at the other the Gresley type of articulation coupling.
The bogies are constructed of mild steel, welded throughout and have laminated springs, following the design of those fitted on existing L.M.S. articulated stock.
The interior decoration of the corridor compartments is carried out on modern lines, a flush finish being obtained by the use of veneered panels. A variety of selected Empire timbers are used, each compartment being finished differently.
The corners of each compartment above the seats are rounded, with a cove veneered to match the panels, thus giving an unbroken line to the finish.
The seats are deep sprung with loose cushions. Dunlopillo armrests and head rests are upholstered in uncut moquette, self- coloured except for vertical lines in the blending colours. Three colour schemes are introduced, blue grey, brown and plum, the curtains and carpets toning with each of the schemes. A telephone is fitted below each window for communication with the attendant in the kitchen car, and each passenger is provided with an electric cigar lighter.
The corridors are flush finished in figured teak, with sycamore inlaid banding, and walnut plinth.
The lavatory finish is in blue rexine, with rounded corners and ivory ceiling, porcelain pedestal wash basin, lavatory hopper and toilet shelf are coloured to tone with the walls. Blue and white Terazzo mosaic is used for the floor which is fitted with a deep cove to facilitate cleaning. Hot and cold water is provided and a "Dixie" cup drinking machine with water filter is fitted. The windows in these compartments are circular, the top half being hinged for use as a ventilator. The usual outside semaphores are not fitted in connection with the passenger communication apparatus, but an indicator is placed in the vestibules above the outside doors, which in its normal running position, shows a white disc behind a glass panel. When the apparatus has been operated a red disc appears, and it can be returned to normal by the guard with a few turns of a key, bringing the white disc in view again and at the same time allowing the valve to be reseated in the passenger communication valve box, situated on the end of the car. The latter is connected to the vacuum brake train pipe as is the standard practice. The interior of the Club saloon is finished in brown oak, with ivory enamelled ceiling. The body side and partition panels are relieved by a triple twist rope moulding. Chairs and settees upholstered in coral leather are arranged in groups as will be noted by the illustrations. The floor is covered with a nigger brown fitted carpet, divided into squares by red lines. The curtains are in colours to tone with the furnishings.
An electric glow fire is also fitted in the centre of the cross partition at the opposite end of the saloon to the brake compartment, and with a settee and easy chairs suitably arranged gives a fireside effect to this end of the car.
In the interior decoration of the 1st and 3rd class dining saloons, a novel effect has been obtained by lining the walls and partitions with leather on a felt foundation. The seats are also upholstered in leather with loose cushions, the double seats being designed to give the passengers individual seating, the seat ends are also covered with leather and supported on metal legs. All fittings are finished in silver plated satin, and the metal cornice mould has a leather insert coloured to tone with the walls of the saloon. The colour scheme for the 1st class dining saloon is grey for the walls and seat ends with dull pink seats and back, the sliding doors being faced with Bakelite to match the walls. The third class dining saloon has green walls and seat ends with brown for the seats and backs, and doors finished with Bakelite panels.
The ceilings in both saloons are panelled in 3-ply with ivory enamelled finish. The fitted carpets and curtains are in colours to tone with the respective colour schemes. The seats are arranged two on one side of the gangway, and one on the other side, except at the doorways, where double seats have been eliminated in favour of a group of single seats. This arrangement provides ample space for the movement of passengers and attendants, and avoids disturbing diners in the vicinity of the doorways.
The interior decoration and arrangement of the cocktail lounge is distinctive, and introduces some new features. The walls do not follow the contour of the body side but are built out from the cant rail, providing a flat vertical side with wide window sills. The ventilating and heating duct is housed behind the boclyside panels, and an alcove electric light fitted between each pair of windows extending the full depth of the latter. The curtains are so arranged as to hang back clear of the window span when not in use, giving the passengers full advantage of the large observation windows.
The walls and partitions are covered with blue leather as also is a portion of the ceiling across the car adjacent to the partitions, leaving a ceiling panel of ivory finish, down the centre of which runs a specially designed electric light fitting. The doors and sills are finished in blue. The walls and partitions are panelled out with chromium plated mouldings, and as in the case of the dining cars, the leather is mounted on felt. The colour scheme of the compartment is red, white and blue, the tables and fixed swivel chairs being upholstered in blue. The blue carpet is divided into squares by red lines; red and white are also introduced in the design of the curtains and table tops.
The cocktail bar recess has a flat ceiling with a dome. The walls adjoining the bar are covered with cream Wareite with interesting mural designs. The counter top is veneered with red Bakelite, and stainless steel edgings. The front of the bar is padded with Dunlopillo rubber, covered with blue leather and divided horizontally into three sections, with white leather covered beads, and :finished with a stainless steel skirting. Three revolving stools uphol- stered in red leather and having chromium plated tubular standards are spaced round the bar. The back of the bar is fitted out for service. A sink is provided with hot and cold water, the former being supplied from a boiler situated in the under frame below.
The sleeping car was built in 1936 and has been withdrawn from traffic to accompany the train to America. It has a welded steel underframe and six-wheeled bogies, of the standardL.M.S. design for this class of stock. The body framing consists of timber pillars secured by steel sockets which are welded to the underframe and steel angle cantrail. The body sides, ends, and roof, are covered with 16 S.W.G. steel panels, the latter being welded to steel angle roofsticks.
Twelve berths, lavatory and attendants' compartment are provided, and from the latter, light refreshments and hot beverages can be served. The corridor is finished in walnut and sycamore. The walls of the berths are covered with blue green shaded material, and the bedspreads and carpets are to tone. The wash basin is pale yellow porcelain, with hot and cold water taps.
Ventilation and heating are effected by a Thermotank equipment. The ventilating unit is housed above the vestibule ceiling and, through separate ducts supplies heated air and air at atmos- pheric temperature to a punkah louvre in each sleeping berth. The air is cleaned by filters of the viscous type. Ceiling, mirror and bed lights are provided, the latter having dimming facilities.
The kitchen car has new features including a solid fuel burning cooking range. Smokeless fuel is fed by gravity on to a special form of grate which combines the functions of preheating and the first stage of combustion. The first part of the grate is inclined, and this forms the preheating zone; there, the fuel is brought to ignition temperature before any air is admitted, by radiation from the refractory walls of the firepot. The combustion zone is the horizontal part of the grate, which is fitted with an ash ejector. The fuel-bed works as a semi-producer, and it is thick enough to ensure that the gases leaving the fire-pot contain a high proportion of combustibles. Secondary combustion is obtained by preheated air introduced into the flue of the oven. The hot gases are burnt by this secondary air with a re- versed flame, and so they are raised to a temperature that permits very high rates of heat transfer both to the hotplate and to the griller. The latter is a patented device developed on behalf of the British Coal Utilisation Research Association by Professor Rosin, which grills very efficiently without an exposed fire. The essential feature of the Rosin grill is a refractory brick dividing the gas stream and transmitting a controlled portion of the heat to the grilling surface by re-radiation. The cooker proper is of normal type, and is designed to give all the facilities of the present gas cookers, but with an increased hot plate capacity. Hot water for washing up, and boiling water for making tea and coffee are provided by a special steam boiler, using forced steam circulation for operating a compound calorifier for hot and boiling water supply respectively. This boiler is also fed by gravity.

Transport Tribunal for Eire.
Sean Lemass, Minister for Industry and Commerce, has appointed a tribunal to examine transport problems in Eire. He stated that he had been informed by both the Great Southern and Great Northern railway companies that in respect of each an acute position of financial stringency had arisen, and that Government assistance was urgently needed to carry on. The tribunal is under the chairmanship of J. Ingram, and is to issue a report in February. In this connection it may be stated that far-reaching proposals for closing down unremunerative lines have been formulated. All branch lines and several secondary main lines may possibly disappear, and their place will be taken by an extensive system of road services radiating from the principal stations on the main line railways.

A centenary of Austrian locomotive practice. F. Gaiser. 62
In the articles, "A Century of Austrian Locomotive Practice" (May, July, Sept. and October of Locomotive Mag.), the Hall system is frequently alluded to. As this system is somewhat intricate, it is excusable if inaccuracies 'have crept in. As to the first of Hall's innovations, Derens correctly states on page 368 of the November issue that they were started in Munich and not in Austria. He also describes the "Lagerhalskurbel" (journal or bearing crank) in such a lucid manner that nothing can be added. There are, however, some other points which need to be corrected. Joseph Hall left England, where he is said to have collaborated with Robert Stephenson, for Bavaria in 1840, and became locomotive engineer of the Muenchen and Augsburg Rail-way. He soon won the full confidence of Joseph Anton von Maffei who was general manager of the M. & A. Rly., and when this gentleman decided to build locomotives in his own works at Hirschau near Munich, he appointed Hall as works manager, Maffei himself being merely a financier not an engineer. During his stay with Maffei, Hall brought out his two patents which so greatly influenced the locomotive building in Southern Germany, especially in Bavaria, and later on in Austria, viz. :— (a) The patent of 1853, concerning his eccentric crank, and (b) That of 1856, concerning his journal crank, both referring to outside framed outside cylindered locomotives only, the object being to put the eccentric outside the frames without resorting to Crampton's return crank which would have, made the engine too broad. For this purpose the two eccentrics, wrought in one piece, were forged on to the inside of the crank web, the connecting rod in this case being always nearer to the engine centre than the coupling rods, thus holding the cylinder distances at a tolerable distance. With this device, the eccentrics could not be altered in their relative position to each other, nor in that to the axle, and this might theoretically seem a defect; nevertheless, the engines worked excellently in practice and were great favourites with the men. The eccentric cranks were only practicable on single and hind coupled engines, therefore when the Bavarian State Railways ordered two experimental engines in 1856, one a 0-4-0 and the other a 0-6-0 engine, Hall had to take out a fresh patent for his journal crank. The invention was not entirely new because one had been shown at the Paris Exhibition of 1855 on an engine for the Paris-Sceaux Railway. In most of the 0-6-0 coupled engines of the second Hall system the motion was entirely inside the frames ; there were, however, a certain number of locomotives, especially in Austria and Russia, where loading gauges are more liberal, which had return cranks for the eccentrics as well as Hall's journal cranks. Such an engine is shown on p. 285 (Brenner Rly., drawing and photo.), but the return crank as such has nothiing to do with Hall's patents. It is and remains Crampton's invention and has never been claimed by Hall. When in 1858 Hall went to Austria as works manager of W. Guenher's locomotive works at Wiener-Neustadt, there immediatly followed an increased demand for locomotives construted on his patents for Austria, Hungary, Russia and even ermany. Hall left Wiener-Neustadt in 1860 to superintend the rail-rolling mills of the Southern Ry. at Graz, yet the demand for his locomotive system remained unabated for several decades. The number of 257 engines with Hall's journal cranks as given on page 368 of the November issue refers only to 2-4-0 locomotives built for Austrian railways. The number of 0-6-0 engines with such cranks must have reached two thousand at least, considering that the Hungarian State Railways alone had about seven hundred besides, there were many in Austria, Bavaria, and on certain Prussian and Russian railways.
An interesting variety had grown up in Prussia, a 2-4-0 passenger engine with Hall journal cranks for the driving axle only, 199 in all (see Helmholtz and Staby p. 182/3). From 1867 onwards some of the Austrian railways with-drew from the Hall system without abandoning the outside frame, and built their engines with ordinary cranks. The two upper pictures on p. 360 of the November issue show engines of this latter description. If they had had Hall cranks described in the patent of 1856, there would be no place for fastening an eccentric (for working a feed pump) between the frame and the crank. In these cases the cylinder dis-tance was excessive ; but this seemed preferable to the fre-quent breakages of the Hall cranks. Engines with Hall's eccentric cranks were scarcely less numerous than those with journal cranks, but at the time of the Vienna Exposition (1873) the name of the inventor com-pletely vanished so that Hall addressed a' letter to the editor of "Engineering" to assert his authorship ("Engineering," 1873, p. 349). In former volumes of the "Locomotive" two engines with eccentric cranks, both built by Maffei, were illustrated, the one in Vol. VIII (1903, I p. 375) and the other in Vol. IX (1903, II) p. 102.

Design and maintenance. 63
Despite the constant small advances which are being made in the thermal efficiency of the steam locomotive, such as lower coal consumption and lower water and steam rates, there is comparatively little further to go before the limit is reached if present principles are retained. It is true that considerable improvement could be made in the performance of the generality of loco- motives in the matter of live and exhaust steam flow and in valve motion design, but the latest type~ of well-designed main line engines take full advantage of modern knowledge and research. On the other hand, of the millions of pounds which are spent each year in repairing. steam locomotives and keeping them m runmng trim, an appreciable proportion could be saved by closer attention to the detail design, and, generally speaking, progress in this phase of locomotive life has not kept pace with developments in cylinder, valve motion and boiler design as affected by considerations of thermodynamics. But time is money, and quite apart from any improvements in the actual design of details which will result in longer life, the facility with which adjustments and repairs can be carried out may have a much bigger effect on the total operating cost than, say, even a ten per cent. sav- ing in the fuel consumption.
It is for this reason, above all others, that roller bearings have become popular for axleboxes. The. fact that they produce less frictional losses is of no real consequence except, perhaps, for certain electrified urban and suburban railways, but it is a very real gain to have a box running for a couple of months without inspection, and runnmg possibly four or five times that period without reguiring anything more than topping up with oil or grease, and for this saving the extra first cost and dead weight of the box is a small price to pay. The ordinary outside axlebox is by no means always easy to deal with, particularly m the quick withdrawal of the brasses and keys. These details, and the axle collars and shoulders, should be so proportioned that the lift before the whole box can be pulled off is a minimum. The usual leather or wooden guard at the back is generally anything but dust-proof, and many troubles can be traced to this cause.
As a rule, large-wheeled engines are more economical to maintain than are smaller-wheeled varieties of the same general type, partly owing to the fewer power impulses and revolutions for a given mileage, but also because of the generally greater accessibility of the motion and running gear. The usual freight engine with small and closely-pitched wheels, often almost solid with balance weights and crank arms, is deficient im respect to the ready accessibility of details such, as spring and brake nggmg and axlebox tops. For such engines a reduction in the balanced proportion of reciprocating weights brings a double advantage, for not only is the riding easier, and the hammer-blow lightened (almost invariably there is a greater percentage balanced than is necessary), but the sizes of the weights in the wheels are reduced, and it is then easier to get between the spokes when making repairs to the brake, spring and other rigging. Double-bolt strap-type big-ends are nothing short of an unmitigated nuisance, and there is no reason for their perpetuation. Great improvement can be recorded over the last few years by the adoption of a simple end in which the keep is in one forging with the bolts, and the rod foot fits over these bolts. This pattern can be used with or without adjustment. The non-adjustable big-end is of itself a great contribution to simplicity, but the amount of big-end knock which is heard these days is an indication of how carefully the maintenance work should be performed.
Many improvements on the lines mentioned above are to be found in the leading express types, but less attention has been paid to freight, shunting, and industrial designs, in which, for example, strap ends are still common for new engines, even in conjunction with extremely short rods. The majority of these locomotives have boilers pitched at a lower height than is necessitated by the loading gauge; not only is the firebox volume thereby diminished, but with inside-cylinder engines the boiler is right down on the motion, and it becomes a tedious matter to replace such details as the valve spindle and crosshead cotters. It is usually easy enough to knock these out from below, but it is almost impossible to get a swing of the hammer when replacing them, and if they are inserted at a fiat angle the shape of the frames and the location of the motion plate, guides, and rods prevents any advantage being gained. The cylinders of such engines usually being jammed close up behind the drawbar spring, it is an awkward job renewing piston rings, particularly when the engine is hot. The quality of the maintenance available for shunting and industrial engines is not always of the best, and for such instances outside-cylinder engines have a distinct advantage. Lettere from J.G.B. Sams on p. 126 on roller bearings.

Institution of Locomotive Engineers. Problems connected with locomotive design. 64.
W.A. Stanier's Presidential Address given on 22 February 1939 dealt with some of the problems in locomotive design still to be solved and methods adopted on the L.M.S. Rly. to meet them. A few extracts from the address follow.
The increased size and weight and higher speeds are bringing into prominence all over the world the necessity of studying the locomotive more closely as a vehicle on the track. The inter-dependence of the engine and the track it runs on has long been recognised, but we in this country have been in a fortunate position for many years i.n that our track has generally been able to withstand, by a generous margin, the loads and forces which our locomotives have brought to bear upon it.
It is becoming realised that the lateral forces exerted by the engine on the track are of hardly less importance than the vertical loads, and the question of the guiding of an engine and the flange forces exerted is coming into prominence. Experiments have drawn attention to the fact that it is the leading coupled wheels at which the highest flange forces are attained. It is easy to visualise this in an engine without guiding wheels, and, where guiding wheels are fitted in the form of a bogie or pony truck, some degree of control has to be exerted. The object is not only to relieve some of the coupled wheel flange forces when the engine is rounding a curve, out also, by restraining the extremities of the engine, to avoid oscillation and resulting flange forces on the straight. The problem consists of so choos- ing the arrangement and value of the guiding elements that the flange forces of even a heavy loco- motive at high speed remain well within what the track will stand, either on curves or on the stra-ight. Bogies and trucks exert their centring effect by various arrangements depending on gravity in the case of swing links and inclined planes, or on centring force directly applied by springs. While at first sight it would appear an easy matter to ensure that the bearings on which an engine runs should remain trouble free, hot boxes have at all times presented a problem, and they still exist. The goal to be sought is their total elimination, and that good progress is being made can be instanced by the fact that 1,096 engines of six different types, all having the same general design of axle box, although varying in actual dimensions, ran through 1938 with a total of 89 casualties due to coupled wheel hot boxes. This represents the probability of a hot coupled box failure on any given one of these engines was once in twelve years.
With higher valve velocities which have become common due to longer valve travels and higher running speeds, it is realised that even a small degree of wear in motion pins and bushes may seriously affect the efficiency of the steam distribution. To keep this wear at negligible proportions, and, at the same time, to increase avail- ability by reducing lubrication needs to a minimum, needle roller bearings have been introduced on many recent engines. Of particular interest is the application to the rocking shaft of a four-cylinder engine. With the consequent elimination of wear at the fulcrum point the main objection to driving an inside valve gear from an outside valve gear on such an engine falls to the ground, and a considerable simplification has thus been possible.
In concluding his address, Mr. Stanier said: "I have only dealt with some of the many problems which confront us. Seeking locomotive improvement is like seeking after gold. Old-timers in the gold country used to obtain the precious metal by the most simple and primitive methods. They used even to find gold nuggets lying ready to hand in the river-beds. Now, in those same goldfields, it is necessary to instal the most expensive machinery and draw upon all the resources of modern science to win the gold from the mother rock. In locomotive design also it has been possible to win large savings in the past by relatively simple means, but each succeeding economy is subject to a law of diminishing returns, and there is visible all over the world a tendency to realise that in order to establish further gains more elaborate testing apparatus must be set up and the resources of science drawn upon.
In the matters which we have been discussing, therefore, it is necessary to obtain means of measurement which must not only be exact but must also be capable of isolating and evaluating each individual factor in a complex problem whilst the others remain constant. In the difficult problem of the locomotive as a vehicle on the rail it has been indicated how the different forces must be measured and recorded, and for this purpose electrical apparatus is required which is neither simple nor cheap."

Continued from page 20. The accident at Radstock on 7 August 1876 involved two 0-6-0STs meeting head on: 15 passengers were killed and Nos. 6 and 7 were involved. Numbers 6-9 were supplied by Fox, Walker & Co. in 1876 and were WN 320-3. These were almost identical to the original six coupled saddle tanks. Fig. 21 is a drawing of the new series. No. 2 received a new boiler in 1885; No. 3 in 1893; Nos. 4, 5 and 7 in 1890, No. 6 in 1894 and No. 9 in 1899. The cylinder size was reduced from 17½ to 17 inch diameter at the same time and the cabs were modified. No. 8 was converted to a side tank and No, 1 was converted to an 0-6-0 tender locomotive in 1888, but reconverted to a saddle tank in 1908. Seven received Deeley boilers jn 1906-11. They all survived for about fifty years, carrying out banking duties from Batth and Radstock. Some lasted long enough to receive LMS numbers. Fig. 26 shows No. 1500.

Steady progrcss had been made with the construction of the new P class locomotives, four of which were in service. They are named after rivers and the four running were the Ashburton, Avon, Blaclnvood, and Fitzroy (last illustrated).
A larger and more powerful type was under consideration and drnwings had been prcparcd of a 4-8-2l engine Many of the older types needed replacement and a building programme for new cngines would be commenced in the near future. The total number of engines in service at the end of 1935 was 422, including two petrol works shunting locomorivcs. The six Diesel eleotric railcars had been in service for nearly a year and the results have proved very satisfactory. Sunday services from thc hills to the coast and trips in the reverse diretion during the winter were regular features of the working for these cars, whilst private parties use them for special journevs.
Thc regular services were between Perth and Merredin (main line), Perth-Katanning, Bunberry-Northcliffe, Burtberry-Busselton , Bunberry-Bonnybrook, Gernldton-Muslewa, Gernldton-Yuna. The cars bear names of Governors of the State, viz., Stirling (illustrated), Hutt, Weld, Hampton, Lawley, and Bedford. The time table for the new services showed an average saving over previous running schedules of nearly 40 per cent.

London, Midland & Scottish Rly. 75
New 2-S-0 standard freight engines (Class 8) completed and turned out from Crewe were Nos. 8I04-10. In our February issue it was stated that Nos. 8096-8100 of this series had been allocated to the Midland Division. These five engines, together with the remainder of the series, Nos. 8101-8110, were all in service on the Western Division and stationed principally at Willesden. A further series of the same type (1939 programme) were already completed, .but not yet in traffic. Work was also well advanced on a new series of 4-6-2 Princess Coronation class locomotives, all of which would be streamlined, similar to Nos. 6220-9. Recent withdrawals included 4-4-0 George the Fifth class, No. 25357 Bassethound, and another of the few remaining 0-6-0 special tank shunters, No. 27358. At Derby a series of 0-6-0 freight engines (Class 4) was under construction, numbered from 4577 upwards. Thirty in all of this type were to be built which would be followed by a series of twenty 2-6-4 two-cylinder passenger tanks. Class 1 0-6-0 shunting tank No. 1851 had been withdrnwn.

No. 6 was bought secondhand from Stafford Colliery. It had been built by the Hunslet Engine Co. in 1889. It was an inside-cylinder (13½ x 18 in.) saddle tank and was scrapped in 1924. The seventh locomotive was also secondhand and was a Manning Wardle contractor's locomotive built in 1897/8. It received a new boiler in 1903 pressed to 140 psi and a futher one (180 psi) in 1923. It was withdrawn in 1931 and scrapped in jn1935. The eighth locomotive was built by Hudswell Clark in 1900 and is shown in Fig. 3. It received a new 180 psi boiler in 1936 when the total heating surface was increased from 569ft2 to 587ft2. The grate area was 10.6ft2. The locomotive was intended as additional provision for the "mines" but was later diverted to a variety of duties within the Frodingham Works. Subsequently, it was used at Appleby for the haulage of heavy hot-iron ladles ("jumbos") over a lengthy route between the ironworks and steelworks furnaces. For this purpose it was found insufficiently powerful and in need of fairly frequent assistance. The increase in working pressure raised the nominal tractive effort very considerably. The accompanying increase in heating surface proved insufficient to maintain the effort continuously, but the locomotive was well suited to mill or other shunting on level track.

Seven more 4-6-0 express engines had been completed at Swindon, No. 7812 Erlestoke Manor, No. 7813 Freshford Manor, No. 7814 Fringford Manor, No. 7815 Fritwell Manor, No. 7816 Frilsham Manor, No. 7817 Garsington Manor. and No. 7818 Granville Manor. Another 2-8-0, No. 3803, a 2-6-2T No. 8104 and five 0-6-0 tanks, Nos. 3602 to 3606, had been put into service. The following have been withdrawn: No. 2990 Waverley and No. 4070 Neath Abbey (4-6-0), No. 3253 Boscawen, No. 3290 Severn, No. 3306 Armorel, No. 3409 Queensland, and No. 3423 (4-4-0). Nos. 4339, 4367, 4388 and 8308 (2-6-0), also No. 254 (0-6-2T).

Carriage interior painting: cellulose lacquers. 77
It is only of recent years that cellulose lacquers have been considered for finishing work on carriage interiors, and their application has largely taken the place of French polishing. The special properties of clear cellulose lacquers have a definite appeal particularly in accelerating the finishing schedules for the interior decoration of certain compartments. These properties are mainly the speed of application, the rapid drying with a non-tacky film, and freedom from marks. Durability of the clear cellulose film was established under direct exposure tests and the resistance to moisture, checking, etc., were far in advance of the old polish finish. One of the larger railways carried out extensive experiments a few years ago and found that the finishing of interior panelling with clear cellulose lacquer was more economical than polishing owing to the speed of application and hardening, and the largely decreased labour costs.

Northern Counties Committee: Nos. 50 Jubilee and Parkmount were built by Beyer, Peacock & Co. in 1895 as two-cylinder compound 2-4-0 with 7ft coupled wheels, the largest diameter on any Irish railway. In 1897 both were modified as 4-4-0s. They were classified as Class D. In 1926 No. 50 was rebuilt with two 19 x 24in cylinders, larger boiler and classified D1.
Belfast & County Down Railway. No. 6, then only used a a spare was a Beyer, Peacock & Co. 2-4-0 built in 1894: threee almost similar, but two-cyliner compounds ahd been scapped in 1920. Three 2-4-2Ts built by Beyer, Peacock & Co. in 1896/7 were still running with the numbers 5, 7 and 27; No. 7 was illustrated in Vol. 9, page 188. No. 9 was 0-4-2 side tank rebuilt from a tender engine built in 1887 by Sharp, Stewart and Co. The cylinders were 16 in. by 22 in., and the coupled wheels 5 ft. 0 in. ; the total heating surface is 784 sq. ft. This engine is now the oldest on the line, and is only used as a spare for shunting work. There were four 0-6-0 tender engines which are used for both goods and passenger work; the oldest is No. 26, built by Beyer, Peacock and Co. in 1892; the cylinders were 17 in. by 24 in., and the coupled wheels 5 ft. 0 in. ; the total heating surface is 979 sq. ft. No. 14 came from the same makers in 1904; the cylinders were 18 in. by 26 in., coupled wheels 5 ft. 0 in., wheelbase 15 ft. 2 in.; total heating surface 1,248 sq. ft., and the weight in working order, 40 tons 18 cwt. No. 10, Beyer, Peacock & Co., 1914, was illustrated in Issue for February 1914, p. 29. The dimensions were similar to No. 14 with the exception that the boiler was larger with a total heating surface of 1,360 sq. ft., and the weight in working order is 44 tons. Finally in 1921 an almost similar engine, No. 4, was built by Beyer, Peacock and Co but with a total heating surface of 1,483 sq. ft. The last two engines were usually employed on the heavy summer excursion trains to Newcastle; these often load edto fifteen six-wheelers, and the return fare, for 75 miles was but Is. 6d. third class. No. 29 was a 0-6-4 side tank built by Beyer, Peacock & Co. in 1923 for shunting work in Belfast goods yard; it was illustrated in VoL 29, page 317; the cylinders were 17 in. by 24 in., coupled wheels 4 ft. 0 in., total heating surface 1,064 sq. ft.; tanks 1,350 gals., weight in working order, 55t tons. The two Diesel locomotives carried the numbers 2 and 28. The former worked stopping trains round Belfast, and the latter was usually on the Ardglass branch. It will be noted that none of the locomotives were superheated.

Driving wheel slip. 84
The Baltimore and Ohio Railroad carried out a series of investigaeions into the damage resulting to raids from the slipping of driving wheels. These investigations showed that when slipping occurred to such an extent that the rails became burned it was necessary, on the average, to replace at least three rails. As this is naturally an expensive matter the Company have endeavoured to eliminate it by instructing drivers Ito apply sand previously to coming to a stand, open the sanding gear before the regulator, and handle the latter carefully after starting.

Early Stephenson Engine. 93. iillustration
The Melbourne and Hobson's Bay Railway Co. hold the honour of having built and worked the first line of railway in Australia, their line from the metropolis to Sandridge (now Port Melbourne), a distance of 2¼ miles, having been opened in September 1854. Actually the first running was done with a small improvised locally built engine, but the real locomotive stock was Stephenson built, commencing with 2-4-0 well tanks, followed later by 4-4-0s.
In addition, two engines of uncommon type for shunting on "Sandridge Pier" were imported from the same makers, one in 1859 and the other in 1875. The first of these, No. 5, is depicted in the accompanying picture of a very faithful model made in 1869, and quite recently made over to the Railways Department by Professor Wilfred Kernot of Melbourne University. It is intended to locate it in a glass case at Flinders St. station, Melbourne, now one of the greatest suburban traffic centres of the world, but even more celebrated in the enthusiast's eyes as the starting point for Australia's historic first train mentioned. The model depicts the details so clearly that it is hardly needful to give more than a few dimensions of what. was No. 1177 in Stephenson's list. Her drivers were 3 ft. 9 in. diam., cylinders 8 in. by 14 in., boiler pressure 130 lb., weight 101 tons, and tractive power 1,998 lb. The heating surface was 330 square feet, with 5¼ square feet of driving grate (from which it may be gathered that an automatic stoker was not required). This engine and her similar though larger mate, No. 24, continued as Pier Donkeys for ten years or more after the acquisition by the Government Department, but thereafter came a period of retirement, from which she was bought by the contrac- tors for the Outer Harbour works at Adelaide, South Australia, and eventually she came to her end about 1910.

The Webb compounds. James H. Anderson
In the issue of March 1938, at· page 90, F.C. Hambleton refers to F.W. Webb's. Teutonic class of locomotives, ten in number, all of them named after White Star liners except No. 1304, which was. named Jeanie Deans. Alfred Rosling Bennett (an ortginal member of the Institution of Locomotive Engineers) was Chairman of the Engineering Section of the Edinburgh International. Exhibition of 1890, and worked very hard d to make it the success it was, and the railway section was particularly' good.
Bennett .interviewed Webb to get him to send a locomotive to the Exhibition which at first he seemed disinclined to do unoifhe heard that Mr. Worsdell had promised to send' one of his latest compounds.
When Webb did promise to send an engine he asked what name hould be given ,to it, and Mr. Bennett at once' suggested "Jeanie Deans."
I knew Bennett—he was very pleased at this—he looked, upon it as a compliment not only to himself but also to—Edinburgh and to the memory of the author of The Heart of Midlothian.

The fourth edrtion of this work, edited and revised by H. Wright Baker, contains little of the or.iginal book, but great care has been taken to retain the author's intention to give in a complete and concise form the thermodynamical' principles of the subject.
In addition to the new material incorporated, dealing especially with internal combustion engines, refrigeration and heat transfer, the whole book has been replanned to present a logical development of the subject. The figures and diagrams are nearly all new and many worked and unwor ked examples are included. A feature most helpful to the elementary student is the marking, by means of an asterisk, of the simpler sections in order that these may be read first. This work deals with the principals in a thoroughly logical manner.

Locomotive facts and figures. 95
Despite their formidable tabular array, the annual financial reports and statistical returns of the four main line British railways always present facts and figures which when analysed afford a good deal of interest from the locomotive point of view. The returns for the year ended December 31, 1938—-one of the most difficult in the history of the industry—are no exception in this respect.
Due to standardisation and the weeding-out of obsolescent types which have been and are still being replaced by units of greater power, contraction of locomotive stocks has been a feature of British railway practice ever since the amalgamations of 1923 began to take a practical effect. This characteristic is again evident during the year under review, the total number of steam locomotives owned by the four main line railways having declined from 19,679 at the end of 1937 to 19,577 at the end of 1938. For this net decrease of 102 the two northern groups are primarily responsible: the L.M.S. having reduced its stock by 44 engines and the,L.N.E.R. by 58. At 3,630, the Great Western s stock shows a decrease of only two, whilst, despite Its great progress with electrification — the Southern Railway with 1,816 steam locomotives actually shows an increase of two. On the L.M.S., two wheel-arrangements which became extinct during the year were the 4-4-0 tank and 0-6-4 tank.
There was no change during the year in the total number (37) of internal combustion locomotives owned by the four main line companies, but under the headmg of Rail Motor Vehicles (which includes electnc or internal-combustion passenger-carrymg units) there was an increase from 1,882 to 2,002, due mainly to the larger numbers of electric units employed on the Southern and L.M.S. Railways—in the latter case, of course m connection with the Wirral electrification which came into. operation during the year. The L.M.S., which still operates five steam rail motor vehicles, also acquired three new Diesel units the former type is now extinct on the Great Western and the Southern only possesses one, but no fewer than 80 figure m the L.N.E.R. return. (All the foregoing figures exclude service units). The year 1938 had been looked forward to by the railways as being likely to prove at least as good as its predecessor, but due to the trading set- back (Itself the outcme of international troubles) and the intensification of road competition, the very reverse proved to be the case, and in the result the year turned out a truly disastrous one. Railway administrations were therefore forced to turn to economy after a period of expansion, and at a time when the costs of stores and materials were higher. Locomotive running expenses were affected both by the increased cost of coal and by higher rates of wages, so that in the aggregate the locomotive runnmg expenses of the four main line compames exceeded those of 1937 by about £510,000. Having regard, however, to the fact that the ttal locomotive running expenses of the British railways reach the astronomical figure of nearly £33,000,000 annually, this increase may be regarded in the circumstances as commendablv small. Under. the heading of " Fuel," the only company which does not show an increase in its locomotive running expenses is the L.M.S., and some highly interesting remarks on this aspect were made by Lord Stamp, the chairman of the com- pany, at its annual meeting recently. Lord Stamp told the shareholders that the increased price of locomotive coal represented a sum of no less than £201,750, but this was turned into a net gain of £83 by economies, to the total value of £201 833 m the quantities of coal used. Towards these economies, decreased mileage contributed £153.104, and .decreased consumption per mile, £48,/29. Bearing in mind that the railway concerned has made so much progress in the acceleration of Its services, the last-named figure is particularly interesting as indicating the beneficial results of introducmg more efficient engines, and of encouragmg the staff in the thrifty and intelhgent use of fuel

New express locomotives: German State Railways. 96. illustration
Two locomotives delivered from the Fried. Krupp Locomotive Works in Essen to the German State Railways were intended for hauling "D" express trains of 650 tons, consisting of 14 coaches and luggage van, at improved speeds. The engines were undergoing running tests. The leading dimensions were given.As will be seen from the photograph, a streamline covering was fitted for appearance and reducing wind resistance. The working pressure was 284 psi and to keep down weight the boiler was constructed of special alloy steel. The firebox is of Krupp steel known as Isott H. The engine being of the three-cylinder type, the inside cylinder drives on to the first, and the two outside cylinders drive on to the second axle. Special braking equipment had been provided in view of the high speeds anticipated.

Electric trains for the L.N.E.R.  96
The L.N.E.R. had placed contracts for the passenger stock to Ibe used on the lines 'being electrified between Liverpool Street and Fenchurch Street and Shenfield, and between Manchester and Glossop. The new coaches of all-steel construction and of the open saloon type and fitted wiIth electro-pneumaric doors which may be opened by the passenger pressing a button, or may be controlled by the train staff. Contraots placed for 100 60ft. motor coaches and 100 55ft composite trailer coaches with the Metropolitan Carnrnell Carriage and Wagon Co. Ltd., and for 100 55ft. driving trailer coaches with the Birmingham Railway Carriage and Wagon Company Ltd. Orders had also been placed with the English Electric Company Ltd. for 92 three-coach electric train equipments for the Liverpool Snreet/Shenfield trains, and with tlle General Electnic Company for 8 three-coach electric train equipments for the Manchester /Glossop trains.

Following recent experimental runs on the Oxford and Cambridge Branches the strearnbined 3-car Diesel articulated train was .in regular passenger service between London (St. Pancras}, Luton, Bedford, Kettering, Leicester, Nottingham and intermediate stations; taking the place of existing steam trains and provided London with its first regular Diesel passenger service. During a recent journey it covered the 15.2 miles between Bedford and Wellingborough in 15 minutes 48 secs., representing a gain of 2½ minutes on schedule. A speed of 75 rn.p.h was reached on the 1 in 119 gradient after passing Sharnbrook.

The following 4-6-0 engines had recently been completed at Swindon: No. 5088 Llanthony Abbey, No. 6860 Aberporth Grange, No. 6861 Crynant Grange, No. 6862 Derwent Grange, No. 6863 Dolhywel Grange, No. 6864 Dymock Grange, and No. 7819 Hinton Manor. Two 4-4-0 express engines, Nos. 3223 and 3224, also seven tanks had been put onto service. The tanks were No. 7250 (2-8-2), No. 3101 (2-6-2) and Nos. 3607 to 3611 (0-6-0). Recent withdrawals included No. 3370 (4-4-0) Sir William Henry, and No. 3378 (4-4-0) River Tawe.

New streamlined 4-8-4 express locomotives, Victorian Railways. 98.
To obviate double-heading of heavy passenger trains on the Western main line between Melbourne and Ararat (131 miles), three expness locomotives of the 4-8-4 type were to be constructed at ,the Railway Workshops, Newport, Victoria. These locomobives known as class H, and would be the largest, heaviest and most powerful in the Victorian Rlys. service; capable of a maximum speed of 65 m.p.h. The estimated tractive effort at 85 per cent. of the boiler pressure is 55,000 lb., and the total weight in working order, with tender, approximately 261 'tons. They will have three cylinders each 21½ -in. dia. by 28 in. stroke, and coupled wheels 67 in. dia. The cylinders will be three-piece steel castings, the centre cylinder ,being located forward of the two outside cylinders will drive the leading coupled axle. The two ctutside cylinders will drive the second pair of coupled wheels. Cast iron liners will he fitted in all cylinders. The frames were cast steel bar type, made in Australia. The frame stays will also be cast steel. The overall length of engine arid tender will be approximately 92 ft. 6 in. and the total wheelbase 82 ft. 1 in. The maximum axle load will be 23 tons on the coupled wheels. The modified Belpaire type boiler will be of liberal dimensions and all-steel construotion, with a welded firebox with itherrnic syphons. The 'boiler pressure of 220 lib. will be higher ,than that of any existing locomotive :in Australia. The grate area win be 68 sq. ft. A mechanioal stoker of the Simplex improved 'type B fitted, the engine of which will be located on the rear of the engine frame. Roller bearings will be utilized for the engine bogie and trailing truck axles, and also for tender bogie axles. The locomotive trailing ,truck will be of a new type, fabrlcated .from mild steel plate by electric-arc welding. The outside valve gear will be of the Walschaerts type, actuating large-diameter, long-travel piston valves. The inside cylinder valve will derive its motion from an improved type· of conjugated gear driven from the outside valve gear, behind ,bhe cylinders. The power reverse gear will be of the pneumatic 'type. The Westinghouse air brake equipment wiil be of the A-6-ET ty.pe. The rectangular type tenders wiil be carried on six-wheel ,bogies and will have a capadtyof 14,000 gallons of water and 8 tons of coal.

Concluded from page 56. Some additions to the accounts of Sinclair's 2-4-0 or Class Y engines, illustrated in Vol. 14., page 61, should be referred to before completing these notes. The earliest of those built by Neilson's had feed pumps only, driven by eccentrics. They did not have the half round beading between the chimney and its base nor the circular opening in the middle of the driving splasher. A photo. of what was probably the first engine of the class appeared in Issue of December 1938, p. 384. Fig. 53 illustrates No. 317, the eleventh engine of the series, showing injectors and Johnson's number plates. It is interesting to note that the first E.C.R. locomotive to be fitted with injectors was No. 308 of this class.
Fig. 54 shows No. 336, one of the five engines rebuilt by Adams, with boilers made by Neilson's, described in Vol. 14, p. 100. These were Nos. 309, 336, 346, 347 and 364. The smokeboxes were carried down to the footplate with a concave curve covering the exhaust pipes. In the 'eighties, No. 336 worked local goods in the Stratford district. No. 309 had at the end of her career as No. 0309, a second hand boiler put in, probably out of No. 313, withdrawn in 1885, to keep the engine in service a little longer; this had an inclined bottom to the firebox as had also that· in No. 364. This engine at the time had a cab· like No. 353, see Fig. 115, Vol. XIV, p. 138. We have now reached the period when, on July 1, 1862, the Eastern Counties Railway and other component companies (see the Locomotive Mag., Vol. 6, page 90) were incorporated as the Great Eastern Railway. It is a matter of regret to the writer that, owing lo lack of space, a lot of the matter at his disposal has not been made use of, and on that account the notes are not as extensive as they might be.

The first railway in China: Shanghai and Woosung. 112-14. 3 illustrations
Involvement of Sir Robert Macdonald Stephenson and Richard Rapier of Ransomes & Rapier Ltd. year 1863-64, Sir Robert Macdonald Stephenson, who had done much for the development of railways in India, visited China with the object of establishing railways in that country. He was received with great enthusiasm, and it looked as though railways must soon be introduced. Sir Robert Macdonald pointed out the chief features as a basis for his proposals. These were: 1. China was so deficient in roads and canals, and these were so often out of repair that she needed railways, and would therefore benefit by them more than any other ,country. 2. The physical features of the country were admirably suitable for the purpose. 3. Most materials and labour of all kinds were available in China, and therefore the railways might be construc- ted by the Chinese themselves. 4. Financial arrangements could be made by an English house as the rail ways were certain of success. 5. The railways would afford the Chinese Government and authorities the finest 'facilities for collecting legitimate taxes. (Note.-Local Governors had opposed railways on the grounds that they would interfere with their privi- leges in turning the local taxing powers to their best accoun t) . 6. The railways would not wholly displace canals, and give much more employment than they would take away. However, Sir Robt. Macdonald Stephenson had visited China on public grounds, and consequent- ly proposed extensive schemes, being anxious to prevent mistakes and extravagances such as had occurred in the construction of railways in other countries. Nothing came of his scheme, probably due to its elaborate nature. His proposals embodied a scheme for rail communication from Pekin to Calcutta, and it was more than likely that his intentions were misunderstood. In view of the non-success of Sir Robert's extensive schemes, it now seemed to some of those interested that 3- short line, in one of the ports more amenable to European influence, might be more successful. Therefore, in 1865, a company was proposed with the object of constructing a railway from Shanghai to Woosung, with a jetty and bonded warehouses at the latter place. The passage of large vessels up the difficult and· changeable Yangtse to Shanghai would thus be avoided. The firm of Messrs. Jardine and Matheson had made various attempts to introduce railways to China but without success, so they finally thought the only way to make a railway would be to quiet- ? ly acquire land and make the line as a private undertaking, under their sole control. Messrs. J. M. proposed to construct a road of some sort from Shanghai to Woosung, and the acquisition of the necessary land was a difficult and tedious process. In 1872, Richard Rapier, of Messrs. Ransomes and Rapier Ltd., Ipswich, thought that a step might be gained by sending some engines and carriages and rails to the Emperor of China on the occasion of his majority and marriage. (He was quite ignorant of Messrs. Jardine and Matheson's scheme). However, his scheme was not adopted for diplomatic reasons, and finally due to the death of the Emperor after a year and a half of his assumption of personal government. Richard Rapier still felt some opportunity might occur for introducing a railway in China, and in view of being ready for such a chance de- signed and built at Waterside Works, Ipswich, a locomotive which should be strong enough to take a decent load, and yet be small enough to pack in a case for sending out to China for trial and exhibition. The loco. was commenced in the autumn of 1873, and as there was no hurry it was not finished until a year later. A brief description of this locomotive (Fig. 1) is as follows:- Wheels Cast iron, 18 in. in diam. Cylinders 4 in. diam. by 6 in. stroke hornblocks were fitted, the axleboxes running direct in the slots. . Valve Gear ... Stephenson, the eccentrics were simple, being flanged discs with one flange loose to enable straps which were solid to Ibe slipped on. The loose flange was afterwards bolted on. . Feed pump 'between frames, and driven by eccentric from rear axle. This eccentric was of similar construction to the valve eccentrics. Length over Frames ... 6 ft. 0 in., the tender was of similar length. Gauge 2 ft. 0 in. Weight in working order 22 cwt In the spring of 1875, two of the directors of the Woosung Road Co. (which had been formed for the construction of a railway along the pro- posed Shanghai-Woosung Road, with a capital of £20,000 after paying for the land) visited Ipswich to see the little locomotive. Running on a circle of only one chain radius,

Institution of Locomotive Engineers: air conditioning of passenger stock. 114-
Precis of Paper 405 by A.H. Chilton: Meeting in London on 22 March 22. The following is a brief summary. Until comparatively recent years, railways had laboured under the disadvantage, by comparison with hotels and ships, that no matter how luxuriously stock may be equipped, the presence of noise and dirt, inseparable from the railway track and motive power, permeated the passenger space. Therefore, however attractive the furnishings and fitments and other amenities may be, and however smoothly trains may run, the comfort and well-being of the passenger is generally adversely affected by the infiltration of air un- pleasantly laden with dust, the products of combustion and the noise consequent upon open win- dows and the absence of insulation.
The development and historical aspects of the subject were dealt with, and in this connection it is interesting to note that one of the earliest efforts in this country was an evaporative system which was tried out on the Southern Belle in 1908.
It was emphasised that window construction is important, and considerable development is taking place in the production of suitable windows. These are usually double glazed, and in the more advanced window the air space between the glazing is sealed and dehydrated. In the luxury class of window, interesting developments are taking place, viz.: on the Union Pacific Railway of America, cars have been fitted with windows made up of two sheets of polarised glass, so that when the inner glass is rotated through an angle of 90 deg., the window becomes non-transparent.
Referring to the matter of air supply, treatment and distribution, the author said that the outside air quantities should be in the neighbourhood of from 10 to 20 cu. ft. per. minute per person. Usually the total amount of air in circulation is in the vicinity of two to four times that of the outside supply, and it follows that this quantity must be sufficient to absorb the heat gain in the car and bring about the desired internal state. A further consideration is that the minimum limit of outside air must be sufficient to maintain the requisite internal pressure. The necessity of cleaning filters was then mentioned, and the method of doing so described. In extremely dusty climates separate filters may conveniently be carried as spares. Turning to methods of distribution, the bulkhead, centre duct and roof plenum chamber methods were illustrated. In general, one cannot lay down a hard and fast law for the most suitable method of distribution, as car construction so largely affects this problem. The control of an equipment is extremely im- portant, and the common statement "an air conditioning equipment is only as good as its con- trois," is very true.
Since the return air is an accurate measure of the state of the car content, it is usual to locate the controlling thermostats in the return air circuit. These thermostats in turn control the operation of the refrigeration or of the heating equipment as may be required.
The Author next referred to refrigeration sys· tems, mentioning that the refrigerant commonly used with mechanical refrigeration systems is Freon, which is non-toxic, colourless, non-corrosive, non-inflammable, and possesses a temperature pressure characteristic very suitable for rail- way applications. By means of a graph the characteristics of other common refrigerants were also shown, the nearest to Freon being methyl chloride. The electro-mechanical and direct mechanical systems, which so far as their refrigeration details are concerned are comparable, were illustrated by a schematic diagram. The subjects of refngeration components, refrigeration units, compressors and power equipment for the systems mentioned in the paragraph above, were dealt with, reference also being made to the ice activated and steam ejector systems
The paper, which was well illustrated through out, concluded with a reference to power con- sumption and a summing-up as to the most suit- able system to adopt for particular conditions.

Five miles long, built to convey limestone from the Forcett Quarries and opened in 1867. The engineer was William Bryson and the contractors Trowsdale & Sons of Stockton. It branched off the Darlington to Tebay line.The line has no great engmeermg features beyond the Tees viaduct, but there are altogether 18 under or over bridges. One feature about the Tees viaduct is the extreme lowness of the parapets, about 12 in. high only. From its inception, the line was worked and maintained by the Central Division of the old N .E. Ry. and no regular passenger traffic has been worked over it, although the engineer's saloon pays an occasional visit to view the track, etc. The engine shed at Eppleby accommodates the shunting engines, owned by the Forcett Quarry Company. The first engine they possessed was built by Fletcher, Jennings & Co., in 1867. It was an 0-4-0T, outside cylinders. 10 in. by 20 in., and named Whitehaven (WN 76).
By 1900, the company had been reorganised as "The Forcett Limestone Co. Ltd.," and they replaced the first engine with two Hawthorn, Leslie & Co.'s standard 0-4-0T's outside cylinders., 3 ft. 6 in. drivers, 14 in. by 20 in. cylinders.; they were named East Layton (2457/1900), and Forcett (2465/1900). In 1911, the former was. replaced by a slightly larger four wheeled saddle tank engine with outside cylinders from the same makers. She was also named East Layton (WN 2871/1911) and had 3 ft. 6 in. wheels, 14 in. by 22 in. cylinders. These two engines were stabled at the shed, and as they run over the Forcett Railway to the quarries, a telegraph was installed to prevent the L.N.E.R. engine being on the line while they are proceeding to work. There is a fair amount of goods and coal traffic, and the L.N.E. train does a trip on Mondays, Wednesdays and Fridays, leaving Darlington at 09.15. This train also served the Barton branch (old Merrybent Darlington Railway), and is generally worked by class "J77" No. 1033, which was originally built at Darlington in June 1877, as one of Fletcher's B.T.P. class, and rebuilt at York in 1899 as an 0-6-0T shunter. A heavier engine  was not allowed on these branches.

Continued from page 79). The ninth loco. was purchased from the Yorkshire Engine Co. in 1902, and was, in general type, a four-wheeled saddle-tank, with side bunkers, a working pressure of 140 lb. per sq. in., and a cylinder diameter of 14 inches. The tractive effort was probably about 11,000 lb. and this was considered sufficient for the newly arising "charging-box" traffic at the steelworks. With the later extension of mechanical charging to all the open-hearth furnaces and the consequent increase in outputs, however, the traffic became excessive for the power and adhesion of the four-wheeled locomotive. Towards the end of the war, after about 15 year'. service at Frodingham, old No. 9 was sold to a neighbouring works.
Frodingham Locos. Nos. 10 and 12. The tenth loco., No. 10, was purchased from Andrew Barclay & Sons , in 1904. A sister loco., No. 12, was obtained from the same source in 1905. Both had tractive efforts exceeding the previous maximum on the works. New boilers were provided in 1924 and 1925, with increased working pressures and tube diameters. Main dimensions are listed below:- Steam Pressure-Original (1904-5) 140 psi Present (from 1924-5) 180 psi. Tube Heating Surface-Original 568 ft2. Present 612 ft2. Firebox Heating Surface 64.6 ft2 Total Heating Surface-Original 632.6 ft2. Present 676.6 ft2. Grate Area 11.5 ft2 Tank (Saddle-type) 750 gals. Cylinders (outside-type Diam 15 in. Stroke 22 in.

Gross weight (full working order)- Originnl (approx.) 35 tons Present 38.3 tons The two locos. were intended to handle the furnace material traffic, largely on the "drops" (bunker) inclines. In operation they have been found remarkable for their high starting effort, and "bulldog" tenacity at low speeds. Restricted boiler dimensions resulted, however, in limited speed or marked "priming" under heavy load, and it is unfortunate that higher steaming capacity had not been specified.
The two locos. were found of great value, for annother purpose, after the introduction of "car-casting" at Frodingham in 1917. This process nvolved the repeated short-distance movements if ingot-casting-cars, each of 40 tons laden veight, over routes including curves of 140 and 160 ft. radius. The cars, built to resist splashng by molten steel, were low, small wheeled, close-coupled, and dead-buffered. Inertia against .tarting was very high and conditions required :hat sets of four and sometimes eight cars should )e handled without division. The low central buffers of the cars required corresponding provision on all locos. used to handle them. Unfortunitely it was found impossible, at the time, to devise a spring loaded central buffer which was sufficiently durable and adaptable to existing frames, Serious damage resulted to the structure of several locos. which were then equipped with olid central buffers on' deepened buffer planks.  When so equipped, in 1918, Nos. 10 and 12 were found to experience relatively little damage, owing to their heavy main frames and general build. During replacements, less of buffer planks was increased gradually to 11 in. (mild steel). With the increases of working pressure, in 1924-5, the nominal tractive .fforts were raised to 16,706 lb.
Increases in tube iiameters provided some increase in heating surfaces, but the higher efforts can only be considered available over the shortest distances or at lery low speeds. Though recently regarded only as spare locos., Nos. 10 and 12 must be credited vith valuable service in the ingot-casting traffic iver a lengthy period. Between the arrival of the two locos. described ihove, the eleventh unit of the fleet was purchased, second-hand, in early 1905. This loco., Old No. 11, was built by Black, Hawthorn in 1877, and was of six-coupled, saddle-tank type, with a working pressure of 120 psi., outside cylinders of 15 inch diameter and 22 inch stroke, and a gross weight of about 34 tons. The wheelbase was 11 ft. 10 in., and the wheels were of 3 ft. 8 in. diameter. The duties performed by this loco., which was of very considerable age on arrival, were limited to mill shunting. In 1924, it was scrapped after standing in disuse for a year or two.
Frodingham Loco. No. 13.
The thirteenth loco. was purchased from Hudswell, Clarke & Co. Ltd., late in 1905. A new boiler was provided in 1929. Details of the loco. are listed below;- Steam Pressure-Oniginal Present (1905) 150 lb. ~er sq. in. (from 1929) 180 lb. per sq. in. 142 at 1~ ill. 142 at 1~ in. 552 sq. Ft. 595 sq. ft. 67.7 sq. r-.

The design of the steam pas- sages, cylinder valves, etc., was also such that the loco. has always been found "sharp" and speedy. The duties performed were various and included "mines" haulage in the earlier years. In the late pre-war years, No. 13 was found the most suit- able unit for handling the growing blast furnace slag traffic, though rarely available for this purpose.
The fourteenth loco. was provided for blast furnace slag traffic in 1906, and was obtained from Andrew Barclay, & Sons .

The total heating surface and grate area were low, however, even with 160 psi. working pressure, and the steaming capacity proved, in practice, to be insufficient for the slag bank traffic. From 1917 the loco. was used for general shunting duties, limited in recent years to mill shunting. Frodingham traffic now requires few 14 inch locos., and No. 14 was scrapped on requiring heavy repairs, early in 1938. ( To be contznued).

Clogher Valley Railway.
This line, of which an illustrated description appeared in the Locomotive, Vol. 19, page 276, scheduled for closing down. It was of 3 ft. gauge, running for most of its length of 37 miles alongside the public road, and since 1928 had been operated by a joint committee of the Tyrone and Fermanagh County Councils. Several changes have been made since the article referred to appeared; of the six original locomotives built by Sharp, Stewart & Co. in 1886/7, two, Nos. 1 and 4, had been scrapped, while No. 5 was dismantled. These engines are of the 0-4-2T type, with cylinders 13½ in. by 18 in., coupled wheels 3 ft. 0 in., trailing 2 ft. 3 in., wheelbase coupled 5 ft. 7 in., total 10ft. 4 in., total heating surface 514 sq. ft., tanks 600 gals., weight in working order 23 tons 16 cwt. It had been the custom to run bunker first, in order to obtain a better look-out for the driver. They are fitted with Joy's valve gear, the only example of this gear in Ireland, though three engines on the Cork & Muskerry Light Railway (now dismantled) also had it. No. 7 locomotive, a 0-4-4T built by Hudswell, Clark & Co. in 1910, was scrapped in 1934. No. 8 was an Atkinson-Walker steam tractor built in 1928, which is now running on the County Donegal Railways as No. 11 Phoenix; it was illustrated in the Locomotive Mag. for February 1939 [KPJ: this cross reference appears to be incorrect]. Finally, there is a Diesel rail coach and a similar engine, but with tractor body, both built by Walker Bros., Wigan, in 1932. These were illustrated in the Locomotive Mag, Vol. 39, page 8, and Vol. 40, page 8. The power unit is of similar type to those running on the County-Donegal Railways. Most of the train services on the line are now maintained by these units, the tractor hauling a passenger coach as trailer. Only one steam train is now normally in service except on special occasions, such as fair days. The service has been considerably accelerated by the use of Diesel units. In 1935, on the closing of the Castlederg and Victoria Bridge Tramway, one of the engines, a 2-6-0T built by Hudswell, Clark & Co. in 1904, was acquired by the Clogher Valley Railway. It was rebuilt at Auchnacloy shops as a 2-6-2T, an illustration and particulars appearing in the Locomotive, Vol. 42, page 242, so further reference is unnecessary here. Since 1928 there has been only one class of coach, the first class being abolished.

Five of the new series of 2-8-0 ·standard freight engines (Class  8F) had so far left the Crewe shops, Nos. 8111-15. At Derby the first of the new 0-6-0s had been completed, No. 4577. The engines in this series were to be fitted with 3,500 gallon tenders, which are being exchanged for new 4,000 gallon tenders with ngines of the Silver Jubilee class as they passed through the shops. A series of 0-6-0 heavy-oil shunting locomotives was also now under construction at Derby and numbered from 7080 up. No. 5522 of the 4-6-0 Patriot series (Class 5XP) had been named Prestatyn. Two ex- L.N.W. G1 class 0-8-0s have recently been rebuilt with standard Belpaire boilers, Nos. 9135 and 9365. Recent withdrawals of interest include 4-4-0) George the Fifth. class, No. 25362 Fire Queen, and 0-6-0 Special tank No. 27334, Liverpool, the latter having completed forty-four or sixty fourr years' service. Other withdrawals were: 4-6-0 Prince of Wales class No. 25752; 4-6-2 superheater tank No. 6960; 0-6-0 Coal Class No. 28099; 0-6-2 Coal tanks Nos. 7764 and 7799; and 4-6-4 Baltic tank No. 11113.

Death of Williarn Cowie, retired Locomotive Inspector of the Highland Railway. He was 68 years of age and had 48 years' service when he retired three years ago. Cowie had charge of the Royal Train on several occasions between Perth and Inverness, and could boast that he had driven at one time or another almost every engine of the old Highland including singles Nos. 12 and 32. An exception was the Findhorn Branch tank. L.M.S Illustration: No. 14402, Ben Armin with Cowie in foreground (A.C.W. Lowe)

American locomotive buildlng. 123
The United States Department of Commerce issued figures showing the position of locomotive orders, both for home and abroad, during January 1939. During that month the leading manufacturersdelivered 23 engines and had in hand orders for an additional 91. This compares unfavourably with the corresponding month for the previous year, when 35 were delivered and 156 on order. Of the 91 locomotives on order this January only 11 were steam, 24 being electric and 56 oil-electric.

American locomotive fuel efficiency. 123
The President of the Association of Amerioan Railroads has stated that the railways of .the United States during 1938 required on the average 115 lb. of fuel to haul 1,000 tons of freight and equipment over a distance of one mile. 14.9 lb. of fuel were necessary to move a passenger car over the same distance.

G.W.Ry.-Old Oak Common Locomotive and Carriage Depot. 123
Had been undergoing enlargement for the past five years and will be completed this month. The depot covers over 100 acres and is the largest of its kind in this country. Some 450 engines and 2,000 carriages are dealt with daily by a staff of 1,700. There are separate up and down lines for working empty stock between Paddington and the depot with automatic signalling throughout the 3.5 miles. A 70-ft. turntable is provided and five signal boxes control movements. In all there are 15 miles of sidings.

Wemyss Coal Co. locomotive. 124. illustration
Coal had been mined in Fife from a very early date, certainly since the twelfth century, and in November 1428 there is a record of the raising of coal at Wemyss. David, second Earl of 'Wetnyss, obtained a charter from King Charles II and. built Methil harbour, thereby establishing an extensive export trade. A number of collieries had since opened on the Wernyss Estate, which had continued throughout in the same family ownership. R.E. Wemyss obtained a Board of Trade certificate to construct a private railway, which was opened from Thornton to Buckhaven, 4¼ miles, on 8 August 1881, and worked by the N.B.R. To facilitate the export business this was soon extended to Methil, a further 1¼ miles, and a new dock constructed at the latter place. The railway, hitherto known as the Wemyss and Buckhaven, was from the opening of the extension on 5 May 1887, known as the Methil Ry. Both railway and dock were sold to the N.B.R. on January 11, 1889, and on 17 March 1894, the Wemyss Coal Co. Ltd. was registered to work the minerals on the Wemyss Estate. The present chairman of the company, Capt. Michael Wemyss, is a direct descendant of David, the second Earl, previously mentioned. The company has formed an extensive system of railways connecting their collieries With the harbour at Methil, where two further docks have been completed by the North British Railway. They are the owners of a stud of locomotives, of which No. 6) is shown in the illustration. This engine, formerly G.N.R. No. 601, was one of a very numerous class first built in 1874, and had 4 ft. 7 in. wheels on a base of 15 ft. 6 in., of which 7 ft. 3 in. were between the leading and driving and 8 ft. 3 m. between the driving and trailing. The cylmders were 17½ in. by 26 in. and the boiler had a length of 10ft. 1 in., with a minimum external diameter of 3 ft. 10½ in. The saddle tank held 1,200 gallons of water, and the working weight was about 40 tons. The engine was built at the Doncaster Works in 1875 and was sold during the period of the Great War to J.F. Wake, of Darlington, who reconditioned it for the Wemyss Coal Co.

Recent accidents. 124.
Wishaw. Thc Inspecting Officer of the Ministry of Transport issued the report upon the accident which took place on 4 August at Wishaw South Station, situated on the L.M.S. main line dram Carlisle to Glasgow Central. A special freight train from Carlisle overran signals on a falling gradient and collided at about 20 miles an hour with the rear of an empty passenger train. The driver of this latter train who was alone at the time was thrown off by thc impact and his engine, with the regulator open, broke away. After travelling some 3½ miles it overtook a passenger train, partly wrecking the last coach and killing thc guard. The Inspccting Officer found the prirnary cause of this series of accidents was the inability of the driver of the frpight train to stop at signals, which may have been contributed to by under estimarion of the load. A signalman is also mentioned for hls failure to observe that there was nobody on the engine when it passed him, especially as it was running tender first.

L. M. & S. Ry. 124
Dr. Leslie Burgin, Minister of Transport, made a trip on the footplate of No. 6226 Duchess of .Norfolk, with the down Royal Scot Express as far as Blisworth. A special stop was made there for Dr. Burgin to alight and return on a homeward run. Although permanent way checks caused delays between London and Tring a fine run was recorded, the 62.8 milcs being covered in 65 minutes. The train consisted of eleven coaches, approximately 350 tons.

Locomotive management, cleaning, driving, maintenance Jas. T. Hodgson, and the late John Williams. Revised by Chas. S. Lake, London: The Railway Gazette, 500 pp. 105 half-tone illustrations and 195 line drawings.
As its title indicates, the work is a manual intended for the use of locomotive eng,inemen and those in training for the responsible duties associated with that calling. It will be found also of considerable assistance to members of the running shed and shop staffs whose work brings them into daily contact with the preparation and maintenance of locomotives.
Details are clearly illustrated and described in the book, and there are special chapters devoted to the regulations affecting the movement of engines and trains in traffic. Questions and answers on locomotive breakdowns have been brought up-to-date.
The book contains a large number of half-tone illustrations of modern locomotives, and the tables of dimensions given below each are a useful feature for ready reference. In the appendix typical footplate views are shown of various loco- motives in service in this country with the fittings numbered and key lists provided giving the function and name for each part

Diesel locomotives and railcars..Brian Reed, London: Locomotive Publishing Co. Ltd.
Advantage has been taken when preparing the second edition of this work to include considerable additional and recent information. A large amount of development has taken place since the first publication of this /book, and the more outstanding of the achievements are described and illustrated. Among the many who will find it of value are those contemplating changing over to this form of traction, but who are as yet undecided. Great care has been expended in compiling tables and data of comparative operating costs and the advantages are defined with clar ity and accuracy. In the section devoted ·to railway requirements, there is now embodied matter relating to Bodies and Framing; in this the technique evolved for the coachwork of railcars is referred to and well illustrated; in fact, the illustrations throughout are of a high standard. This applies not only to photographic reproductions, but also to the line drawings. all of which. are of such a size that the details may be easily followed-by no means a universal thing in modern text-books. This new edjtion will be welcomed by all who desire a comprehensive and reliable review of the subject, and should also be absorbed by those whose prime' est is in other forms of propulsion, for it fairly and forcibly conveys the extent to which the Diesel locomotive and railcar have been developed and the position they occupy in modern rail transport.

Railways, roads and the public. Sir Charles Stuart-Williams and Ernest Short. London: Eyre and Spottiswoode..
Although the railway companies' plea for a square deal must be known to practically everyone by now, it is doubtful if many really appreciate what they are asking for or the grounds on which they claim it. The whole matter is rather complicated and, as in most controversial affairs, there are points on both sides which must be fairly weighed in order to get a just understanding of the case. Railways, Roads and the Public puts all these in a very concise and easily comprehended form and will be found of much use to those who really wish to get a fair and impartial view of the case. Railways are a vital necessity to the country and although, owing to the circumstances explained in the book road hauliers are able to compete with the railways in many cases. on favourable terms, they cannot supersede them, and the importance of keeping them in a sound financial position thus. becomes apparent. The book is divided into four parts, the first being a somewhat lengthy introduction, setting forth. the circumstances that have brought about the present crisis. The second details the various services the railways have rendered to passengers; whilst the third similarly shows how' they have treated industry, whilst the fourth gives the point of view of the railway stockholder. The writers have done good service in bringing out this work at the present time, and the public who desire to do so should avail themselves of this opportunity of becoming conversant with the facts of a, problem which affects the welfare of all.

We have received from Messrs. Shorter Process Co. Ltd. of Celtic Works, Savile Street East, Sheffield, 4, full par- ticulars of the Shorter process for the surface hardening of ferrous parts, together with details of the machines suppliedi by. them for the punpose. This process, which was briefly' referred to on page 6 of this volume, is a preoision method' of hardening applicable to the wearing faces of parts made, of cast iron, forged steel, cast steel, plain or alloyed, pr o-. vided that the metal is of such cornposition that it responds to hardening by hearing and quenching. The surface to be- treated is heated by means of specially designed burners and' afterwards quenched .by a jet of water or air. Results show that maximum hardness is obtained on surfaces so treated' and that the hardness is of considerable depth; the centre COre is unaffeoted and distortion is praotically nil.

Correspondence. 126

West Cornwall Railway. Reginald B. Fellows.
Two interesting items have very recently come into the market and have been purchased by the Railway Club. One is a ticket of admission to a dinner held on Wednesday, 25 August 1852, to celebrate the opening of the West Cornwall Railway, and the other is a quaintly worded notice which was issued with the Dinner Tickets. The notice runs as follows:-

NOTICE.
All persons having Dinner Tickets will bring a Plate. Knife and Fork and Pint Cup. The Dinner will consist of Roast and Boiled Beef, Pudding, Bread and Beer; and those who intend to dine will assemble on the Western Green, at Two o'clock, there to await the arrival of the Procession from the Town Hal!, and then proceed to the Dinner Tables, which will be presided over by the Rev. Henry Batten and Edward Boljtho, Esq.
No one will be admitted without a ticket.

The notice was printed ·by F. T. Vibert of Penzance. It has occurred to me that in view of the recent interesting art icles on the West Cornwall Railway your readers may like to hear of the Dinner Notice.

The steam locomotive in traffic. C.W. Clarke
At page 9 of the January issue, reference is made to a 100-ton locomotive hoist. Both, in the text and at Fig. 34, the hoist illustrated is described as being in use on the South Indian Railway. Actually, the 100-ton hoist illustrated installed at the Bhusawal Shed of the Great Indian Peninsula Railway, and Fig. 34 shows a 4-6-0 type, D/5 class locomotive hoisted for wheeling.
The D/5 class is a modified B.E.S.A. design, placed in service in 1923. They are the last type fitted with the distinctive G.I.P. Railway chimney, before the railway became a State Railway. Works Manager's Office, G.LP. Rly., Bombay.

All the other well tanks had the tanks underslung between the inner frames. The two engines referred to above were for a short local service and the next rebuilding of an engine to tank form was done by Canner in 1858, and later this gentleman made some of the original single drive engines into well-tanks for branch work.

Locomotive design. J. G. B. Sams.
Re leading article of March Issue; the alleged popularity of roller bearings for locomotives; is this a fact outside Sweden? I believe that a few are in use in America and France, but they have a regrettably long way to go before they can be referred to as "popular". I am also a little confused over the question of maintenance and accessibility of freight and passenger engines; my experience has been that the large wheeled engines are if anything more expensive to maintain owing to their higher speeds and the greater care spent on the passenger fleet. It is usual, for example, to examine passenger engines daily, while many Freight and shunting engines have to be content with a weekly look-over. As to accessibility, the greater height from the ground of ,the axles of a large wheeled engine balances out the clearance-below-boiler question and I would suggest that as springs and their gear are usually dealt with from the pit, the question of the awkwardness of the wheels does not arise.

N.E. Railway No. 523. J.W. Armstrong. 126. illustration.
Accompanying photo is one of the numerous 0-6-2T engines designed by T.W. Worsdell for the N.E. Rly., of which the one pictured, No. 523, was buidt at Darlington Works in May 1889, Works No. 77, and was originally a 2 cylinder compound on the Worsdell-Van Borries' system; they had cylinders 18 in. and 26 in. by 24 in. stroke, and driving wheels 5 ft. 1 in. diameter, and classed B. All were later rebuilt as 2 cyinder simples, and in the period 1915-20, many were superheated, including No. 523. The interest of this photo. is that it is taken at Tebay N. E. Rly. shed (which was closed in 1903), and the old lamp, style of painting (needless to say, green), bunker without coal rails, and the compound number plate is discernible on the leading splasher. They were sent to Tebay to replace the 1001 class, with mineral traffic over Stainmore, and were in time replaced by T1 class 0-8-0 in 1902. No. 523 worked many years in the Hull area, and was broken up in 1937, the L.N.E. Rly. classification being N8. Added interest is that the driver was Joseph Armstrong (who had this engine new till 1901) and the fireman was Robert Armstrong, father and son, who were my grandfather and father respectively. .

Canadian National Railways The Royal Train. 147
Cars to form a special train to be used by Their Majesties the King and Queen during their travels in Canada have been prepared at the Point St. Charles shops, Montreal.
The Royal Train has 12 cars altogether, two of them usually reserved for the Governor-General which have been assigned for the personal use of the King and Queen, will be placed in the rear of the train.
One of the cars has two main bedrooms with dressing rooms and a bath, two other rooms for members of the royal staff, and a spacious lounge for the use of Their Majesties. The other car contains a dining room, kitchen and large lounge, an office and two bedrooms with bathroom for members of the staff.
Two of the Canadian National business cars known as Atlantic and Pacific have been remodelled and redecorated for the use of the ladies-in-waiting and the equerries. One of the latest type of standard dining car used on The International Limited, has been included. The train was air conditioned throughout and presented a uniform appearance, the exterior decoration being carried out in royal blue and aluminium with a horizontal gold stripe above and below the windows. The cars in which Their Majesties will travel bear the royal coat of arms in the centre of each car below the window level.
Four locomotives have been prepared for hauling the Royal Train; one of the 6400 class, two of the 6000 class and one of the Pacific type. In the wooded sections of the Rocky Mountains oil burners will be used. Each locomotive will display a plaque bearing the royal coat of arms.
A pilot train, consisting of seven cars, will preceed the royal train.

Institution of Locomotive Engineers. Review of Electric Traction In England. 147-50.
Symposium preented to the Institution at a meeting held in London on 19 April. The following is an abstract.
The subject was divided into four sections; the first of which, devoted to a Statistical Review, was dealt with by W.A. Agnew, Past President, M.I.Mech.E., M.Inst.T., who was also responsible for arranging the whole, and began by referring to the historical aspect. The first practical demonstration of electric traction, with curent supplied from a power station, was made in 1879.
In that year 'Nerner von Siemens, who had constructed a small electric locomotive for use in a coalmine, arranged for it to be temporarily installed at the Berlin Trade Exhibition where it served to haul three small passenger cars round a circular railway. Siemens' railway was later transferred to London where it was demonstrated in the Crystal Palace during 1881.
In the summer of 1883 Sir William Siemens associated with William Acheson Traill, made some experimental runs on the Portrush and Giant's Causeway Railway with a car driven by an electric motor, the current being supplied from a small steam-driven dynamo and conveyed to the vehicle by means of a metal bar mounted on posts along the side of the track.
On the completion of a water power station the line was formally opened by the Lord Lieutenant of Ireland on 28 September 1883.
On 3 August 1883, Magnus Volk opened his small railway along the beach at Brighton, power being supplied from a shunt-wound dynamo, driven by a 3 h.p. gas engine, to a series-wound motor on the small passenger car. Several other small electrical railways were laid down in this Country in succeeding years, but it was not until 1890 that a standard gauge railway, fully equipped with stations and signals and with locomotive hauled trains, capable of handling large numbers of passengers was established. This was when the City and South London Railway was opened from Stockwell to King William Street in the City of London.
In 1893 the Liverpool Overhead Railway opened and in 1898 the Waterloo and City Railway followed by the Central London Railway in 1900. Tables were then shown in which particulars of the various eleclrified lines in this Country were given, including descriptions of the types of rolling-stock in use, horse-power of motors, system of control equipment, etc.
Among his concluding remarks this speaker said that while the main purpose of this symposium was to illustrate the present position of electric traction in this Country and indicate the generall trend in rolling stock design and equipment, it might he permissible to mention certain advantages from electrification. Electrification is, of course, economically justifiable on lines where existing traffic is heavy, or there is reason to expect considerable traffic increase from a faster and more frequent service.
For trains working through long tunnels and over very heavy grades, electrification has proved to be most successful.
Electric locomotives can be constructed with a large proportion of axles motored to secure a high tractive effort, or several locomotives may be coupled together and operated by one train crew. The maintenance and operating costs of electric rolling stock engaged in really intensive service is substantially lower than with other forms of railway traction.
The second section, referring to Power Supply for Railways, was presented by W.G. Thompson, Ph.D., B.Sc., A.M.LE.E., who, dealing with the matter of supply and distribution, said electrical energy for traction purposes has to be supplied in a suitable form with the maximum reliability and minimum cost. Unfortunately, the form of electrical energy used for traction in this Country is not the most suitable for transmission requirements, hence the need for converting equipment. Usually three-phase extra high tension alternating current lines transmit power at voltages of 11,000 volts or upwards from the generating station to the track sub-station, where the supply is transformed down, converted to direct current and supplied to the track at, say, 3,000, 1,500 or 600 volts D.C.
To-day most of the converting equipment is of the mercury arc rectifier type, although there is still a number of rotary converter plants in operation. The size and arrangement of the equipment will depend upon the power demand and the overload requirements dictated by traffic conditions. Sub-station capacities up to 8,000 KW. may be required, but individual rectifier units are unlikely to exceed 3,000 KW. or 4,000 hp.
Reliability of electrical equipment is achieved in several different ways, the chief of these being the inherent self-protection of the selected equipment, the provision of the necessary additional protective gear, the duplication or sectionalising of essential circuits and the carrying out of regular maintenance inspection.
Minimum costs are attained by adjusting the balance between capital expenditure and supply losses and through the incorporation of labour-saving automatic control, whereby the majority of sub-stations are unattended and are operated from a central control room.
A diagrammatic layout of mercury arc rectifier equipment was shown and the arrangement of the components-intended to provide both safety and flexibility in operation-described.
The thlrd section was on Electric Traction Motors and was given by J.W. Voelcker, B.Sc., A.M.LE.E., who commenced by describing the characteristics of motors. It was mentioned that the fact that these can be designed to give adequate power within the physical limitations of wheel pairs of almost any gauge and axle load enables the motive power to be distributed over a number of vehicles, thus demonstrating one of the outstanding features of electric traction. The principal characteristics of a motor are torque and speed and are usually expressed in terms of tractive effort at the driving wheel and vehicle speed respectively, both to a current base at average line voltage. The general nature of their relation is a matter of design, while by suitable selection of gear ratios and wheel diameters the desired vehicle performance may be obtained. Moreover, the choice of gear ratios for a given gear centre dimension has an important advantage when applied to electric traction, for it often permits the same motor and control equipment to be used in both passenger and freight service, the gear ratio alone being altered, thus enabling a valuable degree of standardisation and economy in spares to be obtained.
On the subject of speed control the contributor of this section said that the speed of a motor can be controlled by variation of either applied voltage or of its feld excitation. In traction work with constant supply pressure the former method can only be applied to a reduction of voltage by the wasteful insertion of resistance, as at starting. Field weakening, on the other hand, permits a series of increased speeds to be obtained economically though accompanied by a reduction of tractive effort.
The excitation may be varied either by making tappings in the field windings, or by shunting the field with suitable resistances. The subjects of rating, power-weight ratio, mechanical details, etc., were all referred to under this heading.
Lastly came the section devoted to Control Equipments, which was contributed by J. H. Cansdale, M.LE.E., who described the methods of control in use.
Generally speaking, in this Country, electric locomotives have not, up to the present, been used for railway work, though a very important section of the L.N.E.R., the Manchester-Sheffield line, is now being electrified and will employ 70 locomotives. The Southern Railway is also building two electric locomotives for trial running. Details of these being not yet available, consideration was confined entirely to multiple unit stock. There are, in general, two types of control. electra-magnetic and electro-pneumatic, both of which may again be sub-divided into unit contactor and camshaft types.
Brief particulars of the different types were then given, together with a schematic diagram showmg the method of resistance notching of .the P.C.M. control. This contral is installed on the London Transport 1938 tube stock and is new to this country although it has been operating satisfactonly in the U.S.A. for a number of years. A reference to the Metadyne control concluded this comprehensive and interesting paper.

Irish notes. 149-50. 3 illustrations
"In view of the probable closing down of the remaining narrow gauge systems in Ireland..." Considers narriow gauge operatted by Northern Counties Committee and refers back to article in Locomotive, 1902, 7, 92 noting that most of the locomotive types described then had disappeared. The 3 ft. gauge lines of the Northern Counties Committee (L.M.S.R.) comprised the lines from Ballymena to Larne, with branch from Ballyboley to Doagh, Ballymena to Retreat, Ballymoney to Ballycastle and Londonderry (Victoria Road) to Strabane. The Ballymena and Larne Iine is now only in use for goods traffic, while the same remark applies to the section from Ballymena to Retreat; the last portion of this line, from Rathkenny to Retreat, was closed to all traffic on 19 April 1937. The section from Ballymoney to Ballycastle was, until 1926, an independent company; passenger traffic was still operated on this line. The last section from Derry to Strabane was worked by the County Donegal Rlys. Joint Committee, who provided the rollmg stock.
A class of six 2-4-2 compound side tanks was built as follows: Nos. 101 and 102 (formerly os. 113 and 112) by the N.C.C. in 1908/9; Nos. 103 and 104 by the N.C.C. in 1919/20, and Nos. 110 and 111 (formerly Nos. 69 and 70) by Beyer, Peacock & Co. in 1892. The original dimensions were: cylinders 14¾ in. and 21 in. by 20 in.; coupled wheels 3 ft. 9 in. and wheelbase coupled 6 ft. 3 in., total 20 ft. 3 in. Heating surface, tubes' 677.86, firebox 63.03, total 740.89 ft2, grate area 11.29 ft2., tanks 570 gals., weight in working order 30 tons, of which 20 tons was adhesive. The classification was S, but only Nos. 104 and 111 were still running in this state, No. 103 had been scrapped in December 1938.
Nos. 101 and 102 were rebuilt as class S1 in 1933, the wheelbase being lengthened 2 ft. 0 in. in the rear to provide a larger bunker; the weight in working order being 32 tons 18 cwt. These two engines worked the Ballycastle section.
No. 110 was rebuilt in 1931 as class S2; in this case a four-wheeled bogie was substituted in the rear, the wheel arrangement of 2-4-4 being probably unique in the British Isles; a larger boiler of G6s type was also provided; it measured 9 ft. 10ft in. by 4 ft. 0 in., and the centre is 6 ft. 1 in. above rail level. 164 tubes of 1¾ in. provided a heating surface of 825 ft2., which with 83ft2. added by the firebox bring up the total to 908 ft2. The pressure was 200 psi., the grate area 12 ft2, and the weight in working order 44 tons 4 cwt. This engine was still at work on the Ballymena and Lame section. Two 4-4-2 side tank engines were taken over from the Ballycastle Rly. in 1926, which had been built for that line by Kitson'in 1909; the cylinders were 14½in. by 22 in., wheels 3 ft. 7 in. and 2 ft. 6 in., wheelbase coupled 6 f.t. 6 in., total 22 ft. 5 in.; boiler 9 ft. 6 in. by 4 ft. 0 in. with 170 tubes of 1 ¾ in. Heating surface, 769 (tubes) plus 83 (firebox), total 852 ft
2., grate area 12 ft2., tanks 800 gals., weight in working order, 39 tons 11 cwt. They had proved too heavy for the Ballycastle road, so they were adapted by their new owners to work on the Ballymena and Lame section; the top of the funnel was reduced from 10ft. l0in. to 10ft. 2½ in., the coupled centres were reduced from 2 ft. 3 in. to 2 ft. 0 in., and a new boiler 9 ft. 10 in. by 3 ft. l0½ in. fitted; they were numbered 113/4 and classed T, and were still at work bringing up the narrow gauge total to seven locomotives.

The Turkish State Railway placed orders for fifty eight locomotives with English builders. The firms to be entrusted with the construction of these engines are Beyer, Peacock and Co. Ltd., the Vu1can Foundry Ltd., and Robert Stephcnson and Hawthorns Ltd.

Metre gauge Beyer-Garratt locomotives Abidian-Niger Railway. 150
Acquired ten 4-8-2 + 2-8-4 Beyer Garratt articulated locomotives for working the heavy traffic. The main line is about 500 miles long between Port Bonet-Abidjan and Bobo Dionlasso, and has many steep gradients and sharp curves; the maximum gradient being 1 in 40 and the minimum curve 460 feet radius. Rails 50 to 60 lb. per yard. The total weight of each engine in working order was 148 tons and the total length over buffers was 90 feet 5 inches. The maximum axle load is lit tons and the tractive effort at 85 per cent. b.p. is 44,660 lb. Other particulars are as follows:- cylinders (4), 17 in. by 24 in ; coupled wheels 4 ft. 3 in. diameter. heating surface:-tubes, 1,805 ft2.; firebox, 186 ft2; superheater, 258 ft2. Total, 2,249 ft2 grate area, 47 ft2. Boiler pressure, 200 psi. The Walschaerts gear is operated by a steam motor placed in the boiler cradle manipulated from the cab by a hand lever. Shaftings run from the motor to each set of valve gear, crossing the articulation gap by special universal joints. Each rod has a worm actuating a block to which the lever operating the radius rod is attached. Check sectors at the valve gear and an indicator in the cab are provided.
The tanks carry 6,160 gallons of water. The fuel is usually wood (hard) but a proportion of coal is necessary for obtaining the higher speeds of 45 m.p.h. with a 750 ton train on the level. The engines were built at Raismes, France, by the Societe-Franco-Belge in collaboration with Beyer, Peacock & Co. Ltd. Manchester. Tests with these locomotives have been so successful that a repeat order for ten more had been placed with the same firm.

Tender locomotives
GWR. Twelve new Manor class mixed traffic 4-6-0; additions to Castle and Grange 4-6-0 classes and 4-4-0 Earls were under construction. Ten n ew standard goods 0-6-0 brought up the class size to fifty; and after a long gap more 2-8-0 coal engines were under construction.
LNER. New construction: ten Pacifics, 19 Green Arrows, 5 Lochs and 37 standard goods 0-6-0s and NBR Atlantic restored to traffic
LMS: Ten new Pacifics to an enlarged design; twenty standard mixed traffic (4-6-0) and two 2-8-0 coal engines were added to stock.
S.R. A new class of goods engine (Class Q 0-6-0) was introduced, eleven of an order for 20 being completed.
Tank engines added:
GWR. The 72XX class of 2-8-2T was increased to a total of forty engines (conversions from 2-8-0T) whilst three varieties of 2-6-2T were turned out and 35 standard 0-6-0 pannier shunting tanks.
LNER. Fifteen standard passenger tanks V.1 and five standard goods tanks J.50 were the only additions. It is worth noting that the goods tanks were built at Gorton; new engines have not been built here for many years with the exception of two special tank engines of a modified G.C. design.
LMS. Sixty passenger tank engines were put into traffic, Nos. 2618-2651 of the 2-6-4 type and Nos. 173-184 and 196-209 of the smaller 2-6-2 variety.
S.R. The only addition was No. 1302, transferred to ordinary stock (previously "service vehicle" No. 234S, and originally S.E.R. No. 302).
Engines withdrawn. "It is not practicable" to give these in detail, but it may be mentioned that on the G.W.R. the M. & S.W.J. 0-6-0 and 4-4-0 tender engines had now disappeared from the list as well as several Dukes and Bulldogs and Dean goods. Many of the engines withdrawn, were being renewed as new standard types as already recorded in these pages:
On the LNER. the B13 (Paris Exhibition) class 4-6-0 had become extinct, also some H. & B. and N.B. classes of 0-6-0 goods engines. Two classes of tank engine had also disappeared, the North Eastern 2-4-2T and the Great Eastern 0-4-4T as well as other numerically small classes. On the LMS, as regards tender engines the L. & Y. types had been the heaviest sufferers and three of the L. & Y. Baltic tanks had also gone. The Caledonian 4-4-0T and the Midland 0-6-4T were both extinct. Nineteen of the L. & Y. 2-4-2T had disappeared, but quite a number of this class still remain in traffic. On the S.R., Drummond's first 4-4-0 class had now disappeared, No. 298 having been the last survivor. Three Adams' 0-4-2 Jubilees and four Stroudley 0-4-2T were other noteworthy withdrawals.
The scrapping programme has not been so heavy during 1938 as in 1937; of 11,909 tender erigines 234 were cut up, and of 7,770 tank engines 186 were withdrawn. Readers who wish to make further comparisons should turn up Locomotive Stock Returns 1937 on page 131 of our 1938 volume.

Old third class carriage District Railway, London. 154. illustration
Photograph taken outside the Gloucester Carnage and Wagon Company's Works and shows an example of a carriage built (about 1874) by them for the District Railway, London. It will be noticed that the vehicle had the familiar round topped doors characteristic of the Metropolitan and the Metropolitan District, or as it was called, "The Daylight Route." The carriage was fitted with the continuous vacuum brake, and more interesting, had arrangements for lighting by coal gas carried in a longitudinal flexible reservoir of india rubber sheet concealed in the box like structure on the roof. The gas was filled through pipes brought down to platform level to connections which could be coupled up to the gas mains at the terminal stations.
The guard had no special compartment but travelled in the last one of each train, this being provided with observation windows to the rear, and a large gas tail lamp. Carriages composing the trains were first, second and third class.

Private carriages on railway trucks. (From a Correspondent).. 154
The custom of travelling .in one's own carriage in the early days of railway operation is mentioned by Charles Dickens in Dombey and Son. The eccentric Duke of Portland usually travelled in this way between Welbeck and London. His last journey was performed in this manner, the private road carriage being mounted on a M.S. & L.R. carriage truck. A serious accident on 8 December 1847, probably conduced to the abolition of this means of travel, for it became obsolete soon after 1850.
On the day mentioned the "up" Leeds to London express was approaching Rugby when a private carriage in which the Countess of Zetland was travelling with her maid was set on fire by a spark from the locomotive. The "umbrella," or hood, caught first, then the carriage. The two women were obliged to evacuate the body of the vehicle and clung to its wheels while the train rushed along, despite efforts of other passengers to attract the attention of the driver. Before the. train could be stopped the maid fell off on to the track and was killed, whilst the Countess was badly burned and rendered insensible. She was ill at Rugby for some days afterwards in a critical condition.

The theory of machines. Thomas Bevan, London: Longmans, Green and Co. Ltd. 549 pp., 357 fig.
Intended principally for students preparing for an. engineeriing degree or for an associate membership exaninattlon of one of the technical institutions, this book contains a good deal of information useful to the practising engineer whose theoretical knowledge has become rusty, or who has to make a study from first principles of some phase of mechanical engineering outside his normal orbit. To the locomotive engineer the chapters on valve diagrams and gears and balancing will attract .the first attention, but unfortunately these two chapters are none too long for the ground they have to cover. In the former, such out of date and rarely used motions as the Joy, Gooch, Hackworth, and Marshall are illustrated and described, but .it would have been far more valuable to have concentrated on the Stephenson and Walschaert [sic] types and to have left out the others. There is still a real need for competent and conoise instructions as to the working out of the proportions and characteristics of these two—so far and away the most widely-used of all locomotive valve gears. High commendation is due to the author for having adopted Dalby's graphical method for the balancing of masses revolving in different planes. It gives quickly, simply and aocurately all that is required in locomotive calculations, and there seems to be not the slightest reason for the perpetuatron of clumsier methods. But it is probably dangerous of the author to say that at high speeds the effects of unbalanced forces may lift the wheel from the rail. The speed at which this occurs is probably universally above what the particular engine could attain. For example, uhe three-cylinder 4-8-0 engines with 55½-in. wheels belonging to the B.A. Great Southern Railway, which have proportions suspiciously like those of the author's question 23 on p. 481, have a critical speed of about 110 m.p.h., but if the balance weights for the reciprocating weights had been concentrated in the driving wheels, which may have been what the author had in mind, instead of being spread over the six coupled wheels as is normal praotice, the critical speed would have been lowered to 63-65 m.p.h. Among the remaining 23 chapters in this well-written and well-produced book is included material on brakes, gearing, governors, and vibrations, in addition to elemental chapters on friction, inertia and kinematics, and one of the most interesting subjects touched upon is coriolis acceleration, which is rarely covered in any text book, the normal author apparently being scared of the complications of determining the acceleration of a sliding point relative to another fixed point on the same moving link.

The Taff Vale Railway. D.S. Barrie. The Oakwood Press.
The Oakwood Press are doing good service in publishing short histories of some of the many railways which have recently been absorbed 'in the four groups and are likely inl consequence to become forgotten. No. 2 of the series, dealing with the Taff Vale Railway, has just been issued, and as it is from the pen of D.S. Barrie there is no need to stress the care and accuracy with which it has been produced. Of the many independent lines serving South Wales, the Taff Vale was not only the oldest and most important, but is historically interesting in that the upper part of its main line is the modern equivalent of the Penydarran tramroad, the first line to be traversed by a steam locomotive. Its system of lines was somewhat intricate and perhaps not easily followed by those not well acquainted with the district, but the author has been at great pains to make this clear both in the text and in the diagrams accompanying it. The development of the system is traced from the beginning and the multitude of dates given bears testimony to the amount of research bestowed on it. The principal types of locomotive are described, half a dozen of them being illustrated by half tone blocks, whilst portraits are also included of such Taff Vale stalwarts as Ammon Beasley and Tom Hurry Riches. The next volume of the series will be looked forward to with interest.

The locomotive stock book, 1939. D.R. Roberts, C. Smith, D.E. White and K.R. Prentice. London: Railway Correspondence and Travel Society.
This publication comes out in full once more this year, and contains in its fifty-four pages a considerable mass of statistical matter. Compared with the issue for 1937, all the former features are retained, with the addition of a list of locomotives ,preserved in various places and those of many minor lines which appear for the first time. For the four main groups complete lists are given of all the locomotives in stock at the end of 1938, together with up-to-date tables of all named engines, and particulars of those added and withdrawn during the year. Illustrations are given of those classes which became extinct, whilst ·the representations of name and number plates introduced in 1937 have this year been added to with a completely new set which also includes certain transfer coats of arms used by some of the railways. This is a very interesting feature which, it may be hoped, will be further extended in future issues.

Train speeds and services in 1938. Lionel Wiener. Brussels: The International Railway Congress Association.
Abstracted from the Bulletin of the International Railway Congress, the particulars reproduced in this booklet form a comprehensive analysis of all the fast train timings in Europe. In addition to the statistical tables giving the longest and fastest runs in each country, distinguishing between those made by steam, diesel and electric traction, a number of useful diagrams are inserted showing the routes taken by the trains dealt with. The author's name is sufficient guarantee of the care taken to secure accuracy, but it seems a pity that more care was not taken in checking the proofs. This would undoubtedly have avoided such anomalies as crediting (Table 17) runs between Paris-St. Quentin and Paris-Troyes to the L.M.S.R., or the discrepancies in the distance between Euston and Carlisle , 467 km. in Table 13 and 481 km. in Table 18; the lattcr is correct.

Narrow gauge locomotives. R.W. Kidner. The Oakwood Press.
In our January issue we reviewed a booklet British Light Railways by the same author, and the present work supplements the particulars given in the former publication. It contains principally tables of dimensions, these were not given in the previous volume, and also reproduces many of the engine sketches which were. Some new half tone blocks, however, have been included which add to its usefulness. There is also a list of former locomotives on narrow gauge railways which have now been withdrawn.

Locomotive design. P.A. Hyde.
Re issue of 15 April, letter from J.G.B. Sams, in which he asks if the popularity of roller bearings for locomotives exists outside Sweden. From this it would appear that . Sams is lacking information on the subject and it might interest him to have certain facts which point to the steadily growing adoption of that for m of bearing, at least in the United States and in the British Commonwealth.
As a matter of fact, Sweden is behind other countries in the adoption of the roller bearing for locomotives. Not very long ago I was shown a statement issued by the A.R.A. which stated that over 60 per cent. of the engines then under construction in the States were roller equipped, and a reference to the descriptions of engines lately built shows that a very large proportion are equipped on all axles with one or other of the outstanding makes of bearing. I think I am right in saying that all the Diesel electric passenger trains and vehicles are so equipped. Sams may be interested to learn that of the locomotives lately delivered from the UK or on order here a high proportion are partly or fully equipped with roller bearings, while two systems within the British Commonwealth, viz., the South African Railways and the New Zealand Government Railways, seem to be standardising the roller, the former for all carrying axles of engine and tender and the latter for all axles.
Within the last three or four vears South Africa will have had more than 300 engines so fitted, while New Zealand have now more than 50 engines under construction here and have placed orders for some 20 further sets of bearings. Within the last few months the papers have noted that 16 Garratt's with rollers on carrying axles have been shipped to South Africa and it is within my knowledge that a further 9 similarly equipped are being built for other systems. Two engines of normal design were lately shipped to India with rollers on bogies and tender and I believe that I am right in saying that a further 20 are so building at the moment for that country.
As far afield as Manchuria completely rollerised engines are in service, and I think that Sams can agree that the above facts point 'In the "long way" as having been covered and he need have no regrets on the subject.

Locos. of the Appleby-Frodingham Steel Co. R.A. Wheeler. 158
With reference to the interesting serial article now appearing in the Locomotive on the subject of the Locomotives of the Appleby-Frodingham Steel Co., it is of interest to note some further details regarding engine No. 9 which I obtained some time ago from the Yorkshire Engine Company. This locomotive was built by the Yorkshire Engine Co. in January 1902-Makers' No. 628-and had cylinders 14 in. by 20 in. and wheels 3 ft. 3 in. in diameter. It was purchased about 1917 by the Redbourn Hill Iron and Coal Co. Ltd.

Floodlighting a railway depot. 158
New system of floodlighting installed at Nairobi Station and Goods Yard, the main centre of the Kenya-Uganda Railways. Increase of traffic at this point, where most of the work is carried out at night, necessitated some improvement of the former lighting system. A new floodlighting scheme supplied by the General Electric Co. Ltd. was carried out by the mechanical engineer's department of the railway. The installation consists of twenty G,E.C. Broadway-type floodlights mounted on steel poles. Six of these poles are equipped with two units each and eight have one each. Fourteen of the lamps are of 1,000 watt capacity and six of 500 wntt.
The total area illuminated is about 75,000 sq. yards. The standards were carefully positioned so that all lines and points were brilliantly lit up. Ground signal lights arc no longer necessary for indicating the position of the points; these can be seen by engine drivers from a considerable distance. Each lamp is provided with a focussing device and also with "sights" similar to those on a rifle. These enable the lamps to be correctly focussed so that the beam is thrown in the desired direction.

Stone-Deuta electric speed indicator for locomotives. 158
J. Stone arid Co. Ltd., booklet describing the new Stone-Deuta electric speed indicator for locomotives. This device is easily installed on locomotives or railcars and its makers claim, among other advantages over mechanical systems, that its accuracy is not affected by wear and little artent ion is required. A useful feature of this instrument is that it can be cal ibr a ted to suit any size of driving wheel within the range of 4 ft. to 6 fit. 9 in. diameter. The above named company have also sent us a book on the Isothermos axlebox. With the increase of speeds and journal loadings which have taken place in recent years it has been necessary to evolve a box which will withstand modern condlitions. The axlebox in question has been brought out after much study, and the fact that stock fitted with it is stated to run some 80,000 miles without the axleboxes receiving any attention

The annual Continental outing arranged under the auspices of the Mutual Improvement Class at Norwood Junction Locomotive Depot took place from Friday 19 May to 23 Tuesday 1939. Holland was selected for attention. Visits were made to the Locomo-tive Depots at Amsterdam (Central) and Rietlanden, on both of which the party was accompanied by L. Derens. One whole day was devoted to a round-trip of Holland by rail, the itinerary selected involving passage over the great bridges spanning the Lek, Waal, Linge, Maas, and Hollandsch Diep. A halt was made en route at Utrecht to visit the Railway Museum, where the party was received by Asselberghs, the Curator ; this aroused the greatest interest, and the demonstration of the signalling system in use on the Netherlands Railways by means of the model track on exhibition was highly appreciated, as it enabled the principles of operation to be acquired in the minimum of time. The visitors were subsequently entertained to luncheon at the Hotel Terminus by the Conductor, J. Pelham Maitland, at which Baron van Pallandt van Eerde and G. J. de Vos van Nederveen Cappel were also present. An excursion was also made to Volendam and Marken, in the Zuyder Zee, and around the city of Amsterdam, by water, in a private launch specially chartered for the party.

First  locomotive to which balancing was applied was Sandusky buil for the New Jersy Railroad and Transportation Co. by Rogers, Ketchum & Grosvenor. .It seems that Rogers gained the idea from baldwin who had built Ironsides for the Philadelphia, Germantown & Norristown in  1832. Baldwin took out a patent for a cast iron wheel in 1833 and tese were fitted to E. Miller. on the Charlestown & Hamburg R.R. 
These compound wheels were more successful than anything previously tried, and continued to be used for several years. Many years later there were some lines having a gauge of 5 feet which it was apparant must soon be converted to standard gauge. To avoid exten- sive alterations to wheels and axles when the time for conversion came, Rogers in 1881 introduced a wheel centre having a wide rim, a projection pp being cast on the inside of the wheel centre. When the engines were new the tyres were set on the out- side, Fig. 5. When gauge alteration became necessary they were pressed further on and the portion of the wheel centre left projecting on the outside then turned off.

Wheels of this type were first used on an engine for the Alabama & Great Southern R.R: in 1881, and thereafter all 5 feet gauge engines built by Rogers were fitted with them.

The railway section of the Swiss National Exhibition held in Zurich, and open until 29 October 1939, was divided iinto outdoor and indoor exhibits, and compared with the last of these exhibitions to be held in Zurich, that of 1883, was a complete change-over, for whereas the piece de resistance half a century ago was the then new 4-6-0 steam locomotive class built for the Gotthard line, steam at the 1939 show was relegated to two old machines, both of which were running before the 1883 exhibition, and a snow-plough. However, the Gotthard line was again very much in evidence.
First of the two steam locomotives was the Speiser, an 0-4-4 Engerth tank engine built in 1857 by the Maschinenfabrik Esslingen for the Swiss Central Railway, and rebuilt at the Hauptwerkstatte Olten in 1880. It has inside cylinders and outside pipes leading from a steam stand and regulator just behind the chimney to the valves beneath the smokebox. The second steam engine is the original four-wheeled Riggenbach rack locomotive of the Rigi Railway. It has a vertical boiler and 'outside cylinders, and bears the Swiss Locomotive and Machine Works No. 1, date 1873.
The rotary snow-plough is one of those used on the metre-gauge Rhaetian and Bernina Railways. It is of the 0-6-6-0 type, WIth a four-wheeled tender, and the mechanism is driven by two sets of outside cylinders having valves controlled by Walschaert motion .. Steam is used only for the knives and for runnmg light ; when in operation in a drift the plough is pushed by one or more electric locomotives. A snow cutter belonging to the Bernina Railway was also on show.
Largest of all the exhibits was the 244-ton 12,000 h.p. electric locomotive for operatmg passenger and freight trams over the sinuous 1 m 38-40 grades on the Gotthard (Lucerne-Chiasso) route of the Swiss Federal Railways. Normally it had a starting tractive effort of 110,000 lb. and. an adhesion weight of 160 tons, but the electncal equipment can produce a starting effort of no less than 140000 lb. and can maintain it up to nearly 40 m.p.h. when this is to be used ompressed-air weight-transferring cylinders are brought into operation, and transfer some a! the weight from the carrying axles on to the driving axles. Even so, against this maximum load of 172 .tons .on the driving wheels the factor of adhesion was only 2.75, and a special wheel-slip indicator was provided in the driving cabin to assist the dnver in maintaining adequate control. The tractive effort at the one-hour rating of the electrical equipment was 88,000 lb. at 45 m.p.h. Express passenger trains of 600 tons weight are hauled up the 1 in 38-40 grades at 40 m.p.h. and 750-ton freight trains at 31 m.p.h.; the top speed is 68 m.p.h. A glass side panel is fitted down one side so that he motors and part of the control and ventilat- ng apparatus can be seen, but the layout of most ,f the main equipment can be observed from the entral passage down the cab.
Cheek by jowl with this 28-wheel machine wsa a double-bogie diesel-electric locomotive of just one-tenth the power, built for hauling light fast assenger trains over the non-electrified lines in le north of Switzerland. It is powered by an eight-cylinder 1,200 b.h. p. Sulzer oil engine running at 750 r.p.m. and equipped with a Buchi isupercharger; this engine was coupled to a 700-kw main generator which supplied current to four nose-suspended traction motors. The locomotive weight is 65 tons and the top speed 68 m.p.h. A special single-phase generator is inserted between le main and auxiliary generators, so that the locomotive can supply standard 16. 6-cycle electric eating current to the carriages in the train, all of which are fitted for the single-phase type of heating of the electrified lines.
The Bern-Lotschberg-Simplon Railway (or Blerner Alpenbahn Gesellschaft) showed one of its new I-Co + Co-l express electric locomotives with Secheron electrical equipment and individual axle Jive, but bearing the Swiss Locomotive and lachine Works number 3678 (1939). It can Ivelop a maximum output of 6,000 h.p. The siss Federal Railways have developed their well- mown Red Arrow single-unit single-phase fast :ectric motor-coach into a twin-car non-articula- ' ~ unit with a buffet and with 126 second class md third class seats. The construction is mainly hluminium. Another twin-car motor-coach set the articulated vehicle with Liechty guided Wes which hauls trailers over the Bern-Neuchatel le; it has 18 second class and 115 third class ts, a postal compartment and a baggage room a tare weight of 68 tons; it is allowed a top d of 68 m.p.h. against the 81 m.p.h. of the Red Arrow set.
Among the carriage stock is a special observa- n trailer, with glass round the ends and sides with a partial glass roof, for use on the metre-gauge Brunig section of the Federal Railways, running from Lucerne to Meiringen and Inter- laken. Built by the Schweizerische Industrie Gesellschaft, of Neuhausen, it contains 28 mov- able arm-chairs and a baggage compartment on a tare weight of 16 tons. It has the Brown Boveri form of lighting dynamo drive through bevels and a cardan shaft from the end of one of the axles. A new 37-ton all-steel standard- gauge postal sorting van of the Swiss Federal Railways is another exhibit built by the same firm. It has 9 ft. 10 in. bogies pitched at 53 ft. 9 in. centres and is equipped with Westinghouse automatic and non-automatic brakes.
Under cover, the exhibits generally are of a smaller character, but include a full-size under- frame and wheels of a four-wheel freight van fitted out with a complete set of Westinghouse automatic brake gear, and with an explanation of its operation There is a large working model of freight and passenger trains at four periods of Swiss railway history, each train of a weight and running at a relative speed corresponding to its period. Other models are those of the Wiesinger high-speed train, which, it is claimed, could maintain a speed of 225 m.p.h. on its own special track and run to a schedule of 50 min. for the 179-mile journey from Zurich to Geneva, and of the new Rhaetian Railway 34½-ton 600 h.p. motor-coaches of normal design, several of which are now under construction.

Nos. 8119-22 were the latest 2-8-0 freight tender engines (Class 8F') to be turned out at Crewe. Four others. completing the order, would shortly be in traffic. The first of a new series of 4-6-2 Princess Coronation class locomotives—all of which were to be streamlined— also nearing completion at Crewe. It is understood that alI the engines in this and the subsequent series are to be named after Cities served directly by the L.M.S. At Derby some further Class 4 0-6-0 freight engines had been completed, the latest in service being No. 4581. After being "run in," these engines are transferred to stations on the Midland Division. Royal Scot class 4-6-0 No. 6144 has been named Honourable Artillery Company. Recent withdrawals included two further ex-L.N.W. engines: 0-6-2 coal side tank. No. 7751 and 0-6-0 saddle tank No. 27469, originally one of Webb's 0-6-0 coal engines.

No. 15 was acquired from Andrew Barclay in 1907. It was intended for hauling material from the crusher chutes to the high level furnace bunkers and for taking slag to the tip. In 1915 it fell from the top of the slag tip and required rebuilding. No. 16 was purchased from Peckett & Sons and intended for haulage of ironstone from the Conesby mine and after 1910 from the Thealby mine partly over the North Lindsey Light Railway and following WW1 was used within the works mainly on short hauls up steep gradients. No. 18 was obtained from Hudswell, Clarke & Co. in 1910 and was used on ironstone haulage. It was renumbered 19 in 1938.

Notes on Fell's inventions. 183. illustration
John Barraclough Fell was born in 1815 and spent the early part of his life with parents in London, removing with them some twenty years later to the Lake district. Here, in the 1840's, he carried out his first railway work in connection with the Furness and Whitehaven Railway. Much of Fell's work is well known and has received adequate recognition in the technical press, but there are some of his activities less known and it is these which it is proposed to mention here. In 1852 he went to Italy where for some years he, was associated with Brassey and others in the construction of several of the early Italian railways. Among these lines, which were constructed by the firm of Brassey, Jackson, Fell and ]opling, were the Central of Italy, the Maremma and the Genoa and Voltre Frequently traversing the mountains by road led him to give his attention to mountain railways, with the result that he evolved the Fell Centre-Rail system for extra adhesion. This scheme was patented in 1863. In the years 1864-55 he carried out experiments on the Gothland indine of the High Peak Railway in Derbyshire which resulted in the subsequent adoption of the system to the crossing of the Mont Cenis Pass of the Alps between St. Michel in France and Susa in Italy. This was the first Alpine Railway and carried the International traffic between Italy and France, as well as the Indian mail, prior to the opening of the tunnel. Fell's inventive ability was by no means confined to devising ways of working steep inclines, for he also devised a single-line suspended railway, operated by a wire rope which was erected between the Parkhouse Hematite Ore Mines, near Furness Abbey, and Roose Station on the Furness Railway. This was later replaced by a line of 8 inches gauge, but certain practical troubles occurred in operation and Fell determined to adopt a rather wider gauge, 18 inches being decided on. The Board of Trade became interested in this project, and as a result the Government constructed an experimental line during 1873-74 at South Camp, Aldershot, to provide transport between various stores. The rails were laid upon a continuous wooden structure formed of parallel beams supported at regular intervals by wooden pillars which were suitably braced with transverse struts. The rails were four in number, two being fitted on the upper faces of the beams and two on their outer faces; the sur face rails were of iron while those at the sides were of wood and contacted with the horizontal wheels of the rolling stock. The tender locomotive illustrated was designed and constructed by Manning, Wardle & Co. of Leeds; the cylinders were 6t in. diameter by 10 in. stroke. The six flangeless wheels carrying the engine were 16 in. diameter: the wheelbase being 10 ft. 8 in. The boiler was of interest at the time in that it was welded and flanged, angle-iron being dispensed with in its construction. A copper firebox was fitted having a heating surface of only 14 sq. ft., while the grate area was but 3 sq. ft.: the tubes, of brass, were 22 in number, with an external diam. of 1 kin., giving- a heating surface of 62 sq. ft. The boiler was fed by two injectors. Dimensions of the engine were: length 13 ft. 2t in., width 5 ft. 1 in., the weight in working order being 4 tons 8t cwt. The tender, which was also carried on wheels of 16 in. diameter, had a water capacity of 172 gallons and space for 15 cubic feet of fuel. The length of the engine and tender was 25 ft. 4 in. and their total gross weight 8 tons 4 cwt., distributed over a total wheelbase of 22 ft. 5 in. Although the trials passed off favourably the line was-in the words of Sir Arthur Heywood, an acknowledged authority on narrow gauge railways-"a sad failure."
Fell was fond of relating that he was respon- sible, among other achievements, for placing the first steamer on the English lakes, this appearing on Windermere in 1851; that he constructed the first railway in the Papal States of Italy, and that he carried the first railway over the Alps. In both his centre-rail system and his light railway work he was assisted by his son G. Noble Fell. J. B. Fell died at his residence in Southport aged 87 oo 18 October 1902.

Crewe Suspension Bridge. 183
"The Spider" bridge, which had been for many years a familiar landmark to travellers over the West Coast Route was to be demolished. It was built in 1878 to convey stores to and from the station, and was 720 feet long. It crossed the network of lines just north of the station and at one time it carried a narrow gauge track on which the srnail steam locomotives Tiny and Midge used to work.

Tore Westerman. The Lapland Ore Railway. 184. 2 illustrations
Northern of Europe Railway Co., an Anglo-Scandinavian concern, obtained in 1882 a concession to build a railway from Lulea on the Gulf of Bothnia, to Gallivare, 42 miles north of the Arctic Circle, a wild, barren, and nearly uninhabited province. The object of a. railway over this cold Arctic region was to serve the rich iron ore deposits at Gallivare and Kirunavare and bring it down for shipment from the port of Lulea. In 1886 the concession passed on to the Swedish and Norwegian Railway Co., in which Dutch interests dominated. The first ore train ran through to Lulea on March 12, 1888.
The Swedish and Norwegian Rly. Co. had eight locomotives in service-six 0-4-0 saddle- tanks and two 0-8-0 tender engines. The saddle- tanks were built by Black, Hawthorno. be- tween 1884-1887. Their leading dimensions were: cylinders 13 in. by 19 in., driving wheels 3 ft. 6 in. diam., weight in working order 23 tons 9 cwt. These engines, together with the whole railway system, were taken over by the State Railways in 1891. The saddle tanks were known as the "Qa" class and numbered 442 to 447 —two of these were in service at Stadsgarden—the port of Stockholm, but all are now scrapped.
Twenty 0-8-0 goods locomotives were built by Sharp, Stewart and Co. for the Swedish and Norwegian Rly. Co. between 1886 and 1888. Eighteen of these engines were never delivered, as the railway company went into liquidation. The two engines delivered worked the ore trains when the railway was taken over by the State in 1891. They were soon withdrawn from service, being too heavy for the rails, which were of a very light type. These engines stood idle from 1891 to 1897 in the yard of Lulea. They were sold to the Baden State Railways in 1897, and after being in service for a short time were transferred to the Barry Railway, S. Wales. Already this Co. had bought two of the engines of the same type which the Swedish and Norwegian RIy. Co. was unable to take from the builders. These 0-8-0s were very powerful for these early days and they were the first 0-8-0 tender engines to work on a British railway. These four engines—later G.W.R. Nos. 1387-1890—were withdrawn from service between 1927 and 1930. Their main dimensions were: cylinders 20 in. by 26 in., driving wheels 4 ft. 3 in. diam., working pressure eo. 150 lb. per sq. in. Weight of engine in working order 48 tons. The first illustration shows an ore train at Sandtrask—near the Arctic Circle-taken in 1888. The second picture shows one of the 0-4-0 saddle- tanks shunting at Gallivare

Correspondence. 185

Early Stephenson engine, Melbourne and Hobson's Bay Railway.. Ernest F. Smith 
In our March issue we illustrated an interesting old model of a shunting locomotive built by Robert Stephenson and Co. for the Melbourne and Hobson's Bay Railway.
Mr. Er nest F. Smith has kindly sent an old photograph of the pier ta-ken by Mr. C. Nettleton and we now have pleasure in introducing it. The following extract from Mr. Smith's letter which accompanied the photograph will be of interest.
"There can be very little doubt, I think, that the engine in the picture is the prototype of the model illustrated in your March issue. On account of its diminutive size there can hardly have been a smaller one, and in any case the photo. was probably taken before the larger engine was built in 1875. What detail can be seen corresponds very closely with the model, with the exception of what I take to be a vertical board carry,ing the steam gauge. The existence of the latter , however, is chiefly conjecture on my part, as it is not too clear in the photograph. There is also what appears to be a whistle spindle running through this board, and this is fairly plain. It is quite feasible that this lltling for the gauge may have been added to the engine after she had been in service for some time, and the short whistle handle which I think can be seen in your reproduc- i ion of the model would then have to be extended so as to make it acces ible to the enginemen. It is clear from the height of the t r aver ser in front of the engine that there would have to be very considerable clearance underneath, as, of course, unless the tr aver ser is in position, there is a gap in the rails, as seen in the adjacent lines.
"You wi ll notice the two sloping rods running from the footplate alongside the boiler. I suggest that one of these is for the pet cock of the pump, and the other perhaps for the cylinder or st camch es t cocks, or perhaps feed cock from tank. These rods apparerrtly existed on each side of the engine, as shown hy the model and the photograph. In the model the pump can be seen arranged vertically on the frame between the wheels.
"The front guard. irons so conspicuous in the model do not appear in the photograph: probably they suffered too much in the rough and ready working about the wharves to allow of them remaining in position for long at a time. There appears to be a bunch of rope slings, or perhaps a towrope, draped over the exhaust pipe on the left handside of the smokebox: no doubt a very useful item in the class of work."

Locomotive design. J.G.B. Sams
I am very grateful to P. A. Hyde for taking so much notice of me, but with the exception of Sweden I propose to stick to my guns; I would say that my remarks on the above country were founded on information from what might reasonably be called a very authoritative course.
The dictionary definition of "popularity" is "general esteem" and I fail to see that roller bearings can as yet lay claim to this. However, Mr. Hyde certainly knows more about jt than I do and perhaps he will inform us through your columns of the precise number of locomotives actually fitted throughout with roller bearings in, say, this country, Africa and India. This will enable your readers to judge.

Diesel electric traction. William. T. Hoecker. 185-8
The brief article on page 132 of your May number, which quotes statistics approved by several eminent authorities, reads suspiciously like propaganda in support of Diesel- electric traction.
Using the operating cost per train-mile as a basis, no fair comparison can be made between the Southern Pacific Company's Sunbeam trains which operate on a 260-mile run, and the Denver Zephyrs, whose run from Chicago to Denver covers 1,017 miles. Furthermore, nothing is said about the relative capital investment in the two trains, involving at least a possible difference in the fixed charges for interest, depreciation and taxes, though all this must be taken into account before any dividends can be credited to the shareholders.
The accuracy of the assertion that' the daily mileage of oil- engined trains is "four times that of steam locomotives" depends entirely on what kind of steam locomotives one has in mind and upon the circumstances under which they are operated. Given sufficiently long runs, the most modern steam locomotives are daily demonstrating their ability to run from 18,000 to 20,000 miles per month without any particular difficulty. To quadruple this performance, it would be necessary for an oil-engine to run non-stop during the entire month at an average speed of 100 m.p.h.The increased availability of the oil-electric locomotive will be readily acknowledged by all, but it must also be realised that this ad- vantage can only be fully utilised if the available traffic permits a suitable arrangement of train schedules.
The Committee on Locomotive Construction of the Association of American Railroads has for sorne time been assembling statistics pertaining to the operation and maintenance of Diesel-electric locomotives, with a view to providing comparative data of an absolutely unbiassed nature. Up to the present moment, this work has not been completed. Until it is, it may be well to accept the reports of consulting engineers, no matter how disinterested they appear to be, with a certain degree of caution.
In conclusion, your readers may be interested to know that the Southern Pacific Company ,announced on 25 February 1939, an order for forty new steam locomotives of the largest and most powerful types, to cost approximately £1,500,000. This does not indicate any loss of confidence in the steam locomotive.

Heat treatment and the application of electric furnaces. -By E. F. Watson. London: Draughtsman Publishing Co. Ltd. Price 2/- net.
This publication gives an outline of the major heat treat- ment processes, dealing with the methods used, the effects on material treated, etc. Electric furnaces are described and reference made to their advantages for certain classes of work.

Liliputbahnen. WaIter Strauss. Printed in Germany.
This is the finest book dealing with passenger hauling model locomotives yet produced. Although railways of 2½ in. gauge are included, it deals more especially with those of 3½ in. gauge and upwards.
American and German models are illustrated and described but by far the greater number are of British origin, practically every model railway in the larger gauges being mentioned. Such lines as the Ravenglass and Eskdale, and the Romney, Hythe and Dymchurch naturally receive much attention, but in addition are some less known to present-day en- thusiasts, such as Sir Percival Heywood's Duffield Bank Railway dating from 1875.
The numerous illustrations are excellent, and although the text is in German there will be many who will consider the book worth purchasing for the illustrations alone.

Locomotive drawings. Stephenson Locomotive Society. 186
The Stephenson Locomotive Society are to be congratulated on the publication in a single volume of a collection of roughly 200 outline drawings representing most of the locomotive types that are or have been in service in this country during recent years. The drawings have been selected from those which have been published in the Society's Journal to which have been added a number that have appeared in the pages of this magazine as well as elsewhere. No half tone blocks' have been included. The book is not loaded up with reading matter of which there is none beyond the foreword and index, but the blocks have been printed on one side of the paper only and make a very useful reference series for all interested in the locomotive.

Locomotive Department Liaisons. 187
Comprising as it does many "industries within an industry", and many occupations and professions within a vocation the modern railway system of any size is inevitably an organisation complex in structure. To attain maximum efficiency of the whole, understanding and liaison between the various sections of this organisation must reach a high pitch of perfection; the "departmental outlook" must be avoided or if it already exists must be broken down, and a close harmony of co-operation must be attained among the almost innumerable cross-sections that go to make up the vast entity of a railway.
That the attainment of this objective presents a definite problem was evidenced by the stress laid by the largest British railway company upon the dangers of the "departmental outlook", when it recently established a training school for its personnel. The smaller is the concern, usually the more intimate is the personal contact between those responsible for its conduct· the larger the undertaking, the greater the' risk (but not necessarily the prevalence) of losing or weakening personal contacts, enthusiasm and initiative. On the other hand, the phrase "depart- mental outlook" does not necessarily imply lack of interest in or enthusiasm for the particular task which the individ ual is called upon to fulfil; a man may be one-hundred-per-cent. efficient at his own job, yet neither know nor care what is the effect of his work beyond the restricted orbit of his own particular sphere. Obviously an organisation which consists of various activities all carried on within water-tight compartments presents the potentialities of weakness, and lacks united effort or central driving force. It is in order to red uce this risk, and to encourage an interest and a morale beyond the confines of purely sectional interest, that many great organisations (certain railways among them) have devoted much thought and trouble to such functions of industrial psychology as staff Journals and educational or instructional films, which help to stimulate interest in the general work of the undertaking as well as to encourage personal efficiencv in the immediate task of the individual.
Esprit de Corps.
Two factors exist in the railway industry which make it all the more important that the "departmental outlook" should be avoided. One is the amalgamation of railways into groups, a process which has left the tradition and spirit of the con- stituents m mid-air, so to speak, whilst fresh counterparts applicable to the new undertakings. are established among the personnel. The other factor is the vast degree of progress achieved (and still m course of achievement) in almost all spheres of rail:--vay activity, more particularly on the technical side. This progress means that the technical man especially has to be constantly alert, constantly studymg, If he is to keep pace with deyelopments.. In a large railway organisation It is the function of the executive to survey and determine broad principles and for subordinates to work out the plan in detail. The rate of progress to-day is such that no man can reasonably expect, even if he. has the inclination, to keep abreast with detail m all fields of technical pro- gress. On the other hand, it is essential that he should be fully abreast of the broad trends of development in other departments whose func- tions Impmge upon his own, and that he should keep aware of changes in detail which may affect him personally. A particular example is the locomotive man (and especially the locomotive running official) who must keep in touch with what is being done by his colleague on the civil' engineermg, signalling, stores, and traffic-working.sides, so that he may be alert to the effect which such progress may have upon his own work. Traditionally the locomotive man possesses such external interest, for there were no railways worthy of the name until he provided the engines to work them, and, conversely, the other de- partments with whom the Locomotive Department is in contact and collaboration have an obligation to watch locomotive progress with equal interest and vigilance, .since they must know both the capacity and the Iimitations of the motive power used by the railway.
Bearing in mind . the foregoing conditions as they apply 'to-day, It IS not surprising to find a keen interest among all ranks of the locomotive staff, including the enginemen themselves, in phases of railway progress outside the Locomotive Department. This is all the more important nowa- days when the locomotive is regarded essentiallv as an economic unit! and not as in the old days, as a necessary but highly technical machine which the Locomotive Department alone understood and which was of no interest to other departments, so long as it duly appeared to take its train at the appointed time. and ran that train to the schedule required of it.
Locomotive Economics.
In recent years much thought and study has been devoted to the question of locomotive run- ning expenses as a factor in the overall efficiency of the railway. Standardisation and mass-production, intensive user, and the improvement of such statistics as ton-miles per engine-hour, and miles-per-day-per-engine-in-use, have all made their contribution towards the reduction of this ex- penditure, which on the four British main line railways represents an annual cost of some thirty- three million pounds.
The attention thus paid to locomotive working has, moreover, fostered an undoubted tendency to take the locomotive aspect more fully into con- sideration when planning other railway developments, so that the locomotive has become still more closely knit to railway efficiency as a whole, and has exercised a correspondingly greater influence upon it. This being the case there is a parallel tendency for the locomotive man to examine with greater interest the work and problems of other departments so far as they affect him, and it may therefore be not without profit to study some of these tendencies in other fields of railway enter- prise, from the particular standpoint of the rail- wayman whose work lies in the design, construction or running and maintenance of locomotives.

3 ft, 6 in. Gauge 4-6-2 Locomotive Gold Coast Government Railway. 188-9. illustration
Seven 4-6-2 locomotives had been constructed by Beyer, Peacock & Co. Ltd. for working main line passenger services between Sekondi, Kumasi and Accra. They had been built to the specifications of Major C. R. Turner, the chief mechanical engineer of the Gold Coast Government Railway, and under supervision of the Crown Agents for the Colonies. The cylinders were 18 inches diameter with a stroke of 26 inches. The piston valves were 10 in. dia., actuated by Walschaerts gear. The coupled wheels were 5 ft. diameter and have a wheelbase of 11 ft. equally spread. In full working order the engine weighed 63 tons 9 cwt. The boiler working pressure is 180 psi. The firebox was of the round-top pattern and had a combustion chamber. The M.L.S. superheater provided 332 sq. ft. of heating surface and this, combined with 1,358 sq. ft. evaporative surface (1,222 sq. ft. by the tubes and 136 sq. ft. by the firebox) gives a total heat- ing surface of 1,690 sq. ft. The grate is fitted with ordinary bars and had an area of 25 sq. ft. The tractive force at 85 per cent. boiler pressure is 21,480 lb.
The main frames are of the bar type and the cylinder castings are bolted together to form a saddle for the smokebox. The bogie is spring controlled and the truck wheels have Cartazzi radial axleboxes.

Metre guauge 4-10-2 locomotive, Araraquara Railway, Brazil. 189. illustration
The important Province of Sao Paulo well known for its coffee plantations, is served by the Sao Paulo and Paulista Railways from which radiate a number of metre gauge feeder railways. Amongst these is the Estrada de Ferro Araraquara serving the North Western district of the Province, and starting from Araraquara station on the Paulista Ry. An important extension is planned to be made during the next year or two, which will reach to the Parana River via the town of Rio Preto. This extension will receive traffic from the Province of Matto Grosso, which is a rich cattle rearing district. The present section of the railway traverses a hilly country with gradients of 1 in 50 and curves of 330 ft. radius. As on most Brazilian railways, the traffic varies considerably according to the season, being at its maximum during the coffee harvest. To deal with the heavy trains over this line several powerful 4-10-2 freight locomotives have been delivered from the Berlin Locomotive Works, and in regular service these engines haul train loads up to 600 tons. The boilers have all- welded steel fireboxes with a combustion chamber, and have a working pressure of 250 lb. per sq. in. The heating surface of the firebox and tubes is 3,110 sq. feet, and of the superheater 1,150 sq. feet, giving a total of 4,260 sq. ft. The grate area is 66.7 sq. feet. The cylinders have a diameter of 227/8 in. with a stroke of 24 in. Each cylinder is cast with its steam chest and half of the smokebox saddle. The driving wheels are 4 ft. 2 in. diam. The weight of the engine in working order totals 107 tons, the adhesive weight being 80 tons. The tractive power at 85 per cent. b. p. is 53,000 lb. The tender has a capacity of 706 cub. feet for fuel (wood) and 295 cubic feet for water. The weight in working order totals 48 tons. The wheels are 2 ft. 2 in. diameter and the two bogies each have a wheelbase of 5 ft. 11 in., the total wheelbase of the tender being 18 ft. 8t in. The total wheelbase of engine and tender is 66 ft. 1½ in. and the length over couplers 74 ft. 3¾ in. The special fittings include "Gresham" feed- water heater, "Wagner" water purifier, Davies & Metcalfe exhaust steam ejector, "Everlasting" blow off cocks, Westinghouse brake with cross compound compressor, pressure reverse gear with oil damping piston, electric lighting with turbo-generator, M.C.B. couplers and radial buffer between engine and tender.

L.N.E.R. Pullman Services . 190
An interesting feature of British express passenger development during the first year of grouping was the introduction by the L.N.E.R. of fast, long-distance all-Pullman trains. In July 1923 the Harrogate Pullman service commenced running in each direction every week-day between London (King's Cross), Leeds, Harrogate, Ripon, Darlmgton and Newcastle. Great Northern metals were traversed via Doncaster into Leeds (Central) , where reversal was necessary; and those of the North Eastern section northward via Geldard Junction Holbeck (low level), Arthington and Northallerton, where the main line is rejoined. A feature at the time was a non-stop run between King's Cross and Leeds, scheduled each way in 205 minutes for 185¾ miles at 54.3 m.p.h.—a welcome acceleration. For a short time until the operating staffs had become accustomed to the working, a brake check was called at Holbeck (high level G.N.) before descending the sharp gradient into Leeds.
The summer of 1925 saw the northern terminal extended to Edinburgh. The departure time still remamed 11.15 from King's Cross, though Waverley was left in the up direction at the comparatively early 'hour of 08.30. Since the distanoe to be covered, however, was so much longer, the arrival time in London became 17.05, or nearly two hours later than hitherto. In the autumn of the same year, upon the introduction of the winter timings, the Edinburgh Pullman was routed via Knottingley and Church Fenton instead of by Leeds and made daily non-stop runs each way over the 198¾ miles between London and Harrogate. A stretch of L.M.S. (Central Div.) track was traversed between Shaftholme Junc. and Knottingley as in the days of the pre-WW1 G.N. through Harrogate runs. At the same time in order to serve Leeds, also Bradford (via Leeds) a separate all-Pullman express was inaugurated which required two trains, in order to provide a morning service similar to that afforded before the original train started from Edinburgh. In 1926 a Wakefield stop was added. enabling a faster Bradford connection to be given via Wakefield by means of through cars which commenced to serve Halifax also as their northern terminal.
In 1928 the Queen of Scots was inaugurated, the northern terminal being Glasgow (Queen Street). The Church Fenton route was abandoned, and running through Leeds resumed. The overall time for the 460½ miles was 9½ hours, with 8 hours 20 minutes between King's Cross and Edinburgh, Waverley. In the same year the schedules of the West Riding trams were entirely rearranged with an extension to Newcastle again, which city became the home station of the one set of cars which was now necessary. Leaving Newcastle at 09.15., and calling at Darlington, Ripon, Harrogate, Leeds and Wakefield whence a 57.6 m.p.h. run over the 175¾ miles to King's Cross furnished an arrival at 15.00. The return journey thenceforward commenced at 16.45, with a similar booking, thus providing a new evening facility and constitutmg a dally run of 567½ miles, which was probably the longest daily mileage in Britain achieved by the same set of vehicles under similar conditions. The two Bradford-Halifax cars continued to be attached or detached 'respectively at Wakefield.
In May 1932, in common with the other East Coast day expresses, a considerable speeding up was effected the Queen of Scots schedules:. The starts from King's Cross and Waverley became 11.20 and overall times were reduced as follows:—Between London and Glasgow 9 hours, London-Edmburgh 7 hours 55 minutes, in each case the Leeds route was followed which is over 20 miles longer than, and considerably harder than, the line through York.
The 1935 changes in the other train's doings altered its title to Yorkshire Pullman. It does not work north of Harrogate, owing to the advent of Newcastle's streamlined flyer—the Silver Jubilee-—but it has successfully tapped fresh fields.
Through cars are run between Hull and King's Cross, giving a new 3½-hour service. The Harrogate portion southbound goes via York which city receives a Pullman service for the first time, while the cars from Halifax, Bradford and Wakefield (whose patronage on the outward journey has been largely swallowed by the West Riding Limited high speed train) form a third section into Doncaster, the other additional centre served. The combined train sets off at 12.25 to cover the 156 miles to King's Cross in 155 minutes, being due in London a 15.00., and still starts back at 16.45. A similar run to Doncaster ensues, but the original working to Harrogate via Leeds is followed.
Since this 1935 retiming, a Gresley 4-6-2 engine from Doncaster shed has regularly worked the Yorkshire Pullman over the main-line in both directions. One of the A3 super-Pacifies with three 19 in. cylinders and 220 lb. pressure is usually seen; a new streamlined A4 with Kylchap blast pipe and chimney occasionally takes the turn. The Pullman running over the Great Northern section was for many years of particular in- terest to students of locomotive performances by reason of the continuous employment of Ivatt's famous Atlantics. For a while in the early years under review, Great Central 4-cyl. 4-6-0 engines of the Lord Faringdon class were employed to a considerable extent. They then still had Stephenson link motion between the frames actuating the steam distribution to both inside and outside cylinders, and were hardly ideal performers on these runs. After their withdrawal, for a period Robinson's newer G.C. 4-4-0 Directors took a share from the Leeds end and put up some good performances. The Shire class 3-cyl. L.N.E. 4-4-0 has been tried, but normally GN. 4-4-2s held undisputed sway otherwise until 1935-6. As modernised they have piston valves, 20 in. cylinders. and 32- element superheaters, but retain their 24-in. stroke and 170-lb pressure, Notwithstanding the fact that they were four-coupled engines twenty to thirty years old, their average performance in the hands of keen, regular drivers and firemen was not only consistently good but was also comparatively economically achieved, and King's Cross has been reached in less than three hours from Leeds: from Doncaster, 156 miles, in an actual time of no more than 141 minutes and probably in 138 minutes net with nearly 300 tons! Over erstwhile N .E. metals and on to Edinburgh, Raven 3-cyl. 4-4-2 locomotives took a considerable share in the past, though Pacifics are now practically always employed through between Leeds and Edinburgh. Various engines of the older constituent companies' types haul the Pullman sections in Yorkshire while standard L.N.E. Shire or Director 4-4-0' again appear sometimes on the Queen of Scots 'twixt Glasgow and the Scottish capital. In November 1936, replacing the last regular" Atlantics" rostered to the Leeds- London fast running (though they remain in reserve for the duty) two A1 class 180-lb. "Pacifics" with three 20-in. cyls. took over the Queen of Scots and Harrogate Sunda'y Pullman regularly with notable success. This review would be incomplete without a brief reference to the Sheffield Pullman services which were tried in 1924-5. Firstly, the route was via Grantham, Nottingham (the only stop) and over the G.C. main-line to Sheffield. The next stage in its short history was a retiming and a run through to and from Manchester (Central); ot- tingham being abandoned.
A most successful summer development in recent years of a different category has been the running of all-Pullman 1 st and 3rd class cheap half-day excursions from Liverpool St. to different destinations daily. Hauled by Sandringham ("B 17") 3-cvl. 4-6-0 locos., or else the reb~ilt G.E. 4-6-0 engines of class B 12/3 on non-stop runs to Norfolk and Suffolk resorts these trains often provide the fastest services of the day. The Pullman Company has recently ordered seven new cars for the L.N.E.R. services. They are to be built by the Birmingham Railway Carriage and Wagon Co. of Smethwick Illustrations: The Harrogate Pullman leaving King's Cross in 1925, hauled by G.C. 4·cyl. 4-6-0 Lord Faringdon.

Noise reduction and improved ventilation. 192  diagram
The continual demand for noise abatement made by railway travellers has been met to a considerable extent by using efficient sound absorbing materials for the floors, roofs and ends of carriages but the trouble still remains, due mainly to open ventilators when passing through tunnels and long stretches of line where sound rebounds from the retaining walls. S.H.H. Barrett, patented a neat and effective method of insulating these noises and at the same time improving the ventilation. As will be seen from the accompanying drawing the ducts formed in the roofing and walls of the vehicles are lined with sound-absorbent material in connection with a double-glass ventilator through which fresh air can enter whilst noise is excluded. A system which provides for the introduction of air into railway carriages but which cannot be adjusted by the passengers is open to objection, and it is generally understood that passengers like to feel fresh air coming into the compartments through ventilators which they can regulate themselves. Ventilators are, of course, already in use which allow of the movement of glass and metal vanes above the main windows through which air can be admitted or extracted according to their adjustment to the direction in which the train is running. These, however, do nothing towards. excluding noise, but with this new arrangement  it is proposed that the ordinary extractor ventilator in the roofs of carriages be retained. An advantage of the system is that there are no projections out- side the carriage to affect the streamlining of the vehicles or cleaning the carriage sides, windows and ventilators.

Cost of stopping trains. 192
The Signal Section of the Association of American Railroads presented a report, at the annual meeting, showing the cost of stopping trains. These costs were Ibased on trains of different weights hauled by four types of locomotives. The figures obtained were of fuel and water costs only, such items as brake shoe wear and damage to equipment not being included. It was found that the stopping of a 6,450 ton train composed of 80 ton cars on a level track from a speed of 45 m.p.h. wasted energy equivalent to 345 h.p. hours. Expressed in cost of fuel and water this represented $2.08, while a stop of six minutes' duration brought this figure up to $2.37.

L.N.E.R. 192
Four further V2 class 2-6-2 engines had been completed at North Road Works, Darlington, Nos. 4833. 4834, 4835 and 4836. No. 4831 is named Durham School. No. 1439, class J77 had been withdrawn and Nos. 1330, 1530 and 2161, class A8, had been fitted with new boilers.

P.C. D[ewhurst], L.M.S.R. locomotives: a history of the Somerset and Dorset Joint Railway. 193-5. 2 illustrations
Continued from page 136. The next engines introduced were the Johnson "Joint-line" goods engines and here again something apparently like, but in this case more distinct than, a M.Rly. standard class appears. The first batch were supplied by Neilson & Co. in 1878, WN 2269-74, and these were given S.& D.Jt. numbers 33-38—following on the previous tank engmes—and they are illustrated when built at the makers' works by Fig. 32, the table of dimensions being appended. It will be noted that these locomotives were less powerful than the previous :'Fowler" goods engines, not only in respect to their rated tractive force, but also in having a 6 in. shorter firebox.
They being the first Johnson tender engines on the Joint line, a fairly extensive notice of their features is given, in a similar manner to the tank engines. The constructional features of the boilers, including the regulator, were all as described for the Avonside tank engines, but the size and heating-surfaces and the height of centre above rails followed the M.Rly. 0-6-0 4 ft. 6 in. side-tank engines of the 1874-6 period although the "Joint" engines had 215 1¾i-in. tubes instead of the 220 1¾i-in. tubes of the former; the reduction being due to a re-arrangement of the tubes to give more clearance from the bottom of the barrel. The cylinders, motion, rods, wheels, wheelbase, etc., were also the same; in fact, the" Joint" engines were practically a tender engine edition of the M.Rly. 0-6-0 tank engines, the details of the parts just mentioned, and in addition the spring gear, also being the same as the Avonside tank engines except as otherwise described below.
The injectors were of the non-lifting type, located behind the footsteps under the cab side-sheets and delivering to clack-boxes on the middle ring of the boiler-barrel. The connecting-rods were 5 ft. 10t in. long, but the coupling-rod cranks were 22 in. throw as before. The brake comprised cast-iron blocks to the front of all six wheels, the hangers being of two-plate pattern, the pull-rods outside the wheels being operated from a brake-shaft running right athwart the rear of the engine having no bearing in the main frames but being bracketted to each of the outside foot- steps and having a steam brake cylinder placed vertically in the middle under the drag-casting and applying pressure downwards from steam behind the piston; the brake release-springs were placed under the ashpan. The outside pull-rods were standard throughout the later series of this class -as they were on the 0-6-0 tanks of M.Rly—not re-designed with inside pull-rods of progressive forms as was done on the later designs of M. Rly. tender goods engines.
The chimney and cab, also dome and safety-valve casings, were of the usual Johnson style. The dome casing differed from the earlier form as on the A vonside tank engines, the dome cover being 2 in. shorter and thus although the dome itself was of the earlier M.Rly. height the casing was almost the same as the later M.Rly. form. These " Joint" engines were thus the first to have the lower dome top bringing the spring-balances slightly lower and thus producing the more generally known form of Johnson dome casing as distinct from that having a rather attenua- ted waist below the decorative top which had hitherto appeared on all Johnson engines
The motion, as before mentioned, followed that of the 1874-6 Johnson 0-6-0 tanks, there being a somewhat longer reversing-rod lever than that used later and carrying the axleboxes, springs, etc., whilst the inside, ft in. thick and 1 ft. 1 in. deep, and carrying the brake-hangers, extended from behind the dragbox to the rear buffer beam. This latter was a simple plate type not of sandwich pattern. The tank was similar to the water-bottom type and having a well 1 ft. 6 in. deep, but there was no raised level for coal-shovelling, the top-plate of the tank curving at the front right down to the running plate level and there was a slightly inclined shovelling-plate providing a lip 4t inches above the tender foot-plate. The diameter of the wheels (with 2t inch tyres) was 4 ft. 6 in. The brake-hangers were of the double-plate pattern with pull-rods outside the wheels, operated from a brake-shaft bracketed in the main frames and having a steam cylinder placed vertically in the centre and applying pressure downward from behind th~ piston; there was of course the usual hand auxiliary—on the left side—connected to the same shaft. Vacuum brakes were fitted to these engines in the late 1880's
The above-mentioned engines were quickly followed by similar ones; Nos. 39-44 built by the Vulcan Foundry Co. in 1879, makers' Nos. 840- 845, and whereas their predecessors had followed the M.Rly 0-6-0 tanks of 1874-6 design these Vulcan engines were tender editions of the M.Rly. 0-6-0 tanks of 1878 (which design lasted through to 1892 on the M. Rly.). Hence, although generally the same as Nos. 33-38 there were differences which will be described.
Further batches of identical engines came from the Vulcan Foundry, Nos. 25-28 in 1881—when old engines Nos. 25-28 became 25a to 28a—makers' Nos. 896-9; 46-51 in 1884 makers' Nos. 1055-60 and finally, after an interval during which some 0-4-4 side tank engines next to be described were received, Nos. 56-61, makers' Nos. 1264-9, in 1890 making with the Neilson's a total of 28 locomotives. Fig. 33, showing engine No. 50 illustrates the whole class. These Vulcan-built goods differed from the Neilson in various small details—most of which have been indicated when describing the Neilson engines—but the inside firebox was also different in shape and this varied the tube heating-surface. The motion of the Vulcan's however strictly fol- lowed that of the M.Rly. 1878, and later, 0-6-0 tanks, the reversing lever moving through 33 deg. which was slightly more than the tank engines but equal to that standard on M.Rly tender engines throughout Johnson's time; the cylinder-cock gear' on the Vulcan's also differed from the eilson's in having an intermediate swinging T-piece Instead of a double-ended lever reversing the rod movement in the neighbourhood of the motion-plate, which was the arrangement on the latter engines. The Vulcan engines also had driving wheels 4 ft. 6t in. on tread, this being due to the adoption of 2i in. tyres instead of 2t in. as used on the previous engines.
In the later batches the coupling-rods were somewhat heavier at the eye-ends and there was less "shaping-up" to the oil-wells; also apparently all the Vulcan's had the taper-pins of the coupling rod caps placed at 90 deg. with a radial line from the axle-centre, instead of in line thereto and driven in from the centre towards the circumference as was Johnson' s usual—and better-practice. Although the tenders supplied with the Vulcan engines were very similar to the Neilson, there were some differences. The former were identical with similar tenders to M.Rly. whereas the latter had very "arched" frame-spaces between the horn-plates and the frame-space ahead of the Jeading horn-plates was circular, and in these respects the eilson's differed from the M. Rly. standard.
The vacuum brake was fitted to these engines by about 1890. At about the same time they .and others generally upon the S.& D. Jt.) were fitted with sight-feed lubricators to the valve-chest, in place of the Roscoe lubricators previously in use, and the delivery-pipe passed through the left side hand-rail even as the right hand-rail—enlarged—was made to serve as part of the vacuum "train-line-pipe." The rebuilding of the earliest of these engines commenced In the late 1890's.

L.M.S.R. 195
An important milestone in railway development in the North of England—the public opening of the first section of the Manchester and Leeds Railway, later part of the Lancashire and Yorkshire Railway and now part of the LXl.S. system reached its centenary on 4 July 1939. Proposals for a railway between Manchester and Leeds were mooted as early as 1825, and the route was surveyed, and the line constructed, by George Stephenson, who regarded the Summit Tunnel, between Littleborough and Walsden, as the greatest piece of railway engineering he had yet achieved. This tunnel is 2,885 yards long and is the eighth longest on the L.M.S. system; it cost over £250,000 and required the labours of 1,000 men for nearly four years. At its deepest point the tunnel is 300 ft. below the Pennines. It was owing to the Summit Tunnel being unfinished that the line could not be opened further than from Manchester to Littleborough, 14 miles. on July 4th, 1839. At the opening there were only eight trains a day in each direction, whereas at the present lime about 150 trains pass through Littleborough on a normal day, and about 200 in the holiday season. The original Manchetcr terminus of the Manchesrer and Leeds Railway was at Oldham Road, which is now an important L.M.S. goods station (dealing with about 2,000,000 consignments per annum. and where traces of the original buildings were still to be seen. Passenger trains were transferred to Hunt's Bank [later Vicroria) Station in 1844. Among interesting features of the railway were its employment at first of the unusual gauge of 4 ft. 9 in

Great Southern Railways. Thc three engines of the 800 class to be named after Irish Queens as Iollows:. 800 Maeve, No. 801 Macha; No. 802 Tailte, The name plates will have bronze lettering (in Irish) on a blue background. No. 800 wouldl be in regular service on 17 July. The second engine, No. 801, was approaching completion. It is understood that the up and down Cork day mail trails were to be accelerated by 15-20 minutes in each direction.
The locomotive shed at Wexford was to be closed, and the engines work through to Rosslare Harbour where the shed had been enlarged. This has involved strengthening the bridges between Wexford and Rosslare.
Sleigo, Leitrim and Northern Counties Railway.-No. 1A railbus was at Dundalk , and to take its place G.N.R. (I.) railbus D has been lent to the company. There were two railbus workings in each direction between Sliigo and EnniskilIen.
Londonderry and Lough Swilly Ry. Nos 7 and 13 (4-6-2T') and 17 (0-6-0T) were lying derelict at Pennyburn shed, Londonderry, and No. 1 (4-6-0T) was under repair. Nos. 2, 12 and 14 were working Burtonport trains. Goods trains still worked to Buncrana, but beyond that to Carndonagh the line was completely dismantled.

Tube extension. 195
Highgate to East Finchley.-The first part of the North London eleotrification scheme, covering a distance of two miles between Archway (Highgate) and East Finchley, opened for service on 3 July. The new line has a physical connection with the L.N.E.R. at East Finchley and uhere will be a new tube station at Highgate underneath the L.N.E.R. By invitation of the L.t .E.R. and London Transport, Lord Ashfield and Sir Ronald Matthews, the chief officers of both systems, and a number of guests attended a private inspection of the line a few days before the opening. On this occasion a special train ran non-stop from Leicester Square Station to Archway—where Sir Ronald Matthews entered the motorrnans cab and piloted the train over the new line.

Southern Railway electrification. 195
On Sunday, 2 July, electric trains were brought into public service on the GilIingham and Maidstone lines. Seventy-six 550 h. p. two-car trains hade been built at Eastleigh and Lancing for this extension. Half of the stock was provided with side corridors and lavatory accommodation. Each train set had a seating capacity for 24 first class and 102 third class passengers.

Further 2-S-0 freight engines turned out at Crewe were Nos. 8123-25, thus completing the present order. The first of the new streamlined Princess Coronation class 4-6-2s, finished in red and gold livery, had left the Crewe shops, No. 6235 City of Birmingham. No. 5518 of the 4-6-0 Patriot series had been named Bradshaw, in commemoration of the centenary of Bradshaw's railway guide which takes place this year. A total of fifty ex L.N.W. 0-8-0s of class G1 had the boiler pressure increased from 160 lb. to 175 lb., the power classification being also raised from 6 to 7. Recent additions to the series, which is officially designated class G2A, included Nos. 9045, 9130, 9185 and 9356. Withdrawals included ex-LNWR superheated 4-4-0s Nos. 25293 Levens and 25409 Dovedale, also ex Mid. 4-4-0s Nos. 722, 723, 750 and 777. Six new 0-6-0 Diesel eleotric locomotives ex Derby were now in traffic, Nos. 7080-85.

Railway was incorporated in 1862. The LNWR provided capital to develop port at Greenore at the end of the Carlingford Peninsula and the railway to serve it and connect it the GNR (I). The locomotives were 0-6-0ST built at Crewe: Nos. 1 Macrory, 2 Greenore, 3 Dundalk (Crewe Works Numbers 1509-11 of January 1879), Nos. 4 Newry and 5 Carlingford (Works numbers 1962-3 of January 1876) and 6 Holyhead (WN 3877/May 1898). The locomotives and carriages werre paintred in LNWR livery. Prior to WW1 a GNR (I) through train with dining car ran to Belfast connecting with the boat from Holyhead. The division of Ireland left the port in Ireland with its main source of trade in the so-called United Kingdom and the sea route waas restricted to freight. In 1933 the GNR(I) took over the railway and brought in its JT class to work the passenger services and presented iit with two railbuses Nos. 1 and 3. The route passed through beautiful country

The centenary iof the Eastern Counties Railway. 203-6
Several attempts to build railways into rural East Angia failed, but on 4 July 1836 the Royal Assent was received for the Eastern Counties Railway. It was built vto the 5ft gauge, but the earthworks were constructed to accept 7ft gauge. In late 1838 a temporary terminus in Devonshire Street, Mile End provided a train service to Ilford and this was extended to Romford on 15 June 1839. On 4 July 1840 the line was extended inward to a terminus at Shoreditch and outward to Brentwood amd this opened in the presence of the Persian Ambassador. On 29 March 1843 Colchester was reached.
The Northern & Eastern Railway sought to exploit the Lea Valley to escape from London. It was also built to the 5ft gauge and relied upon the ECR for its terminus in Shoreditch and on its line as far as Stratford where it set off to the north, but the toll rate was a problem and it was leased by the ECR from 1 January 1844: the lines were converted to standard gauge in September 1844. Broxbourne had been reached by 18 September 1840; Bishops Stortford in 1842 and Hertford on 31 October 1843. Norwich was linked with Yarmouth on 1 May 1844 and later in the same year the Norwich to Brandon Railway was amalgamated with it to form the Norfolk Railway. Norwich was initially linked to London via Brndon and Ely and under the auspices of the Eastern Counties Railway much of East Anglia was eventually reched including King's Lynn, Peterborough and Hitchin (the last was sold back to the Great Northern). The Eastern Union Railway linked Colchester to Ipswich and Norwich and was worked by the ECR from 1854.
The Eastern Counties Railway after a somewhat checkered history from the financial aspect, at the time of its absorption into the Great Eastern Railway owned or leased 299 route miles of track to which should be added the Norfolk Railway, 92 miles, the East Anglian Railway 67 miles, the Eastern Union Railway 106 miles, the East Suffolk Railway 69 miles and the Wells and Fakenham Railway 9 miles. The Eastern Counties Railway thus formed the main portion of what became one of the principal trunk railways in the country prior to the grouping scheme of 1923.
The finances of the Eastern Counties Railway were never in a strong position and in an attempt to remedy the position George Hudson was in October 1845 invited to join the Board, which invitation he accepted, and became Chairman of the Company with almost dictatorial powers. It was largely at his instigation that the locomotive and carriage works at Stratford came into existence, the original premises being completed and brought into use in 1848. Previous to this the locomotive shops were located near Romford on a site which was in 1939 still known as Romford Factory.
On the formation of the Great Eastern Railway in 1862 the Eastern Counties Railway owned 330 locomotives, whereas at the opening of the first section of the line in 1839 the number was only twelve. The earliest locomotives used on the Eastern Counties Railway were four four-wheeled engines with inside cylinders and bar framing built by Braithwaite, Milner & Co., of New Road, London, in 1838, and named Essex, Middlesex, Norfolk and. Suffolk respectively. These were known as the ballast engines, and they do not appear to have done much work other than on the construction of the line.
The first passenger engines comprised six locomotives of the 2-2-0 wheel arrangement built by Braithwaite, Milner & Co. in 1839. Thev had inside cylinders 12 in. diameter by 18 in. stroke, and 6 ft. 0 in. diameter driving wheels, and were known as Nos. 1 to 6 on the Company's books.
The remammg two engmes were of the 0-4-0 type with 5 ft. 0 in. driving wheels and inside cylinders 14 in. diameter by 18 in. stroke., and were intended for working the goods traffic. The first Locomotive Superintendent of the Eastern Counties Railway was John Braithwaite. In 1843, the mechanical side was separated from the remainder of the Engineering Department and Fernihough was appointed Locomotive Superintendent who resigned in 1845 and was succeeded by Scott, who was a protege of George Hudson. In 1846, John Hunter took charge, and in August, 1850, . J. V. Gooch, formerly Locomotive Superintendent of the L.S.W. Railway, was appointed to the position. He held office until 1856 and was succeeded by Robert Sinclair, from the Caledonian Railway: he continued in office for some years after the formation of the Great Eastern Railway.
Many improvements and extensions followed consequent upon the formation of the Great Eastern Railway, one of the most important of which was the extension to Liverpool Street Station, which was opened for traffic on the 2 February 1874 at a cost of £2,000,000, and the consequent abandonment of the Shoreditch (later known as Bishopsgate terminus.
In conclusion, it will be appreciated from the foregoing paragraphs what an important part the Eastern Counties Railway and its allied lines played in making the railway system of East Anglia what it is to-day.

G.I.P.R. track recording car.. 206
A standard bogie coach had been converted to a track recording car for detccting and recording defective sections of track. The car has a verandah at one .end leading into the instrument room in which the detectors, recorders, switchboard, electrically driven air compressor, etc., are located. The remainder of .the coach is reserved for the staff. Many ingenious devices have been introduced by Mullineux of the G.I.P.Ry., who was also responsible for the conversion and details of design.

"The Pngeant of the Railroads" at the New York World's Fair. 206
Story of transport in the U.S.A. from the days of the covered road wagon to the present time streamliners. The stage on which the spectacle appears is 250 feet wide by 100 feet deep, and on its forepart there are two tracks capable of supporting the largest present day locomotives. Some of the earlv engines in the pageant are the Stourbridge Lion (1829), Best Friend of Charleston. (1830), De Wilt Clinton (1831), and Peter Cooper's Tom Thumb. The modern engines are changed from month to month, i.e., in May the D. L. & W. 4-6-4 No. 1939 and the Pennsylvania Streamline Pacific No. 3768, in June the N.Y.C. & H. R.R. Commodore Vanderbilt; to be followed this month by the Canadian-Royal Train Engines.

A century of Austrian loco. practice. 207-8. illustration
Continued from page 44.. From what figures are available it appears that in 1880 the locomotive stock of the principal railways in Austria had reached a total of almost 2,400, exclusive of Hungarian locomotives. The individual totals were as follows, the figures in brackets being the opening year of the company or of the oldest of its constituents: K.F.N. B. (1838), 329; Siidbahn (1841), 564; State Rly. Co. (1845), 590; Galician Karl-Ludwig's Bahn (1856), 169; Westbahn (1858), 331; Kaiser Franz- Joseph's Bahn (1868),117; Kronprinz Rudolfs- bahn (1868), 114; Austrian North-Western (1869), 149; and the Vorarlberger (1872), 13.
Compounding in Austria began in 1879 with unsuccessful experiments on the K.F N B. with a two-cylinder compound 2-4-0 engine, Juno , which was rebuilt from a simple-expansion engine. In 1884 a Webb uncoupled 2-2-2-0 three-cylinder compound was built for the State Railway Company by Sharp, Stewart & Co., but does not appear to have been a success, although six or seven years after its delivery it was used to obtain data on receiver pressures to apply to the first Golsdorf two-cylinder compounds. This engine was named Combermere.
The double-expansion principle was developed continuously from 1889 up to the war years and was closely connected with the younger Golsdorf , Experiments were made by Steg with an old 0-6-0 and an old 0-8-0 locomotive in 1889 by fitting an enlarged cylinder on one side and raising the boiler pressure from 128 to 142 lb. per sq. in. In the same year Steg built for the Austro-Hungarian State Railway Company a three-cylinder compound 0-6-0 locomotive which had one inside high- pressure cylinder 15¾ in. by 25½ in. and two outside low-pressure cylinders 17½ in. by 25½ in., all of which drove the middle coupled axle. The 57½ in. wheels were spread over a base of 13 ft. 8 in.; slide valves were used and actuated by three sets of Allan link motion, two sets being outside. The boiler pressure was 156 lb. per sq. in. and the working order weight 41½ tons. In the same year the K.F.N.B. ordered from the Wiener Neustadt locomotive works, which had then passed out of the hands of G. Sigl's company, a series of 14 inside-framed outside-cylinder 0-6-0 engines, Nos. 511-524, of which Nos. 515-518 were simple-expansion engines with two 18 in. by 26 in. cylinders, and the remainder were two-cylinder compounds with an 18.9 in. by 26 in. high-pressure cylinder on the left and a 29½ in. by 26 in. low- pressure cylinder on the right. The wheels were 56¾ in. diameter, the boiler pressure was 156 lb. per sq. in., and the working order weight was 42 tons.
For the next 25 years the history of Austrian State locomotives was one of two-cylinder and four-cylinder compounding, although simple-expansion locomotives were to be found on the Hungarian division. About 1894 a three-cylinder compound 4-4-0 engine was built for the northern section of the Vienna-Marchegg-Bratislava-Budapest division. In 1897 two 68-ton Consolidation two-cylinder compound engines to the design of Karl Golsdorf were built art Wiener Neustadt for operating express trains over the Arlberg route, the loads taken being 180 tons unassisted westbound and 225 tons eastbound. These engines were very large for their time, and had a 21¼ in. by 25 in. h.p. cylinder and a 31½ in. by 25 in. l.p. cylinder. The boiler had a heating surface of 2,690 sq. ft., a grate area of 36 sq. ft., and a working pressure of 190 lb. per sq. in. The valves above the cylinders were actuated by Walschaerts valve motion and the drive was to the third pair of 51 in. wheels. These engines had an adhesion weight of 56 tons, and were amongst the first to have the familiar Golsdorf feature of two domes with an external connecting pipe. They were followed in 1898 by another six for the State Company and by seven for the Semmering section of the Siidbahn. In 1900 a two-cylinder compound Mogul engine was built for the Austro-Hungarian State Railway Company, but tests showed it to have a coal economy of only 3 per cent. compared with similar two-cylinder simple-expansion locomotives. In the same year some 65-ton 0-10-0 engines were built for the heavily-graded lines in the Bohemian mining district; they had a 22 in. by 25 in. h. p. cylinder and a 33½ by 25 in. l.p. unit, 51 in. wheels, a boiler pressure of 200 lb. per sq. in., a heating surface of 2,180 sq. ft., and a grate area of 32¼ sq. ft. The first, third, and fifth axles had a play of 28 mm. per side on what is usually, but rather erroneously, oalled the Golsdorf system. Two-cylinder compound 4-4-0 engines began to appear in numbers in 1898, when a dozen were built by Steg works, and numbered 10.601-10.612. Others were built by Steg, Floridsdorf, and Wiener Neustadt up till 1902, when there was a total of 99 engines numbered consecutively. The cylinders were 19¾ in. and 30 in. by 26 in., and they drove 7 ft. 1 in. wheels; the boiler was 4 ft. 8 in. in diameter and had a heating surface (water side) of 1,675 sq. ft. and a grate area of 32 sq. ft. The weight was 55 tons and the adhesion weight 28½ tons. From 1904 to 1906 Series 10 was supplemented by 45 engines classified Series 20; the principal external difference was the suppression of the two domes and connecting pipe of Series 10 in favour of a single dome on the back ring; the boiler was of the same size but was pitched at a height of 9 ft. 2 in. above rail level instead of at 8 ft. 6 in. The heating surface was 1,605 sq. ft., but 142 sq. ft. was from the firebox against the 123 sq. ft. of Series 10. The working pressure was 185 lb. per sq. in. in each case; the wheels and wheelbase were the same, but the second engines weighed 54 tons, of which 28½ tom was on the coupled wheels. Seventeen of the Series 20 engines were built by the First Bohemian Works (Erst bohm mahrische Maschinenfabrik) and the remainder by Steg, Wiener Neustadt and Floridsdorf.
The Golsdorf compound system was applied at this time not only to the engines of the big lines but also to those of the Vienna Stadtbahn, where many two-cylinder compound 2-6-2T locomotives were set to work. The cylinders of these engines were 20½ in. and 29¼ in. by 25 in., and the wheels 51 in.; the height from the rail to the top of the chimney was 14 ft. 11½in. Thirty of these engines were built by Steg, Wiener Neustadt, and Floridsdorf in 1896-97, and 25 by the same three works in 1898-99, and one of them was shown at the Paris Exhibition in 1900. From 1897 to 1901 another 50 to the same design were built for the State Railways. Another development about the same time was the Brotan water-tube boiler, which was fitted first to a heavy lignite-burning 0-8-0 engine in 1901. Brotan himself was an engineer on the State lines, and his invention comprised a water-tube firebox with walls of vertical tubes leading up to a water and steam drum, which was carried forward above the smoke-tube type of barrel as far as the smokebox, and connected lo it by two or three short necks. Steam was led to the cylinders by outside pipes from the front of the top drum. The Brotan boiler eventually had a large-scale application in the old Empire, and on the Hungarian lines was in use until the present decade.

The Institute of Transport. 208
The Annual Congress was held at Southampton, 14-17 June and was attended by the President, Gilbert Szlumper, and over three hundred members and friends. After Szlumper had formally opencd uhe conference, Bilbrough of Birmingham read a paper advocating the establishment of a National Transport Board. The difficulties arising from the creation of such a body were emphasised in the subsequent discussion by Sir Joseph Nall, Ashton Davies and others. In the evening, an official reception in the Guildhall of the palatial new Civic Centre was held by the Mayor and Mayoress of Southampton.
The following morning the Eastleigh Works of the Southern Railway were visited. The principal interest here was in the completion of the order for new coaches for the Maidstone electrification. The driving ends of these trains, 76 in number, are all of a new welded all-steel construction. The building jig was observed for the erection of the first of a series of all-steel coaches for steam traffic, whilst some hopper wagons for the Company's own ballast traffic were nearing completion. -
The newly-adopted livery of the Southern locomotives was in evidence, This is bright "Bournemouth" green with black edging and yellow lines for the Lord Nelson and Schools classes, and darker "Dover" green with the same lining for the other passenger classes, goods engines remaining unlined black as hitherto.
Most of thee painting is now done in the erecting shop and starts as soon as erection commences so that the painting is finished before the valve sebting and later adjustments are made. This enables the time taken for the complete overhaul of a locomotive to be reduced to 22 working days. The last four of the order for 20 Q type 0-6-0 mixed traffic engines were the only new Iocomotives in production. These engines are built in jigs, as has been the custom at Eastleigh for some years past.
The whole of Friday was allocated to the Docks. In tlie morning a paper was read by Mr. Biddle, the Docks and Marine Manager, followed by a new cinema film. After lunch a tour of the Docks was made, the day finishing with the Institute's Dinner aboard the SS. Alcantara. Other visits were made by various seotions of the delegates to the Airport, Bus Depots, and the works of Messrs. Thornycroft, Cunliffe-Owen, etc. On Saturday, a very enjoyable trip in the Solent and Spithead, in which all took part, concluded an excellent and instructive congress.

Engineeri:ng questons and answers, Vol. 2.:Manchester: Emmott and Co. Ltd.,
This volume of 176 pages, wel1 illustrated with line diagrams and sketches, contains a collection of questions sent to the Mechanical World between 1900 and 1938, together with the answers supplied. The value of this collection lies in the fact that the questions all arose originally out of difficulties encountered by engineers in the course of their work. A great diversity of subjects is dealt with, and the book wil1 be useful to many as a compendium of modern engineering practice.

Locomotive running department. J.G.B. Sams. London: The Locomotive Publishing Co. Ltd.
Although only consisting of 104 pages the author has con- trived to include in this booklet a mine of information of value to all connected with the running department of a large railway. He has based his remarks on personal experience of which he has had a good deal both in this country and the colonies, and the procedure described in quite up to date and is exemplified by instances taken from actual railway practice. The work is divided into seven chapters covering depots, plant, engine workings, storekeeping, failures, breakdowns and operation, each of which, in addition to describing the various methods of dealing with the subject under review, include a number of useful illustrations and specimens of actual .forrns and diagrams now or recently in use. These examples appear to be largely taken from the Kenya and Uganda Railway and the Great Eastern Section of the L. & N.E.R., on both of which the writer has had considerable experience.

L.M.S.R. 213
At the annual presentation of Shields to the Ruinning districts in the Motive Power League (for the reduction of Engine Casualties) held at Euston last month, reference was made by T.W. Royle, the Chief Operating Manager, to several records which had been attained during 1938, The past year had produced the highest miles per casualty figure; in the last four weeks the debitable engine casualties only amount to 202. the lowest on record; Plaistow District had achieved a splendid hat-trick by winning first place in the last three years competitions, their aggregate points being the greatest so far and the struggle amongst the districts in the centre of the league had been more intensivc than ever before.
In presenting the awards, Lord Stamp, the Chairman of the L.M.S. said that the comperitions did not lose interest as the years went by but that with thc remarkable improvement shown it was going to be more and more difficult to improve, and he jocularly visualised the time when there would be no casualties at all. He referred to visits paid to this country by railwnv experts from abroad who studied our methods of working and stressed the point that we in turn may learn from them"
Ashton Davies (Actiing Vice- President) and D,C. Urie (Supt. of Motivc Power) also spoke, the latter calling attention to the fact that out of between 80,000 and 90,000 locomotive axle bearings in use every day, 7 only per day gave trouble by overheating. The shield-winning districts were placed as follows:- 1. Plaistow; 2, Bristol; 3, Shrewsbury; 4, Bescot; 5, Derby; 6. Motherwell; 7, Carnforth; 8, WelIingborough; 9 Bank Hall; 10, Crewe,

Correct crank spacing on three-cylinder locomotives. P.C. Dewhurst
Re article in May Issue gives in extenso the proof of the correctness of the method—adopted by most locomotive designers, including the writer—of arranging the centre crank of three-cylinder non-compound locomotives at 120 degrees. plus and minus—or plus and minus whatever nominal angles may exist in a compound design—according to the angle variation of the inside cylinder to the two outside ones, which, indeed, a priori (i.e. geometrically) is evidently correct. It may be of further interest to mention that a disadvantage, unfortunately inherent, in the three-cylinder (non-compound) arrangement is the spacing of the coupling-rod pins at 120, deg. and 240 deg.; this gives very considerable variation in the effective transmission of the load from the main driving to the other coupled wheels, being at its worst when the crank of the inside cylinder is about the position of greatest effort. On eight-coupled engines with three-cylinders the effect may be quite marked and in some cases the coupling-rod main crank bearings may exhibit excessive wear evidently caused by the extreme stresses set up at that point, and' this is not surprising as considerably over three-quarters of the total tractive effort of the engine may be transmitted through it at certain positions. It is even correct to say that· coupling-rod pins of inside cylindered two-cylinder locomotives should theoretically be set with an allowance for any inclination there may be of the cylinders to the horizontal—as was referred to by ·the writer as far back as 1917 (Locomotive Vo!. 23, p. 128).
In the article reference is made to the difference in the arrangement of the wheel-balancing brought about by adjusting the inside crank to the proper angle, but this merely causes some modification in the balance calculations although it does mean some—usually very slight-difference in patterns. between the wheel-centres of the respective sides of the locomotive,

The second section of the new line from Motspur Park to Chessington South was opened on 28 May with three electric trains an hour to and from Waterloo and a journey time of 31 minutes. This new line is laid for the most part on embankments and through cuttings, the embankments being completed with dry filling material obtained from slum clearance and demolition works in London. No less than eleven bridges over and under the railway have been constructed with steel girders completely encased in concrete. New style stations of a novel type built in reinforced concrete work and giving unobstructed platforms free of columns, the platform roofs supporting themselves between cantilevers, have been provided. The illumination of the platforms is by means of fluoroscent tubes.

Institution of Mining Engineers.
On  30 June members of the Institution visited the East Hecla Works of. Hadfields Ltd.— the foremost manufacturers of colliery requisites, whose comprehensive facilities, enable them to supply and often to anticipate the needs of those engaged in the business of mining and quarrying. They have the resources of a steel plant equipped to make steels by all the modern processes, and comprehensive foundries, rolling mill and forging shops on a large scale. This firm holds an unrivalled reputation as manufacturers of wheels and axles, their producbionbeing the largest in the world. Hadfield's Best Toughened Cast Steel—or where the working conditions are particularly severe Hadfield's Patent" Era" Manganese Steel—are both used for the wheels, which are fitted to the axles by the Hadfield "Lockfast" system, by which l risk of their worloing loose in service is eliminated. When users prefer the wheels to run loose on the axles, the Rowbotham Self-Oiling type is recommended. These are made in the same high grade of cast steel as the fast wheels. Considerably less haulage power is needed when tubs are equipped with these wheels, whilst there is also less danger of the tubs becoming derailed on sharp curves. Wheels and pedestals fitted with roller or ball bearings are also available and can be supplied when desired. Hadfields make a variety of tubs, of both wood and steel type, for use under different conditions. Special mention can be made of their "Hecla" Dustproof Tub, which is built of steel. plates, embodying horizontal corrugations and an upper rim of adequate proportions and strength ; it can readily be taken to pieces and re-assembled with equal facility after the necessary repairs have been effected. Every part of the tub is made to template and interchangeable, and should any component become damaged beyond repair a new part can quick- ly be fitted. Another feature of the tub is that it can easily be dismantled and packed in small compass for transportation.

In connection with the London Spring Meeting of the Institution, some of the members visited the Fraser and Chalmers Works of the G. E.C., at Erith. On arrival the party, which included H. L. Guy, F.R.S. (Vice-President) and Major Willriam Gregson, M.Sc., and Mr. Tarns, M.Sc. Tech. (Members of the Council), was received bv Messrs. F. Lonsdale and E. A. Pitcher, the Joint General Managers, and proceeded on a tour of inspection of the various shops. Special interest was taken in the turbine shop where a 20,000 k W, 3,000-r.p.m. G.E.C.-Fraser and Chalmers turbo-alternator set for Darlington Corporation was seen completed and ready for test. Other machines under construction included 30,000-kW turbines for various municipalities in this country and a 37,500 kW turbine for Orlando Power Station, Johannesburg.

L.lN.E.R. suburban extensions. 214
In connection with the electrification of the London and North Eastern suburban lines from Liverpool Street and Fenchurch Street to Shenfield, an important contract had been placed with the General Electric Co. Ltd. covering plant and switchgear to be installed in six sub-stations and three sectionalising track cabins. The equipment (except for the supervisory control equipment and the high tension switch gear for two sub-stations) to be manufactured at the Witton Engineering Works of the G.E.C. and included 14 twin-cylinder air-cooled steel-clad rectifiers complete with main 33,000-volt transformers, each rectifying equipment being rated at 2,000 kW 1,500 volts, D.C.; switch- gear for controlling the 33,000-volt incoming supply, this including 10 metalclad units (all of 500,000 kVA breaking capacity); and approximately 77 high speed circuit breakers, 1,500 volts D.C. A feature of particular interest is that the rectifiers are the first air-cooled steelclad units to be supplied for service at 1,500 volts.

Pacific Locomotive Committee Report. 215
The Report of the Committee appointed in July 1938 to inquire into the design, operation, general suitability, etc., of the XA, XB, and XC classes ef Pacific locomotives in use on the railways of India had been published by the Government of India and was devoted to findings on the administrative side as well as those on the technical. This Committee consisted of Lieut-Colonel A.H.L. Mount, Chief Inspecting Officer of Railways, Ministry of Transport, who was the Chairman; . R. Carpmael, Chief Engineer (Civil), Great Western Railway; Rai Bahadur P. L. Dhawan, former Chief Engineer (Civil), North-Western Railway of India; R. Leguille, Regional Chief 'Mechanical Engineer, French National Railways; and W.A. Stanier, Chief Mechanical Engineer, London, Midland and Scottish Railway.
As was to be anticipated with such a galaxy of talent available, the Report is most far-reaching and informative, constituting not only an exhaustive treatise on the particular engines concerned but also containing' a wealth of information on locomotive design and operation, much of which is applicable to main line locomotives the world over.
The reason which led up to the introduction of locomotives of the Pacific type in India was the rise in the cost of first-grade coal resulting from the Great War. Supplies of second-grade fuel were available over wide areas, including from collieries which had been acquired bv the Railway Board, but to use this fuel satisfactorily wide fireboxes were considered essential, practically necessitating the 4-6-2 wheel arrangement.
The Report, which is well indexed and clearly illustrated by diagrams, begins by referring to the general aspects of the problem and proceeds to trace the history of this type of engine in India. It would appear from the summary of performance included in the last-mentioned section that these engines gave considerable trouble in other directions than derailments, although it was the derailment at Bihta in July 1937 that led to the investigation. The 284 engines concerned covered a total of 90 million miles up to the end of March 1938 and during this period there were no less- than 347 frame fractures and 205 firebox tube plates had to be changed due to cracks in the- radius. On the E.B.R., where 18 "XB" locomotives were in use, it appears that the average time-spent in the shops under repair was three years out of a total average life of eight years, viz., 37 per cent. of their time.
The next feature of the report consists of a chapter on the disturbing forces in a locomotive and its characteristic movement on the track. This we consider to be such an important contribution to the published matter on the subject that we are including extracts from it elsewhere in this issue. Permanent way is the next point to be dealt with, this in a country such as India where the grade of labour available is not of as high a standard as is desirable and where extreme climatic conditions and unsatisfactory sub-forma- tion are apt to be encountered, is most difficult to' adequately maintain, although many miles of excellently laid and maintained track exist in various parts of the country.
Some people perusing this report may consider a few of the opinions expressed on the relation ot the engine to the permanent way to be axiomatic. but the points mentioned are all ones that while heing fundamental are apt on occasion to be overlooked. As is pointed out, the most important consideration in the investigation of the performance of a locomotive as a vehicle, and of the track upon which it runs, is that they are in effect two parts of the same machine. The essential feature of an engine in this respect is that it should run smoothly and steadily, subjecting the track to a minimum of stress at the highest designed speed. Substantial and well maintained track may mask the lateral instability of a locomotive. so that it may appear to be a good riding engine. and yet it may prove unsatisfactory when running- on weaker track or over more yielding formation. Footplate experience, Hallade records and engine maintenance receive due consideration together with research and development; these latter are not confined to Indian praotice but include work carried out abroad.
The suitability, conditions subject to which these engines can safely be used and possible modifications form subjects of additional chapters leading up to the Committee's concluding remarks. See also 222

New South Wales Govt. Railways. New trains for inter-city services. 218. illustration
The N.S.W. Government Railways placed two new train sets on the Sydney-Newcastle Inter-City services—the third replacement of equipment since the Inter-City Express and the Newcastle (formerly Northern Commercial Limited) Express trains were instituted in 1929. The new trains each consist of five cars, converted at Eveleigh Workshops from former main line MCX oomposite and MFX second-class corridor cars, measuring 74 ft. 4 in. over buffers and carried on six-wheel trucks with loop brakes. The regular set consists of four cars which tare 180 tons, with one spare car for each set. The seating capacity of 228 passengers made up of 72 first-class and 156 second-class.
The exterior colour-scheme of bright red with windows and pillars of cream has been perpetuated and the interior of each car has been extensively re-arranged to provide for open sitting saloons and some enclosed compartments. In the first-class cars the saloons are equipped with movable lounge type chairs made of chromium plated tubular steel and upholstered in blue leather. The seats are adjustable. Seats in second-class are fixed and upholstered with maroon enamelled leather. Removable tables are provided in all cars and all metal fittings are chromium plated. A feature of the interior decoration is the panelling of beautiful native timbers.
Each train has an efficient buffet service and push-buttons to summon the attendants are installed in the car walls near the seats. Attention has been paid to the lighting of these trains which carry a large number of business men who often require to read while travelling. Ventilation is provided by means of ceiling extractors and there are electric ceiling fans in first-class saloons and bracket fans in other compartments.
The attached photograph shows one of the new train sets. The handsome exterior appearance of the cars can be seen and the train is hauled by engine No. 3609, a heavy 4-6-0 passenger locomotive of class C36. Like many of the other 74 locomotives in the class, No. 3609 is painted in the striking green livery of the N.S.W.G.R., lined in red, yellow and black.

Continued from page 165). Tayleur & Co. of the Vulean Foundry, Newton-le-Willows, also built two single driver tender engines in 1849, which were numbered 3 and 4 (Makers' Nos. 321-2). No. 3 carried the name Faugh-a-Ballagh, which signifies in English, "Clear the way." They had 5 ft. 6 in. driving wheels, and 3 ft. 6 in. leading and trailing wheels, the latter being interchangeable with the tender wheels. The inside cylinders were 14 in. diameter by 20 in. stro e, with the valve motion outside. The engines had brass domes and handrails, and weather boards were added about 1860. They weighed 20 tons each empty, and were in service until about 1890. (Fig. 5). Early in 1850 some interesting trials were made in order to test the comparative merits of the Bridges Adams "Light" locomotives with the heavier Tayleur engines. Several trips were made be- tween Bandon and Ballinhassig, a distance of 9¾ miles, on an ascenting gradient varying from 1 in 176 to 1 in 100, the latter having a continuous length of two miles. The Tayleur engines with five carriages laden with 50 passengers, a total load of about 50 tons, performed the journey in 16 minutes 45 seconds, or an average speed of 35 m.p.h., and consumed while running 25¾i lb. of coke per mile. The return trip to Bandon occupied 15 minutes 45 seconds, or an average of 38 m.p.h.
One of the Adams engines with 30 tons behind it, performed the journey to Ballinhassig in 22 minutes, or an average speed of 26t m.p.h., and consumed 13 lb. of coke per mile. The return to Bandon took 17 minutes 22 seconds, or an average of 33½ m.p.h. A heavier train of eight carriages, equal to a load of 68! tons, was taken up to Ballinhassig by a Tayleur engine in 29 mins. 36 secs., an average of 29 m.p.h., on a coke consump- tion of 34t lb. per mile.
For working goods traffic two 0-4-2 tender engines were delivered by Sharp Bros. of Manchester, in August 1852, makers' numbers 698-9. These became Nos. 5 and 6, C. & B. Ry., and had cylinders 16 in. diameter by 22 in. stroke; the coupled wheels were 5 it. and the trailing 3 ft. diameter. The cylinders, which were inclined 1 in 11, were of rather peculiar design, having the steam chests placed under and between the cylin- ders, the valve faces being inclined. It will be noticed that the coupling rods were of the old circular section. The boiler had its centre line 6 ft 3 in. above rail level ; its diameter inside was 3 ft., and length 10 ft. 2 in.; there were 161 2-in. tubes giving a heating surface of 873 sq. ft., whilst the firebox contributed a further 71 sq. ft., a total of 944 sq. ft. The buffer height of the Cork and Bandon stock at this period was only 2 ft. 8 in. The tenders were carried on four wheels, 3 ft. 6 in. diameter, and contained 850 gallons of water. No. 5 engine was running until about 1887, but No. 6 was replaced in 1881. (Fig. 6).
The next. engine purchased was a 0-4-0 saddle tank built by Fairbairn & Sons in 1862; it was numbered 7, and is understood to have been for working the Kinsale Branch, which had many sharp curves; the inside cylinders were 14 in. by 22 in. and the coupled wheels 4 ft. 6 in. diameter. This engine lasted until 1901 when it was completely renewed at the Cork works, in fact the latter No. 7 was practically a new engine, though a few parts of the old locomotive were used. As rebuilt it was a 4-4-0 side tank; the boiler was a spare one from Dubs & Co. similar to those on the 2-4-0 side tank class built by that firm, which will be referred to later, and in other respeots, except for the leading bogie, the rebuilt engine was very similar to the 2-4-0T class. The cylinders were 15 in. by 22 in., coupled wheels 5 ft. and bogie wheels 2 ft. 6 in. diameter, heating surface 857 sq. ft. (tubes) plus 77 sq. ft. (firebox), a total of 934 sq. ft. The tanks held 750 gallons, and the cost of the engine is stated to have been £1,500. Later a standard boiler with 143 tubes was substituted having a heating surface of 726 sq. ft.
(tubes), plus 75.5 (firebox), a total of 801.1) sq. ft. This engine became No. 478, Great Southern Rys. in 1925, being classi ed D 18 ; it was scrapped in 1935. (Fig. 7).
The following three ngines were purchased second hand from the Great Southern and Western Ry., two of them replacing the Adams "Light" engines, which had been withdrawn in 1868. The first of these was a 0-4-2 goods tender locomotive that had been No. 103, G.S. & W.R., and was built by Bury, Curtis and Kennedy in 1848. It was of the well known Bury design with bar frames and haystack firebox, and had cylin- ders 16 in. by 24 in. The coupled wheels were 5 ft. diameter, and the trailing wheels 3 ft. The wheelbase was 8 ft. plus 5 ft. 1 in., a total of 13 ft. 1 in.; the original boiler was 3 ft. 7 in. dia. by 11 ft. I½ in. long. This engine came to Cork in 1869, and was numbered 1 in the C. and B. Ry. list. (Fig. 8).
The second engine was purchased in 1871 and became No. 2. It had been G.S. & W.R. No. 38, a Bury single built in 1847 with cylinders 14 in. by 20 in., and driving wheels 5 ft. 8 in. diameter. The other dimensions of this class as built were: Leading wheels, 4 ft. 2 in., trailing wheels 3 ft. 8 in., wheelbase 6 ft. 11 in., plus 6 ft. 2½ in., total 13 ft. 1½ in. Boiler 3 ft. 8 in. diam. by 10 ft. 5½ in. long; 119 tubes of 21/8 in. diameter. Weight of engine about 19! tons; tender on four wheels holding 1,344 gallons. (Fig. 9) . A year later a second engine of the same class was added to the stock, becoming No. 8 C. and B Ry. This engine had been No. 24 G.S. &  W.R. Rly., and was built by Bury in 1847. It was stated to have had 6 ft. driving wheels.
All these three engines were very old, and worked at 70 lb. pressure. No. 8 in particular gave a lot of trouble. On 31 October 1873, she was derailed near the Ballinhassig tunnel. On 14 November the valve spindle broke, and on the 18th the steam pipe of the same engine burst. About this time the Cork and Bandon rolling stock was, according to a Board of Trade report, in a very poor state of repair. Out of eight engines only four were employed in running trains, three required repaumg, and one was used for shunting only. There was a difference of nine inches in the level of the buffers of some of the wagons, and m many cases marks of buffers having mounted could be seen, so no wonder derailments were so frequent.
Single driver engines were hardly suitable for the Cork and Bandon line with its heavy gradients, so No. 2 was rebuilt at Cork as a 2-4-0 engine with 5 ft. 6 in. coupled wheels, and 4 ft. leading wheels. (Fig. 10). However, it soon became necessary to replace these three engines which did little work on the C. and B. Rly. ' In 1874, Messrs. Dubs & Co. built the first of a new 2-4-0 side tank class, that may be said to : have remained the standard for passenger work until 1891; the makers' No. was 760, and the Cork and Bandon No. 1; the cost was £2,335. The dimensions were—Cylinders 15 in. by 22 in; coupled wheels 5 ft. and leading wheels 3 ft. 6 in. diameter; wheelbase 13 ft. 4 in. equally divided; 143 tubes; heating surface 726 (tubes) plus 75.5 (firebox), total 801.5 sq. ft. Tanks 500 gallons (later enlarged to 750 gallons), weight in working order, 12 tons 15 cwt., 13 tons 19 cwt., and 10 tons 10 cwt.; total 37 tons 4 cwt. (Fig. 11).
A similar engine, No. 2, followed in July 1875,. makers' No. 861, and cost £2,100. Both these engines had brass dome covers on the second boiler ring, with spring balance safety valves on top, which were later replaced by pop valves. No. 2 was rebuilt at Cork in December 1908 with a lead- ing bogie having wheels 2 ft. 6 in. diameter, and in this condition was similar to No. 7 already referred to; both Nos. 1 and 2 passed over to the G.S. Rys. in 1925, No. 1 being re-numbered 482 and classed "G6", and No. 2 becoming 477 with classification "D 18"; they were withdrawn from service in 1 930.
A third engine of this class, No. .8, makers' No. 1072, was supplied by Dubs & Co. in 1877. It differed from the first two in a few details, notably in having a plain dome and separate Ramsbottom valves over the firebox; this engme was replaced in 1920.

L.M.S.R: Scottish centenary. 234
The first section of the Glasgow, Paisley, Kilmarnock and Ayr, as between Ayr and Irvine, eleven miles, was opened on 5 August 1839. The line was the L.M.S. Railway between Glasgow and the Ayrshire coast and opened throughout in 1840. The Glasgow. Paisley. Kilmarnock and Ayr Railway was also linked with the first railway in Scotland. which it absorbed in 1846. This was a tramway constructed by the Duke of Portland for the conveyance of coal from collieries in the Kilmarnock area to the port of Troon: it was opened in 181I and at holiday times passengers were conveyed in horse-drawn trams. It was on this line that one of the earliest experiments was made in the use of locomotives in Scotland.

Locomotives at the World's Fair. 234-5. illustration
The railroads' exhibit at the New York Warld's Fair, in the words of the official description, is intended. "to do full tribute to the American Railroad". It would appear that this endeavour has been amply fulfilled as the exhibits which have been prepared by the Eastern Presidents' Conference are both extensive and of great interest, constituting one of the largest collections of early and modern locomotives ever assembled, and well illustrating the development of the locomotive aver the last 110 years.
In the space at our disposal it is impassible to describe the many engines an show but in some instances these have already been illustrated and described in the LOCOII'IOTIVE; in other cases descnptions will he appearing in forthcoming issues. Same idea of the size of the exhibit may be gathered from the fact that it covers 17 acres and results from the co-operation of twenty-seven railroads.
An elaborate Pageant-Drama of Transport is presented and forcibly canveys the enarmaus progress since the Stourbridge Lion first made its appearance in 1829. Amang the many other engines either included in the pageant or an view in what is styled "The Yard", may be mentioned Tom Thumb (1829), Best Friend (1830), John Bull (1831), Atlantic (1832), Wm. Galloway (1837), General (1855), Thatcher Perkins (1863), which, in conjunction wi~h many others lead by engines representmg varying stages of development, such as the Union Pacific Pride of the Prairies (1882), to the well knawn New York Central No. 999 and thence to the present time.
In the case of same of the engines mentioned, as the original is no longer extant a replica is utilised, the reproductions being excellent. Exhibits are not confined to large locomotives, small ones being also included ; a good example of the latter is the Northern Pacific Minnetonka (1869) . Amang the modern locomotives probably the mast autstanding is the Pennsylvanian 6-4-4-6 engine, rated at 6,500 h.p., briefly described in our May issue; other modern examples are the 4-6-4 locomotives of the Lackawanna, New York Central and New Haven Railroads, and an engine of this wheel arrangement sent by the Canadian Pacific Railway. The Canadian National Railways are represented by a 4-8-4 type.
Many of the modern engines changed durmg the course of the Fair, their place being taken by others representative of the latest practice. Complete trams were also an view, including, of course, the L.M.S. Coronation. Scot and a three-coach electric train from Italy reputed to have a sustained speed of 120 m.p.h. Included in the most interesting items must oe mentioned the collection of prints and models arranged by the Railway and Locomotive Historical Society.
A point apparent in early American practice is the extent to which the vertical boiler was used, no less than five of the engines exhibited being so equipped; these include the Pep persauce (1869), the first locomotive to be constructed for the rack-railway up Mount Washington.
The operation of railways is depicted by avery large model containing no less than 3,800 ft. .if track and worked by 50 locomotives and 400 cars. This is situated in an auditorium capable of seating one thousand spectators who witness a performance lasting forty minutes which shows an average days' work on a representative road. It is refreshing in these days when so much is heard of the replacement of the steam locomotive by other forms of prime mover to be able to record the impression formed by the locomotives gathered together. A study of these leads one to conclude that so much development has been made in the last few years, and is still being made, that it may well be considered that the steam locomotive still has the best part of its life before it

Two further streamlined 4-6-2s of the Princess Coronation class had left the Crewe shops, Nos. 6236 City of Bradford, and 6237 City of Bristol. The next two had also been completed and were the paint shop. The following additional superheated 0-8-0s of G1 class had been converted to class G2A Nos. 9022, 9078, 9150, 9192, and 9228. These engines, formerly power class 6, were now designated power class 7. As now running they are all fitted with standard Belpaire boilers. Engines recently withdrawn from traffic at Crewe included 4-4-0s Nos. 25279 Sunbeam, and 25310 Thunderer (both of the superheated "Precursor" class), and 0-8-2 shunting tank No. 7890. Two further 0-6-0 heavy oil locomotives have been completed and turned out at Derby, Nos. 7086-7. The latest standard 0-6-0 in traffic is No. 4586. Recent withdrawals at Derby included one of the few remaining 2-4-0 tender engines, No. 20194. Two of the 4-6-2 express engines were stationed at Longsight for working the Mancunian, Lancastrian and Comet expresses. The loads would be increased when necessary. The maximum load for the Royal Scot class was 415 tons. We recently travelled on one of these trains and No. 6206 Princess Marie Louise--one of the transferred engines-easily kept exact time on the difficult 92 minute non-stop schedule, Nuneaton-Euston (97 miles) with nearly 500 tons behind the tender.

Steam locomotive development. 243.
If it ever comes to pass—and we doubt if such a thing is possible—that the steam locomotive be replaced by some other form of prime mover, historians will at least record that it did not disappear until every reasonable line of development had been explored.
A study of our pages over the last few years will show the amount of research, thought and finance which has been expended with a view to :mcreasmg the earning capacity of the orthodox locomotive, and although one might be excused for concluding that this has in some cases nearly attained its optimum, it is as well to remember that this opinion has always been held by some since the early days of locomotives and has repeatedly turned out to be erroneous. It is however reasonable to assume that the non-articulated reciprocatimg locomotive, fitted with an orthodox boiler as 'represented by' some of the latest examples, has reached a position where no great improvement in efficiency can be looked for either thermally or mechanically.
This view is supported by the fact that many of the more recent experimental locomotives have departed from the conventional either in the manner in which steam is generated or utilised or both. An .example in the last category is the Union Pacific 5,000 h.p. locomotive recently described The Locomotive , and by no means the least mterestmg feature of this engine is the use of a closed steam circuit enabling less than 100 gallons of water to be carried in the boiler. Obviously the great benefit to be derived from this is the rapidity with which steam can be raised from cold, removing one of the chief objectrons to the steam locomotIve when compared with other forms of prime mover.
Another boiler capable of rapid steam raising is the Velox, which can produce 290 lb. per sq. in. within 15 minutes from cold. This boiler utilises pressure combustion of oil or gas and it is interestmg .to note that, whereas, under given tests the efficiency of the ordinary locomotive boiler has proved to be from 65 per cent. to 75 per cent. the Velox boiler under similar conditions has produced efficiencies of between 83 per cent. and 86 per cent. High steam pressures with their attendant advantages are still finding favour in some quarters although long experience has convinced others that for locomotive purposes the disadvantages outweigh the gains, Whether this is so is largely dependent on the type and general constructional details of the boiler employed and the quality of the feed water available. In the latter connection as readers will be aware some railways now prefer to carry large supplies of treated wa.ter in the tender rather than rely on water obtained at a number of points en route as was previously the practice .
Among recent high-pressure locomotives we may mention one for the French National Rai1ways; this burns coal m a water-tube boiler which operates at 879 lb. per sq. in.; motive power is derived from six three-cylinder engines driving the axles through geanng. At full output this engine develops 3,000 h.p.
Another engine from which much valuable information should be obtained is that built by Schneiders also for the French National Railways; in this case an orthodox locomotive boiler constructed of high-tensile steel supplies steam at 365 lb. per sq. in. to a turbine mounted on each axle. The examples quoted are selected at random and represent but a few of the many attempts at present bemg made to produce a locomotive which shall be of equal reliability to the present machine and shall exceed.It from the profit earning aspect. Although nothmg worth while was ever achieved without effort and much outlay has been necessary to bnng some of the most beneficial of inventions to their present state of perfection, there does nevertheless appear to be a tendency for experiments aiming to achieve the same result by identical. means to be carried on simultaneously, The poolmg of resources under such conditions could not fail to result in substantial financial savings and technical gains, but the idea is no doubt too Utopian for the present time. It is, however, worth recalling that the enormous strides made by the internal combustion engine in the years 1914-1918 were largely due to the policy of concentrating and co-ordinating all the available talent on the subject in contra;tst to the independent and over-lappmg efforts which had previously persisted.

The Joint Select Committee appointed by the Norfhern Ireland Parliament made some far-reaching recommendations, among which is that the special task of enforcing the duties upon the Transport Board and the railways of providing a properly co-ordinated system, should be a function of the Government, with a Minister directly responsible to Parliament. A merger of road and rail interests should be deferred until a co-ordinated system had been achieved, and the closing of all but some main line railways was foreshadowed.

Auto-electric model railways. A. Duncan Stubbs. London: Thomas Nelson & Sons, Ltd.
The author describes the various methods of electrifying model railways and then deals in considerable detail with control systems. Remote and automatic control are fully explained and clearly illustrated; a chapter is also included on the radio control of model boats. This book should prove of considerable use to those interested in the subjects covered.

Speeding North with the "Royal Scot." Driver L. A. Earl. The Oxford University Press,
Although nominally written by a driver of the L.M. & S. Railway, there can be little doubt that this book has had the approval of the officials of that company. Nevertheless Driver Earl, who is no doubt well known to many readers of this journal, gives a very interesting account of a day in his life, which includes a trip from London to Carlisle with the "Royal Scot." Driver Earl calls attention to many incidents and happenings on the journey which would probably occur to no one but the man in charge and therefore gives a view of the work on the footplate from a somewhat different angle from that from which it is usually described. The preparation of the engine before the journey, the proceedings at the Hostel at the end of the trip and a general talk on railway doings help to complete the driver's survey of the locomotive man's calling.
The book is well illustrated with many excellent half tone blocks, and contains lists of both standard and non standard classes of L.M. & S. locomotives bearing names. Finally there is an interesting diagram, covering 16 pages, of the line from Euston to Carlisle, which will be very helpful to readers wishing to pick out the many and varied objects seen from the carriage window.

L.N.E.R. Bank Top shed bell. 269
The old bell from the dismantled Bank Top Loco. Shed had been acquired by the Rector of Haughton-le-Skerne for his church hall in which services will be held until a new Parish Church can be built. Made hy S. Thompson of Darlington in 1841 it was originallv hung as a time bell at the Great North of England Railway Carriage and Harness Shops. This company was later merged into the North Eastern Railway, a constituent of the L.N.E.R.

In 1922 the K class 2-8-0 was introduced for mixed traffic use on light lines: they had 20 x 26 in cylinders, 1728 ft2 total heating surface (including superheater), 20¾ ft2 grate area and 175 psi boiler pressure. The N class 2-8-2 was introduced in 1931 for working light lines: total heating surface 2274 ft2, grate area 31 ft2. One locomotive, No. 110, had been fitted with a booster (illustrated). The X class was introduced in 1929: this was described in the May Issue of 1929. The boiler pressure increased to 205 psi.

Fayle, H. The Cork, Bandon and South Coast Rly. and its locomotives. 275-7. 5 illustrations, 3 diagrams (side elevations)
In 1880 the West Cork Railway was purchased. It had three locomotives: two 2-4-0T supplied by Cross & Co. of the Sutton Engine Works in St. Helens WN 17 & 18/1865. These had 15 x 22 inch outside cylinders and 5 ft 6 in coupled wheels. They were named Patience and Perseverance. The drawing was supplied by M.J. Reen who was the last locomotive superintendent of the Cork & Macroom Railway. Another 2-4-0T came from the Vulcan Foundry WN 806/1877: this came via the Ilen Valley Railway which linked Dunmanway with Skibbereen: it had 15 x 20 inch cylinders and 5 ft coupled wheels. The West Cork livery was olive greeen. The locomotive superintendent was Johnstone who was followed by his son, J.W. Johnstone who took over the Cork & Bandon post.
In 1891 the first of a new class of 4-4-0 passenger tank engines was built by Dubs and Co., makers' No. 2777; it replaced old No. 3, and had the following dimensions: cylinders 16 in. by 22 in., coupled wheels 5 ft. 6 in., bogie wheels 3 ft., wheelbase 5 ft. 3 in. plus 6 ft. 5! in., plus 7 ft. 3 in., total 18 ft. 11! in., the boiler had 143 tubes of li in. providing a heating surface of 765.5 sq. ft., and the firebox added 86 sq. ft., the total heating surface being 842.5 sq. ft.; the side tanks held 750 gallons; the maximum axle load was 15 tons 1 cwt., and the total weight in working order 40 tons 9 cwt.; the cost was £2,100. The tank and bunker capacity proving insufficient the engine was rebuilt at Cork in December 1901 with a larger bunker and trailing radial axle the wheels of which were 3 ft. 6 in. diameter; the total wheel- base was increased by 6 ft. 11 in. to 25 ft. 10t in., the tank capacity being 1,000 gallons, arid the weight on the axles, 13 tons (on bogie), 14 tons, 14 tons, and 10 tons, a total weight in working order of 51 tons. This engine became No. 479 G .S. Rys. in 1925, being classed "C 6", and was scrapped in 1930. (Fig. 19). A second engine of the same type was delivered by Dubs . in July, 1893, makers' No. 3048, and replaced old No. 10. The dimensions were mostly similar and the cost was £ 1,845; the heat ing surface of this engine was 751 (tubes) plus 80 (firebox), a total of 831 sq. ft. In June 1906 it was rebuilt at Cork with a larger bunker, but in this case an additional trailing coupled axle was added, the arrangement becoming 4-6-0, its appearance being very similar to the new No. 11 engine that will be alluded to later. The wheel- base was increased 'by 6 ft. 3 in. to a total of 25 ft. 3t in., the tank capacity was 1,000 gallons, and the weights on the axles were: 13 tons (bogie), 13 tons 10 cwt., 13 tons 10 cwt., and 11 tons, a total weight in working order of 51 tons. This engine became No. 471 G.S. Rys. in 1925, being classed "B 5", and was scrapped in 1933. (To be continued).

Rack-rail diesel-electric locomotive. 277.
The first Diesel-electric locomotive for a rack railway has recently been delivered by the General Electric Co. (Schenectady) to the Manitou and Pike's Peak Mountain Railway which for the past half century has been worked by steam rack locomotives.

Ambulance trains 277
The British railways are building a number of Ambulance Trains for use both at home and overseas. Each of the trains is fully equipped with cars for travelling staffs of nurses and doctors, kitchens, and wards. Cars are also provided for infectious cases and as travelling pharmacies. Trains have also been built for immediate use in the event of casualties occurring as a result of air raids in order to assist in the distribution of injured civilians to hospitals throughout the country. The fitting up of the trains includes electric lighting, steam heating and numerous devices are incorporated by co-operation with medical authorities to ensure the comfort of patients en route. Special workings are arranged for these trains whenever required.

C.A. Branston. F.W. Webb and the brake question. 278.80.
Little visible trace remains of the designs and devices which Webb brought out and sponsored in the course of his long reign at Crewe; but there is a matter of great importance in our time, in the ultimate disposition of which his dominant personality, determination, and in- fluence were undoubtedly the deciding factor, though his name is unconnected with it, namely, the fact that the steam roads of Great Britain to- day are equipped with the vacuum brake rather than with the air brake as they are in most other countries. The narrative of the circumstances properly belongs to the history of power brakes, but it so well illustrates the curious characteristics which prompted Webb to build locomotives of which the driving wheels could and sometimes did rotate in opposite directions, that it may, not in- appropriately, be referred to here as a postscript to the article which appeared in the June number of THE LOCOMOTIVE. None of his undertakings and enthusiasms show up to better advantage his strange faculty-somewhat expensive for the shareholders-for "backing the wrong horse." To make the matter clear it is necessary however first to set out briefly the principal events which led up to the above development.
The brake question had been one to which in certain quarters-largely abroad-an increasing amount of thought had been devoted ever since George Stephenson had fitted buffer brakes-the first power brakes-to some cars on the Liverpool and Manchester Railway about 1832. In 1862 John Clark brought out a chain friction brake which was tried out on the North London Railway by W. Adams and was adopted there as the standard brake in 1863. At that time the usual brake equipment on the London and North Western Railway comprised merely a hand brake on the tender and one on the baggage car at the rear of the train. In 1863 this railway had however acquired a general licence to use the Fay brake; in this a continuous shaft, with flexible plunging joints between cars, ran along the train and was rotated by hand from the baggage car to operate the brakes collectively. This brake was fitted to the royal train and to the Irish mail trains. In 1870 the same railway also acquired a general licence to use the Clark chain friction brake of which Webb subsequently redesigned the actual rigging, converting it so 'as to employ two brake shoes per wheel-presumably the first clasp brake to come into general use. About 1874 Webb appears to have decided to equip the whole of the passenger cars of the line with this brake, and the fitting began forthwith; the following year a train of 15 cars thus equipped took part in the Newark brake trials.
In September, 1868, the Westinghouse straight air brake had been fitted for the first time to a train in regular service, and in 1872 the automatic form of this brake was arrived at. The immediate success of this brake brought into prominence two distinct features of railway brakes, viz., (i) con- tinuity, and (ii) automaticity. The first of these characteristics had been considered for a number of years, but chiefly from the point of view of economy of personnel; George Stephenson and some few others after him however realised the importance of the centralised control of all the brakes in the train more particularly with regard to safety. Automaticity, though present in more than one of the other-than-pneumatic power brake designs, either suggested or as actually construc- ted, was not appreciated, and had, in fact, been made but little of, even by the inventors of these devices, while in some cases the feature was actually abandoned on the plea of simplicity. Westinghouse was probably the first fully to ealise the paramount importance of this characteristic, and others soon acknowledged its wisdom, ith the result that in April, 1872, three and a half years after its introduction, there were over 5, 000 air rake sets in use in America alone; by April, 1874, the number had increased to over 9,000, and in 1876 to over 11,000.
A few details of the Clark and Webb chain friction brake and of the peculiarities of its operation must now be interposed. In this design a friction wheel in the baggage car, when engaged with a pulley fixed to one of the car axles, caused a 3/8 in. chain to be wound up which, running from car to car along the train and passing round pulleys on the brake levers there, thus brought the brake shoes up against the tyres. As the chain ran its somewhat devious course over a number of pulleys on each car, and as the slack to be wound in was considerable—well over 2 ft, per car—and increased as the number of cars, the application of several brakes in any group of cars was anything but simultaneous from this cause alone; furthermore, buffer movements interfered seriously with uniformity of action, and this, together with the behaviour of the friction gear, utterly defeated any attempt to effect a progressive or gradual application. As the chain oould not be extended properly to operate more than four or five brakes, longer trains were divided up into sections, each with its own chain and winding gear; this of course did not simplify the making up of such trains or the setting out or picking up of cars on the way. As an example of make up, the 15-car trial train at Newark comprised a baggage car with two independent sets of winding gear which controlled respectively the four passenger cars ahead of it and the four following cars, while the remaining five passenger cars were braked from a second baggage car at the tail end of the train. The several winding gears in a train were started individually by hand by the attendant brakemen or guards, but at Newark and, at a later date, in general service, this could also be effected collectively by means of a cord running to the footplate Engines. tenders and baggage cars were not provided with this brake. In an application the stress on the chain amounted to about 1,600 lb., and a rupture of course rendered all the connected brakes inoperative.
With a powerful but erratic brake such as this, simultaneity of action was of more than usual importance—particularly where the train was composed of several sections—not only for the comfort of the passengers, but also for the safety of the train. Those who remember the futile "communication cord" of forty years ago will readily understand that a simultaneous application of several independent groups of brakes, emanating from the footplate, was in practice excluded; furthermore, as the brake was fitted neither to the engine nor to the tender, any unexpected application, initiated on one or more of the sections of the train woulrl. therefore cast upon the latter the duty of retarding the wholly unbraked locomo- tive of which the throttle would, at the time, still be open. This tended to throw stresses on the none too robust screw-link couplings which not infrequently led to disaster; on one such occasion, when the train parted in consequence of such an accidental application, one of the. drawbars, 9 ft. 8 in. long and 1¼ in. in diameter, was found to have stretched 7¼ in., while the others had stretched to a considerable extent also. In the Newark trials the second run of the trial train similarly resulted in a brake-i - wo between the seventh and eighth cars. Some of the other disadvantages of this brake were that the friction wheels frequently required to be retrued, and in winter snow and ice tended to interfer seriously with the pulleys and chain as well with the action of the friction gear.
This then was the brake with which Webb set himself to equip the whole of his passenger cars, in spite of the all-round superiority of the Westinghouse air brake as demonstrated under identical conditions at Newark, and in the face of the satisfactory functioning of some 10,000 air brake sets which were then already in daily use in America. Webb's views with regard to brakes were, in fact, both peculiar and, needless to say, emphatic. He disapproved strongly of the air brake as being too complicated ; yet the engine driver of the successful Westinghouse trial train at Newark had never before handled this brake, either in its automatic or non- automatic form. He objected to continuous brakes as the ordinary means of stopping, neither would he allow their control to be vested in the engine driver, as he considered that the latter would enter stations at excessive speeds, unduly relying on the greater stopping power thus made available. Accordingly the chain friction brake was to be controlled by the brakeman or guard, and was employed as an emergency brake only, except in the case of the first service stop of the day's run, where it was applied to test its condition; all subsequent stops were therefore of necessity effected by means of the usual two hand brakes only. Webb would not fit a brake to his locomotives other than a hand brake on the tender, and stated explicitly that he would rather reverse the motion—which he admitted was a dangerous practice—than apply brakes to the driving wheels; though he subsequently fitted steam brakes to some of his engines, it was not until 1891 that the Board of Trade, under powers given them by an Act of 1889, were able to compel him for the first time to fit continuous brakes to his locomotives.
As has been stated above, the original Clark chain friction brake was in regular use on the North London Railway, and when Webb re- designed the brake for use on the London & North Western Railway, the same improvements were effected on the former line in 1874. That the brake worked not unsatisfactorily there is easily accounted for: the unit trains running over this suburban system were rarely broken up, and from the nature of their runs—a shuttle service—the brake gear was naturally under closer and more constant supervision; the use of a single central buffer reduced the play between cars from 22 in. to 6 in. and the slack in the chain correspondingly; the brake was used in all service stops, the frequency of which called for prompt and energetic brake action, more nearly approaching emergency applications, which was exactly the normal action of the brake; at the same time the locomotives were equipped with an hydraulic brake which was always used in conjunction with the chain friction brake.
That Webb was not unaware of the defects of this brake would appear from the fact that in 1880, in collaboration with Park of the North London Railway, he redesigned the Clark brake in an attempt to make it more nearly automatic; this however involved an additional cord or chain running along the train, besides a good deal of complication in the mechanism which would have been still more unsuited for main line traffic; it came into use on the North London Railway however.
In the meantime the fitting of the Clark and Webb brake on the London and North Western Railway progressed uninterruptedly, but Webb nevertheless appears to have seen the writing on the wall and to have realised that even he, fully backed as he was by the equally autocratic Moon, would ultimately be unable to justify and maintain this amazing contraption. That, sooner or later, he might be brought to bay by his pet aversion, the air brake, must have been gall and wormwood to him, and like a good strategist he set to work energetically to prevent "encirclement" by creating a block of railway systems which were pledged to adopt a brake of his own approval. With this object in view Webb in the spring of 1881 accordingly invited the locomotive superintendents of eleven railway systems to a conference at Euston, ostensibly for the purpose of discussing the subject of continuous brakes in connection with traffic interchange. It is significant, however, that all the railway systems thus represented either then had already definitely adopted the vacuum brake, or else were still "sitting on the fence" and were trying out this brake against the air brake. The result of the conference was, of course, a foregone conclusion; the members unanimously agreed in principle to adopt the vacuum brake, but at some unspecifi.ed future time ; rune votes were cast for the non-automatic and three for the automatic form of the brake.
That Webb's change of front did not necessarily imply a change of heart would appear from the fact that for two more years after the Euston conference he persisted imperturbably with the fittmg of the chain friction brake, increasing the number of cars so equipped by some 20 per cent. In that penod. It was not until the whole of the 6,000 cars had been thus turned out that he began to substitute a vacuum brake, a non-automatic one, and by the middle of 1887 65 per cent. of the cars had again been converted.
Before this date the use of continuous or automatic brakes had already been made compulsory m France, Holland and Prussia, while the agitation m Parliament for sImilar legislation in this country had been growing steadily ever since the Newark trials. This probably brought Webb to reahse, that once again he had "backed the wrong horse ,and in 1887 he began for the second time the conversion of his standard brake equipment, on thIs occasion to the automatic form of the vacuum .brake. By the spring of 1892 the last chain friction brake had disappeared from the London and North Western Railway, and the conversion of the non-automatic vacuum brake was completed in the same year' of the former brake a leading engineering journai once remarked: "It's whole career has been one long failure" and that may well serve as its epitaph. The "Euston " block of radways—from which only two minor systems had in the meantime seceded—thus had served the purpose for which it had been created and now accounted for some 30,500 vacuum brakes out of the total of 39,000 in use in the British Isles, the number of air brakes at the time being 19,000. To introduce on an extensive scale and on a single railway three distinct brake systems in succession within a period of fi.fteen years must surely constitute a record. But Webb had not "lost face."

Some aspects of railway progress as they affect the locomotive department, 280-2. illustration
Continued from page 240.  A note explained that had been written prior to outbreak of WW2.
Line Capacity.
Although the acceleration of passenger and freight services present separate problems and have, in the main, been the subject of individual approach and treatment, they have a community of interest inasmuch as both have a considerable reaction upon line capacity. Since the improve- ment .of passenger ser ices has to a large extent preceded that of frei ht services in this country, this inter-relation ha tended to yield difficulties when it has been nee ssary to shunt or divert important freight trains in order to provide suitable paths for quickened pa en trains. Under the dual impetus of commercia demands and operating necessities, this leeway is now being rapidly made up and the freight services in turn accelerated, so as to narrow the gap between the relative speeds of movement of the two classes of traffic, thus increasing line capacity and simplifying regulation. In the acceleration of height services, special problems arise which do not affect the running of passenger trains. An example is that of refuge accommodation for freight trains. The type of refuge siding which was formerly provided for freight trains to shunt clear of the main line and be overtaken by superior trains, involves drawing the train beyond and clear of the trailing points controlling the entrance to the lie-bye, and then setting back into it. So much time is wasted in this operation that it is nowadays the usual prac- tice to provide "running loops" entered by facing points, involving no setting-back process. There are still innumerable representatives of the older type of refuge siding in use, however; their accommodation is often limited, and this has to be borne in mind when authorising the haulage of heavier loads by new types of freight engine.
Another instance of the sort of problem peculiar to freight service acceleration is that of "station allowances." In the case of passenger trains, such allowances are almost invariably compara- tively small, and where there is no question of waiting connections, from four to five minutes is generally ample to enable passenger and parcels traffic to be unloaded and/or loaded, and for the engine(s) to be changed if necessary. (Where marshalling work has to be done or where particu- larly heavy transfers of mail, parcels or milk traffic have to be effected, the allowances natur- ally require to be rather more generous). With freight trains, however, a considerably greater latitude is required in performing work at stations and yards; not only is the rate of shunting rather slower with goods vehicles, but when locomotives have to be changed on lengthy "fitted" trains, a longer period is required for re-creating and testing the vacuum-brake-a process which on passen- ger trains is very quickly performed. In the more rapid working of freight services the layout and equipment of goods stations and marshalling yards is a factor of primary import- ance, but this specialised subject is one demanding separate attention.
So far as the actual running speeds of the faster freight trains is concerned, it is generally regarded as undesirable that freight trains com- posed of four-wheeled, short-wheelbase vehicles with mineral trains. In seeking to take advantage of the greater power of the locomotives, regard must be had to the undesirability of extending such trains beyond a certain length, especially on sections of line where the gradients are sharp and undulating, or where the block-sections are very short. Generally speaking it has not been found desirable to exceed a weight and length of equal- 85-90 four-wheeled wagons
Notwithstanding these problems, great progress has .been made by the British railways in accelerating their freight services, both of express and ordinary goods trains, by the reduction of point-to-point running times; incidentally, the use of the dynamometer car for examining the possi- bilities of acceleration is by no means confined to passenger trains, several interesting tests of this should be run at higher maximum speeds than 60 m.p.h. whether fitted with the continuous brake or not. The power of standard locomotives recently built by the British lines, such as the "Class 5" 4-6-0's of the L.M.S. and the Gresley V2 2-6-2s of the L.N .E.R., has proved such as to make it practicable in many cases both to raise the loading of the train, and to increase the average speed, provided the latter does not require the figure of 60 m.p.h. being exceeded.
Loose-C oupled Trains.
The acceleration and strengthening of loose- coupled freight trains on which the continuous brake is not in use, is another direction of im- provement in which problems exist, particularly character having been made with freight trains. Passenger Accelerations. On the passenger side, acceleration involves to a greater extent than with freight services the collaboration of such authorities as the Chief Civil Engineer and the Signal and Telegraph Engineer, but their part in the work will be referred to in future articles. The acceleration of passenger services falls into three main categories:-
1. Provision of "limited" high speed trains;
2. Acceleration of existing express trains;
3. Acceleration of branch and short-distance local services.
That more progress has been made by the United States than by Britain in the first cate gory itself gives the reason why ultra-fast, extra- fare trains of the streamlined variety have only been introduced on such a comparatively limited scale in this country. Distances between large centres of population are shorter in England, and existing ordinary services are. already fairly fast, so that there are few cases m which the luxury service can afford commercial advantages out- weighing the additional costs and line occupation involved. Moreover, it is difficult to put on trams of this character without incurring train-mileage which is wholly additional; an example of this is the mid-day service from' Euston to Carlisle and beyond, which expanded from one tram m 1~36 to three in 1939, largely through the introduction of The Coronation Scot "streamliner" service.
Britain's problem.
On long-distance routes where line occupation is relatively light and where short-distance traffic is non-existent or unimportant, as on many Amencan railroads, the introduction of ultra-fast trains can be effected with relatively little disturbance of the track-occupation as a whole. In this country, with its immense density of traffic including numerous trains which are of light formation and others which are slow-moving (such as mineral and empty wagon trains), the position is infinitely more complicated. For example, takmg the L.M.S. Western Division main line as between Crewe and Euston, over which a fair average running time for an ordinary express is 165 min. (distance 158 miles), the introduction of a tram takmg only 150 minutes will obviously have. a serious effect on the capacity of the line. It willl require the 165 minutes train(s) in front to leave earlier, be speeded up in running, or be made to follow the " flyer" (with its 15 per cent. or so faster schedule) in order to avoid delaying it; the first alternative may be undesirable commercially, the second may involve reducing the train load or providing frequent pilot assistance, whilst the third will only worsen the commercial value of the service and at the same time react upon other following trains. The fourth alternative, that the slower train be shunted at an intermediate station or be diverted fast line to slow (where both exist) for the high- speed train to overtake it, also worsens the service and introduces a precision of "control" working whose practical value is likely to be dubious. Furthermore, the ultra-fast train will leave an ever- increasing time-gap between it and any Following train run at the ordinary speed, thus agam weakening the economic occupation of the running line and conflicting with the operating theory that maximum line occupation is only obtainable by the movement of all trains of equivalent class at equivalent speed.
These difficulties are stressed, not as an argument against high-speed trains under British conditions, but rather to emphasize the variety of factors that must be weighed before such trains can be introduced and operated with a high degree of punctuality. Important considerations. also anse in regard to signalling such trams, which willl be dealt with in a subsequent article on signalling In relation to the Locomotive Department; but this also is an operating problem insofar. as there are sections of line, usually where the intervals between block-posts are short and where speeds rule high, on which in the interests of safety and general efficiency it is desirable to regulate high- speed trains by " double- block " or some other locally suitable modification of the ordinary block system. Where such modification has to be employed, the reaction on overall line-capacity is naturally adverse.
Performance both in ordinary practice and on test suggests that generally speak in the locomotives employed on British streamlined services have a reasonable margin of power available to cover such conditions as bad weather and occa- sional out-of-course slacks. On The Coronation Scot service the 6½ hours run between London and Glasgow (401} miles) is subject to a general maximum speed restriction  of 90 m.p.h. and to numerous more severe restrrctions at specified places; The Silver Jubilee and the Coronation on the other hand often produce speeds in the vicinity of 100 m.p.h. on suitable sections of line. The use on such services (and now on many ordinary "express" trains) of locomotive speed-indicators is a sine qua non in the interests of precrse time- keeping and to some extent, of safety also. All the locomotives working the "streamlined" services are, of course, so equipped.. With the engines capable of producing maximum speeds well in excess of 100 m.p.h., and of sustaining average speeds of about 70 m.p.h. almost indefinitely with a reasonable tonnage over a suitable road, the locomotive engineer has a few further problems, other than in detail of design, to take into account in connection with the opera- tion of ultra-fast passenger services. Experience suggests, however, that it is desirable if not essential that the locomotives working such services should as far as possible be kept in a special " link" of their own (consistent with economic mileage) , and should not be indiscriminately dropped into the "pool" of "big engine" turns. Thus within certain limits the further development of ultra-fast passenger services in this country would appear to be primarily a matter for the operation of the commercial, operating. and civil engineering departments, in finding (a) the need and opportunity, (b) the "paths", and (c) Suitable adjustment of the permanent way and junctions.

On 20 September 1839 the first public railway train started running from Amsterdam to Haarlem, the then Holland Railway Company, a broad gauge line of 6 ft. 4½in. gauge. To commemorate this event the Netherland Railways held an exhibition at Amsterdam in which were shown examples of rolling stock, signalling apparatus, models, etc. It was open from 8 September until 1 October at the Frederiksplein in the grounds of the burned-down Paleisvoor Volksvlijt. The exhibits included an express locomotive No. 3902 of the big 4-6-0 class at the head of a four-car train composed of a 1st class Pullman car in blue and cream livery and 1st and 2nd class sleeping cars in blue, both of the Compagnie International des Wagons lits et des Grands Express Europeens, the second car bearing the inscription in German "Internationale Eisenbahn Schlafwagen Gesellschaft." Next to this came a Mitropa dining car in crimson and at the rear a 1st, 2nd and 3rd class car of the Netherland Railways for international service in dark olive green, with partly streamlined ends and cowling between the bogies. Each car had a different destination board, showing how every part of the Continent was linked to Amsterdam by express services .. No. 3902 had its driving wheels free from the rails and turned slowly by an electric motor. The interior of the opened smokebox was illuminated at night. The photograph reproduced show the entire train. On the other side of the specially built roofed platform were standing a Diesel- dnven railcar and a streamlined three-car electric train set. .
Great interest was shown in the full size reproduction of a complete historic train of 1839 drawn by the 2-2-2 locomotive de Arend (the Eagle) running on a broad gauge track laid round the exhibition ground, departing from a facsimile of the first station at Amsterdam. Historic railway tickets of 1839 design were issued for the tour. The engine and tender were built at the Zwolle shops of the Netherland Rys., the first, second and third class carriages in the shops at Utrecht. Our second picture shows the whole train at speed. engine, with gab motion, has been fully described in Locomotive Mag. of November 1933. It was built under the personal supervision of Chief Engineer P. Labrijn, from newly prepared drawings, because the old data were found to be unreliable in several respects. It is a splendid looking machine with its polished teak boiler clothing, red brown sandwich frame and bright brass boiler mountings. The first class carriage, called diligence, is closed in with padded seats and backs, painted green externally; the second class, charsabanc, is open with padded seats only and painted yellow, the third class, waggon, is also open with wooden seats and painted brown. The names in italics are painted on the recessed doors, to designate the class.
It will not be out of place to mention that on 4 June, at the derelict station of Hoofddorp on the Haarlemmermeer railways, a film was made of this train with passengers and stage coaches and the old station, every person in historic dress to represent the departure of the train from Amsterdam.
In the exhibition grounds are further installed a piece of track with modern signals, road crossing and working signal -cabin, with a Diesel electric shunting locomotive (see tLocomotive Mag. Oct., 1932). A demonstration is also given of the Netherland Railways 5-ton containers, with specially built road auto car, which takes the container from the railway wagon by means of an ingenious compressed air driven mechanism wi th moving rail arms. It is a great pity that nothing has been done to fill the gap between 1839 and 1939. A Beyer, Peacock 2-4-0 seven feet locomotive of the 'eighties. would have been a good representative of the intermediate period.
In an adjacent building an interesting collection of early road transport vehicles has been assembled, also permanent way constructions and a good his- toric series of aluminium templates of railway trains, made by unemployed, representing trains of 1839, 1863, 1893, 1903, 1913 and 1938, each headed by a steam locomotive of the period and the Diesel and electric trainsets of recent construction. A great number of models mostly on a scale of 1 : 10 were exhibited of a 3900 express locomotive, a 6100 class 4-6-4 four-cylinder tank engine, a Borsig 2-4-0 express locomotive, Frans Hals , and several "free lance" designs, among which must be mentioned the excellent Pacific engine, on i in. scale, made by Mr. Todd of Amsterdam, illustrated in the Locomotive Mag. January 1934. .
A series of O-gauge model railways, made by unemployed, are shown representing signalling installations, electric station protection, all electrically. worked, with modern electric train sets runnmg.
Among the full size models we mention a 3900 class footplate with all fittings, a Diesel-electric control cabin, a Scharfenberg automatic coupling and a Westinghouse quick-acting compressed-air brake on a goods truck.
Much has been done for advertising the progressive policy of the Netherland Railways by means of statistics and large photographs of stations, bridges, workshops, etc. It may be said in conclusion that the Netherland Rys. give employment to no less than 30,370 people at present.

R.B. Fellows. Some early Pullman cars. 292-3
Although the Midland Railway as far back as 1874 ran for a short time a train made up partly of American cars, their own property, and partly of Pullman cars, the London, Brighton and South Coast Railway may be regarded as the pioneers in England of the all-Pullman train. This train was put into service between Victoria and Brighton on 5 December 1881, and on its way from the Pullman Palace Car Company's workshops at Derby it was inspected at St. Pancras by a representative of The route. The train was hauled by William Stroudley's Stephenson No. 329 G class 2-2-2, 6 ft. 6 in. driving wheels built at the Brighton woks in that year. On 5 December The Pullman Limited Express was put into regular service. On weekdays it left Victoria at 10.00. and 15.50, returning from Brighton at 13.20 and 17.45. The Company's time table had this note: "On and from Monday 5th December this train will consist of Pullman cars only." The 13.20 up and the 15.50 down trains ran non-stop between Brighton and Victoria, except for the then usual up ticket-platform stop at Grosvenor Road. The Sunday train ran fast on the 11 December, it left Victoria at 12.30 and returned from Brighton at 21.30 and consisted only of Pullman cars. The Times in anTimes and a detailed description was published on the 19th November of that year. The train was made up of four Pullman cars each about 58 ft. long and connected with each other by open end balconies. One of the two centre cars was provided with a buffet, the other was a' drawing- room car with a ladies boudoir. The two end cars were built to the same plan, at the extremity of each was a guard's compartment and next to it a luggage compartment with large sliding doors opening to the platform for the evacuation of lug- gage, next a compartment for servants travelling with their employers, and the rest of the car was fitted up for Pullman ticket holders. One of these cars was for smokers and the other was a parlour car. The train seated 112 passengers. A novel feature was the lighting throughout by electricity. The current was supplied from Faure's accumula- tors placed in one of the luggage compartments, and a dynamo for charging them was provided at Victoria station. On 1st December a special inaugural trip was made to Brighton via Dorking, Horsham and Shoreham but back by the direct appreciative account of the train added that "the experiment is one deserving of a sympathetic response by the travelling public for it exhibits for the first time in this country a mode of travelling in which every want of the passenger is anticipa- ted and by which the art of travelling will be shorn of every unnecessary inconvenience." The all- Pullman train was, however, but poorly patronized, so, in less than two months the Sunday train was oompletely withdrawn. The weekly service was continued, but before very long 1st class com- partment coaches from the railway company's stock were attached and the train ceased to be all-Pullman. The name Pullman Limited Express remained in the time table but in 1887 the words "Fast train" were substituted for "Express." When the all-Pullman train first ran the best timing was on the down joumey- Victoria to Brighton non-stop in 75 minutes, 40.6 m.p.h. done by the 15.50 weekday and 12.30 Sunday train, but this was no advance on previous express timings.
1888. Pullman Limited Fast Train.
A new Pullman train consisting of three cars, viz.-a parlour car, a buffet car and a smoking car with vestibulated oonnections—a recent invention and an advance on the open balcony connections of the 1881 train—was built by the Pullman Palace Car Company and completed at the London, Brighton and South Coast's carriage works at Brighton. Each car was 58 ft. long and the train was lighted by electricity, but the current was generated by the motion of the train. A trial trip was made on 10 December, and on the following day the train was put into general service. It took the place of cars used on the existing Victoria-Brighton Pullman Limited Fast Train to which reference has been made, and on Sundays it was substituled for the Pullman Drawing Room Car train which left Victoria at 10.45 and returned from Brighton at 20.40. No improvement was made in the timing. First class compartment coaches were always attached to the new train and sometimes additional Pullman cars. The author of British Railways in a later pamphlet on the London, Brighton and South Coast Railway published in 1896, states that by 1895 the Sunday train frequently consisted of no less than seven Pullman cars with six or seven 1st class compartment coaches. The time allowed from Victoria to Brighton on Sundays with stops at Clapham Junction and East Croydon, was 80 minutes; six specimen runs were given in detail by the author of the pamphlet and on only one occasion was time kept, in fact on that occasion Stroudley's Leatherhead No. 178, B or Gladstone class 0-4-2 with a load stated to have been equivalent to 20½ coaches reached Brighton one minute before time.
1898. The Brighton Limited.
On Sunday, 2 October 1898, a train consisting exclusively of Pullman cars was once again put on, and in contrast to 1881, was very well patronised. The new train left Victoria at 11.00. and returned from Brighton at 21.00. It ran only on Sundays and not at all during July, August and Sept. owing to the difficulty in securing a clear road in the. holiday months. During June the train left Brighton an hour later. It was first of all named, like its predecessor, The Pullman Limited Express, but early in 1899 the name was permanently changed to The Brighton Limited. From the outset this train was the first to be timed to run from Victoria to Brighton in an hour, and to do the same on the return journey. On its first run it was made up of five Pullman cars and two baggage cars; there was seating accommodation for 150 passengers, it was hauled by R. J. Billinton's 4-4-0 Smeaton No. 206, built in 1897. In spite of the fog which prevailed in the suburbs Brighton was reached in 41 seconds under the hour. On the following Sunday an extra Pullman car was attached, and, later on, the normal number of cars was seven. On 21 December, 1902, the train hauled by Holyrood No. 70, 4-4-0 built in 1901 made a record by reaching Brighton in 54 minutes from Victoria. The average speed was 56½ m.p.h., and between East Croydon and Brighton over 62 m.p.h. It is recorded by Charles Reus-Marten in the Railway Magazine, Vol. 13, p. 208, that on the 26 July, 1903, the same engine with a special train made up of three cars and two Pullman vans (about 130 tons behind the tender) ran from Victoria to Brighton in 48 min. 41 secs. at an average speed of 63.4 m.p.h. returning in 50 min. 21 sec. The Brighton Limited was superseded in 1908 by the Southern Belle which ran throughout the year on Sundays and weekdays and was in 1934 renamed The Brighton Belle, but this article is concerned only with the early Pullman trains.

One of the earliest railway guides.  W.E.S. Brown. 296
It is generally assumed that the first railway guide was issued by George Bradshaw (a member of the Society of Friends) on 19 October 1839, its title being Bradshaw's Railway' Time Tables, but J. Bridgen, of Wolverhampton, appears to have been first in the field with such a compilation. The latter's publication consisted of eight small pages of letterpress and two maps, enclosed in a cloth case bearing a yellow paper label with the words, Bridgen's Time Table of the Grand Junction, London and Birmingham, Birmingham and Derby, Bolton, Liverpool and Manchester, North Union, and the Manchester and Leeds Railways, London Hackney Coach Fares, etc. Two Maps, Price 6d." These maps were merely skeleton ones, much inferior to those published by George Bradshaw. The proprietor's name, "J. Bridgen, Wolverhampton," occurred three times on his guide. The first two pages showed the progress from Liverpool to Birmingham, the next two being occupied by a map of the route. Pages five to eight were devoted to the country between London and Birmingham, whilst pages nine and ten were occupied by the second map. The eleventh page contained the Manchester, etc. lines, and page twelve, the final one, a table of London hackney coach fares. The most historically important part of this little guide was the eleventh page, at the foot of which were the words, "Corrected October 18, 1839." This statement may reasonably be taken as implying that previous editions of Bridgen's Time Table" had already issued from his press, but in any case the date is one day earlier than that of the first impression of "Bradshaw's Railway Time Tables." The appearance of this eleventh page of the former publication may be judged by the reproduction of the same here given. It is highly probable that one or more copies. of this interesting pioneer railway guide may be still existent. The writer first became aware of it through an exhibition of early railway relics. held a number of years ago, when a copy was loaned thereto by an anonymous owner.

The Cannock Chase Colliery Comany's locomotives. 297-8. 3 illustrations
A previous effort made by the G.W. Railway to obtain Parliamentary powers to construct a mixed gauge line from Wednesbury to the Cannock Chase coalfield failed in 1854, as a result of opposition from the rival South Staffordshire Railway. The railways ultimately constructed by the C.C. & W. Railway comprised about 11 miles of single track consisting of four branches radiating from Chasetown to New Hayes, Anglesea Siding, Heath Hayes Colliery and Brownhills (Midland) respectively and the undertaking as then existing was therefore a purely local one serving the Cannock Chase Collieries. Physical connection was effected with the L.M.S. Railway (L.N.W. section) Littleworth Extension Line at New Hayes and with the Walsall-Lichfield line at Anglesea Siding, situate between Hammerwich and Brownhills (High Street) stations, whilst the Brownhills branch joins the Midland Section branch line from Aldridge immediately North of Brownhills (Watling Street) Station. A further connection with the Littleworth Colliery Tramway of the L.N.W. Section was also made at Conduit Colliery Junction by means of a short spur line off the Brownhills branch.
Passenger traffic had never been operated over any section of the Cannock Chase and Wolverhampton Railway, its activities being confined almost exclusively to the conveyance of coal from the Cannock Chase group of collieries. The line was, however, equipped with a system of semaphore signalling,
Three classes of locomotives were in use then, the oldest being saddle tank engines of the 0-4-2 wheel arrangement built by Beyer, Peacock Company and having the following dimensions :-
Coupled wheels .. 4 ft. dia. Trailing wheels 3 ft. dia. Cylinders (two inside) 14 in by 20 in 'Working pressure 125 lb. per sq. in. Heating surface (tubes and firebox) 645 sq. ft. Hourly evaporation 2,400 lb. approx. Water capacity 640 galls. Coal capacity 2½ tons Weight in working order 28 tons Total length overall 25 ft. 6 in. There were originally five of these locomotives, the names, dates and makers' numbers of which are shewn below:-
McClean 1856 (28)
Alfred Paget 1861 (204)
Chawner 1864 (462)
Brown 1867 (794)
Anglesea 1872 (1211)
Brown was withdrawn from service and scrapped in 1926, but the other four engines were still in use. No running numbers were allocated to these locomotives and the names carried by them are those of various personages who have served on the company's board of directors. They are of handsome design and closely resemble the engine Knighton constructed by the same builders for the Knighton Railway in 1861 (see Locomotive Mag. for February, 1936). Fig. 1 illustrates one of them as then running. The next locomotive to be dealt with is a six coupled saddle tank with inside cylinders built by Sharp, Stewart Company (Makers' No. 2643) in 1876. It is known as No. 6, and on account of its limited fuel accommodation this engine normally runs with an improvised tender, in the shape of a small coal wagon specially adapted for the purpose, attached. Its dimensions are as under:
Coupled wheels 4 ft. dia. Cylinders 16 in by 24½ in. Working pressure 145 lb. per sq. in Heating surface (tubes and firebox) 971 sq. ft. Hourly evaporation 3,500 lb. approx. Water capacity 900 galls. Coal capacity of tender 5 tons Weight in working order 30½ tons Length overall-· Locomotive 28 ft. 5 in Tender 13 ft. 10 in, Total 42 ft. 3 in.
Fig. 2 illustrates this locomotive, which, it will be noticed, is almost identical with the engine Pontypool which at one time ran on the West Somerset Mineral Railway and was an earlier production of the same builders (see Locomotive Mag. for July, 1914).
The last addition to the Cannock Chase stock was a six coupled saddle tank engine built by Kitson and Company in 1913 (Makers' No. 5036), and named Griffin after Robert Griffin, who was chairman of the company for several years until March 1913. There are no special features about this locomotive which had coupled wheels of 3 ft. 7 in. diameter, two 16 in. by 22 in. inside cylinders, a boiler pressure of 150 lb. per sq. in. and heating surface of 902 sq. ft. (tubes and firebox), an hourly evaporation of 3,500 lb., a water capacity of 900 gallons, a coal capacity of 2½ tons, and weighs 36 tons in working order. In common with the rest of the company's engines its chimney is ornamented with a copper rim, whilst the dome is of polished brass. It is illustrated in Fig. 3.
Although, with one exception, the whole of the Cannock Chase locomotives were over sixty years old, they were maintained in excellent condition and continued to perform useful work. They were painted dark blue and lined out in white, the names being carried on neat brass plates affixed to the sides of the tanks. In common with all other colliery undertakngs a large number of coal wagons were owned, but the only other rolling stock in use are some brake vans made out of covered goods wagons, and a few flat wagons fitted with brakesman's sentry boxes, The locomotive running shed and repair shops were located at Chasetown.
In conclusion, the writer is indebted to the Directors of the Cannock Chase and Wolverhampton Railway for permission to publish this article and to M.J. Foggo, the general manager, for verifying and amplifying certain information contained therein.

PULLMAN CAR SERVICEs.. 299
Owing to the War, several of these services have been withdrawn, but there are a number still running on the Southern Railway. There the cars have been thoroughly "blacked out" and have provided the only method of travel during the hours of darkness in which it has been possible to dine and read one's paper in comfort under present conditions. ------

*A UNIQUE PIECE OF RESEARCH. 299
It is known for a fact that in September, 1829, a locomo- tive was sent off by Robt. Stephenson @ Co. for the Balti- more and Ohio Railroad. Warren in his "Century of Loco- motive Building, calls it "Whistler's engine", but gives practically no details. In an old book which came to light afterwards, there is an entry showing that it was shipped on the sloop Eraser on Sept. 17, at Newcastle-upon-Tyne, er> route for Liverpool. After that, it seemed to vanish in thin air. There is no mention of it in Hungerford's "History of the Baltimore and Ohio Railroad. Mr. C. F. Dendy Marshall discovered that the Eraser was wrecked at Peterhead on Sept. 28. An account of the wreck from the "Aberdeen Journal" of Sept. 30, 1829, will be found in his forthcoming work "Early British Locomotives." From a careful study of the account, together with a nearly contemporary map of Peterhead harbour in the "Life of Thomas Telford," 1839, and a survey on the spot, it was possible to be almost certain, within a very small area, of the spot where the Eraser must have struck.
In August, 1938, Messrs. Dendy Marshall, R. E. Pennoyer, W. J. Tennant and Captain E. W. Swan (members of the Newcomen Society), employed a diver to make a search, which lasted three days, under the superintendence of the last-named. The bottom is clean rock, without any sand, but in spite of this, nothing could be found. Perhaps it was too much to expect that anything had survived, after more than a century of gales on one of the most exposed parts of the coast of the British Is

A necessary corollary was that the whole of the valve gear had to be placed outside, which although rendered far more accessible, was a feature of doubtful value on an engine of this class as it became much more liable to damage. Leading dimensions were, cylinders 9 in. by 15 in., diameter of wheels 27 in., wheelbase 4 ft. 6 in. The boiler had a diameter of 2 ft. 6 in. and an overall length of 6 ft. 3 in. ; it contained 64 brass tubes of 2 in. outside diameter. The fire- box, of iron, had a heating surface of 20.5 sq. ft. which, in conjunction with the 213 sq. ft. of the tubes, gave a total of 233.5 sq. ft. The tank held 300 gallons of water, and in working order the engine weighed 11 tons. The gauge was 4 ft. 8! in.

The Dickson all-metal laminated gasket
Consists of a number of metallic laminations, different combinations of metal being used according to the type and service of the engine concerned. For example, all copper is used for marine and aircraft engines, while for Diesel engines they are either all copper or a combination of copper and terne plate, which is cold rolled steel, annealed and coated with an alloy of 80 per cent. lead and 20 per cent. tin. For small petrol engines combinations of copper-aluminium, copper-terne plate and alurninium-terne plate are employed, while terne plate is used for heavier engines. The thickness of the gaskets is usually 0.04 in. to 0.06 in. for exhaust and intake joints and 0.05 to 0.06 in. for cylinder head joints, while laminations are 0.010 in. thick.

First European 4-6-0 locomotive. C. Hamilton Ellis. 300. diagram (side elevation)
Re article on the Swiss National Exhibition a 4-6-0 locomotive for the Gotthard Railway, built in 1883 was mentioned. I was under the impression that the first European 4-6-0 locomotive, at any rate on the standard gauge, was the one built at Turin to the designs of Cesare Frescot, for the Upper Italian Railways, in 1884, a drawing of which I enclose. It was the prototype of the famous Vittorio Emanuele class on the Mediterranean system, later engines having alterations in detail, such as domes on the after ring of the boiler instead of behind the chimney. I am advised by the Swiss Federal Railways that the first Gotthard 4-6-0 locomotives, Nos. 201-2, class A 3/5 were built by the Swiss Locomotive and Machine Works, Winterthur, as late as 1894. The Italian engine had 5 ft. 6 in. coupled wheels and two cylinders 18½ in. by 24 7/16 in. with outside Gooch link motion. The working pressure was 156 lb. per sq. in.

Many changes in steam engine design and practice have taken place during recent years. The reciprocating type is still used as a prime mover and will be for some time to come, but it has to a large extent been superseded by the turbine. The internal combustion engine has also reached an important position as a competitor for both land and marine practice.

The importance of braking. 301.
Having started a train the most important thing is to be able to stop it, no easy matter—at least within the requisite distance—with the high-speed trains which operated up to the beginning of September. With automatic brakes, the increase in weight of the standard express train during recent years has not increased the braking problems, but long-distance schedules of 70 m.p.h. and short-distance start-to-stop timings in excess of about a mile-a-minute have caused serious difficulties in design and in maintenance, whether the braked weight is light or heavy. The magnitudes of the forces involved in a full-application or emergency stop of a high-speed train do not appear to be generally realised, although they are amazing. For example, with an axleload of 18 tons, a stop from 100 m.p.h. in 1,225 ft., if praoticable, would involve the dissipation of forces up to an instantaneous maximum of 2,000 h.p. per axle, or 500 h.p. per block, that is, 2,000 or 500 multiplied by 550 ft.-lb of work per second. Instantaneous forces of this magnitude can be attained.
For such instantaneous rates of retardation the mechanical problems associated with the brake gear and the wheel-axle assemblies are anything but simple, for the mechanics of a stop from high speed are full of complex variables, each of extremely short duration, an outstanding example of which is the variation in friction. If it is assumed that the ratio of the braking force to the wheel load must not exceed 25 per cent., that is, equal to the value of the coefficient of adhesion between a wheel and dry unsanded rail, the maximum rate of retardation will be about 5.5 m.p.h. p.s., but as a large allowance must be made for difference in rail and adhesion conditions, say 18 to. 20 per cent. of the mean, the braking rate wi th rails under the worst conditions would be only 3.3 m.p.h.p.s. as a top limit. From a speed of 100 m.p.h. a stop at an average rate of deceleration of 5.5 m.p.h.p.s. would be made in approximately 1,350 ft., but a rate of 3.3 m.p.h.p.s would require 2,225 ft., an increase of 65 per cent. and more akin to the quickest actual emergency stop. During such stops the rate of deceleration would vary greatly, and some form of deceleration controller would be essential. In order to obtain high-speed stops with consistent regularity without fear of wheel sliding it is becoming common to apply sand to the wheel treads whenever a full application is made.
Important though the mechanical problems may be, they certainly do not outweigh those associated with the adequate dissipation of the heat generated,. a side of the braking art which is linked indissolubly with maintenance and repair, and also with frictional variations. Flames, let alone sparks, have been known to stream out from tread blocks in the course of emergency stops from three-figure speeds. It is this question of heat which has led to the general elimination of the drum brake on European high-speed railcars, and the substitution of disc brakes or special forms of tread blocks. Yet, strangely enough, America is just discovering the non-tread brake, and one high-speed train—the General Pershing Zephyr—has been fitted with a disc form experimentally. Drum brakes, and disc brakes, too, seek to take advantage of the constant coefficient of friction of such materials as Ferodo, but the opportunities of gettmg rid of the heat are so limited that on the Danish State Railways 16 per cent. of the entire mamtenance costs of the first four Lyntog diesel-electric trains were due to brake drum lining renewals. On the Belgian National Railways an increase of three to five minutes of certain timings reduced the drum brake lining costs by nearly 50 per cent. In France attempts have been made to use the advantages of cast iron and special friction materials by using articulated blocks comprising both substances.
The high retardation rates possible with electro-magnetic track brakes cannot be used fully, because of purely railway considerations, such as points, crossmgs, track circuits, sanding and the like. As braking forces, apart from such novelties as wind brakes, are dependent upon the wheel and rail conditions, It is the pneumatic-tyred vehicles which can be stopped most quickly, as many bruised travellers will testify, and actually deceleration rates up. to 13 m.p.h.p.s. have been recorded With Michelin cars, that is, well over half the rate of g, or 32 ft: per sec. per sec., which results when the retardmg force is equal to the weight bemg braked.

Lightweight passenger stock. 302-3.
For presentation at the American Summer Meeting of the Institution. of Mechanical Engineers which was to have been held m New York, W. A. Stanier, vice-president, prepared a paper on lightweight passenger rolling stock, describing developments which have taken place in the last seven years on the London, MIdland and Scottish Railway.
As the author pointed out .in his introduction, due to limitations of axle-weight m this country the tractive effort of a six-coupled engme is in turn limited to about 40,000 lb. w.hich fixes the maximum weight of a passenger train at 600 tons. We may remind our readers that, even if considerations of keeping the train weight within the power of the locomotive do not anse, weight reduction is still a desirable aim, for the lower the train weight the greater will be the acceleration and retardation and the lower the fuel and track maintenance costs.
Weight reduction may normally .be effected by the use of light alloys—usually a high-priced procedure—or as in the case of the stock described in the paper, 'by scientific design. It was stated that the normal British passenger coach consists of a steel underframe surmounted by a timber body, in some cases with outside panels of . sheet steel; this type of construction which results m. the weight per passenger seat m a third-class corndor coach being about 1,600 lb. has, WIth minor refinements remained comparatively standard for some time but since 1932 serious attempts have been made to reduce weight by new methods, and de- parture from. the traditional British standard form of construction is gradually taking place. The introduction of electric welding and the availability of suitable high-tensile steels have been the corner stones of recent progress and have permitted a freedom in design formerly unattainable. Timber has been gradually eliminated, resulting in an increasing identiftcation of the under frame and body, the all-steel coach having a weight of about 500 lb. per passenger seat.
This result was greatly contributed to by combining the body side and underframe into the form of a Vierendeel truss; this truss in a simplified form consists of a rigid frame incorporating parallel top and bottom booms with equal sections, and a number of vertical columns which are rigidly connected to the booms, to transmit bend- ing moments as well as tension, compression and shear. Regarding the body in this manner, the main under frame members form the bottom boom of the truss, the roof structure forms the top boom while the body side pillars perform the functions of the columns.
The author proceeded to analyse this arrangement and explained in considerable detail the method of calculating the stresses in the different members, diagrams being included to show the shearing force and bending moments of coach components constructed on this principle. Turning to the oonstructional side it was pointed out that although the conditions of limited production prevail, unit assembly had been achieved on new lines, but based to some extent on the construction of the old type of wooden car. As already mentioned, the possibilities of fabrication by electric and spot welding have been extensively employed; considerable press work is involved and jigs are largely used—the latter are a necessity as apart from the time saving effected they ensure the attainment of the degree of accuracy necessary.
While the stock described in the paper was built for use on the electrified Liverpool and Southport section of the L.M.S., as the author pointed out the principles involved appear equally applicable to main line stock, although after each new step forward a period of consolidation is desirable in which to study behaviour of the vehicles. Particulars of overload tests were described, these being made on the finished structure and although of an exacting nature, involving 100 per cent. overload, no greater variation than 1/16 inch occurred in the door pocket openings, the maximum deflection of the solebars under the condition mentioned being 5/16 inch.
Referring to the direction in which future progress may be sought it was suggested that as public demand for comfort in travel is always on the increase, it is possible that the bottom of the curve of total weight per passenger has been reached, but for operating economy it is desirable, if possible, to avoid any upward trend in tare weights. This puts the designers and constructors on their mettle in devising further savings in weight on the purely structural portion of the vehicles and in this sense progress is unlikely to be arrested. The body and under frame are already merging one into the other, suggesting a modified form of tube as a further line of development.

Lighting of trains test on L.M.S. 318
The first test of methods for the lighting of passenger compartments on long-distance trains during the "black-out" hours, was carried out on the L.M.S. Railway's 16.50 Euston to Heysham express on Monday, 30 October, This experiment follows research on the part of the railway companies, the Ministry of Transport, and the Home Office. The system tried out on the Heysham express can only be applied on main line trains; the greater number of stops made by suburban trains, together with the universal use of compartment doors on suburban stock, renders it impracticable for application to such services. Separate experiments are, however, being carried out by the railway companies in conjunction with Government departments with a view to seeing whether it is possible to provide a better standard of lighting in suburban trains. The standard of lighting tried out affords sufficient interior illumination for reading even small type. The opalescent light shades previously used are replaced by black shades which throw the light down directly over the passenger seats, whilst the windows are painted all round on the outside with a four-inch black border. In addition, close-fitting blinds are installed, which are kept drawn during the hours of darkness. Owing to the difficulty of obtaining the necessary materials it will not be possible to introduce the improved lighting on all main line trains for several months at least, but at least eight of the principal expresses will be equipped and running by now. The newly-equipped trains will be operated at first on the most important services running, during the hours of darkness, between principal centres of population. It is intended that these improved lighting facilities will be available on all main line trains. It is pointed out that the success of the present experi- ment depends to a large extent upon the co-operation of the travelling public for whose benefit it has been introduced,

The Hatfield-St. Albans branch which was closed for passenger traffic at the outbreak of war has now been re-opened. The suburban train service between King's Cross and Moorgate has been suspended since the commencement of hostilities, all local trains being now run to and from King's Cross terminus or terminated at and started from Finsburv Park. The L.M.S. through service between Broad Street and G.N. suburban stations has also ceased to operate. The Finchley (Church End) and Edgware branch has been closed but in this case a special service of buses is running in lieu of the passenger trains. The passenger service over the new line between Hertford North and Hitchin is also discontinued for the present.

Some early Pullman Cars. J. Pelham Maitland
Canon Fellows' article in the October Issue affords a valuable synthesis of information on this. subject. It only contains, however, the briefest references to the two baggage cars constructed by the L.B. & S.C.R. in 1888 to match up with the Pullmans. These were 6-wheeled vehicles with Pullman type clerestory roofs and other similar details externally. No. 29 was also remodelled to conform to the outline of the cars when the end platforms were finally abolished, and early in the present century was repainted in the cream-and-umber livery then adoptel as standard by the Pullman Co. It lasted in service, I believe, until 1913, when it caught fire owing to a short-circuit from the dynamo, and was subsequently broken up. On the other hand, No. 80 remained in its original condition until the absorption of the L.B. & S.C.R.. by the S.R. became effective. It had not been in service' for many years previously, and did duty as a Carriage-Examiners' Lobby at Lover's Walk Carriage Shops, Brighton, until the end. I can never recollect ever having seen this van on the road, although I can well remember the cars with the open platforms referred to by Canon Fellows, and also the very elaborate panelling and gold lining which, survived until about 1902.
As long as the L.B. & S.C.R. lasted, the 10.05 down train and the 13.20 up, on weekdays, were colloquially- referred to by the operating staff as "The Pullmans." Vans 29 and 80 were designated the "Pullman Pups", by the same people.
It should also be recorded that the Sunday Pullman Ltd. train was designated in certain Victorian circles as "The Sabbath Breaker" for some years after its inception. See also letter from Stephenson V. Knight on page 357

Bridgen's Time Tables. Reginald B. Fellows. 327-8
Mr. Brown is quite right in thinking that the words at the foot of page 11 of Bridgen's Time Tables "Corrected October 18, 1839" indicate that there was an earlier edition. The Time Table was advertised in The Railway- Times of 5 October 1839 as follows:-"Alteration in the arrival and departure of Railway Trains Oct. 1 1839. This day is published price 6d. done up in cloth in so concise a way as to be adapted for the waistcoat pocket Bridgen's Time Table of the London and Birmingham, Grand Junction . . . Railways . . ."
So it was some weeks ahead of Bradshaw's publication of 19 October. But James Drake of Birmingham was much earlier, his maps and tables were first published in July 1838. The time tables showed the trains between London and Denbigh Hall and between Rugby and Birmingham with the connecting coach service, also the trains on the Grand Junction, and the Liverpool and Manchester Railways. New editions were issued in October and November 1838 and the latter included five railways. The maps were very elaborate, but the publication "in a case for the pocket" cost 2/-.
E. H. Dring read a paper on "Early Time Tables" to the Bibliographical Society in 1921, and the following is extracted from it:—

"Among other contemporary time tables are:

A note on p. 2 states that this is a new and improved edition. In 1904 there was exhibited at the Old Manchester Exhibition at Manchester an edition of this Time Table on page 11 of which there was printed 'Corrected October 18 1839'. a day earlier than the date of the earliest Bradshaw."

The continued need for efficiency. 329
W ITH some engineers, during the embryonic period of training and in the earliest stages of their subsequent careers, the definition of efficiency is strictly confined to the thermal and mechanical implications of the term. Individuals in this category, and also others who are uninformed and equally misguided, are prone to decry the low thermal efficiency of the steam locomotive, unmindful of the fact that its ultimate efficiency, that is, in the: economic sense, is high and has enabled it successfully to compete in many fields, as it will undoubtedly continue to do for many years, with rival forms of motive power which are more efficient in the purely technical applications of the word. As his experience widens, however, the young engineer realises that efficiency goes far beyond mere technical considerations. In its widest sense it may be defined, possibly a trifle loosely, as the performance of given work in a satisfac- tory manner with the lowest ultimate outlay of money. Railways have been all too familiar with this interpretation, and the necessity for its trans- lation into practice with accompanying, true economies in every direction, over a long period of financial stringency. A timely reminder was recently issued by an executive of the L.M.S.R. to the effect that control of the home railways by the Government is neither excuse nor reason for any relaxation of effort in the search for increased efficiency, wherever it may be attained. There can be no disagreement with this statement, which must indeed be accepted as an axiom and applied universally. The achievement of greater efficiency, always essential to ensure :financial stability, is imperative when war is being waged under modern conditions with victory as the goal; economic and military considerations are then of equal import- ance, and waste on the home front is as much a potential cause of defeat as, for instance, shortage of troops or ammunition in a vital sector of the front line.
With statistics and other data available, the managerial and technical staffs of the railways are well able to observe changing trends and, after' analysis, to meet them by instituting new methods of administration and operation, improving exist- ing arrangements, modifying lay-outs and shop processes, and by effecting improvements in design. Although it does not necessarily happen, it is at the same time possible that with a broad outlook available, some details which are capable of improvement may be overlooked. Given the intelligent application of his powers of observation and deduction, the man who uses these details in the course of his daily work is well qualified to' suggest improvements for them. On some rail- ways he is encouraged to do so by monetary awards for all suggestions which are put forward and, after investigation, given effect. There are two very important points to be con- sidered in the working Q1f all suggestions schemes. In the first place the staff should be encouraged to make suggestions, with identical opportunities for reward, in connection with the work of both their own and other departments; enginemen, for instance, are frequently able to suggest improved methods of operation, train control and signalling, and operating staff, alterations in the design of carriages and wagons from the functional aspect. Secondly, the reward should bear some propor- tionate relation to the savings effected by the suggestion adopted; there is no encouragement for further suggestions to be made when a man, know- ing full well that his suggestion has saved his employers literally thousands of pounds, is rewarded with a sum of, say, five pounds which, by comparison, is beggarly. If in such cases the' maximum amount of the award is arbitrarily limited, then suitable promotion in addition might be considered.
Suggestions which are well beside the mark as regards practicability should not be coldly dis- couraged, or even merely formally acknowledged; this is a psychological error. I t is quite possible that the originator, unless basically irresponsible, will go on and in time produce a really valuable suggestion. Further, the examination of an ap- parently worthless suggestion frequently opens up an incidental matter and leads to an improvement in a direction far removed from that originally intended; even so, progress has been made. The search for, and attainment of efficiency and true economy must continue ceaselessly, irrespective of the method adopted.

Some aspects of railway progress as they affect the locomotive department, 330-3.. 2 illustrations
Continued from page 305). (All references to operating features referred to in these articles are necessarily on a pre-war basis). Through Engine-Workings. The suitability of the modern locomotive for longer continuous service has had a considerable effect upon operating practice. Obviously this capacity for greater continuity of work presents an opportunity to the operating authorities, of which they have not been slow to take advantage. Engine-workings have been revised so that the number of changes en route are reduced, continuous runs of as much as 400 miles by one engine being now a commonplace. Again, an engine is booked to work a train for about 100 miles to its destination; whereas previously the train-destination was also that of the locomotive, the latter now picks up another working in the same direction, and at the end of that, yet another, working perhaps four or five such stages before setting out (even by an indirect route) on the return journey to its home depot. This return journey, again, may be made by successive stages. This system has necessarily involved the abolition to a large extent of the practice whereby particular sets of enginemen were kept to a particular locomotive; as many as eight or a dozen different sets of men may now handle a main line engine between its leaving its home shed and its return there. Moreover, some of these men may be only "terminal relief" crews who take over from the arriving crew because the latter's time is up, and who take the engine to shed (not necessarily its home shed) for coal, water and other attention pending its being taken out again by a fresh crew. Here again, standardisation of locomotive types has proved extremely valuable, because it is essential to the success of any system of intensive work- ing, that the engines used shall be of types with which all the different crews are likely to be familiar. This practice could not have been suc- cessful in the early days of British railway amal- gamation, because of the widely divergent designs of locomotives then in use and the difficulty of in- structing "foreign" crews in their efficient working without spending a great deal of time in training.
The greater continuity of locomotive user is, of course, a considerable asset to the Operating authorities, since it enables a substantial aggregate saving of time previously allowed at intermediate stations for the changing of engines—although it has to be recorded that full advantage is not always taken of this factor.
This policy also has the effect of reducing the importance of some of the intermediate running- sheds, as does the allied practice of working many branch line trains, previously powered from a local depot, by engines of main line type which spend their terminal margins in this manner. Modern Signalling Developments.
In the decade that immediately preceded the Great War it appeared as though a degree of finality had been attained in British signalling, at any rate in the indications displayed by night and by day. The introduction of the day colour- light signal, in 1920, proved however to be the beginning of a series of developments that have had a marked effect in train operation. A number of these improvements belong solely to the realm of signal engineering technicalities; a proportion have been designed to facilitate traffic operation, by the concentration of control at important junctions and termini in one or two large signal boxes instead of a large number of small ones. But any effect upon the locomotive department of schemes in the above categories is at the most an indirect one, and in- teresting though they may be from the scientific point of view there are other developments of far greater, in fact vital importance to the men on the footplate; it is these that are dealt with in the present article. British practice only is covered; signalling on the Continent and farther afield is in many cases based upon different principles altogether, and to consider them would be impos- sible in the space available. During the last twenty years there has been a general seeking after more logic in signal indications, a trend towards making things simpler for enginemen, and among numerous developments of this kind none was more needed than the alteration in colour of 'the distant signal warning indi- cation, from red to orange. Until the advent of the three-position signal there was strikingly little to distinguish a distant from an absolute stop signal; the fishtail arm is recognisable from a fair distance by day, but very few railways made any attempt to differentiate between the two at night. Both displayed a red light in the "on" position, and a driver had to depend on his knowledge of the road to determine whether it was an absolute stop, or only a warning signal that he was approaching. In some cases an illuminated "fish-tail" was displayed to the right of the red light, and the former Furness Railway used a flashing red light for the warning indication. Such practices were, h ever, isolated rather than general. Signal Anomalie A bolishe . When signals displaying three separate indications ,"all-clear," "caution," and "stop" were introduced into this country,. orange was chosen as the colour for night indication of the "caution" aspect. The practice was extended when the first three-aspect day colour-light signals were installed.
From that it was a logical step-though one that involved an immense amount of work-to change the night indication for the "caution" position in all distant signals from red to orange; at the same time the painting of the semaphore arms was changed from red to yellow. Although tolerated for so many years, the prac- tice of allowing a driver to ass signal relating to his particular road th was dis laying a red light, was neither helpfu nor.Iog ical. ce it was abolished, attention was turned to other anomalies of a similar kind. In the middle nineteen- twenties many existed; a number still do, but one particular problem became aggravated when colour-light signalling was first installed at big termini and junctions. To cut to a minimum hand and verbal signalling of shunt movement it be- .came, for a while, the practice to use a large It may be argued that the experienced driver would have no difficulty in distinguishing these subsidiary lights from his own; that, however, is only the distant signal argument in another form, and since then welcome steps have been taken to remove the objection. The trouble occurs princi- pally when colour-lights are used for the main run- ning signals, and in such cases two different solu- tions have been found. On the Southern Rail- way, and on the electric railways of the London Passenger Transport Board, disc signals are being standardised; to avoid the use of coloured lights of any kind at night, and at the same time to dis- play the same kind of indication, these discs are floodlit after dark. Floodlighting is, however, only possible at stations where a supply of electric- ity is available, and at country stations and other places outside the colour-light areas a compromise . When placing distant signals further out, to give longer braking distances for high speed trains the new distants are usually colour lights, arranged for long sighting. number of miniature light signals, the majority fixed at ground level. Though not so penetrat- ing as the main signals the light thrown from these ground indications was far more powerful than anything used hitherto for the same purpose, and the driver of a train making a running, as opposed to a shunt movement, had to pick his way, as it were, among a veritable carpet of red lights. The difficulty was made worse by the diffused nature of the light-beam; in the case of a main running signal this is fairly concentrated in order to obtain the maximum length of range, but a shunt signal has often to be observed from a wide angle and the optical system was designed accord- ingly. In consequence, when approaching a big centre the whole array of ground signals facing the direction of approach were seen from the foot- plate. has had to be made for night working. Oil lamps provide the necessary lighting, but the spectacle glasses in the discs-particularly the reds-are made so small that the chances of confusion with a running signal are very  slight.
In the North-Eastern Area of the L.N.E.R., what is termed the "position-light" signal has been adopted for shunting purposes in all recent power installations. In the case of the ground signals two white lights are displayed horizontally for "stop," and the signal to proceed on a shunt movement is given by two white lights dis- played diagonally. The same indication is given by day and by night. For the daytime, fairly strong lighting is needed to give a distinct indication; the background of the permanent way is not ideally suited to the display of white lights, and it is not usually possible on account of structure gauge limits to. provide a sighting board. At night the conditions are reversed, and in all recent installations apparatus has been provided far re- ducing the voltage on the lamps at night sa that the white lights are not so bright as to. interfere with the sighting, at lang range, of the main running signals.
Reducing Number of Signals.
The desirability of avoiding as far as possible the need for a driver to. pass a red light of any kind, whether it relates to. his particular route or not, applies with even greater force at junctions, both at high speed layouts and in the approaches to. stations with many platforms. In the heyday of semaphore signalling, the approach to. a busy traffic centre was marked by a forest o f signal arms, changing after dark to. a galaxy of lights. cators have been tried, but the one that seems likely to. have the widest application is the so-called theatre-sign indicator. This, as its name suggests, has a large number of small lamps arranged an a square black display ground; various combinations of lamps are selected electrically in order to. produce the platform numbers or route symbols required, and a very clear indication results. A smoky front glass does not appreciably reduce the visibility, indeed in same instances tinted glass is used to. soften dawn the brilliance of the letters. This type of indicator is, however, only suitable for slow running locations, such as the entrance to. a big yard; the indication dis- played could not be recognised far enough away to be of any use to. a driver approaching a junction at 80 m.p.h.
Even before the ooming of colour-light signalling some of these picturesque, though somewhat over-whelming displays had disappeared, and a com- paratively few arms, with route indicators, functioned in their place. But though excellent in theory the route indicator was not an easy appli- ance to produce in a form complying with all the strictures of practical railway operating, A roller- blind, or a series of enamelled plates, was more or less satisfactory for daytime, but at night, unless the characters were exceptionally large, illumination was difficult whether performed by a light shining through a stencil, or by a half-hearted attempt at floodlighting from the front. The plates, too, quickly became grimed with smoke. With the introduction of colour-light signalling, quite a variety of internally illuminated route indi-
High Speed Junctions. The signa' of high seed junctions has been the subject of m eh contro ersy, and it has always been found diffic t obtain a full measure of agreement as to how much or haw little inforrna- tion should be given to. the driver af an approach- mg tram. One school of thought advocated what has been termed "speed signalling" -a system that tells a driver only the speed at which he may run, and gives no indication, geographically or otherwise, of the direction in which he is being routed. Other practices give varying degrees of information. From the engineman's point of view the fullest information as to the state of the road ahead is desirable, for then he can run with confidence and get the best aut of his engine when///incidental delays or unusual routing takes place. Nowadays this is generally recognised, and the latest developments in both semaphore and colour- light signalling are proving very successful in the operation of heavy and fast traffic.
The problems concerned in the signalling of a junction where high speeds obtain are best understood by taking a specific example, an ordinary double-line junction of two main routes "Line A" and "Line B," both us - express trains; there is a passenger statio earby, nd through this sta- tion there are loops n both the and down sides. A train approaching the junctio in the facing direction can pass through on anyone of the four routes: via fast road to Line A: via loop road to Line A; via fast road to Line B ; via loop road to Line B. As a specific instance the case of a high- speed express passenger train may be considered. Normally it passes at about 80 m.p.h. via the fast road, to Line A, and on 99 out of 100 occasions no kind of delay is experienced at this station. Then comes a day when, owing to some special train working, the down fast platform road is occupied and the train standing there cannot be cleared in time to give the "flyer" its normal road. One is naturally anxious to cause as little delay as pos- sible and the kind of message to be conveyed to the driver is: "We're putting you through the loop to-day. All the signals are off, but don't forget there is a 35 m.p.h. speed restriction over the points at both entering and leaving ends." Conveying Information to the Driver.
How is such a message best to be conveyed? To be really effective it must be given to the driver at the distant signal, for then he has time to pre- pare accordingly. Considering first the signalling of such a layout with semaphore arms, it is the practice in some localities to provide only one dis- tant arm, and to lower this only when there is a dear straight run through on the main line. In the particular case under consideration the distant arm would be at "caurt:ion," and the driver, not knowing what to expect, would slow right down preparing to stop. The signalman in his turn would probably keep the home signal arm relating to the loop at danger until the train was fairly close, to ensure a slow passage over the turnout, and the driver, seeing this signal clear in front of him, would crawl on expecting to be stopped at the starter-a-the latter at present obscured by the sta- tion buildings. At last he would "get the road" but even so might proceed to the next block post less energetically than the circumstances require, simply because he half expects to be delayed again.
An alternative method of signalling, and one that is finding favour, is to provide" splitting" distant signals. In such a case as that under consideration, there would probably be at least two, and most likely more distant arms. It would thus be possible to advise a driver, not merely that he was being diverted from the straight run, but also that the loop line was clear throughout. The geographical disposition of the actual arms in relation to one another provides a clear indication of the route to be followed, and at the same time gives an adequate reminder of the necessity for reduced speed over the turnouts. At night the position of the green light .in relation to the other three, which are showing orange, acts as a route indicator and a speed indicator as well. This system may be criticised on the grounds that it increases rather than decreases the number of signal lights dis- played; but with semaphore arms and oil lamps, this is not a serious disadvantage, and in the majority of layouts it is more than outweighed by the improved operation that it permits.
Illuminated Direction Indicators.

With day colour-light signals it is of the great- est importance to reduce the number of lights displayed simultaneously. Here a beam of infinitely greater intensity is being dealt with; the lenses are much larger, and the range at night is something over two miles. In designing, a parallel shaft of light is aimed at, but in actual practice there is a certain amount of "spread." At close range this is negligible, and the beams from two adjacent Lights are well separated. But seen from a mile off it is a different picture; the spread is sufficient to cause a certain ,intermingling of the beams, and in the case of a splitting signal, one unit of which is showing green and the other red, it might well be difficult to decide which route was signalled, since the optical mixing of red and green produces a white light. It is to avoid the use of splitting signals in colour-light territory that illuminated directional signs have been introduced. Indicators of this type have been installed on the L.N.E.R., the L.M.S.R., the Southern, and the surface lines of the L.P.T.B., and it seems probable that the type will come to be recognised as the standard junction route indicator in this country for use in colour-light areas.
Indication is given by a row of white lights pointing away from the lens of the colour-light signal. At a junction, the route of least diverg- ence from the main line is indicated by a row of lights inclined at 45 degrees to the vertical; the next route to the left, or right, is indicated by a horizontal row, pointing to the left or right of the main signal as the case may be; a third, and still sharper divergence, is indicated by a row of lights pointing downwards at 45 degrees to the vertical, though the locations needing this sign have so far proved somewhat rare. For a main line move- ment, 110 indication whatever is given, the driver of an express seeing displayed only the green light of the main signal. For a diverging movement, very complete information can be given as to the state of the road ahead, and by the display on the main signal of an indication, such as a "double yellow," more res tricti ve than the "green," there is conveyed a valuable reminder of speed limits over turnouts.

High-speed lightweight trains. 334-6
Continued in next volume page 18.

C.T. Ripley, Chairman of the American Society of Mechanical Engineers, Railroad Division, presented before that Society a comprehensive paper with the above title. The subject was one claiming considerable interest on both sides of the Atlantic, and, we consider, merits a comparatively detailed report. The author commenced by drawing attention to the expansion of travel habits during the last twenty years, which growth was attributable to the development of cheap cars and the construction of suitable roads. Proceeding to trace the evolution of coach construction it was stated that in 1900 the 60 ft. wooden passenger car, seating about 80 passengers, weighed about 40 tons or 1,000 lb. per passenger. In the interests of safety, designs were changed first to include steel underframes, and in about 1910 to all-steel construction. Various parts were also increased in size and weight in order to secure greater strength and durability, until in the 1920's the 80 ft. passenger car seating about 70 passengers weighed approximately 80 tons or 2,300 lb. per passenger. About 1930 still further weight was added, due to the introduction of air-conditioning equipment, weighing about 5 tons. As a result of this continued increase in weight of passenger cars, as well as a gradual increase in the speed of operation, the size of steam motive-power units steadily increased. Track structures and bridges had to be made stronger to carry these heavier locomotives and cars, and thus there was, from all of these angles, an increase in the cost of operating passenger trains, while at the same time the total traffic was diminishing and there was a continual demand for lower rates to save the remaining traffic.
About the same time some new structural materials became available for use by the car builders, namely, aluminium alloys, stainless steel, and various so-called low-alloy high-tensile steels. Because of these developments the railway engineers and the car manufaoturers started active work in the design and construction of new trains of a lighter type for main-line operation. The first of these were small trains consisting of three or four cars with 600 h.p. Diesel engines located in the head car. They were made as light as possible to hold down the power requirements and to enable them to. compete with buses and private automobiles by giving cheap transportation. The cars were of non-standard height and same were narrower than the standard. They were streamlined to reduce power requirements and also. to make an appeal to. the public, already educated to. such design by automobile developments
The reaction of the travelling public was so favourable that there was an immediate demand far mare elaborate and larger trains for longer runs, with sleeping accommodations and other features for maximum comfort. Low first cost was soon last sight of in this development. Interior decorators designed the mast elaborate fittings and the trains were built with as many as 14 cars with power units. totalling as much as 5,400 h.p. and auxiliary power far the cars of 1,200 h.p. A few of these trains were powered with streamlined steam locomotives but there was little change in the design of these locomotives from the old type except that large: drivinlg wheels (84 in.) were used together wIth higher steam pressures (300 lb. per square inch) and larger tenders to. reduce delay in taking fuel and water. They also had roller bearmgs and some other refinements in desi
gn, Mast of the early trains had articulated cars because at was thought that this design reduced weight and gave better riding conditions. It de- veloped however that neither of these factors proved to be important. There was a definite disadvantage in articulation particularly an ~ong runs, in that standard cars could not be mixed with such cars In case of difficulty, such as a bearing or wheel failure, a car failure might be- came a train failure. In the last few years practi- cally all the lightweight cars have been built as individual units with standard floor and coupler heights and standard outside dimensions, so that they can be associated with any standard car. The weights of these cars were reduced about 40 per cent. from those of the conventional structural- steel cars and thus four-wheel trucks could be used. The only standards far design strength avail- able at the time mast of these cars were built were the provisions of the United States Railway Post Office mail-car specifications. These specifications were first prepared in 1912 by a group of repre- sentatives of the Post Office Department, the Master Car Builders Association, and the car manufacturers. It was required that all postal cars meet these specifications. While other cars were not required to. meet them, practically all pas- senger-train cars were designed at least to. these requirements.
In 1938 new specifications, based an the United States Railway Post Office mail-car specifications, were produced to cover practically all types of con- struction with all types of materials. The major provisions of bath the earlier and 1938 specifications were, first, a minimum strength of centre- sill construction based an 400,000 lb. buffing static load and a factor of safety of two, and second, a minimum strength of end construction to protect against telescoping action. This latter required minimum section moduli for vertical end members and minimum shear values far their top and bottom connections. There were also. numer- ous other limitations of stress in frame members. Cars built to. meet these specifications have rendered excellent service with a remarkably good record in the protection of passengers under wreck conditions. As a consequence when lightw construction was started in about 1931 these speci- fications were used as a minimum requirement, even though there were no rules of the American Railway Association or of the Government setting such limitation. However, a feeling developed that because of the operation of lightweight cars between heavy cars in trains, it was necessary for the Association of American Railroads to set up more detailed specifications to cover the construc- tion of all passenger-train cars built in the future, giving particular attention to prevention of damage from telescoping. A committee of the Association of American Railroads has recently developed these new specifications and they will probably govern all new construction of passenger cars. While these new specifications are generally based on the Railway Post Office specifications, they include some major changes: They provide for a centre-sill strength such that an 800,000-lb. load applied on line of draft will not produce any permanent deformation. The Railway Post Office specifications contained only a stress limita- tion and permitted the load application to be divided between the coupler line and the buffer line. This change will probably result in the ad- dition of more material than is now used in centre sills of lightweight cars designed with high centre sills and buffers, with little compensating benefit from added protection.
Light weight is almost a necessity for' high- speed operation in order to hold down the size and cost of power units, as well as the cost of opera- tion. This is particularly true with Diesel-electric locomotives with their high first cost. Experience indicates that 450 lb. per h.p. (including weight of locomotive) is a proper design ratio for high- speed operation. Some of the new trains have a power ratio as high as 550 lb. per h.p. but the maintenance costs appear to run higher on such trains. In order to secure satisfactory performance on high-speed schedules, it is necessary to have some reserve power in the locomotive because some delays are inevitable and extra power is needed to make up for lost time. While the schedules may indicate that maximum speeds of only about 90 m.p.h. are required, actual opera- tion requires at times speeds of 100 m.p.h. or even higher. This fact must be taken into considera- tion when designing locomotives and trains for this type of service.
Several of the early trains were built of aluminium alloys but in recent years the majority of them have been built of stainless steel or low- alloy high-tensile steel. The major claims for the stainless steel are lower weight due to higher physical properties, better welding by the auto- matic Shot-Weld process, and high resistance to corrosion. Stainless steel does not have to be given paint protection of any kind, which reduces both first cost and maintenance cost. Its polished surface gives an attractive modernistic appearance to the cars and is easily cleaned. In high-speed operation the sandblast effects of particles from the ballast or right of way damages paint finishes quite rapidly. The low-alloy high-tensile steel advocates claim that they secure equally low weights for lower costs.
It appears that a weight of about 100,000 lb. for an 80 ft. coach is entirely practicable with full safety to passengers. If too much space for extra luxuries is provided, part of the advantage of lightweight construotion is lost, as the important factor is the weight per passenger carried. Due to higher operating speeds, the design of passenger-car trucks is a most important factor. The former six-wheel trucks were not entirely satisfactory at these increased speeds, and doubt existed in the minds of some as to the possi- bility of securing good riding qualities with four- wheel trucks. The weights of the new car bodies were so low that only four axles were necessary to carry the load, affording further opportunity for weight reduction by the use of four-wheel trucks. Exhaustive experiments were made by various rail- roads and manufacturers resulting in the develop- ment of many new features of truck design with a decided improvement in riding characteristics. Among these new features were the use of softer springs with greater deflections, hydraulic shock absorbers to control both lateral motion and vertical spring reactions, multiple-spring systems in triple-bolster trucks, and roll stabilisers. The use of cylindrical tread contours on wheels to reduce the nosing of trucks, and the grinding of treads to secure true rotundity and concentrici ty, were both conducive to easy riding. Balancing of the wheels was also practised to some extent. In an effort to reduce noise in the cars, rubber or other semi-resilient materials have been introduced in various parts of the trucks, such as pedestals, spring seats, and centre plates. The mounting of the brake cylinders on the trucks instead of the body has also reduced the noise produced by the brakes. Improved insulation of car floors, as well as the sealing of windows, has also made a marked improvement, but there is still need for further noise elimination.
The introduction of high-speed lightweight trains brought many new problems in braking. The stopping of these trains within reasonable distance is a difficult problem. While the car weights are less, individual wheel loads are as high and in some cases (particularly with the articulated type) higher than with the old heavy cars. In order to reduce the stopping distance, there have been a number of changes from "former practice, such as truck mounting of brake cylinders which increases rigging efficiency, much higher braking ratios (some as high as 250 per cent.), decelakrons to reduce pressures as the train slows dOWIl and thus prevent sliding of wheels, automatic sanders acting only in emergency application, and electro- pneumatic control. In some cases the very high brake ratios resulted in considerable wheel and brake-shoe trouble. With all of these improve- ments there is still a question whether emergency stopping distances are as short as they should be. In both steam- and Diesel-powered lightweight trams, the locomotive weight is a large percentage of the train weight, but in most cases locomotives do not do their full share of the braking. The steam locomotive is particularly lacking for three reasons: First, there are often some unbraked wheels on engine trucks for operating safety; second, the large spread between light and loaded weight of renders makes it necessary to design braking power on the basis of light weight; and third, enginemen have to relieve engine brake pressure frequently to guard against the loosening of dnvmg tyres due to heating. The Diesel is better in that all wheels are braked and the spread between light and loaded weight is relatively small, but the srriall-diameter wheels are so highly loaded that the braking ratio must be limited in order to protect the wheels from damage. It would be advantageous if Diesel-electric locomotives had a supplementary dynamic electric brake such as is used in some electric locomotives as well as in the new experimental turbo-electric design.
The Diesel-electric locomotive is more commonly used in these new high-speed streamlined trains than is the steam locomotive. It is claimed by some that this is chiefly due to the interest of the public in a new type of power, but the users apparently' have. good engineering arguments to support their choice. The advantages claimed for the Diesel are: First, high availability; second rapid acceleration because of high tractive power at lower speeds; third, low maintenance costs; fourth, low fuel cost (usually less than half that of steam) ; fifth, lower rail stresses. The steam locomotive is 'less e:xpensive,' costing about $37 per h.p. However, It is harder on track at high speeds due to the dynamic augment produced by over- balance in the driving wheels. It appears that a radical change in the design of the steam locomotive is n~essary to make incapable of fully competmg with the Diesel m this service. The important objects of such redesign should be the securing of a more constant torque and the reduction of track punishment. Three outstanding locomo- tives of new design are under construction or in service, namely, the 5,000-h.p. turbo-electric being manufactured by .the General Electric Company for the Umon Pacific Railroad, the Baltimore and Ohio Railroad's four-cylinder engine, and the Pennsylvania Lines' four-cylinder high-speed engme. All of these new types are experimental but they indicate a trend towards a type of steam locomotive having more constant torque. A step still further in this direction is involved in a new Baltimore and Ohio design, which includes individual axle drive.
Manufacturers of Diesel-electric locomotives 'have an advantage in that they produce a practically standardised product and thus can reduce cost ./ through line production. On the other hand almost no two lots of steam locomotives are the same. Each order means a new design with re- sulting high costs for engineering and production. This also means higher cost for and larger stocks of repair parts. American railroads have made a marked advance in the standardisation of freight cars but there has always been strong opposition to any plan for standardisation of steam locomo- tives or passenger cars, due mainly to differences of opinion among different managements.
The riding quality of Diesels is better than that of steam locomotives They also provide smoother-riding trains as their high tractive effort at low speeds enables them to start and accelerate trains more quickly and smoothly.
Steam locomotives have an advantage in that more horse-power can be put in one unit. It may be noted that the increase in horse-power is secured with a lower percentage of increase in first cost and weight, that is, both the cost and weight per horse- power are lower for the 4-8-4 locomotives than for the 4-6-4 type. The maintenance cost per horse-power should also be somewhat lower for the 4-8-4 locomotive. It is true that any number of Diesel units can be coupled and controlled from one cab, but this increase in number of units means increased first cost and increased weight. A 2,500 h.p. Diesel unit would appear to be a desirable size for heavy service, particularly in mountainous territory, but this does not appear practicable at present.

Finally, engines Nos. 56-61 were renumbered Nos. 33-38 in 1922 and although No. 33 was scrapped in 1928 engines Nos. 34-38 were rebuilt with Midland Railway G.5 pattern (Belpaire) boilers in 1929, 1929, 1928, 1927 and 1928 respectively, becoming L.M.S. Nos. 2880-4 in 1930. The new boilers carried 160 lb. pressure and were fitted with Ross pop safety valves. New frames and new cylinders were also supplied, but the original cabs were retained. Fig. 47 shows No. 2884 as rebuilt. The eleven engines of this class taken over by the LMS were, therefore, Nos. 34-38, 51 and 67 to 71, and they became Nos. 2880 to 2890, as mentioned above. They were all scrapped between 1931 and 1933, the last three to go being Nos. 2881-3, so that the class is now extinct. These engines, which were all classed 1, were replaced on the Burnham Branch line by the Class "3" 0-6-0s to be mentioned hereafter. Fig. 48 is of interest in that it shows engine No. 68 (formerly No. 42) when it had become L.M.S. No. 2887 still with a John- son boiler but with a Deeley chimney of the same tall pattern as used on the 0-4-4 tank engines and 0-6-0s when reboilered with Deeley boilers.

L.N.E.R. 341
Thc following further V2 class (2-6-2) engines had been built at Darlington: Nos. 4840, 4841 and 4842, another V2 class, No. 4846, and a V3 (2-6-2T) No. 390, had been built at Doncaster, and two J50 class (0-6-0T) Nos. 595 and 598 had been built at Gorton. The following engines had been withdrawn: Nos. 824, 4-6-0 class BI5, No. 1874 4-4-0 class DI7, No. 4126 0-6-0 class J6, No, 1825 0-6-0 class J24, and No. 6178 0-8-0 class Q4.
On the 4 December a revised train service was brought into operation. Many additional trains were being run throughout the L.N.E.R. system and a mid-day service between London and Edinburgh was available again.
The passenger services on the Louth and Bardney line, the Horncastle branch and between Leeds (Central) and Barley had been restored as also had the L.M.S. Co.'s through trains between Broad Street and the GNR suburban lines. The entire L.N.E. passenger service between Derby (Friargate) and Burton on Trent, Uttoxeter and Stafford had however been withdrawn.

An early Taunton locomotive.. 341. illustration
Although the outside-cylinder 4-4-0 locomotive was, in its day, extremely popular in America, inside-connected engines of the same wheel arrangement were also built, but in comparatively small numbers. The reproduced illustration is of one constructed by the Taunton Locomotive Works, of Taunton, Mass. in 1852. This engine, which had cylinders 16 in. by 20 in., was in the service of the New London Northern Railway, a subsidiary of the Central Vermont Railway which in turn was a subsidiary of the Grand Trunk Railway. As a Westinghouse brake air pump was fitted, the photograph could not have been taken earlier than the 1870's, by this date a number of changes had probably been made to the engine, which carried the name T.W. Williams.

Several 0-6-0 goods engines had been reconditioned at Swindon and Eastleigh for service overseas,. including Nos. 2403, 2461, 2480, 2518 and 2533 which also did service abroad during 1914-18. No. 5089 Westminster Abbey, was a new 4-6-0 express engine, and the following had also been completed at Swindon Works, Nos. 3808 to 3813 (2-8-0), Nos. 2208 to 2210 (0-6-0), Nos. 3635 to 3645 (0-6-0PT), and Nos. 3104, 4130 to 4136 and 8108 (2-6-2T).

Fifteen 4-8-4 passenger and fast freight locomotives had been completed by the American Locomotive Company. They had cylinders 25 in in diameter, 6 ft. 8 in. driving wheels-with a tractive force of 63,800 lb. The tenders were carried on 14 wheels and carried 23,500 gallons of water.

Dublin University Engineering Society. 343
E.C. Bredin, Chief Mechanical Engineer, Great Southern Railways, delivered his inaugural address to a meeting of the members in Dublin on 17 November. The title of his lecture was "The Design of a Modern Locomotive," which had mainly for its subject the G.S.R. 4-6-0 3-cylinder 800 class locomotive. The design was referred to in detail and a number of interesting lantern slides were shown. Engines running on other lines were also described and illustrated and comparisons of two cylinder and multi-cylinder engines .were made. At the conclusion of the lecture R.G. Booth (presumably president) proposed and W.H. Morton seconded a vote of thanks. Mr. Morton also added some interesting remarks about the employment of Diesel locos. and railcars in Eire.

Bath have had their Westinghause hoses removed, but the air brake still operates the blacks an engine and tender and there is a "through" vacuum pipe far tl~e train. One or two minor differences are also visible, such as the extended cab roof and cased-in coal rails an N a. 2535, and the undisturbed positioning of the whistle an No. 2555. It is interesting to note that, in 1932 the farmer was at work with D. Marsh's sa fety-valves partially covered by a Stirling -casmg .
The story of the Small Vulcans is cample~ed by adding that, in 1905, D ..

WAR TIME LIGHTING. 347
The aim of railway engineers has been to restore white lighting of an intensity sufficient to afford a reasonably good reading light. This they have succeeded in doing by in- stalling shades specially designed to throw the light below the level of the carriage windows. To prevent the emission of any light it is necessary for the blinds of all carriage win- dows to be kept drawn throughout black-out times and a border of black paint has to be applied to the windows to prevent light showing behind the blinds.
What this involves can best be appreciated when it is remembered that the British railways have some 40,000 carriages with about 250,000 compartments. The total number of windows to be painted with a black band is about 1,500,000 and many of these have to be fitted with blinds or curtains. In each compartment at least two of the special shades have to be fitted to the lights, and it is . estimated that at least 500,000 shades ~ill have to be fitted.

Locomotives for India Again 347
N aur issue far March 15, 1937, we wrote criticising the suggestian put forward by an Indian contemporary that locomotives should be built in that country an the broad economic grounds that imparts were necessary far the pay- ment of exports and that in consequence if India failed to maintain a satisfactory basis of impart she would in the end find herself unable to sell her exportable surplus. We alsa commented .upan t~e stimulation to trade that would be expenenced If aut-of-date types of locomotive power were weeded out and replaced. The subject of ha me manufacture has recently received a further measure of prominence, bath in the Legislative Assembly as well as in the technical press, and we make no excuse far returmng to it on account of its own importance to the British locomotive- building industry. The idea of national self- sufficiency is no new one; it is 'a plain negation of economics as it fails to take into account the fact that trade must consist of buying as well as sell- ing on a. world-wide basis if the wealth af nations is to be maintained; it, unfortunately, is fa voured by certain schools of political thought and is in all probability one of the major causes of the present trouble. Let it be admitted at once that India can build her awn locomotives without any serious difficulty and has in fact already done sa to a very minor ex- tent, but if this is to become the national palicy- and here we quote our contemporary, "The Indian Railway Gazette" - "it would be necessary to ensure that the Legislative Assembly, in a mood of pardonable enthusiasm to foster locomotive construction, does not commit the country, as was done in the last decade, to expenditure far in excess of actual requirements." The corollary to the above quotation is that if once committed to this policy money will be spent like water by the Legislature in order to ensure its official success and that orders placed abroad will naturally cease.
It is perhaps an opportune moment to refer to recent locomotive building for India. The appaintment and Report of a substantial Committee recruited in this country and charged with the task of reviewing the design and alleged shortcornings of certain types of locomotives standardised by the Indian Railway Board is now history. Their remarks cannot be construed as encourag- ing to the existing arganisatian; in fact, the Rail- way Member (Sir Andrew Claw) summing up the debate an the Report in the Legislative Assembly (Sept. 11, 1939) said that the Committee had made it clear that in its opinion there was an error of judgment in neglecting the warning of consult- ing engineers and in proceeding without trial with the purchase of sa many engines at one time. Anather member had referred to this purchase as unwarranted and a huge waste of public money ; the outsider may well wander what the total sum will amount to when the whole matter is at last satisfactorily adjusted. We ourselves recall the description of two experimental engines for India read before the Institution of Locomotive Engineers on Dec. 15, 1937, in which the experi- mental alterations were so numerous that it would be practically impossible to trace any variation in result, whether good or bad, to its true source. It would seem therefore that there is room for im- provement in the ideas of the Board and we would like to suggest that as regards locomotives, design and manufacture should be left to the C.M.E. re- sponsible with the consulting engineers as a revis- ing authority. It is surely better to call in the great experience and knowledge available in tbis country at the beginning of things rather than at the end; in addition, the C.M.E. of the railway concerned is, and always must be, in closer con- tact with realities and requirements than a remote ami standardising board, however capable its members may be. We would remark in conclu- sion that the Report indicates in our opinion that in the absence of standard conditions of track and haulage the advantages of standard types of loco- motives intended to cover what really amounts to a continent are somewhat illusory

. AN OLD SWEDISH ENGINE. 348
The accompany photograph, taken by Mr. Sven Nygren of Vaxjo , Sweden, shows a link with the earliest days of railways in Scandinavia. As is well known, there were mining railways in Sweden before public railway trans- port was begun by the Government in 1856, and locomo- tives were built for these by the Munktells Machine Works in the early 'fifties and after. The second locomotive in Sweden, now preserved at Tom teboda, was a Munktells engine, built at Eskilstuna in I855. The example shown came from the same works in 1864, and is still at work on the K6ping-Uttersberg-Riddarhyttan Railway, which has the peculiar gauge of 3t ft. (Swedish) equal to 3 ft. 7 in.

Certain details appear to have been copied from early Beyer, Peacock locomotives for the Swedish State Rail- ways, such as the sandbox. The practice of placing the dome on the first ring, though also reminiscent of Beyer design. as in the Metropolitan tanks, was employed by Munktell from the first. The cab, the Coale safety-valves, and the spark-arresting chimney are later addition

Saltcoats Accident, L.M.S.R. 348-9
The Ministry of Transport issued the Report of its Inspector, Col. A.C. Trench, on the railway accident at Saltcoats on 5 August 1939, when the 12.30 Arran Boat Express from Glasgow (Central) to Ardrossan was derailed at Saltcoats with the loss of two lives, in addition to the two enginemen. The train consisted of seven non-corridor bogie coaches, all of which, except the rear coach, were fitted with shock-absorbing buffers. The locomotive was a standard class 4, 0-6-0 tender loco., No. 4315. The train was travelling on the former Caledonian Railway Co.'s Glasgow-Cathcart-Ardrossan line, constructed in the days of fierce competition with the Glasgow and South Western Railway for the Arran traffic but now only used for freight traffic, except during the summer services, when it is used for a few boat trains in connection with the Arran and Isle of Man steamers. There is a permanent speed restriction of 40 miles an hour on this line as between Lugton and Ardrossan. The Inspector finds that the train was travelling at not more than 30 miles per hour at the time of the accident, having just previously observed two temporary speed restrictions for subsidencies. As a result of the accident, the locomotive and its tender and five coaches left the rails on the outside of a slight curve immediately after passing over a road bridge, the locomotive and tender falling down the embankment, followed by three coaches—two coaches were derailed on the top of the embankment, and the two rear coaches remained on the rails. The two rear compartments of the second coach, and the three front compartments of the third coach were partially telescoped, and it was in these compartments that the casualties occurred—none of the passengers in the front coach were injured. The Report states that the track was in good condition, the outer rail was worn, but was perfectly safe for the speed-limit laid down. The evidence proved that a stone or stones had been placed on the outer rail at the point where marks on the rail showed that derailment had begun, a deposit of crushed stone 1i inch thick remaining on the rails after the whole train had passed over it, and that a piece of slag from the ballast had also been on the rail at a point 55 yards before the mark of derailment. A certain amount of trespassing along the line had been customary—especially by children—access to the line being obtained at the foot of the abutment of the road bridge mentioned above. The Inspector clears the enginemen of all blame, and finds that the derailment was due to the stones placed on the line and fixes the responsibility for the accident on those who placed the obstruction on the line.

Continued from page 283). Group 2. APPLEBY WORKS LOCOMO- TIVES (TILL 1934). The locomotive fleet of the Appleby Ironworks, before its association with the Frodingham Works in 1912, comprised eight units as follows:- Appleby Loco. Old No. 1. The first loco., probably dating from the open- ing of the works in 1877, was purchased from the Yorkshire Engine Co. and was of four-wheeled saddle-tank type, with "13 inch" outside cylin- ders and a working pressure of 140 1b. per sq. in. This loco. bore the name The Old Mare and was sold to a purchaser in South Wales, about the end of the war.
Appleby Loco. Old No. 2.
The second loco. was of second-hand origin and early date. Built by the Hunslet Engine Co., it was of six-coupled, saddle-tank type, with a work- ing pressure of 160 lb. per sq. in. and "14 inch" inside cylinders. For its time this loco. was of advanced and powerful type. For many years it was used to handle ironstone traffic on the furnace "drops" or bunker inclines. During the mid- nineteen-twenties, it was scrapped Appleby Loco. Old No. 3. The third loco. was purchased from Andrew Barclay, Sons &Co. about 1884, and was of four- wheeled, saddle-tank type, with "13 inch" out- side cylinders and a working pressure of 140 lb. per sq. in. Old No. 3 was sold about the end of the war period, apparently to the Rather Vale Collieries, now another section of the United Steel Companies L td. Appleby Loco. Old No. 4. The fourth loco. was purchased from the Huns- let Engine Co., about 1890. Like all later addi- . tions to the fleet, it was of six-coupled type and provided with an adequate cab. The working pressure was 140 lb. per sq. in., and the inside cylinders were of 13 in. diameter. The loco. was scrapped about 1927. Appleby Locos., Old No. 5 and Old No. 6. The fifth loco. (No. 5, Pontypridd) and the sixth (No. 6, Pendleton) were both acquired second-hand and are reputed to have previously served constructional work for the Manchester Ship Canal. In this case their arrival at Appleby was probably soon after the completion of the canal in 1894. Built by the Hunslet Engine Co., both were of six-coupled, saddle-tank type, with working pressures of 140 lb. per sq. in., and inside cylinders of 14 inch diameter. Scrapping took place during the war in the case of No. 6, and and towards 1927 in the case of No. 5. Appleby Loco. Old. No. 7. The next loco. ( o. 7, Roseneath) was bought second-hand about 1900. Built by the Hunslet Engine Co., it was of six-coupled, saddle-tank type, with a working pressure of 140 lb. per sq. in., and inside cylinders of 13 inch diameter. The date of building is unknown, but scrapping took place about 1927. Appleby Loco. No. 8 (No. 108, from 1933, No. 66 from 1938). The eighth loco. was purchased from the Huns- let Engine Co., in 1909. Details are listed below:- Steam pressure 160 lb. per sq. in. Tubes 130 at 11 in. Total heating surface (tube and firebox) 528 sq. ft. Grate area 8 sq. ft. Tank 550 galls. Cylinders (inside type) Diameter 14 in. Stroke 18 in. Wheels (six-coupled) Diam 3 ft. 2 in. Wheelbase IQ ft. 9 in. Journals 5! in. by 6! in. and 6! in. by 61 in. Frame Thickness I in. Tractive effort (calculated at 75 per cent.) II,qI lb. Gross weight (full working order) 27.25 tons Adhesion ratio (gross weight/tractive effort) 5.5 Appleby No. 8 was smaller than contemporary units at Frodingham. The loco. has proved speedy for lighter duties, however, and is now retained in the amalgamated fleet. (To be continued).

or 265 h.p. and 655 h.p. respectively, this energy decreasing to zero within 24.5 sec. and 62 sec. re- spectively. When holding the axle on a down- ward grade of 1 in 50 and 1 in 25 at a constant speed of 50 m.p.h., the energy to be dealt with is 39.7 h.p. and 92.5 h.p., or 28 B.Th. . and 65. B. Th. U. respectively. As the tyre surface with nor- mal 3 ft. wheels is 450 sq. in., and the shoe surface 2 x 46.5 = 93 sq. in., and as furthermore the heat conductivity of steel is about 33.6 B.Th.U. (f t.):' (hr)-I(deg.F)-l the heat difference within the tyre when stopping from 125 m.p.h., and thus dissipat- 36000 x 12 ing 655 h.p. will be = 236°F. per ( 450 + 93) x 33.6 inch. As indicated by the above general calcula- tion the stresses involved due to heating of the wheel can lead to deformation with resultant cracks in the wheel rim and in this respect the tests made at the University of Illinois are of interest (10). The wheels used were chilled units 33 in. in dia. and weighing 700 to 750 lb., the brake shoes being plain unflanged cast-iron ones with chilled faces, while one wheel was subject to shoe pressures of 1,000, 1,500, 2,000, 3,000 and 4,000 lb., the rest was subject to a pressure of 3,000 lb. only. With most of the tests the rim speed was kept con- stant at 25 m.p.h., and the shoe applied continu- ously for 48 minutes, this combination of speed and duration being equivalent to a wheel tread travel of 20 miles. The tests have shown that while at a pressure of 1,000 lb. the shoe wear was 0.244 lb. per 100 millions ft. lb. of work, this figure increased to 0.53 and 1.091 lb. at a shoe pressure of 2,000 and 4,000 respectively, this indi- cating the advantage of employing smaller shoe unit pressure. While the first tests were made with a wheel having a diameter variation of not over 0.001 of an inch, difficulty was experienced at shoe pressures of 1,000 and 1,500 lb., as eccentricity of the tread developed due to unequal heating. When hot the wheel was out of round up to 0.01 inch, this caused unequal distribution of heat, as the shoe did more work on the high than on the low section of the tread. After a few applica- tions at 2,000 lb., shoe material was deposited at several places on the wheel tread and glazed spots developed in these places. They caused unequal heat distribution in the wheel, probably due to a lower coefficient of friction at these spots, leading to a deformation of the wheel. A few small checks developed during the tests at 1,000 and 1,500 lb., while a few more, together with a few small cracks, were produced during 2,000 lb. shoe pres- sure tests. After the 3,000 lb. tests, a large num- ber of heat checks and cracks were found on the wheel tread, thirty-two cracks being longer than 2! in., the condemning limit specified by the Association of American Railroads. After the 4,000 lb. tests 92 cracks over 2i in. long were found, and although none extended into the throat or flange some 16 ran to the outside of the wheel rim. As up to the present no method is available whereby the surface temperature of a revolving wheel may be measured with any degree of accu- racy, no reliable conclusions can be drawn as to the relation of the surface temperature and wheel failures. Measurements made with thermo- couples inserted in the wheel t in. below centre of tread showed temperatures up to 280 and 6900 F. when applying a shoe pressure of 1,000 and 3,000 lb. respectively, the hub temperature for the same tes ts being 115 and 2150 degrees F . respectively. After a stop the wheel rim cooled rapidly while the temperature of the hub and the surrounding plate of the wheel increased within 20 and 30 minutes to 140 and 3400 F. respecti vel y, this being due to the fact that the rate of heat transfer from the wheel plate. is considered less at a stop than when runnmg. The maximum radial tensile strains shown by the tests occurred always at the outer face of the wheel, near the curved junction of the plate with the hub. In all tests the maximum radial strain produced was a tensile strain of 23,300 lb. per sq. in., which occurred when applying brake pressure of 4,000 lb. for 50 minutes at a speed of 15 m.p.h., the distribution and relative magnitude of the radial strain at both plate faces of the wheel being shown by Fig. 8.

The High Level Belt Railway and the New Stations in Amsterdam By L. DERENS, 354-6
D uiu G the night of October 15 the old Weesperpoort station of Amsterdam finally closed and its activities transferred to the new Amstelstation opened early next day. Since December 28, 1843, when it was opened, as the terminus of the then broad gauge Dutch Rhenish Railway, it has performed its task and witnessed the many changes of traffic conditions and last but not least, has endured the drastic alterations for temporarily adapting it to electric traction, pending the completion of the Amstel- station. Although not reaching its own centenary, this historic building witnessed the ce~tenary cele- bration of the Dutch railways, on which occasion the front of its arched roof was suitably decora- ted, as shown in Fig. 1, with a wooden winged wheel mounted on the national flag, flanked on both sides by the initials N .5. with the centenary dates. The last train on the night of October 15 was an electric train from Utrecht leaving for the Cen- tral station at 0.21 a.m. An official ceremony with representatives of the railway compan~ and of the city of Amsterdam present, took place m the train. The enthusiasm of the Amsterdam people was remarkable thousands gathered to witness the departure of the last train, the station being filled. The police were unable to withhold the crowds from passing the ticket barners on the second platform at which the train arrived. The d~IVer was carried on the shoulders of the enthusiasts from the rear to the front of the twelve-car train, where he added his tribute to others, decorating the head of it. At last amidst cheers and noise from exploding detonators on the track the train

S.W. Johnson. W.B. Thompson
On p. 315 Ellis stated that the last Midland engme painted green was.a tank engine built in 1881. May I say that the green paint survived a little longer? The twenty express engines built in 1882, Nos. 1562-1571, which were fitted with the vacuum brake and ran between London and Nottingham, and Nos. 1572-1581, which had the Westinghouse brake and worked south from Carlisle, were all painted green when new. I had a trip from Carlisle on No. 1577; and I also remember being on a rebuilt Kirtley goods engme, No. 494, at Rugby early in 1883, which had recently come from Derby and was painted green.
The red paint was said to be cheaper; but it seemed a pity that the green was abandoned, for the engines never looked so well after the change.
Beauty is a matter of personal impression, but I think most people would agree with me in saying that Johnson was the greatest artist, not even exceptmg Joseph Beattie or Stroudley, that the locomotive department of a British railway has ever produced. For myself, I consider that his 60 class of express engines built towards the close of the last century were the most beautiful engines I have ever seen on any railway in the world. To those of us who remember the elegance of design and the spotless cleanli- ness of the Johnson engines it is a sad experience to travel on the Midland line to-day.

S.W. Johnson. James Bell.
Re. C. Hamilton Ellis's Famous Locomotive Engineers: is he is right in ascribing to S.W. Johnson any share in the design of N.B.R. Nos. 382-393. I cannot distinguish any particularly Johnsonian features in the design of these engines and the fact that they were built after his regime as Loco. Supt. at Cowlairs had ended does not favour the supposition that the design was his. Moreover, when they first appeared in 1866 they embodied features which were already familiar on the N.B.R. The design of frame was precisely similar in outward appearance to the frames of Nos. 90-95, built in 1861 by Neilson and Co. Later on, in 1865, exactly the same frame appears in the N.B. series Nos. 341-346 built by Dubs in that year. In all these classes the design of splashers. side-sheets, and stormboards are much alike and came, one would say, from the same hand.
As a boy I knew No. 393 well, prior to her rebuilding. At that time she had lost her original funnel which had been replaced by one of Mr. Wheatley's stove-pipes, but she still retained her wealth of brass beading. When new she must have been a very handsome engine. A clue to the authorship of the design might be found in the fact that the 382 class all had pull-out regulators. The other classes I mention may have had these regulators also. I cannot say; but I am absolutely certain that the 382 class had them.
At the time when I first knew 393 she had long come down from express rank, having been superseded by the Wheatley,· Drummond , and Holmes engines, but she was still a speedy and reliable engine, remarkably silent, and easy on coal and oil and Mr. Johnson, if he had anything to do with her design, had reason to be proud of his handiwork, Signed Inspector, L.N.E.Rly., Edinburgh.

Early Pullman cars. Stephenson Y. Knight. 357
Re Canon S.B. Fellows and J. Pelham Maitland's articles on the above have been of very interesting reading to me seeing that at that time my late father, the then General Manager of the L.E. & S.C.R., J.P. Knight, and Allport of the Midland Railway were the pioneers of the Pullman mode of travelling in the United Kingdom. My own recollections of these splendid trams go back to r883 when as a small lad I can well remember being taken to and from Brighton for a trip in the Pullman train. The early Pullmans were, as the Rev. Fellows says, of the open end balcony type of build; they were 60 feet each long, and one could walk the whole length of the train as wooden platforms covering the connections between the cars were provided, the cars being coupled with Stroudley's patent "Close coupling device" very ably set out in detail in Barry's Railway Mechanics. There were thirty lights in the cars and the current for these came from thirty-four Faure accumulators, charged in the first instance at a depot in the Strand somewhere near the Tivoli Music Hall. Afterwards Houghton, the Electrical Engineer to the Brighton Railway, put up a small charging unit at Victoria Station for this purpose and here the accumulators continued to be charged until Houghton brought out and invented his device for charging the batteries from a generator, belt driven from the axle of the car. The cost of the Pullman Train was about £12,000, and at the time (1881) it was the most luxurious of its kind running in Europe. The cars were fitted with what was then quite an innovation by way of blinds for the windows, they were sprung supported and could be lowered or raised to any desired position by the passenger. The train was also fitted with the Stroudley and Russbridge Electric Communication which had just then been introduced on the Brighton Railway. Henry Marks was the conductor of the train and he afterwards became the manager of the Pullman Car Company. Two other well known conductors of Pullmans on the L.B. & S.C.R. went by the names of "Nutmeg" and "Fussy," but to this day I am unable to trace the origin of these names. Mr. Snow must also be remembered for he was for many years in charge of the Pullman running in the Newhaven boat train.
The Rev. Fellows does not mention the standard livery of the cars. They were finished in a deep umber brown, with black and gold lining. The names of the cars were Albert Edward, Victoria, Beatrice, and Louise. When the 1888 Pullman Vestibuled Train made its appearance the old Pullman Train was divided up and the cars put into service on different trains running between London and Brighton; for many years, in fact well into the 'nineties [1890s], Albert Edward and Victoria ran in the 5 p.m. down and the 08.45 up expresses to and from Brighton. "Nutmeg" and "Fussy" had charge of these cars, and I remember their very courteous attention. Hot breakfasts of a limited menu could be had on the 08.45. train from Brighton, teas could always be served, also other liquid refreshments too numerous to mention.
About the year 1879, a Pullman Drawing Room Car was run in the 15.55 ex Victoria; this train ran to Portsmouth Harbour, having a through connection to the Isle of Wight, reaching Ventnor at 20.24. The Pullman adventure in this respect did not turn out to be a success and it was withdrawn.

Timothy Hackworth and the locomotive. A.V. Green, 357-8
Re books James Watt, Engineer and Craftsman, by H.W. Dickinson, and the other Timothy Hackworth and the Locomotive by R. Young. Kindly allow me through the "Locomotive" to draw attention to a remarkable discrepancy in these two books. On page 6 of "Timothy Hackworth" note the portrait entitled William . Murdoch by courtesy of the Secretary, James Watt Centenary Memorial. Then compare Plate VIII on page 86 of James Watt, Craftsman, which claims to be that of Matthew Boulton, from the oil painting by Wm. Beechy, in possession of the Boulton family. facing. page 114 of the same book we have Plate X representing Wiilliam Murdoch, from an oil painting by Graham Gilbert, by permission of the Museum and Art Gallery Committee of the Corporation of Birmingham. Where does the error lie? I am inclined to the belief that it is in Mr. Young's book. On the other hand, it is strange that neither Mr. Young nor his friendly critics observed such a mistake.
The matter I trust, through your good offices, will be brought under notice of such bodies as the Stephenson and Newcomen Societies, as well as the Institution of Locomotive Engineers, etc. It is of importance that posterity be furnished with accurate history, and I shall endeavour to do my share in this respect. If I can furnish information about Australasian railways to bona-fide members of engineering and historical societies, I shall deem it a pleasure and a duty to help them:

The railcar 1847-1937.- R.W. Kidner. Sidcup: Oakwood Press.
Yet another of the useful little handbooks, for which the Oakwood Press has now became noted, has been issued, and this time the subject treated is less known than that of any previous booklets. In fact, very little of a historical nature concerning railcars has hitherto been published and the work under notice gives in a compact. form and easy of reference many details which cannot be found elsewhere. Dimensions, dates and many other particulars are given of most of the cars that have run on British railways, and there is also a brief survey of the development of the railcar overseas. It is very profusely illustrated, but whilst the half tone blocks are excellent, the line drawings are rather sketchy. The author is in error with regard to Ariel's Girdle, which after being shown in the Great Exhibition of 1851, was purchased, not by the Eastern Counties Ry., but by the Eastern Union who used it on the Hadleigh branch. At a later date it passed into the hands of the E.C.R. and it is to this period that the details of its subsequent history belong.

Coach painting. 358
At the annual meeting of the American Car Department Officers' Association held in October a number of useful reports were presented including one on passenger car painting. The American railways are now more than ever endeavouring to have all equipment meet with popular approval. As a result over 11,500 coaches were equipped with air conditioning systems. At the end of 1938 85 streamlined trains had been put into service and more have been added since. Exterior decoration has been revolutionised and car builders were employing new metals, allovs and other materials that require different treatment. There are red cars, grey ones, blue, green, yellow and other colours to attract the eye. Owing to their high speed and desire for smartness, constant cleaning is necessary to keep them spick and span. A problem is to keep the car, clean without damaging their finish as most of the chemical compounds used for cleaning cause streaks and blemishes.
