Institution of Mechanical Engineers: Abstract of paper relative
to "High,Pressure Locomotives," and to L. &. N.E. Ry. locomotive
No. 10,000, read hy Mr. H. N. Gresley, C.B.E. 38-9.
In his paper on "High-Pressure Locomotives," read on Friday evening, January 23, before the Institution of Mechanical Engineers, Mr. H. N. Gresley, chief mechanical engineer of the L. & N.E. Ry., described some special features of considerable interest relative to the water-tube boiler of the high-pressure engine No. 10,000, which was completed to his designs at the end of 1929 at the Darlington Works. See also page 113 et seq for details of valve gear.
New locomotives for the San Paulo Ry. 40-1. 2 illus.
The 5ft 3in gauge railway connected the port of Santos with Jundiahy where a junction was made with the Paulista Railway: a feature of the railway was ths sharp rise of 800m via the Serra inclines which were cable operated. Two new locomotives were described: one of two twin axle cable gripping locomotives for operating on the Serra incline supplied by Robert Stephenson & Co., and five 2-8-4T locomotives built by North British for hauling freight.

Past and Present Crewe Pupils and Premiums Annual Dinner. 41.
This year's dinner, the forty-first, to be held at the Mayfair Hotel on Friday, April 17, at 7-30 p.m. for 8 o'clock. The chairman will be Mr. H. N. Gresley, C.B.E., chief mechanical engineer of the London & North Eastern Ry., who served his time at Crewe Works, and the guest of honour will be Sir Josiah Stamp, President of the London, Midland & Scottish Ry. Mr. Reginald Terrell, 64 Victoria Street, Westminster, S. W.l, is hon. secretary for the.dinner, and he will be very glad to hear from any past Crewe pupils and premiums who would like to attend.
London, Midland & Scottish Ry. (L. & N.W. Section). 41.
The first ten of the new 0-8-0 standard superheater freight engines now being turned out at Crewe are for service on the Central Division (L. & Y. Secticn). Nos. 9600-4 have already been despatched, while Nos. 9605-6 are at present being broken in from the South shed. Three additional 2-6-2 passenger tank engines ex Derby have been delivered, Nos. 15517-9. The three-cylinder 4-6-0 No. 5902 Sir Frank Ree has been sent to Longsight for trial against one of the rebuilt 5X "Claughtons." Messrs. Hudswell, Clarke & Co., Leeds, have recently supplied a smaIl Diesel locomotive to Crewe Works. It replaces one of the 18-in. gauge steam tramway engines, all of which have now been broken up with the exception of two, viz., Pet (built 1862) and Billy (built 1875). It is understood that the older of these is to be withdrawn for preservation.
No. 6646 and 6679, 5 ft. 6 in.., 2-4-2 class, have been adapted for working motor trains. Engines recently altered to suit the Midland loading gauge include "Prince of Wales" class No. 5638 and "G1" class No. 9123. 18-in. goods No. 8352 has had the footplate raised owing to the provision of a larger tender than that with which it was previously fitted.
The 2-4-0 "Jumbos" are now reduced to twenty-two, including four only of the 6-ft. class. The total withdrawn during 1930 was thirteen, as against eight in 1929. In view of the approaching doom of this once famous class, it is to be hoped that one of them may be spared for preservation at Crewe. The celebrated Hardwicke, which is stilI running, would appear to be a very appropriate example for that purpose. As is weIl known, this engine achieved considerable fame during the great railway race of 1895, its final run from Crewe to Carlisle, 141¼ miles, being covered in 126 minutes, or at an average speed of 67¼ miles per hour.

See also Locomotive Mag., 1909 and 1910, 16, 58 and 246. Notes that the sledge or slipper brakes had to be changed. These had consisted of heavy brake shoes having A-shaped castings at the top, guided in angular brackets in the hornplate brace rods. The shoes were pivoted to beams linked to the axle boxes. Bodmer claimed this design was an improvement on the tender brake rigging shown on page 113 of THE LOCOMOTIVE MAGAZINE of June 15, 1909. When the shoes were raised, as shown, they hung clear of the rails. When, by means of the usual brake mechanism, the fireman lowered the shoes, they dragged along the rails. Their action was violent and caused derailments. Sometimes the shoes ran foul of the points. These brakes were soon abandoned. Sledge brakes were tried on the tank engines working the Ghat inclines of the Great Indian Peninsula Ry. Bodmer considered these goods engines as "powerful," and a description will be found in Sekon's Evolution of the Steam Locomotive, London, 1899. At least, some of them were built by Sharp, Roberts & Co., of Manchester, for the Manchester and Sheffield Ry. .
The Institution of Locomotive Engineers (London).
A Paper on "The Development of the Piston Valve to improve Steam Distribution" was read by Mr. D.W. Sanford, B.A., Member, at the general meeting held at Denison House on January 29. Mr. H. Kelway-Bamber, president, was in the chair. After making suitable reference to the death of the late Hon. General Secretary, Mr. Jos. C. Sykes, the chairman called on Mr. Sanford for his paper. See J. Instn Loco. Engrs., 1931, 21 Paper 273.
After considering the reasons which led to the introduction of piston valves the author directed attention to three features of interest connected with the flat slide valve which the piston valve had replaced: (1) the desirability of keeping the travel short, to avoid friction and reduce wear, notwithstanding the fact that this gave less satisfactory steam distribution; (2) to obviate the disadvantage of having large valves on which the steam pressure acted it was customary to bring the ports close together and make them long, thus increasing the clearance volume and the surfaces on which interchanges of heat between the metal of the cylinder casting and steam took place; (3) the advantage that the flat valve took up its own wear and, provided lubrication was satisfactory, the fact that it remained steam tight throughout its service. With piston valves the first two defects mentioned were overcome, although full advantage was not always taken, but as regards the third leakage quite a different problem presented itself. The author showed the effect of leakage by diagrams on the screen and then proceeded to give illustrations of the best arrangements of packing rings to prevent such losses. The employment of a number of narrow rings in place of one wide one he considered advisable.

Lists Locomotive Superintendents: Thomas Simpson who died in an accident at Maesycwmmer in June 1869; Thomas Mason for the next four years; Charles Long until 1888; George C. Owen who was found decapitated on 18 April 1909; James Dunbar until his death on 26 February 1922, and H.F.H. Gibson who acted as locomotive superintentend until the Railway Grouping. Four locomotives were available when first section of line opened. Two 0-6-0 tender locomotives were supplied by Sharp Stewart in 1863 (WN 1408-9) and were named Alexandra and Brecknock. Two Sharp 0-6-0STs were also supplied for shunting and banking (WN 1471-2): these were named Jupiter and Pandora.
Two engines ordered by the "Old" Rumney were also taken into B&M stock: these were Sharp 0-6-0 tender engines WN 1587-8 and named Caerleon and Caerphilly.

It was demonstrated on the Harpenden to Hemel Hempstead and is shown at Redbourn. The bodywork was constructed by Cravens.
Southern Ry. Literary and Debating Society. 58
Lecture on the locomotives of the Southern Ry. was given by J. Clayton, on Wednesday evening, 21 January 1931. R.E.L. Maunsell presided. The development of the later types of locomotives in service on the Southern Ry. was described and illustrated with photographs and drawings. In opening the discussion, the chairman referred to the 107 different types of locomotives handed over at the time of grouping, and spoke of the benefits which had accrued from standardisation. At the close of the lecture a number of questions were asked by members of the large audience, and much interesting information regarding Southern Ry. locomotives was given in the replies.
The Railway Club. 58.
There was a large attendance of members at the January meeting of the Railway Club, when Lord Monkswell read a paper on Railway reform. While admitting that great advances had been made in the adoption of safety appliances, he contended that the railways were suffering from arrested development, and that, to take the instance of speed alone, the progress made during the last fifty years was far short of what it should have been, while many of the reforms had only been adopted after years of agitation on the part of users. He condemned the wages settlement forced on the railways by the Government after the War as deplorable, but considered that the railway remained the most efficient system of transport, and that the solution of the present position was for the directors to organise the shareholders and strike out a firm line. At the meeting held on February 6, Mr. W. A. Willox, vice-president, gave the Presidential address, in the unavoidable absence of Mr. Kenneth Brown, president. Mr. Willox took as his subject "The Future of British Railways," and made a number of pertinent and thoughtful suggestions as to what might be done so that, from the public point of view, the railways might appear more efficient, more punctual, and more attractive.

The sixth annual dinner of the Southern Ry. Eastern Divisional Locomotive
Running Department 60.
Held at Strand Palace Hotel on Wednesday, 28 January 1931. The gathering, which numbered over 180, was presided over by Mr. D. Sheppy, Eastern Divisional Locomotive Superintendent, who was supported by Mr. A. D. Jones, O.B.E., M.V.O., Mr. G. Oxley, Mr. G. Pullen, and Mr. E. W. Trangmar. After the loyal toast had been honoured Mr. W. Cole gave "The Chairman and the Eastern Division," to which Mr. Sheppy responded. The usual toasts having been given and responded to the company then proceeded to enjoy, an excellent musical programme provided by "The Checks" concert party, which, to judge from the generous applause, was highly appreciated.
[W.A. Stanier lecture]. 60
A comprehensive and interesting lecture was given by Mr. W. A. Stanier, M.I.Mech.E., Principal Assistant to the Chief Mechanical Engineer, G.W. Ry., before the G.W.Ry. (London) Lecture and Debating Society, at Paddington, on 15 January 1931. Mr. C.E. Lloyd, a director, and also an engineer, occupied the chair. Mr. Stanier's lecture was illustrated by many lantern slides, and the various locomotive types introduced by five successive C.M.E.'s were shown, and their work detailed. Mention was made of the development of the many types, from the old broad gauge North Star to the present-day e»press engines, including the "De Glehn" compounds, The Great Bear, "Castles" and "Kings."
[XA and XB type engines for India]. 60
Order placed with Vulcan Foundry by the India Store Department for seventeen "XA" type engines, ten of which are for the Great Indian Peninsula Ry. and seven for the North Western Ry., also ten "XB" type for the East Indian Ry., and ten "XC" type for the North Western Ry.

There was also a novel four-wheel tipping wagon.
[Sir Charles Cust]. 65
Sir Charles Cust, who died recently, was a personal friend. of H.M. The King, and on one occasion acted as driver on the L. & N.W. Ry., and the "Claughton" locomotive bearing his name was frequently used to draw the Royal Train.
L. & N.E. RY. 65.
The following "Sentinel" locomotives were recently delivered to the L. & N.E. Ry.: Nos. 18, 21, 23, 35, 42, 45, 49, 55, 60 to 65, 78, 87, 94, 96, 98. They are all in the Southern area, except 45 (Sentinel 8332), which is at York. Several of the later ones are on the Great Eastern section, but No. 55 is at Hitchin and No. 42 at Bidston. In addition to No. 4737, which was transferred to the Great Eastern section some months ago, further "N2" tanks have come south from Scotland and are working from Hatfield shed. Nos. 4730, 2686, and 2689 are there, but have not yet been fitted with condensing gear. The engine shed at Thirsk has been closed and the four engines stabled there are now at Northallerton depot.

Wastage of locomotive firebox stays and plates. 67-8. 3 diagrs.
The following conclusions were arrived at from the experiments made: .
I. The wastage of stayheads is primarily due to oxidation of the copper, but the effect of oxidation alone is generally not serious under dry conditions; it becomes so under the influence of leakage which causes the detachment, leading to removal of the otherwise hard and tenacious oxide scale.
2. The composition of the atmosphere of the firebox varies within wide limits; it is generally oxidising in character, although never containing high percentages of free oxygen, and is hardly ever, if at all, markedly reducing.
3. The surface temperature of stayheads has not been found to exceed 350°C., and is generally not over 300°C., even in the hottest part of the box.
4. Leakage from the stays is the result of plastic deformation of the plate and stay under thermal stresses set up in working.
Notes extracted from paper on "Properties of Locomotive Firebox Stays and Plates," by Messrs. Hudson, Herbert, Ball and Bucknall, read before the Institute of Metals at Dusseldorf.
London & North Eastern Ry. 68
No. 2822 Alnwick Castle and 2823 Lambton Castle, of the "Sandringham" class, have been completed at Darlington Works. No. 4349 is a further G.N. Ry. 4-4-0 working on the Tebay line. No. 2118, a class T 0-8-0, is stationed at Kirkby Stephen, working ore traffic from Penrith. As the eight-coupled engines are not allowed over Deepdale and Belah viaducts, this engine was taken over the Stainmoor summit with empty boiler and tender, on a goods train.
Whistle reflector, Missouri, Kansas & Texas RR. 69. 2 illus.
Photograph shows locomotive, No. 404, of the M.K.T. RR., provided with a novel form of whistle or sound reflecting device which has been used for securing some interesting data concerning the intensity of sound waves emitted from a locomotive whistle. As will be seen from the photograph, the whistle is placed horizontally within a parabolic reflector, cast of "lynite" and located immediately in front of the chimney. The object is to secure a more direct and intense sound from the whistle when used on approaching highway level crossings to warn motorists and others of the near approach of a train. Focussed ahead in this manner there is a corresponding reduction in sound or noise heard by the engine-men and passengers in the train behind, as well as those who may be in the neighbourhood on either side of the track. To measure the effect of the arrangement shown, an "Oscillograph" was used to record the tests.
[Messrs. Willoughby's model locomotive]. 69
Referring to description of Willoughby's model locomotive in the January issue (p. 33), it should have been stated that this is a reconstruction and thorough rebuild of a model said to have been made for the late Sir David Salamans, who used it for some signalling experiments. About 1885 the model was on view in Mr. C. Baker's shop in Holborn, and more recently at an amusement arcade at Blackpool. When the engine was on view at the last "Model Engineer" exhibition, parts of the original which had been scrapped were also shown: credit is due to Messrs. Willoughby for rebuilding the engine and all the good work they have put into it. A misprint occurred in the dimension given for the length of the steam port; this should be 7/32 in. wide.
Tank Locomotive, North British Ry. 70. illus.
0-4-2WT No. 20, illustrated was first of a class of eight tank engines, designed by W. Hurst, locomotive superintendent of the N.B. Ry. and built at St. Margaret's Works, Edinburgh: 1857, Nos. 20 and 22; 1860, Nos. 29 and 49; 1861, No. 96, and in 1862, Nos. 97, 98 and 99. As built, they had coupled wheels 4 ft. 9 in. dia. and cylinders 12 in. dia. by 18 in. stroke. They were rebuilt later with 13 in. dia. cylinders, and scrapped in the early 1880s by Wheatley. No. 20 was the third engine built at St. Margaret's, the previous two being single-driver tanks of similar design. No. 20 at one time worked the Jedburgh and Kelso service, and the driver in the photograph was Archie Lightbody, driver on this branch and was over seventy years of age when he retired. His son succeeded him on the same turn. One of these engines was involved in a disastrous collision at Penicuik, on the Peebles line, on October 29, 1863.
Model "Mail" class locomotive built by Messrs. Willoughby. G. Geo. Woodcock.
Re Model "Mail" class locomotive built by Willoughby: it seems a pity that such a fine piece of work should be inaccurate as regards relationship to prototype in several ways. The "Mail" class as designed by Cudworth in 1861 had no cab, but a plain waisted weather-board; they also were fitted with Salter safety valves on the dome and were, of course, tender engines, not tanks.See also letter from G.S. Willoughby on p. 106.
Locomotives of the L.M.S. past and present. London:
Locomotive Publishing Co. Ltd.
This very interesting and excellently printed book has just been issued, and in it is given a concise history of each of the railways constituting the L.M.S. group, though necessarily, on account of space, only brief mention can be made of the smaller companies absorbed. There are eight colour plates and seventy-eight illustrations of locomotives, past and present, all of which are exceptionally well reproduced. A number of marginal pen and ink sketches of early locomotives enhance the interest, whilst at the head of each chapter is the "coat of arms" of the company being dealt with. For those who are interested there is a list of named engines, followed by a table of leading dimensions of the various L.M. & S. Ry. classes of standard locomotives, as well as the leading types of the constituent companies, forming a valuable adjunct to an attractive publication which should find a place in the library of every railway enthusiast.
Railway carriage and wagon handbook. London: Locomotive Publishing
Co. Ltd. 274 pages, cloth.
Comprehensive book of reference covers a large field of information on a subject which has hitherto sadly lacked attention. It is a revised and much enlarged edition of the Railway Carriage and Wagon Builder's Pocket Book, brought up to date. The book opens with a section on carriage design and construction, followed by chapters on the varieties of timber in general use. Then there are sections on the trimming of carriage seats and backs; painting, with notes on painters' materials, followed by articles on the use of aluminium for panelling; fabric-covered bodies and enamelled-iron panels. There is a lengthy section on train lighting, heating, and ventilation, followed by extracts from the British standard specifications of materials used in carriage and wagon construction, including axles, tyres, springs, steel castings, plates, angles, and rivets. Space is devoted to the maintenance of carriage stock, as well as the examining and progressive repair of coaching stock in the shops. Chapters dealing with the design and constructional details of British standard wagons include a section on the mass production of steel wagons. Wheels, axles, axleboxes, buffing and drawgear, centre couplers, bearing springs, and metals and alloys for bearings are discussed in turn. Railway gauges and construction gauges. vacuum and air brakes, and roller bearings receive attention in the final sections. Nearly fifty pages of quite useful tables and miscellaneous shop notes are included. The book is well iliustrated, and is printed on good paper in clear type.

Metropolitan-Vickers Electrical Co. Ltd., Long Service Association.
The staff canteen at the Trafford Park Works was the scene of the annual meeting of the association on Monday, February 23. Sir Philip A M. Nash, president of the association, was unfortunately unable to take the chair owing to illness, and his place was taken by G.E. Bailey. Sir Felix Pole, chairman, and Lusk, vice-chairman of the A.E.I. Ltd., as well as several directors and officials of the British Thomson-Houston Co., were present, also Mr. Philip Lang, former managing director of the British Westinghouse Co.
It is with great regret that news reaches us of the death of Herbert Thomas Walker at his home at South Orange, New Jersey, on January 26. Born in London seventy-four years ago, Walker was for a time in the office of Lloyd Wise & Co., patent agents, of Lincoln's Inn Fields. He went to the United States in the early 'eighties and was connected with the Scientific American as a draughtsman for forty years. His hobby was compiling the history of railways and their locomotives, both British and American. From time to time LM published articles written and illustrated by Mr. Walker, notably those on the Bodmer locomotives, the last of which appeared in our February issue. A collection of 200 of his drawings will be found in the Rosenwald Industrial Museum, to be opened in connection with the Chicago Exposition of 1933.
Death on 28 February 1931 at Acton, of John Armtrong,
Former district locomotive superintendent of the Great Western Ry, at Paddington. He was seventy-nine years of age and retired in 1916, after over fifty years' service. Armstrong was in charge of the Royal trains in three reigns, and superintended the funeral trains of Queen Victoria and King Edward.

Warren, M.I.Mech.E. The centenary of the death of William Syrnington occurs on 22 March, and the council proposes on that day to deposit a chaplet on his memorial at St. Botolph's, Aldgate.
Buenos Aires Great Southern Ry. 4-2-2 Engines No. 101 to
Very few "singles" were then at work, it will perhaps be of interest again to refer to the engines illustrated on page 386 of Vol. 36. The principal dimensions as quoted on the official diagram are appended ;- These engines are known as Class 5, and were numbered 191 to 195 when first built; when the whole of the locomotive stock was renumbered in 1912, the numbers were al tered to 101 to 105.
Old Stockton and Darlington Ry. locomotives.
Re Beckerlegge's letter in the January issue regarding old Stockton and Darlington Ry. locomotives. Nos. 81 and 82 were purchased from the Edinburgh & Glasgow Ry. in 1854, the former engine withdrawn from traffic in 1867 and the latter in 1882. The Seaton Delaval Col1iery No. 4 was purchased from the North British Ry. about 1864, and was of a much lighter construction than No. 81 Millar and 82 Hawthorn, and when delivered at the col1iery it bore the original number plate of the N.B. Ry. on the boiler, the Colliery people cut off part of the plate bearing the word "North" and left the number and name thus; "4 British." The engine was sent to Messrs. Stephensons in 1867 for rebuilding, and I would emphatically state that it was an entirelv different engine from the Stockton & Darlington No. 81 Millar. No. 159 York, afterwards No. 1159, and in July 1904 altered to No. 1674, built by Gilkes & Co. (No. 125), February 1862, rebuilt in 1878, and cut up at Darlington in 1905 with over 1,000,000 miles to her credit; this cannot very well be the Clio owned by the Seaham Harbour Dock Co. The Clio was originally No. 125 North Eastern Ry. and one of E. Fletcher's No. 120 class coal engines erected at Hartlepool in March 1875 under the supervision of the Thomas James. The boiler, cylinders, and wheels were obtained from Gateshead Works. No. 125 was sold to the Seaham Harbour Dock Co. in April 1911, and a few years ago she was reboilered with a second-hand boiler obtained from the railway company, and at the same time received the rather more commodious cab belonging to the locomotive Ajax, which was originally a Blyth & Tyne locomotive and ran on the N.E. Ry, as No. 1308 and latterly No. 1719. The name plate Ajax has now been removed and the Clio has her original name plate. The varying numbers on the boiler mountings are accounted for by the fact of the engine No. 125 receiving transfer boiler during the last overhauls previous to being sold out of service.
Counter-balancing of British locomotives. F.W.
Re letter which appeared in January issue, p. 35, Ernest F. Smith stated that Stroudley used balanced crank-axles, although the fact that he had done so had never been mentioned in print. For my own part, the point in question is certainly new to me; moreover, no reference to the matter occurs in Stroudley's well-known (Inst. CE.'s) paper on the locomotives of the L.B. and S.C Ry., in which Stroudley went fully into the method employed by him for counter-balancing the revolving and reciprocating masses of his Brighton-built engines.
Of those engines, the 0-4-2 "Gladstones" would I think be more likely to have had balanced inside cranks' than the other classes (if at all), yet the sectional drawings of these express engines do not show that they were fitted with such cranks.
Which, then, of Stroudley's locomotives had the 9-in. rear extensions to the crank hoops about which Smith wrote? Were they any of his few engines on the Highland line, or were they some of his L.B. and S.C Ry. engines? Perhaps he will be kind enough to send full particulars. For it is decidedly strange that all mention of so notable and unusual feature (which it would have been in those days) should have been omitted by Stroudley from a paper in which he described his locomotive practice in detail, including the customary rules for balancing the motion parts by means of weights in the rims of the wheels, ·and not otherwise.
Locomotive chimneys and smoke deflection. P.
One of the chief reasons why the steam persisted in "hugging" the boiler top of such engines as the King Arthurs of the Southern Ry, was, I understand, owing to their comparatively low exhaust pressure when running at speed with early cut-off. In fact, they were too efficient for comfort, as far as clear look-out was concerned. When accelerating, or mounting a bank. with consequent higher exhaust pressure, there was no such trouble. The same remarks apply to compound engines with their low exhaust pressure, and it would be interesting, therefore, to know whether the picture of L. & N.E. Ry. No. 10,000 appearing on page 62 was taken at a part of the line which is level or on an up-grade.
I believe that a high-pressure steam "screen" issuing vertically from the back half periphery of the funnel was tried on the "King Arthurs" before the adoption of the German sheet steel "side screens," but that it was found that this expedient actually made things worse! There was another method employed in Germany before WW1 on the Atlantic four-cylinder compounds of the Prussian lines, which consisted in placing an upwardly sloping steel "apron" from the front of the funnel to the back, i.e., starting at the front base of the funnel, and ending at the back rim. This, I believe, was fairly successful, but, of course, required a reasonably high funnel. Regarding the "machines à bec" of the P.L.M., these were, of course, introduced with a view to reducing head wind resistance, and although certain designs of "becs" did probably also act as smoke deflectors, they were not primarily designed for that purpose.
In conclusion, he paid tribute to the designer of the Southern Ry. "King Arthurs" and "Lord Nelsons" in having evolved a form of "side sheets" which in no way detract from the fine appearance of these magnificent machines. "Side sheets" are a necessary evil which, if applied without due artistic thought, might very easily be a source of great disfigurement.
Model S.E. Ry. Locomotive. G.S. Willoughby
Re. G. Geo. Woodcock's letter in February Issue re our model S.E. Ry. locomotive, firstly, let me state quite definitely that it is not a model of one of Cudworth's "Mail" engines. These engines had driving wheels of 7 ft. dia.; 4 ft. 6 in. leading wheels, and 3 ft. 9 in. trailing wheels, also a long firebox with longitudinal midfeather. Our model is of a much smaller engine, and has a scale of 6 ft. dia. drivers and 4 ft. leading and trailing wheels, also an ordinary deep firebox between the driving and trailing axles. The outside main frames are also a different shape, at the front and rear axleboxes, from those of Cudworth. In fact, it has few of the characteristics of Cudworth's singles, but practically all of J.C. Craven's, of the L.B. & S.C Ry.
As stated in the February issue, this model originally belonged to Sir David Salarnans prior to 1885, and as this gentleman was a director of the S.E. Ry. it seems to be hardly likely that he would have such a large model built without some definite prototype. We went to a great deal of trouble during the reconstruction of this engine to discover a possible origin, and the conclusion we came to was this : It is well known that Cudworth and Craven were very friendly and used to copy each other in some of their engines. and also to loan them occasionally; is it not therefore likely that an engine such ,,~ the model represents started its life on the L.B. & S.C Ry. as a tender engine, and was in its later days either lent or sold to the S.E. Ry. and altered by them in small details such as cab. bunker. and well tank, and perhaps chimney top. and then used either on a branch line or for a directors' saloon engine? There have been many such transactions in locomotive history of which no record has been preserved. . The link motion details and many others, such as axle-boxes, frames, safety valve casing, buffers, etc., etc., are absolutely "Craven." I may add that the number plates on the sides of the cab are the original ones and bear the inscription: "No. 1, South Eastern Railway." The cab anrl bunker are also original, but have been reconditioned. I may state that I have never before seen such an appalling collection of scrap as this engine was when we came to pull it to pieces; nothing was properly fitted or in line; not a single original nut, bolt, stud, or pin remains, and all other parts have been either reconstructed or renewed. [KPJ: Sir David "Salamans" has been assumed to be one or other of Sir David Salomons in which case it is surprising that the comments on workmanship were not refuted: the more probable Sir David had died in 1925]
Of all railways, the history of the S.E. Ry. seems to be the most obscure from the locomotive standpoint, but would make most interesting reading if it could be compiled. In conclusion, if Mr. Woodcock would like a photograph of the model, I would be very pleased to give him one through your office.
Mechanical stokers in Europe. D.R. Carling.
Ini Februiary LM it is stated that Poland is thought to be the first country in Europe to use a mechanical stoker, but I believe that a stoker, of the same type as that mentioned, was fitted to one of the "Pacific" type engines, class 10bis of the Belgian National Ry., as long as five years ago. This was done following a decision to that effect made at the International Railway Congress meeting in London in 1925.
This information is from an article on "Mechanical Stokers for Locomotives" in the paper Baldwin Locomotives for January 1928.
I do not know the result of this experiment or if the stoker is still in use. The new Belgian locomotives seem to be hand-fired.
The origin of the balanced locomotive. F.W. Brewer
At the end of his interesting article in your February number, on Bodmer's 2-4-0 goods tank engines, Mr. Herbert T. Walker stated .that a description would be found in Sekon's Evolution of the Steam Locomotive. From this, it might be thought that these 2-4-OTs were among those dealt with by Sekon. Such was not the case, however.
The first Bodmer engines to which Sekon referred were four with 4 ft. 6 in. six-coupled wheels, and 18 in. by 24 in. cylinders. These engines, the names of the makers of which were not given, were supplied to the Manchester and Sheffield Ry. in 1845. They were stated to have been "powerful goods locomotives" (an expression similar to that quoted in Mr. Walker's article), weighing 24 tons, and capable of hauling a gross load of over 1,000 tons. Such an achievement would, however, be a very improbable one on the part of a 24-ton engine.
Sekon next cited an odd Bodmer locomotive on the Manchester and Sheffield line. This was said to have been constructed (seemingly in 1844) by Sharp Bros. & Co. It had 14 in. by 20 in. cylinders, and 5 ft. driving wheels; type, whether single or coupled, was not recorded. Next came the S.E. and L.B. and S.C. Bodmer "single-wheel" engines, and after these Sekon mentioned another odd example, in regard to which, for the first time, the position of the cylinders (in case outside the frames) was given, similar information in the case of the other "Bodrners" having been ignored. It is well known that the South Eastern & Brighton Ry, engines had inside cylinders, and the inference is, in the absence of any statement to the contrary. that the "Sekon" M. & S. Ry, engines also had inside cylinders.
The solitary outside cylinder "Bodmer," quoted by Sekon, had 22 in. by 24 in. cylinders, 7-ft. driving wheels, and 110-lb. steam pressure. Nothing was said as to the type of the engine, the builder, or the railway on which it worked, or the date when the engine was put into service. All of the foregoing locomotives had Bodmer's patent double pistons the stated stroke being equally divided in each cylinder the two pistons moving in opposite directions. The M. & S. Ry. 2-4-0Ts dealt with by Mr. Walker had 6 ft. 2 in. coupled wheels and 17 in. by 30 in. outside cylinders; hence, they did not correspond with any of the Bodrner engines as chronicled by Sekon in his work, but were additional examples of Bodmer's designs. Assumedly, all of Sekon's examples were tender engines.
North British Ry. tank engines. C. Hamilton Ellis.
With reference to the. very interesting account of Mr. W. Hurst's tank engines for the North British Ry. in the February issue, the article runs: "They were rebuilt later . . . . and were scrapped in the early 'eighties by Mr. Wheatley." This should read "Mr. Drumrnond," as the latter succeeded the former in 1875. Outclassed by Wheatley's 0-6-0 saddle-tank engines of the early 'seventies, they were finally taken out of service on the introduction of the relatively modern "Drumrnond" tank engines previous to 1881, by which time all four of the standard "Drummond" tank engine types had appeared.
The late E.L. Ahrons, by the way, gives the numbers of these engines as 96-99 and 103-108. The new Nos. 96 and 97 were "Drumrnond" "Terrier" tank engines Arbroath and Bonninqton ; 98 and 99 were the small 4-4-0T engines Aberfoyle and Roxburgh; 103-5, Montrose, Roslin, and Penicuik; while 106~8 were three more "Terriers," Tayport, Leuchars, and St. Andrews.
Les Chemins de Fer Coloniaux de l'Afrique, Lionel Wiener, Paris:
Librairie Dunod, 574 pages. 30 maps. Paper covers.
Conditions influencing the establishment and operation of railways in the Colonies embody many varying factors; the political and administrative conditions, physical features of the districts served, general difficulties encountered, such as labour, construction of works, etc., are seldom similar. A study of the railway systems in the African Colonies is bound to be of interest, and the author's work will be appreciated by railway experts and all who study questions of Colonial expansion. The book, which is in the French language, deals with the railways in the British, French, Belgian, and Portuguese Colonies in Africa, and gives the general characteristics of the various systems and reasons for their construction. Mention is made of the types of locomotives used. Quite a number of maps show the existing lines and extensions proposed, and tables of statis- tics of the lines open for traffic, with, in some cases, traffic returns, add to its value for reference purposes. Covering such an immense field, the facts and data have had to be arranged as concisely as possible, and a certain amount of condensing of the information has been inevitable, but the author is to be complimented on the general arrangement of the work.

The present volume deals only with the elasticity and strength of materials, and is designed primarily to assist students taking the B.Sc. (Engineering) degree at London, or the examination for the Associate Membership of the Inst. of C.E., and other similar examinations, but it is also intended as an introduction to the mass of information now available to the engineer. It is divided into two parts. Part 1 deals with elastic strains and stresses and Part 2 with the properties of materials as determined by experiment.

Institution of Locomotive Engineers: Paper on "Improvements
in water pick-up gear", by Mr H. Chambers. 113.
Paper No. 277. After narrating the early adoption of such to enable locomotives to undertake long runs by Mr. John Ramsbottorn, the locomotive engineer of the L. & N.W. Ry., Chambers proceeded to describe in detail the most approved arrangements used on the LMS Ry., devoting particular attention to the many improvements which had been incorporated in the latest forms used on that line.
A verv interesting account was given of the results obtained in experiments made with a special tender constructed at Derby Shops, in which an observation chamber was provided. Careful notes made in actual working had enabled great improvements to be made in the provision of anti-splash devices to enable the maximum amount of water to be taken whilst an engine is passing over the trough with a minimum amount of waste.
Provision of a deflector plate about 1 ft. 4 in. in front of the scoop has enabled the following records to be made: (1) Average increase of water picked up at all speeds was about 200 gallons, representing about 17% improvement; (2) The amount of water picked up is constant for all speeds between the minimum or critical speed and 60 m.p.h., but as speed increases the amount of water splash causing waste rapidly increases; (3) The reduction of water lost by splash is constant for all speeds and was about 400 gallons, representing a reduction of about 50% at a speed of 40 m.p.h. The water splash as a percentage of the total water taken from trough, for the two cases is as follows
|Min. speed 20 m.p.h||60 m.p.h.|
The author proceeded to show the huge amount saved by the total number of engines equipped with this pick-up gear on the L.M. & S. Ry., some 4,000 locomotives, assuming each locomotive fitted made an average of two pick-ups per day, not an excessive figure considering that on some through runs there were as many as nine pick-ups per turn. Daily there was a saving of pumping 7,000,000 gallons of water.
Valve gear of L. & N.E. Ry. high-pressure locomotive.

Gresley before Institution of Mechanical Engineers.The special valve gear employed on high-pressure locomotive No. 10000: drawings of extremely ingenious motion, which not only constitutes a most interesting detail of a highly original engine, but also appears to offer the simplest method hitherto devised to allow of independent cut-off control in compound locomotives. Since the railway locomotive has to furnish a power output that varies almost momentarily, the problem of designing a two-stage expansion system suited to it is far more difficult than with marine or stationary engines, in which the load in n:ost cases remains fairly constant over lengthy penods. In order that the power developed in the high and low pressure elements shall be reasonably well balanced the degree of expansion in the low-pressure cylinder must be a fraction of that prevailing in the high-pressure cylinder, and in practice this is best brought about by an alteration of relative cut-off of the high-pressure and low-pressure valves.

Continued from page 91. Four tender engines, previously in use on the Cambrian Rys., were also allotted to the B. & M. Ry. Of these, two were of the 0-6-0 type, one, which had been No. 20 Vulcan on the Cambrian Rys., but was renumbered 3 on the B. & M. Ry., having been built by Sharp, Stewart & Co. in 1862 (WN. 1342), and was precisely similar to the Caerleon and Caerphilly. The other, No. 16 De Winton on the Cambrian Rys. and renumbered 6 by the B. & M. Ry., was built by Manning, Wardle & Co. in 1862 (WN. 41), (Fig. 6), and, though of a generally similar type, differed both in dimensions and other characteristics which followed the practice of the builders. The wheels were 4 ft. 6 in. dia. on a wheelbase of 14 ft. 3 in., and the cylinders were 16 in. by 22 in. The tender was on six wheels of 3 ft. 6 in. dia. with a wheelbase of 10 ft. 6 in., and had a tank capacity of 1,350 gallons. This engine was named after Mr. J. Parry de Winton, the chairman until 1865 of the B. & M. Ry. and a local banker.
The other two were of the 0-4-2 type, and on the Cambrian Rys. had been No. 4, Wynnstay (Fig. 7), and No. 6, Glansevern. They were built by Sharp, Stewart & Co. in 1859 (WN 1146 and 1148), and were renumbered by the B. & M. Ry. 12 and 11 respectively.
The coupled wheels were 5 ft. and the trailing 3 ft. diameter, the wheelbase being 7 ft. 2 in. from leading to driving, and 6 ft. 8½ in. from driving to trailing. The cylinders were 15½ in. by 22 in. The boiler, with an inside diameter of 3 ft. 8 in., had 145 tubes 2 in. by 10 ft.2 in., which contributed 800 sq. ft. of heating surface to a total of 873 sq. ft., the grate area being 13 sq. ft. The tender was on four 3 ft. 6 in. wheels and carried 1,200 gallons of water and 3 tons of coal.
Three small saddle tanks of Manning, Wardle & Co.'s build, and all precisely alike, complete the list of engines acquired from Messrs. Savin and Ward. The origin of these is a little obscure, but one or more of them had previously been in the service of the Cambrian Rys. The engine, which on the latter line had been No. 15 Hereford, and was built in 1862 (WN 49), was, on transfer to the B. & M., renumbered and renamed 16, Lady Cornelia (Fig. 8). Another, named Usk, also built in 1862 (WN 58), is thought to have been No. 22 on the Cambrian Rys., but was renumbered 15 by the B. & M. Ry. The original service in which the third was engaged cannot be traced, nor its date of construction, but it is understood to have been employed in making the Cefn branch, and was numbered 17 and named Blanche by the B. & M. Ry. These engines had 3 ft: 1 in. wheels, and inside cylinders12 in. by 17 in., the wheelbase being: leading to driving 5 ft. 5 in., driving to trailing 5 ft. 4 in. The boiler, 2 ft. 9 in. by 7 ft. 9 in., contained seventy-eight 2-in. tubes. The heating surface was: tubes 330 sq. ft., firebox 40 sq. ft., total 370 sq. ft.; grate area 6.75 sq. ft. The saddle tank carried 450 gallons of water, and the engine weighed 16 tons 11 cwt. in working order, 5½ tons being on each of the leading and trailing axles, and 5 tons 11 cwt. on the driving. The Usk, commonly called the Little Usk to distinguish it from the tender engine, No. 9, was sold to Mr. J. Mackay, of Newport, and the Lady Cornelia to the Tuthill Limestone Co. The latter engine was named after Lady Cornelia Henrietta Maria Churchill, eldest daughter of the seventh Duke of Marlborough, who, in May 1868, was married to Sir Ivor Guest, the famous ironmaster of Dowlais and afterwards Lord Wimborne. The twenty-three engines described above formed the stock of the line at the completion of the system in 1868. Six further engines, to meet the development of the traffic, were added by the end of 1872. Although these were, in the main, similar to the Atlas class, in order to increase the adhesive weight and extend their working range, they were provided with larger tanks, and the driving axle was placed 5-in further back, the distance between driving and trailing centres bemg only 4. ft. 9 in. Like their predecessors, they were designed and built by Sharp, Stewart & Co. and delivered in three lots two at a time. No. 24 Cyfarthfa and No. 25 Sir Ivor (WN 2059 and 2087) were built in 1870, No. 26 Samson and No. 27 Hercules (WN 2144 and 2166) in 1871, and No. 28, Rumney (Fig. 9), and No. 29, Taff (WN 2261 and 2260) in 1872. In this class the tanks carried 900 gallons of water, and the bunkers 20 cwt. of coal, the loaded weight being 36 tons 19 cwt., distributed to give 11 tons 1 cwt. on the leading, 12 tons on the driving, and 13 tons 8 cwt. on the trailing. Nos. 28 and 29 were fitted with the Chatelier counter-pressure brake when new. The Cyfarthfa and Sir Ivor were sold to the Cyfarthfa Ironworks, Sir Ivor becoming Cyfarthfa No. 12, and the Samson to the Rhymney Ironworks. The Hercules was involved, as previously stated, in the Talybont accident of December 2, 1878. The Taff was sold to the Consett Iron Co. and became their No. A9. It was rebuilt by A. Barclay & Co. in 1904 and finally sold for scrap in 1924.
In 1877 the B. & M. Ry. purchased from the Neath and Brecon Ry. two engines which that company had to dispose of in consequence of an arrangement it had come to with the Midland Ry. for working a portion of its line. They had been Nos. 7 and 8 on the Neath & Brecon Ry., and were built by the Avonside Engine Co. in 1874 WN. 1013-4), and on the B. & M. Ry. were numbered and named 30 Alt and 31 Tor respectively (Fig. 10). They were saddle tanks of the 0-6-0 type, but differed from the standard engines of the B. & M. Ry. in having outside frames. The wheels were 4 ft. 6 in. diameter on a base of 15 ft. 8 in., and the cylinders were 17 in. by 24 in. The tanks had a water capacity of 990 gallons, and the bunkers held 2 tons of coal. These two engines were only withdrawn from service in 1921, and broken up at Machen the following year, before the line was taken over by the G.W. Ry.
There was no further increase in the number of locomotives during the next thirty years, but, with the exception of the two just referred to, the whole of the engines previously described were disposed of before the end of 1905, and consideration must now be given to the newer series of locomotives which replaced them and which carried on the service until the amalgamation.

On Sunday, March 22, the 11.30 a.m. express from Euston to Glasgow and Edinburgh was derailed at Leighton Buzzard as it was crossing from the down fast to the down slow line, fifty minutes later. Three passengers and the driver, fireman, and one of the restaurant car staff lost their lives. The engine was No. 6114, Coldstream Guardsman, of the "Royal Scot" class. The train consisted of fourteen coaches the first four of which were destroyed. Colonel Mount, chief inspecting officer of railways, has been appointed to enquire into the cause of the accident. The inquest was opened on Tuesday, March 24, and after evidence of identification, was adjourned until April 16.
The passenger service on the Bankfoot Light Ry. (Strathord Junction to Bankfoot), L.M. & S. Ry., was WIthdrawn on April 11 but the branch will still be used for goods and stock traffic.

William Tolley retirement. 143
After forty-eight years' service on the old Midland and L.M. & S. Rys., Mr. William Tolley, of Derby, retired at the end of March. Mr. Tolley was known throughout the Midland Division for his activities in connection with the Locornotive Mutual Improvement classes as instructor. During his railway service Mr. Tolley has graduated from engine cleaner, fireman, and driver, to the rank of locornotive inspector, which he attained in 1904. As a result of the lead set by Mr. Tolley, Locomotive Mutual Improvement classes had been formed at nearly all the locomotive depots on the L.M. & S. Ry.
Mr. Francis L. Lane, O.B.E., chairman of G. H. Sheffield & Co. (Engineers) Ltd. and formerly managing director of the Leeds Forge Co. Ltd., died at
Headingley, Leeds, on March 12. Mr. Lane, who was seventy-four years of age, started his career at the Stratford Works of the Great Eastern Ry, and then joined the staff of Sir A. M. Rendel & Son. He was appointed works manager of the Ashbury Carriage and Iron Co., Manchester, and left in 1895 to become works manager of the Leeds Forge, and later manager, general manager, and managing director. He left in 1919 to become director of Clayton Wagons Ltd., and on the taking over of the Leeds Forge in 1923 by Cammell, Laird & Co. Ltd. he rejoined the Board.

Cyril Hitchcock obituary. 143
We regret to record the death on March 24 of Mr. Cyril Hitchcock until recently a partner In the firm of Robert White and Partners of Westminster, consulting engineers to the South Indian and other railways, who was sixty-five years of age within a day or so. Mr. Hitchcock obtained his training in the locomotive department of the Great Western Ry., and then spent some years on the North Western State Ry, of India. He was district locomotive superintendent in charge at Rawal Pindi for 5¾ years. On returning to this country he joined the staff of Sir A. M. Rendel & Son, and took a leading part in the preparation of the first standard locomotive designs for the Indian Rys, He. read an important paper on this subiect before the Institution of Mechanical Engineers in 1910. On joining .Mr. Robert White, Hitchcock attended to the consulting work connected with the Great Indian Peninsula Ry. and was an authority on the mechanical engineering problems of that system. He helped in much of the early history of the locomotives of that railway, as narrated in our serial articles in Vols. XXXIV. and XXXV.
Modification. of British goods train equipment. F.W.
See article in March Issue where J.G.B. Sams refers to the. disadvantages of very long goods trains. In this connection it is generally assumed that "equivalent" trams consisting of four-wheeled wagons must necessarily be longer than those composed of high-capacity vehicles. As far back as 1904, however, It was shown that taking two trains, each carrying a paying load of 420 tons, one train being made up of twenty-one 70-ton wagons and the other. of fourteen 30-ton double-bogie vehicles, the latter tram .exceeded the former in length by 62 ft., and in gross weight by 4 tons. The tare weight in each case was the same, viz., 30 per cent. of the gross weight. Mr. Sams was of course, dealing with long trains. as separate units. Neverthelcss. when it comes to a question of valuable siding accommodation, it will be seen that ten trains of these 30-ton bogie wagons would mean, by contrast with the same number of trains of 20-ton four-wheelers, the occupation of an extra space of 620 ft., and, incidentally, an increase in weight of 40 tons.
"Grosvenor" L.B. & S.C. Ry. Malcolm M.
See Maskelyne's account of the Stroudley singles, particularly Grosvenor. When Grosvenor came out she was fitted with a steam brake, also a hand gear on the engine footplate on the right-hand side to apply the brake to the engine wheels; also a speed indicator was fitted on Mr. Stroudley's own specification and design-a leather belt from the crank-shaft drove a small fan, which maintained a column of water a certain height in a graded glass tube according to the speed at which the engine was running. Regarding the suggestion that Grosvenor was slower and more slippery in "lifting away," she had 6 ft. 9 in. wheels and the others 6 ft. 6 in., and also perhaps the boiler pressure was just a little too high for such a big single wheel on a greasy rail; in any case, most big-wheel engines get away in a more dignified way than those small-wheeled classes, and they are not able to be thrashed. Take the 7-ft. Stirling bogies of the old G. & S.W. Ry. as an example' they started with a slow measured beat, and began only to get a move on after being drawn into the expansion.
Mr. Stroudley's engines were about fifty years in advance of the times. He gave his design to the North British Ry., for Mr. Dugald Drummond built two "Stephensons" tor the North British Co. at Cowlais; one was named Berwick, the other Glasgow; and he also built a few "Terriers." . The Stroudley master hand can be seen on the North British, Caledonian, and L. & S.W. Rys, No. 123, the famous "Caley" 4-2-2 was a developed Grosvenor or Stephenson, so when we picture those beautiful Brighton engines of over fifty years ago they are far in advance of any engines, except perhaps those of the late Mr. S.W. Johnson, of the Midland Ry., or Mr. James Stirling, of the S.E. Ry.
Grosvenor had front and back dampers, duplicate water gauges, and a modern firedoor opening with lever and sector. I think the late Michael Reynolds words are worth repeating:- .
"This locomotive was constructed with extreme care, and the workmanship is as nearly perfect as possible."
Mr. Reynolds, as many know, was on Mr. Stroudley's staff for many years, and wrote many technical works.
"Stroudley's Singles," L.B. & S.C. Ry. Frederick
In Mr. Maskelyne's very interesting article he cannot understand why Grosvenor should have been slower in starting than her sister engines, Stephenson and Abergavenny. It is probable that Stroudley "lapped up" or put larger valves in the Grosvenor than in other "singles," possibly for coal-saving purposes. He was keen on saving coal. I remember that Mr. Stroudley, when building the celebrated "D" class tanks, put larger slide valves in Keymer, and the result was she was very sluggish in starting compared with the rest of her class. He afterwards altered her and made her to have the same slide valves as her sister. .

Harry Willmott died on 11 April 1931 aged 79 at Guildford. Joined Great Eastern Railway in 1865; rising to goods manager for the London district. In 1895 he was appointed general manager of the Lancashire, Derbyshire & East Coast Railway. After its absorption by the Great Central he became chairman of the Stratford-on-Avon & Midland Junction Railway. From 1911 he became chairman of the Isle of Wight Central Railway, general manager of the Sheffield District Railway and chairman of the Edge Hill Light Railway.
Brecon & Merthyr Tydfil Junction Ry.
Continued from page 97. The first of the original locomotive stock to be replaced were Nos. 11 and 17, which numbers were allotted to two new 0-6-0 saddle tanks built by Sharp, Stewart & Co. in 1881 (WN 2974-5). Like their predecessors from this firm they had 4 ft. 7 in. wheels and cylinders 17 in. by 24 in., but were of a more modern type with the dome in the centre of the boiler and the trailing wheels behind the firebox. Prior to the arrival of the 2-4-0 tank engines described later, they were regularly used on the main line passenger trains between Brecon and Newport. Both engines worked three through trips a day, the Brecon engine being in Newport for three nights a week and the Newport three in Brecon. In 1889 No. 11 was renumbered 18, and both engines passed to the G.W. Ry., No. 17 then becoming 2190 and No. 18 2191. Fig. 11 shows No. 18 in its original state but renumbered, and Fig. 12 as modified.
A few years later twelve more 0-6-0 saddle tanks, of a new type, were purchased for replacements. Six came from R. Stephenson & Co. in 1884, numbered 6, 7, (WN 2447-8), and 8, 5, 15, 16 (WN 2497-2500), and the other six from J. Fowler and Co. in 1885, these being numbered 1, 2 (WN 4995-6), and 3, 4, 13, 14 (WN 5054-7). They were sturdier built engines than the preceding, and had outside frames with wheels only 4 ft. 2 in. diameter, the cylinders being 17 in. by 24 in., as in the former engines. Nos. 1-8 and 13-16 were renumbered by the G.W. Ry. 2177-88 respectively. These engines were the first on the B. & M. Ry. to receive number plates. In outward appearance they were almost identical with Nos. 30 and 31 (page 127 ante), but an illustration of No. 3 will be found in Vol. 8 (1903) of THE LOCOMOTIVE MAGAZINE, page 322.
For the main line passenger service a class of 2-4-0 side tanks was introduced, six of which were built by R. Stephenson & Co. Of these, Nos. 9 and 10 (WN. 2656-7) came in 1888, os. 11 and 12 (WN. 2658-9) in 1889, No. 25 (WN. 2878) in 1898, and No. 21 (WN 3121) 111 1904. No. 11 is illustrated by Fig. 13. They had outside bearings for the leading wheels and inside for the coupled, and bore a considerable resemblance to the passenger tank engines of the G.W. Ry. at that period, in fact, one of the latter was borrowed by the B. & M. Ry. and worked for some few months experimentally between Newport and Brecon before the type was decided upon. The coupled wheels were 5 ft. 1 in. and the leading 3 ft. 7 in. diameter, the cylinders being 16 in. by 24 in. They worked very successfully for many years and appeared to have little difficulty in keeping time between Talybont and Torpantau, even with loads of ten or eleven coaches. No. 21 was withdrawn in 1921 but the other five were handed over to the G.W. Ry., by which they were renumbered, Nos. 9-12 becoming 1402, 1412, 1460, and 1452 respectively, and No. 25: 1458. For many years No. 12 worked the 14.05 through train from Brecon to Newport, returning on the 18.25 out of Newport, reaching its destination at 21.55.
Two mineral tank engines came from the Vulcan Foundry in 1894, and were numbered 23 and 24, the latter being shortly after renumbered 26 (WN 1405-6). They were saddle tanks of the 0-6-2 type, the driving wheels being 4 ft. 7½in. diameter and the trailing 3 ft. 6 in. The latter had radial axles and the total wheelbase was 19 ft. 4 in. The cylinders were 17 in. by 24 in. ; the boiler, with a heating surface of 1,170ft2. and grate area of 14.5ft2, carried a pressure of 150 psi, and the tanks held 1,100 gallons of water. Nos. 23 and 26 were used to work the Royal train from Talyllyn to Merthyr, when King Edward, then Prince of Wales, opened the Talgarth sanatorium on 27 June 1896. Two similar engines came from the same firm in 1905 and were numbered 19 and 20 (WN 2040-1). These latter were renumbered by the GWR 1674 and 1677, whilst Nos. 23 and 26 became 1692 and 1883 respectively. Fig. 14 shows engine No. 23.
In two engines which were obtained from Kitson & Co. in 1896 a return was made to the 0-6-0 type of saddle tank with outside frames, but the wheel diameter, 4 ft. 7½ in., and the cylinders 17 in. by 24 in., were the same as in the Vulcan Foundry engines, and the tanks carried 1,100 gallons of water. The boilers, however, had a heating surface of 1,110 ft2 a grate area of 15.25 ft2, and a pressure of 160 psi, the highest used on the B. & M. Ry. up to that time. The wheelbase was 15 ft. 8 in. They were numbered 22 and 24 (WN 3667-8), and by the GWR were renumbered 2169 and 2170. Three almost precisely similar engines, and having similar dimensions, were built by .Nasmyth, Wilson & Co. in 1900 and numbered 27, 28, and 29 (WN 584-6). These last became GWR Nos. 2171-3. Engine No. 28 is shown by Fig. 15. The total of thirty-one locomotives which had apparently sufficed for thirty years to deal with the traffic of the B. & M. Ry. was at last beginning to prove inadequate, and with the opening up of new collieries and a general improvement in the trade of South Wales additional power became a necessity. Owing to financial difficulties which had all along hampered the B. & M. Ry., little money was available for the purchase of new locomotives, and four second-hand ones were accordingly obtained which had previously been in the service of the G.W. Ry. (To be concluded)

Threc more B17 (Sandringham) class had been completed at North Road Works, Darlington: Nos. 2829 Haworth Castle, 2830 Thoresby Park, and 2831 Serlby Hall. Armstrong, Whitworth & Co. had completed further 2-6-0 K3 class engines, Nos. 1106, 1108, 1117, and 1118. These engines had been running fish, goods, and parcels trains in the York-Newcastle links, and at least three of them went through to London on April 25 on Cup-Tie Final excursions. The 4-6-4 electric locomotive, No. 13, had been running trial trips between Shildon and Newport:. this was usual every six months or so, to see that the machine is in good order. No. 1619, three-cylinder compound, was scrapped in April, making class B19 vacant. One of the new three-cylinder 2-6-2 V1 tank engines, No. 2911, was working in the London district.

Locomotive speed recorders. Calator
Might I be allowed again to bring up a question which has often been propounded in your columns without, as far as I have seen, ever receiving a satisfactory reply? Why is not the fitting of some form of speed-recording speedometer on the locomotives in Great Britain made compulsory? Several types (of which I need only mention the Hasler) are manufactured at home, and surely their use would ensure the observance of speed restrictions whose necessity has been fully proved by the latest two lamentable accidents which have occurred to express trains within the last six months. Moreover, in the case of non-observance, the record would thus provide that material for estimating accurately the speed at which a train was travelling at the fatal moment, which otherwise depends on the widely varying estimates of members of the train staffs, which must provide so much confusion in the subsequent enquiries. The answer generally given is that the fitting of such instruments would entail unwarranted expense. But how far is this argument justified in the long run? The cost caused to the company concerned by such accidents as those at Carlisle and Leighton Buzzard must be enormous: the indirect costs of insurance, compensation, etc., are by no means inconsiderable.
In the competitive motor-car a speedometer is fitted as a matter of course, and it may be presumed that the initial cost of the instruments has greatly decreased in consequence, while maintenance is an item almost negligible. The fitting of recording speedometers is compulsory, or, if not that, universal, on Continental railways, while even certain of our Dominions and Colonies do not disdain to use them, despite their increased cost, which these administrations are usually less able to afford than our own.
I was interested to see, in The Times Trade and Engineering Supplement, that the question has again been mooted, and that the "Flaman" type of instrument is favoured. If this measure is to be adopted, would it not be of great gain to the British manufacturers to carry out a thorough trial with British instruments, which have proved their worth by being used abroad (even in France, the home of the Flaman instrument) ?
A living contradiction of the conservative prejudices of British superintending engineers against the use of steel in the construction of coaches may be seen in the admirable photographs of the Leighton Buzzard accident which have appeared in the Press: may it be hoped that an awakening in this matter and on the subject of speedometers may take place?
Standard Gauge 2-6-2 Tank Engines. F.W. Brewer.
I am inclined to think that the L.M. & S. Ry. had a few of Mr. H. A. Hoy's L. & Y. inside-cylinder 2-6-2 side tank engines left at the time of amalgamation. These engines, of which there were originally twenty (all having now been scrapped), were constructed at Horwich in 1903, and they were, therefore, contemporaneous with No. 3100 (formerly No. 99) of the same type, but having outside cylinders, on the G.W. Ry, Thus the recent Derby-built 2-6-2T's are new to the L.M. & S. Ry, as regards the position of the cylinders, while the engines with the same wheel plan which were turned out at Doncaster in 1930 are not only novel to the L. & N.E. Ry., but are also an innovation in a general sense, being the first 2-6-2 tank locomotives on the British standard gauge to have three cylinders instead of only two.
Contractors' Locomotives. A.G. Dunbar.
References to what are termed "old" locomotives are very frequent these days of mass-production in scrapping (which, if it appears an Irishism, please overlook), so that I venture to put forward a word on behalf of the type of locomotive known as "contractors'" or "private owners'" and spoken of generally in Scotland as "pugs." Several of these standard gauge machines of the 0-4-0 variety must have attained a fairly respectable age in their somewhat monotonous duties. I saw one recently, a Barclay dated in the 'seventies, while another was a Dubs 1879, the latter being at the Dalmarnock Gas Department of Glasgow Corporation. Several of the earlier Black Hawthorn engines are in the possession of Shanks & MacEwen, the contractors, and I remember seeing near Stirling a venerable old engine called Manor Powis No. 2, which appeared to have been built about the Stone Age. A field of investigation seems to lie open here for any enthusiasts to trace the oldest engine now running in these islands, which I believe will be found amongst representatives of these engines.
L.B. and S.C. Ry. Locomotives. Ernest F. Smith.
In reply to Mr. F. W. Brewer's letter on page 106 of March issue I should like to say that the engmes to which I referred as having balanced crank-axles were those built by Mr. Stroudley for the Brighton line. As a youth I spent some time engine-cleaning on that line at Battersea shed, and I have a very strong visual recollection of the difference between the cranks of Stroudley's engines and those by R.J. Billinton, the latter of which had hoops of uniform thickness, while Stroudley's had the rear extensions referred to in my former letter.
Further than this, however, as twenty-five years is a long time to remember details, it was my habit, when a cleaner, to make sketches of parts of the engines, and among these sketches which I still have, is one of the driving-axle of the "D'" class of 0-4-2 tanks. A copy of this sketch is enclosed herewith, and in this will be clearly seen the feature to which I refer.
CRANKS OF MR. STROUDLEY'S ENGINES. L.B. & S.C. RY.
It will be noticed that the square holes which I mentioned as being
filled with lead are not shown in the drawing. On this point I have only
memory to rely upon. There is, however, in my mind a very persistent image,
which refuses to be doubted, of these holes.
They were not, if I recollect aright, holes right through the hoop, but were recesses in the outside faces, so as to leave a thin web between the bottom of the holes and the inside face of the hoop. They were not readily seen on a casual examination, as on one side they were against the axle-box, while on the other they were covered by the eccentrics.
Apart from whether the extra weight of the lead was there or not, however, the fact remains that the hoops were shaped as shown, and if it was not for balancing purposes it would be very interesting to' know the reason for it.
The only class of Stroudley engines which I cannot speak of from personal knowledge is the "Big Goods," or earlier class of 0-6-0 tender engines, as none of these were stationed at Battersea during my time. In the description of these engines which appeared in Engineering, February 9, 1872, they are shown with crank hoops of uniform shape, but whether they kept these to the last or not I do not know.
In Michael Reynolds' Locomotive Engine Driving, published in 1878, drawings of Stroudley's single-wheeler Grosvenor are given, in which the crank-webs are shown without hoops. Whether this is correct or not, she certainly had hoops, and these of the shape shown in my drawing, in latter years.
The "rooters" or "Terriers" were the only ones of Stroudley's engines which I knew of as having no hoops to their cranks; probably this was on account of their small size, which made the provision of a crank-axle strong enough for its work quite an easy matter without having to use hoops.
In thinking over the matter, as a cleaner, it occurred to me that the reason for this shape of hoop might be that the engines were originally designed without hoops, as the "rooters" certainly were, and that when hoops were afterwards fitted, these were balanced by making them of this form. If, however, the moments of the hoops are calculated, I believe it will be found that there is a preponderance on the side opposite to the crank-pin.
I had never seen Mr. Stroudley's paper on locomotives until after my previous letter was written, but when I was able to consult that work I was surprised to find that no reference was made by the author to balancing the cranks. Further, as remarked on by Mr. Brewer, the diagrams appended to the paper shows hoops of uniform shape, whereas, however' correct this may have been for the "Gladstones" at the time the paper was written, they certainly had the shape of hoop shown in my drawing in later days.
Stroudley Singles, L.B. & S.C. Ry. J. H. McDowell
See Maskelync's "Notcs" on the above on page 99, especially his remarks about the Grosvenor, In a book (published 1877) entitled Locomotive engine driving," by Michael Reynolds, the Grosvenor was selected for description as being representative of best locomotive practice of the period, and very full details, dimensions, specifications, and cross sections are given. From these details the number of tubes, length and diameter, agree closely with those given by Ahrons and The Engineer for 1875, and are, no doubt, the original ones, for as Mr. Reynolds was at that time locomotive inspector, L.B. and S.C. Ry., he could speak with authority. This book, the first written for locomotive men, ran through nine editions in fifteen years, and so the Grosvenor became world famous in locomotive circles. In addition to the Newark Brake Trials she took part (in charge of Mr. Reynolds) in Captain Galton's classical experiments on brake hlocks and brake friction on the L.B. & S.C. Ry. in 1879-80. the results of which are to be found in the Proc. Inst. Mech. Engineers of that date. They were also published in Mr. Reynolds' book on Continuous Railway Brakes (1882) and in a privately printed pamphlet by the Westinghouse Brake Co.
In addition to the above, the Grosvenor had some speed records to her credit which are probably still unequalled on the L.B. & S.C. Ry. This interesting engine should never have left this country, and if she is still running in Italy, perhaps some interested and benevolent millionaire, like Mr. Ford, might be induced to bring her back and place her in the Railway Museum at York, along with the Gladstone, an honour of which she is well worthy.
The Grosvenor L.B. & S.C. Ry. F.W. Brewer.
With reference to Mr. Malcolm M. Niven's letter in your April issue, I think it may be said, without any exaggeration, that the very high standard of workmanship displayed in the Grosvenorwas also present in all of Mr. Stroudley's engines. Mr. Stroudley was a locomotive designer of quite exceptional ability, and when he died in 1889, at the early age of fifty-six, we were left to wonder what line his ultimate practice would have taken had he lived to carry on
The slipping and slow starting of the Grosvenor are not explained by the difference of 3 in. in the diameter of the driving wheels of this engine, as compared with those of the Stephenson. With equal steam pressure, the Grosvenor had a lower tractive effort, and half a ton greater adhesion weight, than had the Stephenson, so that, logically, the former should have been really less liable to slip than the latter, under otherwise identical condition.
The more probable solution is to be found in the letter of Fredk. Wm. HolIiday, for the reason that, if the slide-valves of the Grosvenor had a larger lap than usual (for experimental purposes ?) it might be that the driver, in his endeavour to get away, would put on more steam than the adhesion would bear, and so cause the driving wheels to slip. As soon as the engine was linked up, the power would fall off, and the engine would become more or less "stuffy." Yet, if the case actually was as surmised by Mr. Holliday, it is curious that the longer valves (such as those said to have been temporarilyand unsuccessfullytried in the "D" class tank engine, Keymer), were not replaced by more suitable ones.
At all events, in my opinion, neither the size of the driving wheels nor the particular boiler pressure employed had anything to do with the delinquencies of the celebrated Grosvenor, in so far as slipping and sheer sluggishness were concerned. The engine had a tractive force which was 395 lb. less than that of the Stephenson, but, on the other hand, it had, according to the published figures, an adhesion weight of 14 tons, as against the 13½ tons of the latter.
The Vulcan Locomotive Works, 1830-1930. London:
Locomotive Publishing Co. Ltd. 122 pp.
This is a detailed description of the up-to-date plant of the locomotive works of the Vulcan Foundry Ltd. at Newton-le-Willows, as well as a record of varied designs of locomotives built there. Established in 1830, the firm celebrated its centenary last year, and historical accounts of its achievements during that period form practically a chronicle of locomotive development. Numerous illustrations and a series of collotype plates show the varied types of locomotives constructed during that period. A special chapter is devoted to the Indian standard locomotives supplied during recent years, and another section deals with the latest methods of shipment of locomotives for railway overseas. To those interested in British locomotive history the book will be found to contain much interesting data, with illustrations which have not hitherto been published. The work represents a considerable amount of research in the archives of the firm.

Five of the series of 2-6-0 mixed traffic engines, under construction at Crewe, had appeared, Nos. 13225-9. These, together with the next five, had been allocated for service on the Western division as above. Work was also well in hand at Crewe with a series of No. 2 class 4-4-0 passenger engines of LM.S. standard design, the first of which, No. 636, was expected out shortly. Several new 0-6-0 standard shunting tanks ex-Horwich had arrived in the London district, numbered 16750-4.
No. 5968 Claughton class 4-6-0, was running with the cab and boiler mountings altered to suit the Northern loading gauge. This engine, apparently, had replaced No. 5942, of the same type, which was referred to in the May LOCOMOTIVE as being re-fitted with a standard boiler. No. 5968 is attached to the Western division.
No. 8182, a 0-6-0 coal engine of Webb design. has been purchased by the Shropshire and Montgomeryshire Light Ry. Co., this being the second engine of that type to be taken over.
Further tank engines recently fitted for motor service include 2-4-2 type No. 6605 and 0-6-2 type No. 7729. No. 9014 had been converted from G class to G1 class (superheater) and provided with a standard Belpaire boiler. It was also fitted with the vacuum brake.

No. 14010 L.M.S., the last single in regular service, was back again at Perth (South shed) and running to Dundee daily. The engine had been to St. Rollox works for a thorough overhaul and had a full set of new tyres; the number now appears on the cab side. A few of the former 766 class of the Caledonian Ry. had recently lost their eight-wheeled tenders and been fitted with six-wheelers, and running on short workings round Stirling, to Dundee, Callander, Edinburgh, and Glasgow.

A period of financiakl difficulty forced the railway to purchase secondhand locomotives from the GWR: 0-6-0ST Nos. 1693/4 (Swindon WN 1086/-7/1887) were acquired in 1906 and became Nos. 33-4. In 1907 No. 1685 (Swindon WN 1078/1886) was acquired and became No. 32. In 1922 these locomotives reverted to their former GWR numbers. In 1908 a 4-4-0ST was acquired from the Ebbw Vale Steel Co.: this was former GWR No. 1490 (Swindon WN 1702.1898) which beca,e No. 35: it was sold to the Cramlington Coal Co. in 1916 becoming their No. 5: see also 36, 233.. The appointment of Thomas Dunbar as locomotive superintendent marked a return to new purchases of 0-6-2T from Robert Stephenson & Co.:Nos. 36-9: WN 3379-82/1909; and 40-3 WN 3577-80/1914. A former LSWR 4-4-2T No. 0376 (Beyer Peacock WN 1840/1879) was acquired in 1914 and given No. 44. It became GWR No. 1391. Further 0-6-2T, but with larger coupled wheels were Nos. 45-7 WN 3645-7/1915 and No.s 48-50 WN 3798-3800/1920. These became GWR No. 1372-5; 1668; 1670. Finally a purchase was made of Ministry of Munitions 0-6-0T which became No. 35. Tyhis was Kerr Stuart WN 3070/1917; ROD 605 and beacme GWR No. 2166.

[Fire clay]. 213
In building furnaces, brick arches for locomotives, etc., the clay used should be from the same source as the bricks used if long life is to be secured; further, the smallest amount of clay possible should be used at the joints. A firebrick arch built with bricks wide apart and thick joints of clay invariably collapses after very short service.
L. & N.E. Ry .worshops. 213
As a result of the reorganisation of the repair shops of the L. & N.E. Ry, following the grouping of the railways, the time taken for a complete overhaul and general repairs, which formerly took sixty to seventy days for each engine, is now reduced to twenty- three days per engine. The number of locomotives waiting for, or under, repair had been reduced from 11,5 per cent. to 7 per cent. Locomotive construction was concentrated at the Doncaster and Darlington Works, with an output of 100 locomotives per year, and these shops also undertook repairs, but the works at Stratford; Gateshead, Cowlairs, and Inverurie were limited to repairs only. The building of new carriage stock was carried out at York, Doncaster, and Dukinfield, and of wagons at Darlington, Doncaster, and Dukinfield. The capacity of the three works is approximately 500 carriages, and of the two wagon shops 10,000 wagons per annum. Between 1923 and 1930 £500,000 had been spent on machine tools, the largest item of which, £150,000, had been on wheel lathes. Thirty-seven of these had been installed.
G.W. Ry. locomotive "City of Truro.". Wm. E. Briggs
It is with much satisfaction I learn that the famous G. W. Ry. record-breaker, City of Truro, has been spared . the scrap heap and sent for preservation to the York Museum. To all who have been responsible for the preservation of this noted engine are due the thanks and congratulations of locomotive enthusiasts. It is to be hoped that a few more representatives of noted types may yet be similarly treated. In this connection I would like to mention a Precedent of the former L. and N.W. Ry., a Highland Ry, 4-6-0 of Jones' design, as being the pioneers of British 4-6-0s, also a James Stirling 4-4-0 of the 240 class, in original state. To return to the G.W. Ry. City class, I should be much interested to have a few dimensions and particulars of the valve gear, travel, setting, and port dimensions, as obtaining at the time of City of Truro's record run. I say at that time, because I do not know if alterations to the valve gear were ever carried out, such as has been the case with certain engines on some railways.
Steam loconiotiue design. Wm. T. Hoecker. 213-14
On page 16 of your January number it is stated that "American engineers favour the dome" as a location for safety valves. An inspection of the drawings of one hundred different types of locomotives built for North American railways during the past six years reveals that fifty-six of these designs have the safety valves situated on the boiler barrel between the dome and the firebox, in the very place recommended .by the article; forty-one engines have the safety valves located above the front portion of the firebox or combustion chamber, and only three have safety valves mounted on the dome.
The subject of liquid fuel, which is discussed in your March number, prompts me as a resident in a region where oil has been used as locomotive fuel continuously and almost exclusively for nearly thirty years, to offer some comments from a practical standpoint. The variety of fuel used on any portion of any railway depends primarily on the relative cost per unit of work done. On the larger systems in the western half of the United States, which have main lines around 2,000 miles in length, the proximity of oil fields or coal mines usually determines the kind of fuel to be used on any division. The average age of the locomotives in use on American railways to-day is approximately seventeen years, and the working life of an average American 'locomotive may be estimated at thirty years. It is quite conceivable that, during such a period of time, the oil supply in some regions may become depleted to such an extent that coal assumes its former place as the cheaper fuel; or traffic conditions may require the transfer of engines from oil-burning to coal-burning divisions or vice-versa. In such circumstances the possibility of making the necessary alterations in the firebox arrangements with a minimum of expense and delay is a distinct advantage.
Phillipson's charge that the orthodox type of locomotive boiler is unsuitable for burning liquid fuel is perhaps based on the more or less desultory and experimental use of such fuel in Great Britain. It is, nevertheless, a fact that the deep, narrow firebox, similar to that generally used on British locomotives, has been found the most efficient form for oil-burning in Russia, The dogmatic assertion that "burners should be mounted at the back of the firebox," though supported by Russian practice on the small engines used in that country, is contrary to the opinion derived from experience with 7,000 oil-burning locomotives now running in the United States,
The table on page 86 supports the universally admitted theory that "the blast-pipe orifice should be as large as possible," but it does not indicate any inefficiency in steam generation. Any type of locomotive boiler that will evaporate from 12 to 13 lb. of water per pound of oil, in heavy grade working, is certainly doing all that can be expected. The relatively high fuel consumption per 1,000 ton miles indicated in this table is due to the fact that the engine was running over longer and heavier gradients than are encountered on any British main line.
Repeated tests and calculations on various American railways have shown that from 1,100 to 1,300 lb. of oil fuel are required to do the work of 2,000 lb. of coal, the exact amount depending largely on the relative calorific values of the two fuels. On the Atchison, Topeka, and Santa Fe RR., 1,200 lb. of oil are considered equivalent to 2,000 lb. of coal; the Southern Pacific Co. and some other large systems use a ratio of approximately 1,260 lb. of oil to 2,000 lb. of coal in the compilation of comparative reports of fuel consumption. These figures demonstrate indisputably that the American locomotive boiler can be arranged to burn liquid fuel or coal with equal efficiency.
Turning back to your October 1930 number, I find some remarks regarding firebox stays on pages 336-337. Those of your readers who might be interested in the use of steel stays would do well to study the statements made by the Chief of Motive Power of the Canadian National Rys. before the American Railway Association on June 24, 1930. This system has used steel stays since 1920, and breakages to-day are less than half those of several years ago. A considerable number of their boilers carry 275 lb. pressure and they are fitted entirely with hollow steel stays. No flexible stays are used.
The "U.S. Association of Master Mechanics," mentioned on page 16 of your January number, should be correctly designated at the "American Railway Association-Division V-Mechanical."
L. & N.E. Ry. Hiqh-pressure locomotive. Oscar Brunler. 214
Re article about L. & N.E. Ry. high-pressure locomotive which appeared in April number, it is stated on page 113 that "the degree of expansion in the low-pressure cylinder must be a fraction of that prevailing in the high-pressure cylinder. ... " (if the power developed in the high and low-pressure cylinders is to be well balanced).
This statement is hardly correct, for while it is true that an exactly equal power output is rarely obtained in practice in the conditions of ordinary working, this is the ideal to be sought, and the above statement is therefore quite meaningless to anyone conversant with the elements of steam engine design.
In fact, the whole object of the variable control to the two sets of valve gear is that the work done in each pair of cylinders may be equitably apportioned between them, and as this is clearly implied by the remainder of the article, it would seem that the word "fraction" may have been used in place of some other expression which would have conveyed the meaning desired.
New "Super-Pacifies," Northern Ry. of France. C.M. Keiller. 214
These "Super-Pacifies" of the Nord undoubtedly do work that is of the very first class, .but it is difficult to understand why it is necessary "to credit them with a theoretical tractive effort that seems to be quite fictitious, and it would be interesting to learn how these figures are obtained. Before discussing the tractive efforts I would say that I rather fancy that the boiler and· receiver pressures which you give as absolute are really gauge pressures, and assurning that they are the tractive effort as a simple, taking. the M.E.P. as being the full available pressure, is only 50,120 lb., which is 650 lb. less than that given; also the compound tractive effort, again taking the full available pressure is 37,910 lb. against the 37,830 lb. given. If we take the M.E.P. available as being the usual 85% of the full pressures, the tractive efforts are: simple 42,600 lb., compound 30,440 lb., against the 50,770 lb. and 37,830 lb. quoted.
It seems that these inflated values must be the result of some definite policy, as the same thing occurred in the description of the earlier locomotives of this design which appeared in THE LOCOMOTIVE in 1924, only here they were Just that much lower than would be indicated by the boiler and receiver presures, being 1 kg. per sq. cm. and 0.5 kg. per sq. cm. less respectively than is now given.
Castlederg and Victoria Bridge Tramway. J. H. McDowell. 214-15
The writer was much interested in the account of the Castlederg and Victoria Bridge Tramway in the April number, as he knew this line in its earlier years, and its locomotive superintendent, Mr. Bracegirdle. For some time after it was opened the trains were worked by hand brakes, but on one occasion several wagons broke away near the top of the bank and ran down about two miles to Victoria Bridge, where they became derailed at the curve entering the station yard, and piled up in a heap just clear of the G.N. Ry. (I) line to Londonderry. After this, the stock was fitted with the Westinghouse automatic brake, and it is interesting to see that it is still in use. This little line, therefore, has the distinction of being the first and only line in Ireland to adopt this brake. The Kitson engines, Nos. 1 and 2, were fitted with a very inconvenient form of combined lever brake and regulator handle, so that the continuous brake was a great boon to the driver. After No. 3 came, in 1891, Mr. Bracegirdle, with local assistance, took in hand the re-building of Nos. 1 and 2 in the same form as No. 3. This was in 1896 or 1897, when the writer saw them partly completed. He has not been there since 1905 so has not seen Nos. 4 and 5. Mr. Bracegirdle came from the old Belfast and Northern Counties Ry., which was the first line in Ireland to adopt an automatic continuous brake, as far back as 1882, when some of the stock was fitted with the automatic vacuum brake, then just being perfected, and the writer remembers this brake in regular work in the mid 'eighties, when many other lines were using the simple vacuum.
Mention of the Ballymena and Larne engine No. 105 also recalls memories of this little line near the writer's early home. It was projected and largely carried through by the late Mr. James Chaine, M.P. for S. Antrim, a director of the old B. & N.C. Ry., and who largely built up Larne Harbour as a cross-channel port. The writer's father was then connected with Mr. Chaine, and kept the accounts of the construction of the line, and he himself recalls riding on the footplate of No. 6 in Ballymena goods yard. There were originally six engines, Nos. 1, 2, 4, and 5 being 2-4-0T and Nos. 3 and 6 0-6-0T. All were fitted with Smith's plain vacuum brake, with the bottle-shaped vertical ejector beside the smokebox. This was afterwards changed to automatic vacuum after the B. & N.C. Ry. took over the line about 1887 and 1888. The B. & L. Ry. was locally known as the "rat's pad" (path) in allusion to its 3-ft. gauge compared with the standard 5 ft. 3 in. Irish gauge and when taken over the highest number on the B. & N.C. Ry. was 50, but there were three narrow-gauge (3-ft.) engines on the Cushendall line numbered 60-62, so the B. & L. Ry, engines followed these for a short time, later being re-numbered over 100. About 1902-3 Nos. 104-5 were often to be seen at Larne Harbour ready to take the Ballymena train on arrival of the Stranraer steamer. Enclosed is a photograph of 104 at that period. The engines looked clean and smart little models, and drivers were very proud of them. This engine 105 has, therefore, been at work for about fifty years, and it is hoped that it will still be capable of some years' work on the C. & V.B. line.
A new poppet valve gear. V. Holmes. 215
I was interested to see that you gave such a full report of the meeting of the Institution of Locomotive Engineers, at which I read a paper, but I would like to point out a mistake in the description of my gear. Your report states: "Reversal is secured by sliding the cams and these oscillating levers along a rifled seat on the cam shaft." This is not the case, there is no sliding movement of either cams or levers. Reversal is effected by turning a member (called the fulcrum carrier), which carries the oscillating levers through an angle of 900 from the point of minimum opening to steam. The exhaust cam is reversed by means of the longitudinal movement of a helically splined sleeve between the exhaust cam and the camshaft; this movement of the sleeve is also effected by the turning of the fulcrum carrier. Also the oscillating bellcrank is not "mounted on the cam shaft" but on the fulcrum carrier; it is, however, oscillated by a rotary cam on the cam shaft. I enclose a diagram which makes the principle of the admission side clear. For backwards running the parts would be in positions of looking-glass symmetry to those shown in the figures. .
"Stroudley's Singles." A.G. Williamson. 215-16
Re Maskelyne's article on the Stroudley singles in the March issue and the subsequent letters thereon: was surprised to see Maskelyne depicted Grosuenor as having driving wheels with twenty-four spokes. On looking up the history I see that it seems to be shown there, too. Maskelyne says that she retained her wrought-iron driving wheels to the end, but my memory of them is that they contained Stroudley's standard number of twenty-two. They are shown thus in the illustration in The Engineer when the engine first came out. I do not wish to suggest that Maskelyne's drawing is necessarily wrong. It may be that at some time of her career she temporarily carried a pair of driving wheels out of one of Craven's singles, as he did at times build a wheel with twenty-four spokes, whereas as far as I know Stroudley never did.
Again, I cannot think that .the alleged sluggishness of starting of Grosvenor compared with the other singles could have been due to the very slight increased diameter of the wheels. The explanation as pointed out by Holliday as being due to valves is more likely to be correct, though not quite as he surmises. Grosvenor had an outside lap of 7/8 in., lead of 1/8 in., and, I believe, no inside lap. But according to the History, Stephenson had 1/16in. lead and an inside lap of 1/8 in. Such an engine should be a better starter, small lead being required, and the inside lap giving a slightly higher M.E.P. at slow speeds. 'But, of course, if the valves were proportioned .thus, the engines would be likely to be "tied up" at high' speed. And.I was never 'fortunate enough to time one of Stroudley's engines' at really high speed. Whenever The speed 'went up towards the sixties over would go the regulator. With regard to the tubes of Grosvenor, it is likely, I think, that she was rebuilt with 1½ in. tubes, as there are several obvious misprints in the History with regard to' tube' numbers and dimensions.
Coming back to driving wheels again, Stroudley certainly built some' with crescent-shaped balance, weights. Edward Blount was shown thus at the Paris Exhibition of 1889, and she had been built early in the year, and 'they were probably cast. steel.

Federated Malay States Rys. locomotives. 270
In the description of the above in last issue (page 217) the statement that these are the largest non-articulated locomotives in the world operating on the metre gauge is obviously incorrect, as, for instance, the "Mikado' engines built by Robert Stephenson & Co. Ltd. in 1927 for the Kenya & Uganda Rys. are bigger, with 17 tons on the axle, and a total weight of 155.9 tons (see Locomotive Mag., August 15, 1\927 p. 241). We should have said it was the most powerful non-articulated passenger locomotive in the world. There is a "Pacific" type engine on the metre gauge section of the Argentine State Rys. about 4 tons heavier, but the Federated Malay States Rys. locomotive is more powerful.

Efforts were being made in the United States to secure an automatic coupler arrangement to connect up all the different hose pipes, electric circuits, etc., of passenger trains when coupling between engines and cars is effected by impact. The A.R.A. are investigating the subject with a view to the adoption of a standard device, and trials and experiments had been in progress for some time past at Purdue University. For two years the B. & O. RR. had been running a passenger. train in regular service equipped with a device known as the "O.B.

Locomotive progress on the West Australian Rys.; abridgement
of a paper read by J,W,R. Broadfoot before the Perth Division of the Institution
of Locomotive Engineers, 340-4. 8 illustrations
This does not appear to have been published in the Journal of the Institution of Locomotive Engineers in spite of Broadfoot being Chairman of the Western Australian section. The article, less the illustrations, is reproduced .
In' Western Australia three weights of rails are used, viz., 80 lb., 60 lb., and 45 lb. per yard. Ot the 80 lb. there are 139 miles of single track between Fremantle and Northam, but until the bridges are strengthened the maximum weight per axle permitted is limited to that allowed on the 60-lb. rail. The 60-lb. rail, therefore, may, for the present, be considered as the standard, and of this 1,959 miles of track are laid. Of the 45-lb. rail there are 1,820 miles the balance, making up the total of 4,111 miles of main line, being of odd sections, 46½ lb., 50 lb., and 55 lb. The total mileage laid, including sidings, is 4,538 miles.
The maximum axle load permitted on the 6O-lb. track is 12 tons 12 cwt., and on the 45-lb. rail 10 tons per axle, and the weight and conseqently the power of the engines is restricted accordmgly. The rapid development of the agricultural areas made heavy demands on the railways, and during the twelve years from 1919 to 1930 the gross ton mileage hauled by goods and mixed trains increased from 659,892,615 to 1,093,070,481, an increase of 65.6 per cent., and until the end of 1924 the locomotive stock had not been increased.
Up to 1924 the adoption of superheaters had been limited, but the increasing demand for power led to a marked increase in this direction, and to-day all the principal classes of locomotives are fitted. The results have been entirely satisfactory, as all such engines are now hauling generally a 10 per cent. greater load than formerly, and at the same time showing a reduction in cost of working of 12½ per cent.
In 1922 to 1923 it was evident that the locomotive stock would be insufficient to cope with traffic demands, and it was realised that engines would have to be imported. Specifications and general plans were prepared and tenders called for a Pacific type engine suitable for express work on the 60-lb. section. This is shown by Fig. 1, and known as class "P." At the same time engines were urgently required for the fast mixed and goods service on the Wongan Hills and Northern line, and a rather bold policy of re-designing and converting twenty obsolete compound engines into simple superheated engines suitable for the 45-lb. rail was developed and adopted. These engines were originally designed for the heavier rails, but by transferring some of the weight carried by the coupled wheels to the leading and trailing bogies it was found possible to keep the weight on the coupled wheels down to the regu- lation limit for the 45-lb. rail. This work was carried out in the Midland Junction works, the first engine finished in 1924 and the last in December 1925. ,
This policy proved to be eminently sound, as the engines have given excellent results, paid for the conversion in four years, and to-day are running at from 4d. to 6d. per mile less than before conversion. They are also greatly in favour with the engine crews owing to improvements made for their comfort.
An important experiment in cylinder lubrication was first tried on these engines. In the past the hydrostatic lubricator delivered oil at four points in each cylinder; to depart from this and provide only one feed to each cylinder steam pipe seemed at the time an extreme step.
The improvement in lubrication and econorny in oil have fully justified the action taken, and one- point cylinder lubrication is now standard practice. These engines are known as class "L," and are shown by Fig. 2.
At the end of 1924 the "P" class Pacific engines were received from Great Britain and issued to traffic. These engines were the first to be fitted with the wide firebox (the grate area being 35 ft2.), and this has proved most successful and economical for use with the native coals, and the results obtained from the engines generally were such that fifteen more of the same type have since been built in the W.A.G.R. workshops. This provided the opportunity of embodying certain improvements in the design, and the locally-built locomotive is proving equal in every respect to the imported.
The importation and building of new engines, the re-designing and improvements effected in others, and the relaying of a number of sections of our 45-lb. track with 60-lb. rails, which extended the range of the heavier and more powerful engines and improved running organisation. has enabled the railway department to write off and scrap a number of obsolete types of engines, with the result that whilst the haulage has increased considerably, the number of locomotives in service at the beginning of this year was less than it was twelve yea rs ago. This is summarised as follows:-
Increase in 12 years
Gross ton miles hauled
Miiles of railways open
Total tractive power of locomotives
Number of locomotives in service, .
The rapidly increasing wheat yield indicated that at the end of 1930
there would be difficulty in hauling the harvest, and provision to meet this
was made by the issue of an authority to build ten Garratt articulated
locomotives, of which type several were already in service on the West Australian
Rys. A new design entirely would have been preferable, but as neither time
nor staff were available the existing design was amended and improved as
far as possible, and construction started in February 1929.
In describing the Garratt engine and its development, mainly on narrow gauge lines, Mr. Broadfoot mentioned that the third design prepared by Messrs. Beyer, Peacock & Co., as far back as 1912, was for the Western Australian Rys. These engines are of the 0-6-2+ 2-6-0 type, and are still in service. A further seven were obtained in 1913, but these were superheated, and until recently were the most powerful locomotives working over 45-lb. rails in Australia. These engines weighed 67.6 tons. In South Africa the development of the Garratt locomotive has been phenomenal. The first large Garratt built subsequent to the War was for the South African Rys. in 1921, with a total weight of 133.75 tons and a tractive effort of 53,703 lb. To-day this is overshadowed completely by a Garratt engine which weighs 214.1 tons, and is the largest in the world working on a 3 ft. 6 in. gauge track. The tractive !' effort at 85% working pres- sure is 89,133 lb. So far as Australia is concerned the heaviest and most powerful Garratt type locomotive is operating on the New Zealand Government Rys., as the engine weighs 145.7 tons, with a maximum axle load of 14.65 tons and a tractive effort at 75/"0 working pressure of 51,800 lb.
The locally-built West Australian Garratt is, owing to the axle load restrictions, smaller and less powerful than the South African or New Zealand engines, the leading dimensions being :-
Cylinders, 13¼ in diameter by 20 in. stroke.
'Coupled wheels, 3 ft. 3 in. diameter.
Rigid wheelbase (each unit), 7 ft. 6 in.
Wheelbase, total, 48 ft. 6 in.
Heating surface-Tubes 701 ft2
Flues 269 ft2
Firebox . 116 ft2
Working pressure, 175 lb. per sq. in.
Tractive effort at 85 % working pressure, 26,784 lb.
Total weight in working order, 74 tons.
Maximum axle load, 10 tons.
Coal capacity, 4 tons.
Water capacity, 2,000 gallons.
The tractive effort is higher than that of any other class of locomotive
on these railways, and is 30% in excess of that of any of the ordinary type
of engine capable of working over the 45-lb. rail section.
The cylinders, valves, and valve gear were redesigned entirely, the firebox lengthened by 12 in., and grate area increased from 22.6 sq. ft. to 27 sq. ft. Many other improvements ascertained by practical experience on these railways were made with the earlier Garratts. Construction was started in February 1929, the first engine was issued on February 22, 1930, and since then one engine per month has been placed in traffic.
Illustrations showing stages in the construction of these engines serve to exemplify and explain the Garratt form of construction and some special features peculiar to the engines themselves. Fig. 3 clearly shows the straightforward and simple form of the boiler. The single plate barrel and straight-sided Belpaire firebox are in striking evidence.
Some interesting points in cylinder design may be noted in Fig 4, which shows a pair of cylinders having barrels and steam chests bored simultaneously. Attention is drawn to the shape of the facing on the end of the steam chest and to the open end of the exhaust passage, which is closed by the steam chest cover. This form of construction eliminates much costly core-work in the foundry and simplifies machining operations. A good idea o£ the engine unit construction may be gained from Fig. 5, which shows the main pivot bearing very clearly. In Fig. 6 the centre or boiler unit is shown slung above the engine units, ready for complete assembly. This, and the preceding figure, serve to show how the three units are brought very near completion while still independent of each other, and the gain in erecting costs and time is obvious. A further stage in building is shown in Fig. 7, the three units being finally brought into place. A view of the completed engine is given in Fig. 8.
No doubt the space between the smokebox and the front tank will excite comment. It is provided to permit the use of the standard smokebox door and allow withdrawal of most of the boiler tubes, with the tank in place.
Economy and effectiveness in cylinder lubrication have been pursued still further in this design. The imported Garratt engines were fitted with an eight-feed mechanical lubricator at each end. These were later displaced by hydrostatic lubricators. To-day these latest Garratt locomotives have only one hydrostatic lubricator of one pint capacity to supply all cylinders. Oil is delivered into the ball joint in each main steam pipe and is then carried by the steam through the steam chests and cylinder barrels to the ball joints in the exhaust pipes, which are very effectively lubricated by this means. Grease lubrication was applied to all crank bearings and has proved most successful.
Service trials have been conducted over various sections with excellent results, the engine steaming freely under the maximum loads. On the suburban section over grades of 1 in 80, loads of 701 tons were hauled without trouble of any kind; and on the hill section over grades of 1 in 45 loads of,320 tons were hauled equally satisfactorily ..
These loads represent increases of 81% and 6% respectively over the tables for the heaviest goods locomotives on the system.
From the foregoing results, particularly those given in the table, it is evident that considerable efforts have been made to improve the haulage capacity of the locomotive stock, but in a progressive State, such as Western Australia, closer attention still must be given in the future to provision of more efficient motive power. Improvement in power is subject to dimensional limits determined by the gauge of rails, loading gauge. weight of rails, curves, and strength of bridges. Curvature of the rails limits the length of rigid wheelbase, and may place a limit on the employment of non-articulated locomotives. That the gauge of rails is not in itself a rigid limitation of power has been amply demonstrated in South Africa, where the development of the 3 ft. 6 in. gauge has proceeded steadily. Similar development in Western Australia is not only possible but probable.
To build articulated locomotives suited to the existing track is from some aspects a more sound economic proposition than to alter the track to permit the employment of more powerful "orthodox" locomotives. Two outline designs were submitted by the author. These represent the maximum eight-wheels coupled engines which can be built to run over the existing 45-lb. and 60-lb. rails. The former has a maximum axle load of 10 tons and the latter 12.6 tons. Despite their great weight, power, and length, such engines could work over the lines on which the present Garratts are operating. On such a section the loads would not be less than 352 tons and 427 tons respectively, while on less steeply graded lines they would haul maximum loads at greater speeds than are at present possible. There is no immediate prospect of building such engines, but the author has no doubt that the progress of the State will necessitate an extensive locomotive development on the lines indicated within a measurable period of years.
We regret to record the death, as the result of a fall from the Kathiawar Mail train, on 16 September, near Anand, forty miles from Ahmedabad, of Henry Arrnitstead, M.B.E., carriage and wagon superintendent of the B.B. & C.I. Ry. (metre gauge section), Ajrner. He was fifty-four years of age and joined the railway in 1920, after having served the North Western Ry. He was responsible for the building of the saloon used by H.R.H. The Prince of Wales during his last visit to India.
On 5 October Mlatthew Stirling, late locomotive superintendent of the Hull & Barnsley Ry., died at his residence in Hull, in his 75th year. He was appointed locomotive superintendent of the Hull & Barnsley Ry. in 1885, and retired on the amalgamation with the North Eastern in 1922. His father was Patrick Stirling, the famous locomotive superintendent of the, G.N. Ry., and his uncle, Jas. Stirling, locomotive superintendent of the G. & S.W. Ry. and later of the South Eastern Ry. M. Stirling served his apprenticeship at Doncaster Works.

Moving a "depot supply warehouse" by the L.M.S. Ry. 360.
Charles Churchill & Co. Ltd., of Leonard Street, London, were faced with the problem of removing approximately 400 tons of material without interrupting the supply of goods to their customers. In the past this company had carried the major portion of their stocks at a warehouse in Salford, near Manchester, from which they supplied various branch warehouses scattered about the country. To provide swifter and more efficient service to their customers they decided to concentrate these bulk stocks, and their head office, in one building in London, and approached the L.M. & S. Ry, Co. with their problem, the immensity of which may be realised when it is stated that this material ran' to over 20,000 different items pigeon- holed in steel racks.
To achieve the end in view it was decided to utilise the period including the August Bank Holiday, and the loading of this immense amount of material was undertaken successfully by the only means available capable of affecting the results desired. 150 four-ton capacity L.M.S. "Containers" were brought into service, and on Friday and Saturday (July 31 and August 1) these "Containers" were loaded not only with goods and racks, but carried also all the necessary records and paraphernalia essential to the continuation of distribution, on arrival.
These were carted from the company's Salford warehouse to a L.M.S. Manchester goods depot, and it required three special trains to convey them to London (St. Pancras). On arrival, the "Containers" were held at St. Pancras so that delivery could be effected when the streets were quiet. Delivery was made by road from St. Pancras on Sunday and Monday to the new premises. By the use of a 6-ton petrol-electric mobile crane, the loaded "containers" were delivered right into the building itself, into positions most convenient for unloading.
The move is remarkable evidence of the triumph of the "Container" methcd of transport and the rapidity and completeness with which the operations were carried out enabled the firm to continue business from their new loca- tion immediately after the holiday period. It should be made clear that Churchill's machinery business established over sixty years ago and in which branch of industry they are equally well known, was not affected by the above-mentioned move, as we understand that they will shortly be effecting a similar concentration of this side of their business in the Birmingham area.
Preservation of L. & N.W. Ry. 2-4-0 Engine "Hardwicke."
Kenneth H. Leech, John Woodgarde, Warnette-Wood, O. S. Nock, H.M.
There are now very few of the famous "Precedent" or "Jumbo" class of L. & N.W. Ry.' locomotives still running, and it is probable that those yet remaining will very soon join what the late Charles Reus-Marten, who wrote so enthusiastically and appreciatively of their work, once called "the grim procession to the scrap-heap." In one of the last articles he wrote before his death, Mr. Reus-Marten put forward an earnest wish for the preservation of one of these "wonderful little engines." In October 1907 he wrote "But when the fatal date does draw near, I should be glad to see one of them preserved as a specimen of what once 'was, i.e., thirty years ago, the best specimen of an 'all-round' machine of its date, combining all the great requisites of speed, haulage power, construction, cheapness, economy; and simplicity.'
This puts concisely our case for the preservationpreferably at York Railway Museum, where there is as yet no L.M.S. locomotive#151;of Hardwicke, undoubtedly the most celebrated of the survivors of the class by reason of her record run on August 22, 1895, from Crewe to Carlisle at an average speed of 67.2 miles per hour.
Hardwicke was built in 1868 by John Ramsbottom, and rebuilt about 1890 by F.W. Webb.
May we venture to ask you to exert all your influence in this matter? There are so very few historic locomotives still in existence that the present opportunity really ought not to be lost.
[Old Belgian locomotives]. F. Gaiser..
Referring to Mr. A. Jacquet's articles on old Belgian locomotives (Locomotive , January. 1929 and August, 1931), I should like to mention that there were at least five more English locomotives for the railways which con- stituted the Grand Central Belge. Before going, however, into the details, it seems advisable to give the exact dates of fusion of the several railway companies, this knowledge being of importance to understand my remarks. The Est Belgewhich was itself the fusion, in 1859, of the Charleroi a Louvain (opened February 12 to August 14, 1855) and the Morialme a Chatelineau (opened June 14, 1855) Railway Companies-united with the Antwerp & Rotterdam Co. (opened June 23, 1854 to May 3, 1855) on January 1, 1864 and with the Entre Sambre et Meuse (opened November '27, 1848, to November 14, 1854) on July 1, 1864: from which latter date the whole concern was styled Grand Central Belge." It was not until August 1, 1867 that the Aix-la-Chapelle a Maestricht-Landen Ry. was merged into the Grand Central Belge system.
The existence of the five English engines is shown by an article on "Explosions of Locomotive Boilers in Belgium," which appeared in The Engineer, January 11, 1889, pp. 29 and 30. According to this article, which was compiled from the reports of a Mr. Vinscotte or Vincotte, two locomotive boilers, made in England for the Sambre et Meuse Ry., exploded the one, made in 1856 at Lodelinsart on October 4, 1864, and the other, dating from 1855, at Antwerp on February 23, 1866 (the year 1866 is not given in The Engineer, but is ascertained from other sources), and it is added that both these boilers, with three others, were handed over to the Grand Central Ry. of Belgium shortly before they exploded, and that, after the second explosion, i.e., in 1866, all were broken up. This latter circumstance accounts for the fact that no trace of these engines can be found in the Urban-album of 1871. On the other hand, they made part of the twenty-four locomotives in possession of the Entre Sambre et Meuse Co. before the amalgamation, and of which only nineteen can be traced in the album, viz., Nos. 7-12, 45-52, 64, 93, and 103-105.
In both cases of explosion the back plate of the firebox casing gave way through the flange connecting it to the semi-cylindrical top, and was bent outward. Unfortunately, no further information as to the type of engine is given in The Engineer, but from the Annuaire special des ch.-d. f. Belges, where a summary table of the locomotives of the G.C.B. as on view on January 1, 1866, is given, it may be deduced that the engines in question were of the mixed traffic or six-wheeled four-coupled type with inside cylinders.
I also wish to state that three out of the nine 4-2-0 long-boiler engines possessed by the Entre Sambre et Meuse Co. were rebuilt as 2-4-0 long-boiler saddle-tank engines with 4 ft. coupled wheels for shunting purposes, and figured in the Urban album as Nos. 103-105.
According to notices drawn from Belgian statistical sources the Antwerp and Rotterdam Ry. possessed at the end of the years 1857, 1858, 1859, 1860, fourteen locomotives. Ten of these survived until at least 1871, becoming Nos. 1-16, 17-19, and 992 in the G.C.B. stock, whereas the four other appear to be identical with the four old L.B. & S.C. Ry. engines received in 1855. These latter engines must have been at least twelve years old when bought by the A.R. Ry., and it is not surprising that they disappeared long before 1871. Three of them were disposed of as early as 1861, for at the end of 1861 the number of engines of the A.R. Ry, had dropped down to eleven.
The world's first public railway, Chas. E. Lee. London: The
The format of this booklet is a new departure in the economical production of short treatises on technical and historical subj ects, invoking the aid of mirneography, or duplicating. The result is quite satisfactory, the nine half- tone illustrations and a map being printed separately on art paper. By this means it wili be possible to produce many works of interest and value to the student which would otherwise be economically impossible. Mr. Lee's treatise of thirty-four pages is an account of the Surrey Iron Ry. and its extension, the Croydon, Merstham and Godstone Ry. Details of the original scheme and an account of the course of the two lines are followed by notes on the bridges, per- manent way, and rolling stock; the traction was done by horses. The railway- was used for mineral traffic only. A chapter on the history and fate of the two railways is followed by an account of the various traces which the writer has found in a series of journeys over the route. Much careful research has been made to collect the in- formation, and the book is a most interesting record, which will be valued by railway historians.
Practical railway operatingby T. Bernard HareModern Transport
As district superintendent of the London & North Eastern Ry. at Middlesbrough, Mr. Hare is well qualified to write on this subject. In reviewing the different aspects of rail- way operation and discussing problems which are likely to arise, he investigates the latest and most efficient methods of working. Working costs have increased, and a competing form of transport has been developed, making the problem of carrying traffic quickly and at a low cost an acute one. To keep traffic moving between its point of origin and des- tination is the general aim in railway working, and the importance of a high standard in such matters as punc- tuality, train load, etc., is emphasised in chapters devoted to the arrangement of train services, both passenger and goods. The working of passenger traffic at different forms of termini and the movement of the trains are illustrated by typical diagrams. This section is followed by chapters on goods shed terminals and marshalling yards. Considerable . space is devoted to methods of passenger and freight train working and freight train services. The writer advocates the use of shunting engines of light type, such as the "Sentinel" pattern, and gives many examples to justify their employment, while the data regarding costs of working will be studied with considerable interest. Mineral traffic for shipment is explained by considering the details of a typical example taken from actual practice. Other chapters deal with the pooling of private wagons, train controls, and statistics. In concluding with a brief review of the ground covered, the writer draws attention to the fact that the value of a comparison of practical examples is vitiated by the relative efficiency or strength of character of the personnel in charge at the moment of consideration, and by the varying degrees in which, under the many forms in use, that of departmentalism on the one hand and of centralisation or decentralisation on the other, vary.

L.M. & S. Southend line improvements. 434
Widening and electrification between Barking and Upminster. The scheme which the L.M. & S. Ry. have in hand for the improvement of their London, Tilbury, and Southend section is being rapidly pushed on with, and it is expected that the main feature of the scheme, the widening and electrification of the line between Barking and Upminster, will be completed by July of next year. This widening involves as well as additional up and down electric lines between Barking and Upminster, the provision of two new stations at Upney and Heathway, the rebuilding of Gale Street, Dagenham, Hornchurch, and Upminster stations, with new and enlarged goods yards at Barking, Hornchurch, and Upminster. When completed it will be possible to run through electric trains between Upminster and the City. The widening between Barking and Upminster, in addition to the new and improved stations referred to, necessitates the rebuilding of a number of bridges, amongst which are the bridges carrying the railway over Rainham Road and Hornchurch Road. In order to carry out these two works with as little interference to the traffic as possible, the L.M. & S. Ry. are arranging to divert the existing running lines on to the new portion of the bridge at each place whilst the old portion is being reconstructed. This work, coupled with the other engineering operations involved, will mean that for some weeks the time taken by trains running between Shoeburyness, Southend, and Fenchurch Street will be somewhat extended. Everything possible will be done to minimise the unavoidable late running.
Chief Locomotive Inspector H. J. Robinson, of the Great
Western Ry. 434
Retiring in January. Born in 1867, he started as a cleaner in 1881, and became a fireman in 1888. In 1894 he was promoted to passenger fireman, and a few years later to third-class engineman, and in 1911 was made an inspector, becoming chief inspector in 1928. He has travelled on many Royal trains and has had charge of various distinguished personages. Recently he was responsible for taking the Prince of Wales to Llanelly for the Agricultural Show. In 1906 he was driver of the first 100-wagon coal train from Banbury to Swindon. He was the first inspector to run the 10-30 a.m. down Cornish Riviera Limited from Paddington to Plymouth in four hours with a 500-ton train; also to take 379 tons unpiloted up the banks between Newton Abbot and Plymouth. Last September, when the timing of the Cheltenham Flyer was cut down by three minutes, making the start to stop journey from Swindon to Paddington sixty-seven minutes, Chief Inspector Robinson rode on the engine on the first three trips, when the journeys were made in 59, 58, and 571. minutes respectively.
