Modern developments of the steam locomotive. 1.
Editorial comment: Not so very long ago it was fashionable to prophesy the early decease of the steam locomotive, and the major and minor prophets differed only as to whether its successor should be operated by electricity or the internal combustion engine. Much of this prattle was of course propaganda inspired by commercial or financial interests, and seconded in the lay press by non-technical. "experts" in search of sensational matter to tickle the fancy of those who believe that novelty must necessarily connote "Progress"
Absurd and exaggerated as were many of the claims put forward for the rivals of the steam locomotive, they may have had some value in fostering the rational and legitimate uses of the newer means of traction, and probably had a stimulating effect on those who, confident in the outstanding merits of the orthodox steam engine, had been content to let it develop merely by increasing size and weight rather than by seeking to enhance its general efficiency.
Whatever may happen in the distant future, it is now safe to affirm that, apart from special circumstances, the steam locomotive remains the most efficient source of locomotive power in the sense of giving the best return for money when everything is taken into consideration; but it is equally clear that this agent is still susceptible to improvement to an extent that becomes ever more apparent as scientific methods of research replace the crudities of rule-of-thumb experience.
The current trend of advance, so marked within the last few years, has mainly followed two distinguishable paths. On the one hand we have unprecedented improvements following strictly orthodox lines, and on the other, the creation of entirely novel systems which frequently represent attempts to introduce in the railway locomotive features known and approved in other fields of steam practice.
While it cannot be denied that many of these latter are fairly promising, it is just as well to restrain our enthusiasm, for many examples show that schemes of great merit in themselves, and highly successful in the spheres for which they were primarily intended, manifest all manner of difficulties and drawbacks when operating in the peculiar conditions of the railway locomotive. There is a strong temptation to believe that any arrangement known to give extraordinary efficiency in stationary engines must consequently prove economical in railway service; and this obsession is most likely to fall upon those whose acquaintance with actual. railway conditions is more or less remote. The problem is to ensure that the (usually) costly construction of the ultra-efficient machines shall be compensated by savings in fuel and possibly maintenance charges, though unfortunately the last generally tend to rise in proportion to the capital outlay. Briefly put, it is an excellent thing to reduce the fuel cost by, say, .one penny per mile, if no extra charge be incurred in so doing, but if this attractive saving be outbalanced by an expenditure of eleven pence on maintenance, or interest on capital, or both, the saving in fuel is but a mirage of economy.
It should never be forgotten that the railway engine is in many respects severely handicapped. Restricted space and axle loading, and imperative requirements for the utmost security in operation, make frequent overhaul and attention more necessary for locomotives than for most other machines; hence all and every ccomplication, never in itself desirable, needs be subject to close scrutiny, before acceptance by the locomotive engineer, in whose mind the principle of dependability must always hold the foremost place.
In the claims put forward by inventors and projectors it is singular how little information is vouchsafed as to cost of manufacture and maintenance. Exact estimates of fuel saving are prominently exhibited, but when the question of price is raised, it is commonly answered by saying that although the first machines are admittedly very expensive, quantity production will reduce all costs to a relatively modest outlay. No doubt there is a modicum of truth in this; but even so, "mass-production" methods, however suitable they may be for such things as cheap motor cars or radio sets, are not likely to be applicable to locomotive engineering, if only for the reason that in the former case the ratio of cost of material to cost of machining is much lower than with heavy locomotives, to say nothing of the far higher standard demanded by the latter in regard to length of life and reliability.
Another point to be noted from the mechanical aspect is that many devices which work well when mounted upon rigid foundations and with ample room for access, develop unforeseen troubles when subjected to severe and continuous vibration or are obliged to occupy congested spaces; and this may be one reason why the steam locomotive of conventional form, with all its rugged simplicity, has so long held its own despite a notorious thermal inefficiency, Our present belief is that the most profitable way of progress lies in the perfecting of existing forms and ameliorations in detail, especially those which help to reduce the cost of repairs, and co- relatively to keep ):he engine in activity. Improvements in methods of lubrication, of bearings, and facility of access to working parts, are for instance items which though they be unspectacular, may in the aggregate make a vast difference to the qualities of a locomotive in its primal duty as an earner of revenue.

Diesel electric locomotives, Southern Railway. 2-3. illustration
The Southern Railway Company had put into service three oil-electric locomotives, designed for shunting duties. The framing and mechanical parts were oonstructedat the company'sworks at Ashford, and all electrical equipment was supplied by the English Electric Co. and installed at Preston Works. In working order, each weighs 55¼ tons and has a maximum tractive force of 30,000 lb. The tank capacities were sufficient to enable the locomotives to remain in service for a week without replenishing, They were stationed at Norwood Junction and leave the shed at about 6.0 a.rn. on Mondays and return about 6.0 a.m. on the following Sunday, the shunting in the Norwood Yard being of a fairly continuous nature. It can be 'seen from the photograph that at one end there is a cab across the full width of the locomotive; ahead of this was the control cubicle. O.V.S. Bulleid acnowledged for information.

New A4 Pacific type locomotives completed at Doncaster were Nos. 4462 Great Snipe (King's Cross), 4463, Sparrow Hawk (Gateshead), and 4464, Bittern. (Heaton Junction). New V2 2-6-2 type engines finished at North Road, Darlington, were Nos. 4793, 4794, 4795 and 4796, allocated ,to the Southern Area. Recent withdrawals included B15 class 4-6-0 Nos. 799 and 797; J23 0-6-0 No. 2518; and J71, 0-6-0, No. 811. In connection with the ManchesterJSheffield/Wath electrification scheme, a contract had been placed by the L.N.E.R. with the Metropolitan-Vickers Company Ltd., for the design, manufacture and erection of electric equipments required for seventy mixed traffic Iocomotives, suitable for the overhead line conductor system, using direct current at 1,500 volts. which was the higher voltage standard system authorised by the Ministry of Transport. These locomotives will be of the four-axle double-bogie type, and it is estimated that the weight will amount to 80 tons each, and that the horse-power will be approximately 1,850. The mechanical portion of the locomotives will be built by the railway in their own works.

Four Vulcan Foundry 4-4-0 of 1896/7 Nos. 55-8 became GSR Nos. 450-3, but only No. 453 survived: it had been rebuilt with a Belpaire boiler in 1915. Two Beyer, Peacock 4-4-0s had been delivered in 1906 and numbered 67-8, but No. 68 was scrapped following an incident in the Irish Civil War. No. 67 became GSR No. 454 (Class D8). DSER Nos 4 and 5 had been supplied by Kitson as 0-6-2T in 1896,, but were rebuilt as 0-6-0 in 1908. They were again rebuilt in 1924 and 1926 with larger Belpaire boilers and became GSR Nos, 448 and 449, the largest 0-6-0 on the GSR. The DSER standard 0-6-0 Nos. 14, 65, 66 and 18 became GSR Nos 443-6 and had been classified as J88 and left unaltered. Beyer peacock supplied two 2-6-0 in 1922 Nos. 15 and 16 which became GSR Nos. 461-2, classified K2. Three of the 2-4-0T built at Grand Canal Street remained: GSR Nos. 423-5, Class G1. The 2-4-2T, also built at Grand Canal Street had been broken into two classes: F2: Nos. 428; 430-3 and F3 Nos. 434-9. No. 428 was rebuilt with a  class T Belpaire boiler. Nos. 434-9 had been rebuilt with Class 101 boilers at Inchicore. Three 4-4-2T, Nos. 52-4 were built by Sharp, Stewart in 1893 mainly to work mail trains between Kingstown Pier and Kingsbridge. Nos. 52 and 54 were rebuilt by the DSER with larger boilers and became GSR Nos. 458/9, classified C3. No. 53 (GSR 460) was reboilered at Inchicore. A class of 4-4-2T consisted of No. 20 built at Grand Canal Street in 1911 and Nos. 34 and 35 from Beyer Peacock in 1924 and differed in having Belpaire boilers. They became GSR 455-7 Class C2. No. 456 was rebuilt with a class 351 round-topped boiler.

London, Midland & Scottish Railway. 11.
At the end of 1937 the latest 2-6-2 passenger tank engine ex Crewe was No.. 195. The rest of the series, numbered up to 209, were now well in hand. Armsrrong, Whitworth and Co. had completed delivery of the order for 227 two-cylinder 4-6-0 mixed traffic engines (class 5), the numbers of which were 5225 to 5451 inclusive (A.W. Nos. 1280-1506). The bulk of these engines were attached to the Western Division, on which they have proved themselves ·a very useful and efficient class. The last of ,the non-superheated 0-8-0s—G class No. 9134—was converted into G1 class (superheater) during December, thus completing a series of conversions which began in 1912. As now running No. 9134 was provided with a standard Belpair e boiler and piston valves in place of the former flat valves. The following engines were now running rebuilt with standard Belpaire boilers — G1 class Nos. 9042, 9277, 9350, 9388; G2 class Nos. 9417, 9443. Prince of Wales class 4-6-0 No. 25749 had left the shops fitted with a round ·top boiler. Only two ex N.S.R. locomotives remained at the end of Deoember — Nos. 1432 and 1434, .both M class tanks (0-4-4). The D class tanks Nos, 1567 and 1570 had been withdrawn for scrapping, whilst the New L tanks Nos. 2270 and 2271 had been sold to the Manchester Colliery Co. At Derby the latest 2-6-2 passenger tank completed was No. 170; 0-4-0 tank No. 1274 had been withdrawn.

Institution of Locomotive Engineers. "Experimental locomotives for the Indian State Railways.,". 21-2.
At the meeting held on 15 December 1937, H.H. Saunders gave details of two experimental 4-6-0 locomotives, built in the early part of 1937 by the Vulcan Foundry Ltd. for the Grealt Indian Peninsula Railway, now part of the Indian State Railway system.
During recent years the Indian Railways had effected considerable improvements in locomotive working and whereas twelve years ago the G.LP. Railway averaged only 52.5 miles a day per engine, the figures had risen in 1935-6 to 72 — an improvement of 37 per cent. To still further improve these results by more intensive use of engine power, has given rise to a demand for locomotives that will require the minimum cgtention in sheds and give greater mileage between stoppings ; a regular 10,000 miles per month in pooled service, with a general overhaul in the region of 200,000 miles being aimed at.
To meet these requirements two locomotives were built by the Vulcan Foundry Limited, to the general specification of the Indian Railway Standards Committee and the Great Indian Peninsula Railway, the design being based on the existing 4-6-2 XB type passenger locomotives, first built for India in 1927. An illustrated description with the leading particulars appeared in our issue of July last, from which it will be gathered that although they are very similar in general.dimensions to the earlier engines, they are definitely experimental in detail, and, in addition differed from each other in a number of important details. Their most interesting features are probably the extensive use of roller bearings, on one engine Timken roller bearing axleboxes being fitted and on the other Skefko roller bearings to the driving crankpin as well as axleboxes. There were therefore considerable differences between the two engines. Apart from this it has generally been arranged that the more experimental features, not hitherto tried out, have been fitted to what might be termed the Timken engine; the Skefko engine being fitted with improvements on existing practice on more conservative lines.
The boilers were identical in both engines and followed normal Indian practice generally, except as regards the fireboxes. These are of all welded steel construction and are fabricated from four plates, the tube plate, the back plate, the throat plate and one plate forming the crown, side plates and combustion chamber; there being one longi- tudinal welded seam at the bottom of this to form the latter. The plates were of special firebox quality acid open hearth steel with a maximum phosphorous and sulphur content of .03 per cent. To increase the strength of the welded joints small half-round bridges ¾ in. by ½ in. by 3½ in. have been used. These were welded on all edges and fixed at right angles to the joint at the water side. Two Nicholson thermic syphons of British manufacture were fi.tted to each firebox, butt welded into the crown and lap welded to flanges pressed in the firebox throat plate. Flue and smoke tubes were beaded over and welded into the tube plate, a copper sleeve being inserted between the tube and plate. Water space and roof stays are of Longstrand steel, except in what may be termed the breaking zones where DL type Flannery flexible stays were fitted.
The ashpans were of the hopper type, which is normal Indian practice, with sloping sides arranged so that all ashes will fall into a central hopper. The hopper is fitted at the bottom with swing doors worked either by hand or steam from the ground enabling the contents to be completely discharged without the delay which has been generally inseparable from the earlier designs. Drenching pipes have been fitted on the right and left hand sides of the ashpan.
As an experimental measure both engines were fitted with Klinger reflex water gauges, with sleeve packed cocks for the steam, water and blow down connections, all in lieu of the standard gauge glasses and columns. In addition to this the Timken engine is also fitted for experimental purposes with Klinger seatless piston type valves for the injectors, ejector, soot blowers, turbo-generator, rocking grate and feed pump, and Klinger sleeve packed cocks for the lubricator, blower and pressure gauge. Klinger valves are of a patent design, and have no seating, the valve consisting of a plunger which moves between two renewable and flexible rings of non-metallic material, leakage being dependent on the fit of the rings on the plunger.
The cylinders were of normal design with Caprotti poppet valve gear, operated by a rotary drive from the main axle through a shaft fitted with Hardy Spicer flexible couplings.
Both engines have linered cylinders. In the Tirnken engine these were of Meehanite iron, grade C heat treated to give a Brinell of 240, and in the Skefko engine are of .5 per cent. low silicon iron. The slide bars of the Timken engine are also of Meehanite iron, but in this case grade A heat treated to give a Brinell of 3\0-330 is used. Although there were considerable differences in the design of the connecting and coupling rods, the rods were interchangeable. This is possible as the crank pins were identical, changing over of the rods, however, is not to be 'recommended as there are small differences in wheel balancing. The rods on the Timken engine were of standard design with bronze floating bushes grease lubricated. As an experimental measure, however, the fixed bushes of the connecting rods have been made of Skefko No. 3 steel heat treated after machining; this steel is similar to that used for ball races.
The rods on the Skefko engine, owing to thc necessity of keeping weight down, are made of 50-55 tons nickel chrome molybdenum steel; they are particularly interesting as the crank pin bearings are fitted with roller bearings. The crank pin is fitted with a self-aligning roller bearing both for the connecting rod and coupling rod; these each consist of a double row of rollers working in a spherical outer race common to both rows.
Grease is used for the lubrication of these bearings, being recommended on account of the protection afforded to the housing seals, and its freedom from leakage as compared with oil. The grease used is a soda soap grease suitable for maximum temperatures of 90 to 100 degrees centigrade, and should not, in normal circumstances, need replenishment between shoppings. Grease nipples are fitted, this has been done as sufficient experience has not been gained to say definitely whether they can be dispensed with or not. It should, however, be explained that the grease nipples fitted to the roller bearings of these engines are different to those used elsewhere on the engines for other qualities of grease. By this method it is hoped to hinder at least, the over industrious Indian Maistris (a not inappropriate name for some at least of the fitters employed in India) who might seek promotion by giving a charge of grease, irrespective of quality, to every grease nipple visible.

4-6-0 express locomotive No. 4016, had been named after the Somerset Light Infantry. The christening ceremony at Paddington on February 18 was performed by General Sir Walter Braithwaite, Colonel of the Regiment. The name plate carries the words, The Somerset Light Infantry (Prince Albert's). New engines completed at Swindon: Nos. 7800 to 7803, of the 4-6-0 Manor class; Nos. 4122 to 4124, 2-6-2 tanks; and No. 7243, 2-8-2 tank. Withdrawals were Nos. 1557 and 1819, 0-6-0 tanks, and No. 4382, 2-6-0 tender engine.
At the annual general meeting on February 23, the Chairman, Lord Horne, announced that in view of the increased cost of steam working, Messrs. Merz and McLellan, of Westminster, had been requested to prepare a scheme for the electrification of the section of line between Taunton and Penzance. It has been suggested that the substitution of electric traction may enable considerable economies to be effected. Any decision which may be arrived at will not be carried into effect during the current year.

Highgate-Edgware & High Barnet Lines. 67
Contract placed for the widening the L.N.E.R. line between East Finchley and Finchley Church End. The widening of this section of line is a preliminary to its electrification for Tube trains from the Northern Tube. This is being extended from Highgate to join the L.N.E.R. line at East Finchley and Tube trains will run between the West End and City and Edgware. At Edgware a "joint station" to serve both the existing Morderi-Edgware Tube trains and also the new services from Highgate over the L.N.E.R. line will be built. It is anticipated that the widening will be completed within the next year.

Delivery from the Baldwm Locomotive Works of six high-speed passenger locomotives of the 4-6-4 type, one of which was streamlined, for use in passenger service between Chicago and La Junta, Colorado, a distance of 992 miles. The tender carried 21,000 gallons of water and 7,000 gallons of fuel oil, and is mounted on two. six-wheel trucks. All the axles are fitted with roller bearings, to reduce frictional resistance. The streamlining of engine No. 3460  was designed to blend anto the contour of the train. It consists of a steel shroud built over the locomotive, with a "bullet nose" at the front end of the boiler. This shroud is so shaped that it does not cover the connecting rods and valve motion nor does it obstruct the view from the cab. It was painted in two shades of blue, while the underportions of the locomotive and tender, including the running gear, were painted black. The striping was in silver leaf, and the other faces of the driving wheel tyres and hubs were painted with aluminium paint, as also the tyres of all the engine and tender truck wheels. The hand rails  were stainless steel, and the hand rail columns, cab handles and certain other fittings chromium plated. The boiler was built of nickel steel plates, and carried a working pressure of 300 psi.

It had two cylinders,520 mm. by 720 mm. driving the third pair of coupled wheels, with piston valves, 300 mm. diam., of the internal admission long-travel type, actuated by Walschaerts valve-gear, or Heusinger gear as it is known in Germany. The coupled wheels were  1,600 mm. diameter. The boiler carried a working pressure of 20 kgs. The heating surface of the tubes and flues was 186.12 m2 firebox, 16.1 m2; and of the superheater, 70 m2 The grate area was 4.05 m2. The sand dome was placed between the feed water and steam domes, and feeds to the front of all the coupled wheels by air operation. The cab was exceptionally roomy and well-ventilated, with comfortable seats, and sliding windows and high side doors. The bogie tender has a coal space of 353 cubic ft., and 'carries 7,000 gallons of water. When full it weighs 74.8 metric tons. The overall length of engine and tender is 78 ft. 9 in., and the maximum height 14 ft. O~ in.

On 23 February the Eastern Division Running Dept. held their annual dinner at the Strand Palace Hotel. D. Sheppy, Divisional Locomotive Running Superintendent, occupied the chair. A brief silence offered tribute to the late Locomotive Running Superintendent, A.D. Jones, who died recently. Following the loyal toast, Sheppy presented an "Emblem of Peace" to the Western Divisional Loco. Running Supt., Moore, and a sword with scabbard to Inspector Turner. W.J. England proposed the toast of the Department and referred to the problems which frequently occur, especially during the holiday times. As Assistant Superintendent of the Operating Department, England is in close touch with the Locomotive Running Department and its present chief, A. Cobb, who responded to the toast. After musical honours. Cobb referred to the activities of both departments and their increasing responsibilities. Some of the recent changes in office were also mentioned including  A.B. McLeod's appointmcnt to the Stores Dept. The revival of cleaning the locomotives was briefly alluded to as being an improvement which is appreciated by the staff as well as the general public. Cobb also referred to Maunsell's retirement and Bulleid succeeding him as Chief Mechanical Engineer. Chrimes called upon Marsh of the C.M.E. 's department to propose the toast of "The Chairman," and Sheppy responded. Talented artistes, including a fine pianist, contributed to this most enjoyable evening.

The S. & D. Rly. and its extensions were originally single line, but double line has existed between Midford and Templecombe (Upper) station since the early 1890s, as also between Blandford and Corfe Mullen J unction since the early 1900s; the portion of Midland line run over in entering Bath and that from Broadstone Junction to Bournemouth West on the L. & S.W.R. Rly. being also double. In recent years, the line between Corfe Mullen and Wimborne has been closed and the rails removed except a short piece used as a siding at the Code Mullen end. The crossing loops and other features connected with the locomotive service are given in the diagram reproduced on page 20 ante, passenger stations being shown in full capitals.
The single line sections are controlled on the electric tablet system, and the locomotives are all fitted with a tablet-exchanger of the pattern invented by the then Resident Locomotive Supt., Whitaker, and known by his name, by means of which tablets may be exchanged at speeds upwards of 60 m.p.h. Due, however to the necessity of banking all heavy freight trains over part of the Bath-Midford sectiori a special procedure is there adopted in conjunction with the tablet system; the banking engine at the rear carries a train staff, whilst the train engine carries the usual tablet. The train staff can only be taken out for the particular purpose of the banking, and no second tablet or staff can be got out either at Bath J unction Box or Midford until both the tablet and the train staff have been put back, the former may be returned into one or other of the instruments indifferently, but the staff can only be returned into the Bath Junction instrument. Thus the banking engine can return to its starting place at one end of the section and replace the staff, whilst the train engine proceeds and the tablet is put into the instrument at the other (Midford) end, thus freeing the line. The staff also serves to unlock certain sidings at the Bath end of the section, whilst the tablet unlocks the sidings on the single line SIde of Midford station.
The principal works were always at Highbridge where—until the taking over of the stock by the L.M.S.—all classes of locomotive and carriage and wagon repairs were carried out, up to the "rebuilding" of locomotives with new boilers' the boilers, however (except for certain special seconstructions, mostly of small locomotives made at Highbridge in the 1880-90s) being obtained from Derby. There are running-sheds at Highbridge, Bath, Radstock, Templecombe, Bournemouth West and Wells, whilst there is a turntable and water service at Evercreech Junct. There are additional water-stations at Chilcompton, Shepton Mallet, Sturminster Newton, Blandford and Glastonbury, also a limited supply at Burnham. Until recent years there were sheds at Wimborne and Bridgwater, but these are now closed and the shed and turntable at Wimborne removed since 1932; the turntable and water-service still remain in use at Bridgwater however. A view of the yard and surroundings of the relatively small shed at Radstock, noteworthy as the home of "banking" engines for many years appears in the illustration below.
In handling the main line passenger trains, and particularly the freight trains, on the Bath-Evercrecch Junction section, very heavy pulling is required there being ruling gradients of 1 in 50 in each direction in the 3¾ miles between Bath Junction and Midtord made more difficult of operation by single-line tunnels—one over a mile in length—whilst m reaching the much greater altitude in the 15¾ miles between Radstock and Evercreech Junction, the gradient can be considered as 1 in 50 to 1 in 75 almost half the way in each direction. In the early "Joint" railway days, loads—particularly passenger—were not heavy, nevertheless the locomotives supplied in the 1880s and 1890s seem at first sight considerably under-powered for their work, but as such heavy freight trains as there were then were banked on the worst gradients, in practice they were apparently adequate. With the coming of heavy "North to South-west" seaside traffic and the continued development of the collieries in the Radstock district, as also the important Mendip stone traffic from the various quarries, plus a very considerable increase in agricultural produce raised for markets outside its area of origin, the engines of that period had a struggle to cope with their duties. The writer has vivid recollections of the straits to which the enginemen were put to "get the train over the top" in the mid-1900s. The special banking between Bath Junction and Midford has already been referred to; it should be added that banking is also resorted to as required from Radstock.
Another unusual operating practice takes place at Ternplecornbe where owing to the station being onthe L. & S.W. Ry.line at a higher level than the S. & D. J. Rly. trains have a steep bank to climb. South-bound trains run, without stopping, up the loop-which is a double line-into the L. & S.W. Railway station (on a line adjacent to the up platform), and on leaving therefrom to continue the journey another engine, usually a tank engine belonging to Templecombe shed, is attached at the rear. This engine then draws the train backwards down the loop until the whole train and leading engine having cleared Templecombe No. 2 junction, the tank engine is uncoupled and the train proceeds southwards on to the single Iine section to Henstridge and beyond. Northbound trains run through from the single line until clear beyond No. 2 junction, at which place an engine is attached at the rear and draws the train (the train-engine giving assistance) up the loop into the station; being uncoupled there, the train is then ready to start away in due course without stopping at No. 2 junction. An interesting tablet-exchanger development is connected to No. 2 junction box; it is a "receiver," and its most convenient position for the service is in the six-foot way. It is so made that on receiving the impact from the tablet it subsides into a horizontal position at rail-level, thus avoiding fouling of the necessary loading-gauge and clearance; it is provided with means whereby the signalman can bring it to a vertical position from his box, but its action on receiving a tablet is entirely automatic.
At Wells there is an unusual complication of lines with the G.W.R—mentioned previously—where not only does the S. & D. Rly. form a short portion of the G.W. Rly. through line, but a certain number of S. & D. joint sidings cross the G.W.R. on the level. At Highbridge, where the S. & D. line crosses the G.W.R., the level crossing is an extraordinary "blind" one, from or of S. & D. Jt. trains proceeding across the G.W.R. lines from east to west. Midford station is another peculiarity in that although it is at the termination of a single line section, the station itself has only one platform, being situated actually in the single-line section with the double line commencing at the other end of the station.
The Locomotive Superintendent from 1862 to 1868 was R. Andrews, he being followed by F.G. Slesser until 1873; whilst from 1862 to 1864 J. Cleminson, who came from the Hatcham Ironworks and afterwards became connected with South American railways in respect to rolling-stock designs and patents, was assistant locomotive supt. B.S. Fisher was the locomotive superintendent at the time the line became a "Joint" one, having come from the Taff Vale Railway to succeed Slesser about 1874, whilst W. H. French who came from the Midland Railway at Leicester was locomotive superintendent from the time of Fisher's death in 1883 down to 1889, being in November of that year unfortunately killed at Highbridge by being crushed between the buffers of two wagons. During the latter part of French's superintendency, F.M. French, who had been on the Midland Ry. and on the Grand Trunk Ry. of Canada was asst. loco. supt. W. H. French's successor as resident locomotive supt. was . A. Whitaker, who came from the Midland Railway, having been latterly district loco. supt. at Leeds, and whose tablet-exchanging apparatus introduced on the line some years later, and in 1904-6 installed on the Midland & Gt. Northem Joint Rly., was of great advantage in single-line working. Whitaker was succeeded in 1911 by M. F. Ryan, who came from Derby and went to the L. & S.W. Rly. in 1913 and later became chief mechanical engineer, and is now general manager of the Buenos Aires and Pacific Rly., he being followed in 1913 by R. C. Archbutt, from the Midland Rly.Since the locomotive working and maintenance has been entirely taken over by the L.M.S., the old S. & D. Joint area is included with the Bristol district under the charge of A. H. Whitaker, son of the Whitaker previously mentioned.Illustrations: 19-24 class 0-6-0 on freight train on Blandford to Bailey Gate section in early 1890s (T.F. Budden);

Latest 2-6-2 passenger tank ex Crewe was No. 203, this being the fourth of a series of ten, Of the preceding series, Nos. 185-189 had been allocated to the Northern Division, and Nos, 190-98 to the Central Division. A new series of 4-6-0 mixed traffic engines  would be be put in hand at Crewe. Engines recently repaired at Crewe with standard Belpaire boilers included the following: 4-4-0 superheated Precursor No. 25300 Hydra: 4-6-0 Prince of Wales class :No. 25694; 0-6-0 18-inch goods. No.. 8529 and 0-8-0 G1 class Nos. 9003, 9357 and 9387.

New construction at Derby comprised the last ten of an order for 2-6-2 passenger tank engines (class 3) Nos. 173-184. The 10.00 St. Pancras to Manchester express, together with its corresponding return train at  16.25 from Manchester (Central) had been named The Peak Express from the fact that the train passes between Derby and Manchester through the Peak District of Derbyshire, the highest point attained being nearly 1000 Ieet above sea level at Peak Forest Summit. The 10.00 from Manchester (Central) to St. Pancras, and corresponding return train from St. Pancras at 16.30 named The Palatine, in honour of the County Palatine, Lancashire.

Fifty-eight locomotives were taken over from the Waterford, Limerick and Western Railway in 1901, and of these sixteen were still at work. They have not been materially altered with the exception that the funnels, boiler fittings and splashers are now of Inchicore pattern, and the vacuum brake has replaced the steam brake with which the engines were originally fitted. The oldest class comprised eight 2-4-0 passenger engines designed by J.G. Robinson, and built by Dubs & Co. The .dimensions were: cylinders 17 in. by 24 in., coupled wheels 6 ft. and leadmg wheels 4 ft. dia., wheelbase coupled 8 ft. 6 in., total 15 ft. 10 in. boiler 4 ft. 05/8in. by 10 ft. 35/8 in., 210 tubes of 1¾ in., height of centre line 6 ft. 8 in., length of firebox 5 ft. 10in., heating surface, 1,000 ft2.

No. 274 was illustrated in the Locomotive  for 15 January p. 11. The remaining two engines from this line are 0-4-4 side tanks; No. 279 (W.L.W.R. No. 27) has cylinders 16 in, by 24 in. and coupled wheels 5 ft. 3 in. It was rebuilt at Limerick in 1899 from a 0-4-2 tender engine built by the Avonside Engine Co. in 1876, and is now classified E1,  No. 295 (W.L.W.R. No. 52) was built by Kitson in 1895, and has cylinders 16 in. by 24 in. and coupled wheels 5 ft. 6 in.; the classification E2.
Twenty engines were taken over from the Cork, Bandon and South Coast Railway in 1925, and ten of these are still at work, the most numerous being a class of eight 4-6-0 side tanks built by Beyer, Peacock and Co. between 1906 and 1920, and now numbered 463 to 470. These engines will be fully dealt with in a succeeding article dealing with the locomotives of the Cork, Bandon and South Coast Railway and its subsidiary the Timoleague and Courtmacsherry Light Rly.
Five engines were taken over from the Cork and Macroom Direct Railway in 1925, all of which are now scrapped; they included three 2-4-0 tanks built by Dubs, a 0-6-4 tank built by Barclay, and a 2-4-2 tank built by Dubs in 1891 for the Waterford and Limerick Raiway, which formerly bore the number 266 on the Great Southern and Western Railway; it became No. 6, C. & M.D. Rly. in 1914, and No. 491 on the G.S.R. before being scrapped.
Of four engines taken over from the Waterford and Tramore Railway but one, a 0-4-2 tank built by Barclay, is still at work, bearing G.S.R. number 486 and classification L1The cylinders are 15 in. by 22 in. and the coupled wheels 4 ft. 6 in. As has been mentioned already two of the ex M.G.W.R. class E 0-6-0 tank engines- have been transferred to this section to take the place of the Tramore engines scrapped.
Of the narrow gauge engines taken over in 1925 several have been scrapped; two of the systems, the Cork and Muskerry, and the Cork, Blackrock and Passage, have been closed to traffic. There were seven locomotives- at work on the Cork and Muskerry system in 1925, one of which was scrapped in 1927, and the remaining six followed in 1935. The four engines at work on the Cork, Blackrock and Passage system, were transferred to the Cavan and Leitrim section in 1934, but one of these has since been scrapped. The total number of narrow gauge engines still at work is 28, comprising six types, all of which have been described in these columns previously. llustrations:

Institution of Locomotive Engineers. Counterbalancing and its effect on the locomotives and on the briadges. 86-7.
Paper of more than ordinary interest was read by D.C. Brown, member, at the meetmg held on 23 February, in the Hall of the Institution of Mechanical Engineers. The President, Lt.-Col F. R. Collins, D.S.O., took the chair. Following are brief extracts from the paper.
One of the principal causes of impact on railway bridges is the hammer-blow due to the counterbalancing arrangements on the locomotives. As unbalanced reciprocating masses tend to shake the locomotive, and as the balancing of them gives rise to hammer-blow, the requirements of the locomotive engineer and the civil engineer are mutually opposed. The whole subject of counterbalancing, therefore, is a matter of compromise, and the purpose of the paper is to examine the problem from both points of view. When investigating. the methods of balancing locomotives, the principal features to be borne in mind are:-
(i) To balance revolving parts in the pair of wheels to which they belong.
(ii) To limit the "overbalance" (i.e., the proportion of reciprocating parts balanced) to the minimum necessary to ensure smooth running.
(iii) To distribute the overbalance as evenly as practicable amongst the coupled wheels.
(iv) To reduce to a minimum the weight of the revolving and reciprocating parts, particularly the latter. Special grades of high tensile steel are available for the manufacture of coupling and connecting rods and the use of these materials in preference to straight carbon steel results in an appreciable saving in weight.
(v) To ensure that the wheels as cast do actually comply with the designer's instructions. It has been found that the balance weights are often light, due to the metal being porous. This difficulty can be overcome by checking each pair of coupled wheels after mounting on the axle, and then correcting for any discrepancy.
The parts of a locomotive which move relative to the frame can be divided into two classes those which revolve and those which reciprocate.
The revolving parts can be fully balanced by means of masses in the wheels, and the degree of . balance remams constant at all angular positions during rotation of the wheels.
The reciprocating parts, on the other hand, can only act in the plane of reciprocation, which for the sake of simplicity will be assumed to be hori- zontal. If the obliquity of the connecting rod is neglected, as it usually is in locomotive balancing problems, the reciprocatmg masses will behave in the horizontal plane exactly as if they were revolvmg masses centred at the crank pins. They can, therefore, be fully balanced in this plane by revolving balance weights situated in the wheels.
The reciprocating forces, however, have no component except in the horizontal plane. Hence, m the vertical plane, the revolving masses used to balance them will themselves be totally unbal- anced, and will give rise to hammer-blow on the track. As far as the vibration of the locomotive is concerned the balance for the reciprocating masses can be distributed In any convenient manner amongst the coupled wheels. Revolving parts, however, can only be balanced in the pair of wheels in which they occur. This has often led to difficulty, especially in America where there has frequently been insufficient room in the small driving wheels to balance the massive revolving parts, and as a result heavy hammer-blows due to the underbalance of the revolving parts are not uncommon. In 1935 the Central of Georgia R.R. found 710 bent rails in a distance of only about 100 miles, and this was attributed to underbalanced revolving masses in the driving wheels of their 2-10-2 locomotives. Not only had the engmes been underbalanced when built but in service some of the lead in the balance weight had been lost, thus accentuating the defect. In British built locomotives it is usual to bal- ance the whole of the revolving and a proportion of the reciprocating masses. The actual balance crescents in the wheels are therefore made up, in theory, of two components, the balance for the re- volving masses, and the "overbalance," that is, the part which balances a proportion of the reciprocating masses. . When a live load passes over a bridge at speed it Imposes on the structure, in addition to its own weight, certain forces due partly to the irregulanty of the track and partly to features inherent in the design of the locomotive. The additional forces are:-
(a) Hammer-blow caused by the balancing of the reciprocating masses of the locomotive, or by lack of balance of the revolving masses.
(b) The effects of rail joint and other irregu- larities of the track and wheels.
(c) Lurching due to transverse unevenness of the track or transverse variations of the relative stiffness of the two rails.
(d) A number of minor irregularities· too small to be treated separately. . Although the underlying principles governing Impact effect were not fully understood until quite recent years, the presence of impact forces had long been realised and various means had been adopted to allow for them in designing bridges. As early as 1849, at a time when even the ele- mentary theory of stresses in girders was in its mfancy, a Royal. Commission which had been ap- pomted to enquire mto some disastrous failures of cast iron bridges, singled out "impact" and "fatigue" as two of the principal factors to be investigated. As a result of the report of this Commission the Board of Trade specified that cast iron girders for railway bridges should be so designed that their breaking strength was equal to three times the dead load plus six times the live load. In other words, they called for an impact allowance of 100 per cent. on all spans. We now know that this allowance was excessive, especially for the longer spans. Subsequently as a result of Wohler's experi- ments on fatigue a number of bridges were designed by means of "range of stress" formulae, so-called because the allowable stress depended on the ratio of minimum stress to maximum stress. Although these formula- included no direct allowance for impact, generally speaking they took care of its effects. Apart from other considera- tions, however, they were inconvenient to use as the dead weight of the completed structure had to be assessed before the allowable working stress could be determined.
These difficulties were overcome by the well- known "Pencoyd" formula and others of the same general form. The "Pencoyd" formula is  
I=300/300 + L
where I = impact allowance, i.e., the proportion by which the static load is to be increased.
L = the span of the girder in feet.
This formula was frankly unscientific in origin as it had been evolved merely by plotting values obtained from a number of existing designs. On the other hand, it represented practice that had proved reliable in service, it provided an impact allowance which decreased with increase of span and it was, moreover, simple to use. Consequently it gained wide popularity, but as it was found to provide an excessive allowance a number of variations were adopted.
The Indian authorities have been keenly interested In research on problems connected with bridge design, and the method adopted in their bridge investigation of 1925-1926 was to work on the basis of the natural loaded frequency of the bndge. By this means a basic theoretical formula was evolved and this was substantiated by experimental results. Then, by substituting in this formula for limiting conditions, a covering curve was obtained, giving the general formula:
Impact factor (for single track bridges) = 65/45+L
with a maximum of unity.
Where L = loaded length in feet.
How does all this affect the locomotive engineer? Does it make it possible for him to run heavier locomotives? The question is not so SImple to answer as may appear at first sight. As previously stated, the "Pencoyd" and some of the other forrnulae of this type are now known to have given extravagant values for the impact, and bndges designed wIth these excessive allowances are found to be capable of carrying loads greater than those originally permitted. Thus the Indian Railway Board, due to the adoption of the impact formula which they now use, were able to allow appreciable increases in axle loads.
After describing the manner in which hammer-blow affects the bridge structure and showing how a reduction in hammer-blow may enable the CIvIl engmeer to permit an increase in the static weight of the locomotive, the author then examined the trend of modern counterbalancing, also the effects on the locomotive of the disturbing forces. Instances of low proportions of counterbalance were given, various existing methods of limiting the counterbalance proportions were descnbed, and these were analysed from the point of vIew of both the locomotive engineer and the civil engmeer. A method of limitation combining the two methods, was suggested. '

C.H.E. [Cuthbert Hamilton Ellis]. Famouus locomotive engineers. IV. Archibald Sturrock. 93-6. 2 illlustrations (including portrait)
Somehow, in his departure from active work, Sturrock reminds me of that shining example in Hilaire Belloc's Cautionary Tales who:

"... thus became immensely rich,
And built the splendid mansion, which
Is called-
The Cedars, Muswell Hill;
Where he resides in affluence still."

For having departed from Doncaster, Sturrock seems to have taken but little interest in railway work, He did not, like David Jones, keep up the railway atmosphere by adorning his house with pictures of railway engines. As for residing in affluence, he was to do that far no less than 43 years, occupying the whole of his time until he was 73, in hunting, shooting and fishing. He went an shooting until he was 85. He was a queer personality. He was a hard worker and a clever engineer with plenty of imagination, yet locomotive engineering certainly did not provide him with his ultimate goal in life. He wanted to be, not a famous engineer, but an English squire with a large country house, a large town house, and nothing to do beyond killing game.
And in this he achieved his ambition. Young Erchie Sturrock, the Scotch mechanic, gave place to a kind of synthetic John Bull, noted for courtly manners, an English accent, and skill in field sports. Even in his busiest engineering days, he was well-known for his love of appearing in sporting attire, and having once left the Great Northern he was able to live the part as fully as he looked it. In keeping with this, he fulfilled the part of a Justice of the Peace with a kind of decorous gusto, and is reported to have said that he continued to sit on the Bench until he was so deaf that he was unable to hear the witnesses. The last we see of him is a strange old man with little hair and an immense white moustache, dressed in vigorous-looking checks with a high white collar and an immaculate stock. He died in his ninety-third year, on January 1, 1909. As we have seen, his ability, originality and activity were outstanding, and his early retirement leaves one speculating on what he might have done had he stuck to his guns as long as his tremendous vitality remained.

The four groups concerned, Journal and Thrust Bearings, Engine Lubrication, Industrial Appliances, and Properties and Testing.
The work of summarising the papers in Group II, Reciprocating Steam Engines, was undertaken by W.A. Stanier, and the following is an abstract of his remarks.
The French and German State Railways considered that various grades of superheated cylinder oil were desirable according to the degree of superheat obtaining in the cylinder, whereas the Canadian National and English railways employed only one grade. Of the opinions expressed for superheated cylinder oils the majority favour com- pounded oils since it is considered that at the temperature of superheated steam the oil becomes much less viscous and the fatty oil is partly decomposed, the decomposition products helping in the formation of stable and resistant boundary films. Oils A and B as quoted by the French State Railways, and the valve oil as used by the Canadian National Railways, were generally similar to those in use on the English railways:
Of special interest was the use of emulsified oil, prepared by the German State Railways, from the superheated steam cylinder oil and lime water for use in locomotives working under medium loads. With regard to the oils used far journals, motion, etc., the German Railways used winter and summer grades, as did certain of the English railways, while the Canadian National and the Other English railways prefer the same grade throughout the year; one of the latter railways considers that the inoonvenience of changing the grade of oil twice a year outweighs any possible advantage and in its experience no advantage was obtained when the thicker summer oil was used. It was the practice of the English railways to use a mineral oil containing a percentage of refined raw rape oil, the percentage depending on the different classes of work and the experience of the companies concerned, while the German State and Canadian National Railways use a mineral oil only. The German State Railways use an oil of higher viscosity far lubricating the journals and gear of streamline locomotives, this also being the experience of certain English Railways.
It was the practice of the German State Railways to use wick trimmings for supplying the oil to the valve gear, connecting and coupling rod bushes, while the English railways used worsted trimmings for the valve gear and either worsted trimmings, needle trimmings or felt pads for the rods. When needle roller bearings are fitted to the valve gear in Britain, grease was used as the lubricant. On the modern locomotive the pump lubricator had generally superseded the hydrostatic system far supplying the lubricant to the cylinders and the general principles employed by the German and French State Railways and the English railways would appear to be similar as regards the position of the pump, the provision and position of back pressure valves, etc. The English railways, however, do not favour the branching of lubricator pipes as indicated by M. Chatel, of the French State Railways, for use under certain circumstances. A point of interest was the recornmendation by M. Chatel that the high pressure cylinders should be lubricated towards the dead centres, where the piston is almost stationary, so that the piston rings can receive plenty of oil. It is the English practice that when a feed is taken direct to the cylinder barrel, it should be situated in the middle of the stroke.
Most of the French Railways injected steam or water into the cylinder exhaust to reduce the temperature of the gas when coasting, and they had under consideration an automatic device to come into operation when the driver closes the regulator, whereas the English railways attain the same end by allowing a "breath" of steam to enter the cylinder by means of the regulator or through the anti-carboniser or atomiser.
The analysis and mechanical tests of cast irons for piston rings and cylinders given by M. Chatel correspond to those generally in practice on the English railways, except for the higher percentage of silicon and the lower percentage of phosphorus, One railway in this country was, however, experimenting with a lower percentage of phosphorus, also with the use of nickel and chromium.
Modern French locomotives were fitted with four rings per piston head, the German with five, while the English railways favour two or three, but experiments were being carried out in Britain with an increased number of rings. Piston ring wear varied considerably according to the class of locomotive and the type of work on which engaged. For express passenger compound engines Chatel gives mileages of 12,500-25,000 for the high pressure cylinders and 28,000-37,600 for the low pressure cylinders at which the rings are replaced. On one English railway the piston rings of a three-cylinder (simple expansion) locomotive were changed at 40,000-45,000 miles.
The comparison of oil consumption is difficult since the consumption is governed by working conditions and is not on an entirely quantitative basis: Nordmann and Robrade give a figure of 0.7 pint per 100 miles for a "series- 03" (2-cylinder) locomotive, the figure for the English railways for a 2-cylinder locomotive being 1.0-1.2 pints per 100 miles.

Obituary. 97
Death of Samuel' John Sarjant on 18 February, at the age of 81 years, at Penmaenmawr. He commenced his career in the locomotive drawing office of the Midland Railway at Derby in 1872 under Matthew Kirtley, at the age of sixteen, and spent seven years in the works. He then took service with the Lancashire and Yorkshire Railway in the drawing office at Newton Heath and as assist, loco. foreman under W.. Barton Wright. In 1885, he became distriot loco. superintendent of the Great Indian Peninsula Railway at Lonaula, and subsequently at Igatpuri, both depots being at the top, of the Ghats. He was then appointed assistant locomotive superintendent at Parel Locomotive Works, Bombay, and on the retirement of R.L. Trevithick, took charge- of the locomotive, carriage and wagon departments. The carriage and wagon sections were separated later. Sarjant retired from the position of Locomotive Superintendent of the G.LP. Rly. in 1915. He was responsible for many improvements in the locomotive practice of the G.LP. Rly., including the introduction of superheating. Under his charge the locomotive stock was kept in the highest state of efficiency. He was a member of the Institution of Civil Engineers and acted as chairman of the Locomotive and Carriage Superintendents' Committee of the Indian Railways from 1908 to 1912, Sarjant was a keen locomotive historian and gave us considerable assistance in preparing the Locomotive Magazine serial articles on Great Indian Peninsula Railway locomotives.

Alfred Whitaker. 97
Formerly Resident Locomotive, Carriage and Wagon Supt. of the Somerset and Dorset Joint Railway, died in his 92nd year on the 5 March. at his residence at Bath.. Whitaker joined the Midland Railway in 1860, as a pupil of Matthew Kirtley, then locomotive superintendent. On completion of his training at Derby, he was given charge of various locomotive depots on the system, first at Lancaster, and afterwards at Bradford, Carlisle and Leeds. He was the first District Supt. at Carlisle when the Midland line was opened in 1875. Subsequently he was given charge of the Leeds district, where he remained until he was appointed to the S. & D.R. in 1889. He remained with that railway until his retirement in 1911. During his term of office at Highbridge he was responsible for the re-building of the shops. He was the inventor of the tablet changing apparatus for single line working which bears his name, as well as a water leve1 indicator for locomotive tanks.

Correspondence. 98

Bishop's Castle Railway.  T. R. Perkins.
As the writer of the article on this line which appeared in the issues for October, November and December, 1930, I was much interested to read the notes on Carlisle, which appeared last month. By a fortunate accident I am able to clear up the question as to where the old locomotive was at work near Blisworth. A few weeks ago I discovered that a lady who has lived next door to me for the last 30 years or more was well acquainted with the engine in its "contractor " days, her father having been an official of Mr. Thomas Nelson, its original owner. She tells me that the work upon which they were engaged in 1880 was the widening of the L. N.W.R. main line between Bletchley and Roade, together with the new line from the latter place to Northampton. During that period her parents resided at Roade, and she—a child at the time—was frequently given a ride on Carlisle's" footplate. With reference to Parliamentary trains: the distinction between "third class" and "parliamentary" fares was certainly in force on portions of the G.\V.R. until 1893. In that year, when living at Wolverhampton, I sometimes walked home on Sundays, returning to business by train next morning. If I caught the 07.38 the fare from Kidderrninsrer to Wolverhampton was 1(6, but a's I had over three miles to walk to the station I usually travelled by the 08.05, by which the fare was 1/10. In the former case my ticket was green; in the latter, buff. By 1896, however, the Parliarnentary fare had become standard by all trains on the G.W.R.

The Dorset Central  Railway. Reginald B. Fellows. 98
Although the matter is not of great importance will you allow me to correct a mistake in the date given for the opening of the Dorset Central Company's line from Templecornbe to Cole in the interesting article on the Somerset and Dorset Railway published in January? The date given for the opening from Templecombe to Cole was Novernber 1861, as in Bradshaw 's Railway Manual of 1862 and subsequent issues. Contemporary newspaper accounts, however, show that although the directors stated at the half yearly meetings in 1861 that the line would be opened in the autumn, it was not actually opened for traffic until 3 February 1862. A formal opening by the directors took place on 18 January but, as some alterations were insisted on by the Government Inspector, the use of the line for public traffic was postponed for a fortnight. From 3 February through train service from Ternplecornbe, through Cole, to Burnham commenced.

See also page 96. Some 29 British and 22 foreign societies agreed to colaborate and, as a result, 136 paprrs were received. The papers dealt with the major problem of the subject—practical and theoretical and the correlation of these aspects—the application of bearing design, the relationship of academic research and trade practice, statements of current views on bearing metals, and the significance of laboratory tests, including wear and friction tests. The papers, together with the summaries by the reporters, the accounts of the discussions, and the collated replies by the authors, constitute an invaluable compendium of current information on lubrication, and an important addition to its literature.[KPJ personal memory of Stanier being involved].

Four locomotives built by North British Locomotive Co. with Sentinel engines. Each totally enclosed engine had two 11 x 12in cylinders driving wheels of 3ft 8¾in diameter. The driving wheels were not coupled: thus in Whyte notation they were 2-2-2-2. They eliminated hammer blow. They had 200 psi Belpaire boilers which were identical to those used in 4-4-0 locomotives supplied in 1937 (see LM, 43, 304). The valve gear was modified Hackworth. An industrial 2-2-2 saddle tank with two Sentinel engines is also described.

Locomotivve stock returns, 1937. 131-2. table
Accompanying table shows in summary form the alterations in the stock of steam locomotives operatmg the four main railway groups dunng 1937. When dealing with the figures for 1936 (see Volume 43, p. 116) it was pomted out that the L. & N.E.R. totals did not include the M. & G.N. Joint stock: the present statement however imcludes 82 engines. taken over, also 18 tank engines from the London Passenger Transport Board.
At the close of 1937 the total number of tender engines was 11,909 , only 25 less than twelve months earlier, while the tank engines numbered 7,770, being a reduction of 113 for the year. (The reduction in tender engines is however considerably more than 25 if the 1936 figures were increased to show the engines received from the Joint line).
Of the 11,934 tender engines in stock at the close of 1936, 414 were withdrawn last year; and of the 7,883 tank engines then in stock 287 have been taken out of service: on these figures the average life of a tender engine works out at nearly 29 years, and of a tank engine 27·½ years.
Tender engines added G.W.R.: Sixty- three 4-6-0 passenger (thirteen Castles, ten Halls, forty Granges), and nine 4-4-0 Earls.
L. & N.E.R.: Nineteen A.4, eleven B.17, twenty V.2, eight K.3, one K.4, ten J.39, and forty-three passenger and twenty-seven goods engines of various classes from the M. & G.N. line.
L.M. & S.R.: Five 4-6-2, one hundred and fifty-three 4-6-0, twenty-seven 2-8-0, and fifteen 0-6-0.
Tank engines added .G.W.R.: Three 2-8-2T converted from 2-8-0T (Nos. 7240-2), two 2-6-2T (Nos. 4120/1), and seventy-three 0-6-0T (Nos:3715-64, 6430-9, 7417-29).
L. & N.E.R.: No new engines were built during 1937 but the following were received into stock: ex M. & G.N. J.R., 4-4-2T Nos. 09, 020, 041, and 0-6-0T Nos. 015, 016, 093-099; ex L.P.T. Board, 4-4-4T Nos. 6415-22, 2-6-4T Nos. 6158-63, and 0-6-4T Nos. 6154-7. L.M. & S.R.:
Twenty-seven 2-6-4T ( Nos. 2476-94, 2610-7) and thirty-nine 2-6-2T (Nos. 145-172, 185-195).
Engines withdrawn..-While it is not necessary to give a complete list of the engines condemned, the more interesting withdrawals may be briefly referred to. G.W.R.: Three Abbeys for conversion to Castles; nine Dukes to balance new Earls; and ten Bulldogs; also thirty-seven 43xx to balance new Granges. All the Swindon-built 2-4-0 passenger engines had now gone, though the three taken over from the M. & S.W.J. line were still in service. L. & N.E.R.: All the A.2 (Raven Pacifics) and the C.11(Reid Atlantics) had been condemned, and the last of the N.E. 2-2-4T had gone, also the last Ivatt 0-8-0 and Wheatley 0-6-0 goods. Fresh classes added to the condemned list during 1937 included B.15, C.12, G.9, G.10, J.62, T.l, as well as M. & G.N. Classes B and D. L.M. & S.R.: Of the 4-6-0 type the Oban Bogies were extinct, and several more Claughtons, Princes and 19 in. goods had gone. The H.R. Big Bens and the G. & S.W. 4-4-0 and 0-6-0 had all gone, also the Caley, 2-6-0. As regards tank engines, the withdrawals of Crewe 4-6-2T and 4-4-2T and of Derby 0-6-4T had been heavy, and all the N.S.R. 0-6-2T and 0-6-4T had been taken out of stock. S.R.: The withdrawals included eight Stirling 4-4-0 and four Adams 0-4-2. Two of the three large-boilered 0-4-4T had gone (Nos. 126 and 2396) and four more Stroudley 0-4-2T. No. 299 was the only surviving C.8 4-4-0 (the original Drummond series). No. 2305 is the second of the Marsh goods to be cut up.

The Empire Exhibition, Glasgow. 132
At all exhibitions use is made of the miniature in display and publicity and we understand the Empire Exhibition at Glasgow, opening in May, will be no exception to this rule. Bassett-Lowke Ltd. will be represented with some fine examples of their exhibition work. A huge model of a block of the earth's surface about 600 ft. deep will show to scale the coal seams, the way these are worked, and the processes the coal goes through before it is ready for transport on the railways. The model is to a scale of ¼ in. to the foot and will be the centre of attraction in the Government Pavilion. .
To railway enthusiasts probably the most interesting exhibit would be in the British Railways Pavilion where Bassett-Lowke Ltd. were constructing a working model railway. This consisted of over 600 ft. of track with points, crossings and other details, and a representative train of each of the four British railways. The track will be laid in the form of a large arc in a prominent position in the Pavilion, with the operating section at one end and a return curve at the other. The line will pass through a background of scenery representing districts which each railway Serves. The track will be 17#188; in. gauge, electrically operated, and signalled by colour light signals, but at the operating end where the trains are marshalled, the upper quadrant semaphore type will be used.
A complete passenger train of each company will be shown — the models being as follows — L.M S., Coronation Scot, L.N.E.R. Coronation, G.W.R. Cornish Riviera, drawn by the locomotive King George V, whereas the Southern Ry. will show their latest development in electric traction, the all-electric Brighton Belle.

At the annual general meeting of the Railway Club held at the Royal Scottish Corporation Hall, Fetter Lane, the President, Kenneth Brown, delivered his Presidential Address entitled "Railways. at Law." Describing his address as grains of railway history gleaned from law reports, Brown first referred to the case of the King v. Edward Pease 1832. This case established the legal right of railways to be operated by steam. Next the prolonged litigation between Bacon and the Newcastle and Carlisle Railway was dealt with. The ambitious Manchester and Milford Railway was involved in numerous legal disputes, and the President referred to reports of Chambers v. M. and M. Ry., Carmarthen and Cardigan Ry. v. M. and M. Ry. Finally the closing of the Potteries, Shrewsbury and North Wales Railway was descriobed and the eventual acquisition of this line by the Shropshire and Montgomeryshire Light Railway.

D[ewhurst], P.C. L.M.S.R. locomotives: a history of the Somerset and Dorset Joint Railway. 157-9
Continued from page 83). The first locomotives and rolling stock must have been ordered by the Somerset Central Rly., as the working of their line by the Bristol and Exeter Rly. on the broad-gauge had been definitely determined by August 1861, and ceased on the 28th of that month. At a general meeting of the shareholders in the same month it was stated that the narrow-gauge would be laid immediately on the expiry of the B. & E. Rly. lease—which itself expired in August 1861—and mean- time the traffic was worked on the original portion of the line by means of broad-gauge stock hired from the B. & E. Rly. until the opening of the Glastonbury to Cole section on 3 February 1862, and the completion of the "mixed" gauge. In the special House of Commons Return of July 1861 the locomotives and other rolling- stock of the two lines, as on 31 December 1860, is given as follows:-" Dorset Central, see L. & S.W. Rly."; "Somerset Central, see Bristol and Exeter," hence it is clear that the working of each line was at the time entirely in the hands of the operating companies. The published time-tables of the Somerset Central Rly. for July 1861, giving all the passenger trains between "Wells and Burnham, have a foot-note respecting certain trains arriving at Highbridge from Wells: "This train runs to Bridgwater to catch up and down expresses returning almost immediately," thus indicating broad-gauge working and co- -operation right up to the eve of severance. The extension to Cole being opened on Feb. 3, 1862, the Somerset Central Company's own narrow- gauge engines were in service by then.
The working of the Dorset Central section proper, i.e., from Wimborne to Cole, by the S. & D. company's own locomotives commenced in August-September 1863, when the two portions of the recently amalgamated lines were connected.
The first locomotives built for the companies were a number of 2-4-0 tender engines by G. England & Co., of Hatcham Ironworks, New Cross, London; they were built in 1861, being mostly delivered in November of that year and numbered 1 to 7, and, whilst having a few variations in details, were practically identical. Their makers' numbers—if any—are unknown. They are illustrated by Fig. 7, and their principal dimensions were:-Cylinders 15 in. by 18 in.; coupled wheels 5 ft. 0 in. dia. Leading wheels 3 ft. 6 in. dia., and a wheelbase of 13 ft. 3 in., equally divided. As will be seen, the engines had an unusual form of "mixed" framing, and the tenders were on four wheels, having outside framing very similar to the G.W. Ry. pattern current at that period. The working pressure of the boilers was probably 115 lb. per sq. in.
These engines had some distinctive features for the time they were built, although one—the dome-less boiler—was probably derived from the practice of their adjacent railway neighbours, the Great Western Railway and the Bristol and Exeter. The other feature, the mixed framing, comprised an apparently weak-looking .arrangement of outside framing to the leading wheels combined with springs below the runnmg plate; that such weakness proved in practice to be the case is probably confirmed by the fact that when such of this class—two of G. England's and two later ones, of the same pattern, by the Vulcan Foundry—were rebuilt at Highbridge, particularly strong outside framing, etc., was provided for the leading wheels. The boiler was flush-topped, having a somewhat small manhole on the back ring and a pair of spring-balance safety-valves over the firebox, being fed by injectors placed at the sides of the firebox outside the cab, the safety-valve casing and chimney-cap being polished. The link motion had the reversing shaft below; the coupling-rods were of the adjustable, cottered type, and the driving and trailing springs were under-hung and provided with equalizing beams between. As built, there was no brake on the engine, whilst the tender was provided with a hand-brake, applying wooden blocks to the front and rear of both the left side wheels. A bent- plate weather-board, in some cases only very slightly protecting the enginemen, was upon the engine, and upon the tender was a fairly substanstantial "straight-up" weather-board, which, together with sand-boxes upon the front end of the tender (placed outside in an un- usual position) delivering sand between the engine and tender- wheels, indicating that the engines in practice ran more or less indifferently in either direction.
These engines were certainly of small size, and if, as is probable, their boiler pressure was 115 lb. psi.—it would not have been more—their rated tractive force at 80 per cent. would only have been 6,210 lb.
Engines 1, 3, 4 and 5 were sold in 1874-5—one in 1874 and three in 1875—to Messrs. Fox, Walker & Co. of Bristol, presumably in part payment for engines being supplied by them to the S. & D. at that time. Of these, Nos. 1 and 5 went to the Bishop's Castle Railway, one lasting until as late as 1905, but the other ending service about ten years earlier.
It has not been possible to ascertain definitely the disposal of the other two. It has been stated that a Somerset & Dorset engine was sent by Fox, Walker & Co. in the early 1870's to the East and West Junction Railway, but refused by them, and this was possibly one of these engines; it also appears very probable that No. 3 of the E. & W. Junction Railway was one of these ex-S. & D. Railway engmes.
Engines 2, 6 and 7 were taken over by the Joint line in 1875, No. 2 having been then replaced and become 2A; it was renumbered 25 in 1876, 25A in 1881, and was scrapped in 1882. No. 6 became ?6 in 1876, 26A in 1881, and was scrapped ln 1889.
This latter engine had been converted to a side-tank some time after 1875 and is so illustrated in Fig. 2, from which it will be seen that besides the alterations arising out of the elimination of the tender, that is to say the provision of tanks and bunker with the necessary frame extension to carry the latter, and the addition of a rear weatherboard and a cab-somewhat of the pattern of early G.S. & W. Rly. Iocomotives—the provision of brakes to the driving and trailing wheels having double-plate hangers and pull-rods outside the wheels, no changes were made to the original structure of the engine or boiler, even the equalizing between the driving and trailing springs being retained. The illustration is remarkable for other interesting features: that the leading wheels are obviously of larger diam, than the 3 ft. 6 in. (being about 3 ft. 9 in.) of the rest of the class as built and as rebuilt, and the view being one of the few known showing an engine number still upon the front of the chimney in the time of the "Jaint" ownership. Old No. 2 when running as No. 25 had a similar cab and also the number an the front of the chimney.
No. 7, having similarly become 27 and 27A, and withdrawn about 1884, was completely reconstructed as a 2-4-0 side t:ank. in 1888, at Highbridge. It is Illustrated thus in FIg. 3, showing the drastic alterations made, including the outside framing and springs above the running-plate for the leading wheels. The dimensions are given:
Cylinders, 16 in. by 18 in.
Wheels: leading dia. 3 ft. 6 in.
Wheels: coupled, dia. 5 f t. 0 in.
Wheelbase,. adheslve. 7 ft. 4 in.
Wheelbase total, 14 ft. 2 in.
Boiler, length of barrel 8 f t. 9 1l1 .•
boiler dia., 3 ft. 11 in.
boiler, height of centre above rails, 6 ft. 4¼ in.
Inside flrebox~. length, 4 ft. 0 in.
Heating surface :-170 tubes, l¾ in. outs. dia., 712 sq. ft.
Firebox 81 sq. ft.;,
total, 793 sq. ft.
Grate area, 13 sq. ft.
Boiler pressure, 140 lb. per sq. in.
Tank capacity, 589 gallons.
Weight in working order, 35 tons, 9 cwt., 1 qr.
Wheelbase :-Leadmg to driving, 6 ft. 10 in.
Driving to rear coupled, 7 ft. 4 in.
Rated tractive force at 80 per cent 8,602 lb.
From which it will be seen that the cylinders were increased in diameter by 1 in. and the coupled wheelbase by 6 in. to 7 ft. 4 in. The boiler far this conversion was built at Highbridge, and had the dome aver the firebox, with a pair of spring-balance safety-valves thereon; apart from the unusual position of the dome the whole design was up to date for the time it was carried out, and included power and hand-braking upon the coupled wheels, with double-plate pattern hangers, with outside pull-rods and brake-shaft to rear of the trailing wheels; also, either at the time or within a year or so afterwards, the vacuum brake equipment in the usual S. & D. Joint manner. The equalizing of the driving and trailing springs was not perpetuated, and the new 7 ft. 4 in. coupling-rods had plain bushed ends; the dome casing and chimney cap were polished. When another boiler was required in the early 1900's, the usual M. Ry. style of dome, safety valves, etc., was adapted, and Fig. 4 shows the engine as at that period; the safety-valve casing and chimney cap being polished, but the dame painted. It lasted until 1925, spending the latter part of its life shunting at Highbridge Wharf.

The Duke of Sutherland. 159
Duke was entitled to run his own private train over the former Highland Rly. line between Inverness and Wick. This privilege was exercised on April 29th. when the Prime Minister made the journey from Brora to Inverness on the footplate of the Duke's private tank locomotive Dunrobin with the L.M.S. Northern Division official saloon attached. Speed was restricted to 30 m.p.h. The journey took 3½ hours with three stops for water.

Kitsons of Leeds, 1837-1937. Edward Kitson Clark, London: Locomotive Publishing Co. Ltd.
Many to whom the cessation of the production of lccomolives by the well known firm of Kitson and Co. after a century of continuous activity was a matter of sincere regret will find some consolation in reading this interesting memoir from the pen of Col. Kitson Clark, It is not in any sense a catalogue of events, but a pleasantly told story that will appeal to a much larger public than that mainly interested in locomotives. The beginnings of the firm are first dealt with, commencing with Todd, Kitson and Laird and then on through Laird, Kitson and Co., Kitson, Thompson and' Hewitson, Kitson and Hewitson, Kitson and Co. and finally Kitson and Co. Ltd. Here it may be noted that the Railway Foundry, first established by Shepherd and Todd, after the last named had broken away from the original firm, and later continued by Fenton and Craven, E. B. Wilson and Co., and finally Manning, Wardle and Co. came back to the fold in 1927 when the latter firm was absorbed by Kicsons, The importance of this great business to the city of Leeds can hardly be over-estimated, and it is fitting nhat iJts story should now be given by one who has been actively associated' with it for so long. After dealing briefty with some of the many different types of locomotive built by Kitsons and the railways to which they were supplied, the writer proceeds to detail certain other of the firm's activities and follows with special chapters on Tram and Articulated locomotives. The former were for many years a Kitson speciality and were noted for the particular type of valve gear with which they were fitted whilst Kitsons have long been known in connection with the articulated locomotive by their Interest in the Kitson-Meyer type of which they supplied many examples to various parts of the world. The story of the Kitsori-Stil! locomotive is given in some detail and its fortunes or misfortunes fully discussed. The chapter on the Education of an Engineer makes delightful reading and will be thoroughly appreciated by all who have been through the mill themselves. The book finishes with brief notices of some of the chief personalities of the firm and is plentifully illustrated by excellent reproductions of locomotives and other pictures of interest in connection with the business. Throughout it bears evidence of the great care bestowed upon its compilation and' production though an unfortunate slip, the only one we have noticed, occurs on page 30 where the Sharp firm is stated to be "now Neilson and Co."; this of course should be the North British Locomotive Co. Ltd.

The metallurgy of a high-speed locomotlve...London: The Railway Gazette. 163
Sixteen page brochure is a reprint of articles published in The Railway Gazette, and gives from a metallurgical point of view, a survey of the materials used in the construction of the streamlined 4-6-2 express locomotives of the L.M.S.R. with details of the analyses and tests. A folding plate shows details of the boiler and firebox, coupling and connecting rods, crank axle and piston valves.

G.W.R. engines: names, numbers, types, classes, etc. W.G. Chapman. Published by the Great Western Railway, Paddington. 163
All who are interested in G.W.R. locomotives and especially the number and name collecting fraternity, will welcome this new edition of the G.W.R. engine book. Since the last issue (1935) appeared, over 150 deletions, alterations and additions have ,been necessary in the list of named engines alone. In the new edition these amendments have been embodied, while the text has been re-arranged and new features added. An alphabetical index to G.W.R. named engines is included. One section is devoted to details of the standard tender and tank types of G.W.R. engines, with illustrations and diagrams. Further subjects dealt with are the activities of Swindon Works, also passenger and freight train names, famous high-speed G.W.R. expresses and train speeds, and also the development of locomotive power on this system.

How to recognise Southern Railway locomotives. R.W. Kidner. Sidcup: Oakwood Press. 163
An interesting little book on somewhat novel lines showing the external features of the various S.R. locomotives. The production is somewhat crude but the salient details are emphasised, which should enable anyone to readily identify the different classes. From this point of view, the booklet is to be recommended, but there are many errors in the letterpress which, considering these particulars are found in other publications on the S.R. locomotives, can only arise through imperfect checking. For instance, all the C2 class goods engines were built by the Vulcan Foundry, not at Brighton, whilst none of the N1 class was built at Brighton. All the E2 class shunters, too, are on the Eastern Section, whilst many of the dates given are incorrect.

Particulars of the hours of admission are given and a map of the city is included.

New non-stop Sunday train, London & Edinburgh. 163
The L.N.E.R. announce that the world's record non-stop run between London and Edinburgh will be made on seven days a week during the summer. Previously this record has been maintained by the Flying Scotsman on weekdays only. In view of the considerable passenger business anticipated in connection with the Empire Exhibition at Glasgow, it has been decided to introduduce a non-stop service between the English and Scottish capitals on Sundays also during the summer of 1938. The train will be known as the Sunday Scotsman and will leave the London and Edinburgh termini at 11.00, performing the journey in seven hours. The 10.00 departure time for the Flying Scotsman on weekdays will, of course, be continued; this is a treasured tradition of the L.N.E.R. as the Flying Scotsman has left King's Cross at this hour since June 1862, and this timing has become the foundation stone on which the timetable is built up. For the service new locomotives and carriages are being built at Doncaster, and these will be used for both the Flying Scotsman and the Sunday Scotsman services. The locomotives were being streamlined.

Facts about British Railways. 163
The 1938 edition of this booklet issued on behalf of the British Railways was available upon application to the British Railways' Press Office, St. Ermin's, Caxton Street, Westminster. The figures given are for 1937 and the information has .been summarised to illustrate the various directions in which the railways have been active during ,the year, and the ways .in which they cater for the needs of the trader and the traveller. Facts, figures and statistics are given covering the financial results, traffic' receipts and expenditure, passenger and freight services, ancillary businesses, improvement schemes, maintenance, employment and other features of railway activity. Comparison with the previous year shows a steady increase in business. The number of journeys made amounted to 1,215,648,000, as compared with 1,179,462,000 an increase of 36,186,000. 15,672,000 more excursion, monthly return, weekend and similar cheap tickets were issued and an increase of over 10,000,000 was recorded in the number of workmen's ticket journeys. Season ticket journeys also increased by nearly 8,000,000. 766,000 more parcels were forwarded dur- ing 1937 as compared with 1936, whilst freight tonnages in- creased by 16,153,000. Of this increase, 1,919,000 tons re- presented general merchandise traffic, 3,755,000 mineral traffic, and 10,479,000 tons coal, coke and patent fuel. The mileage- covered by both passenger and freight trains was also con- siderably in excess of the previous year. Passenger trains. covered a total of 281,112,000 miles, an increase of 5,565,000 miles, whilst freight train mileage totalled 140,109,000, an. increase of 4,712,000 miles. Passenger and freight engines covered 15,095,000 .rnore miles than in 1936, with a total of 594,864,000 miles. Interesting figures are given of some of' the annual purchases made by the railways, wh.ich include 15,017,000 tons of coal, 14,439,000 cubic feet of timber, 5,130,000 sleepers and crossing timbers, 18,431,000 bricks, 2,348,000 yards of cloth for uniforms, 7,240,000 gallons of' lubricating oil and 29,968,000 gallons of petrol and oil fuel;. whilst no less interesting are the details of numerous items. under the heading of "equipment" owned by the railways.. such as 10,297 signal boxes, 141 water troughs, 1,042 tunnels.. 6,683 passenger and 6,909 goods stations, and 50,407 horses.

Obituary. 163
Death at age of 76; of F.G. Wrighr, who retired in 1922 from the position of Chief Assistant to the Chief Mechanical Engineer of the G.W.R. He was the son of Mr. T. Houghton Wright, locomotive superintendent of the former South Devon Railway, and one of Sir Daniel Gooch's pupils. Wright entered the Gloucester shops of the G.W.R. as an apprentice in 1876, and was moved to Bristol three years later. He entered the, drawing office at Swindon in 1882, and became chief draughtsman in 1892. In 1896 he became assistant works manager at Swindon, and manager in 1901, and Chief Assistant to Churchward in 1903.

James Watt. 163
One of the oldest, if not the oldest, of Scotland's engine drivers, James Watt, passed away on 22 March in a nursing' home in Craigie, Perth, after a very short illness. Born in 1857, his father was a driver on the old Forth and Clyde Railway, afterwards transferring to the Fife and Kinross. Railway, a short single line connecting the Kinrossshire Ry. at Hopefield with the Edinburgh, Perth and Dundee Railway at Ladybank Junction. On this line young Watt, then in his early teens, used to fire for his father on either the Falkland Palace or the Loch Leven, the two four-wheeled locomotives which comprised the stock of the company. The Fife and' Kinross appears to have been one of the early lines that existed in a chronic state of impecuniosity and Watt used to. tell many very interesting tales of going with his father on one of the locomotives, collecting what money was available in the tills of the various stationmasters the day before pay day. Watt joined the North British Railway in 1876, and drove one of the 185 class on goods trains across the first Tay Bridge and later generally over the system, retiring some. fifteen years ago.

The Belleville washer spring.  P.C. Dewhurst. 164
The article (in your issues for October and December last) ·illustrating possible usages for the above-mentioned washer- spring are very interesting as suggesting the various advantages and possible applications of it. In fact the only comment which—at first sight—appears applicable is "why was it not done before," in other words,' in view of the facts stated in the article that for some 30 years the possible uses of these washer-springs have been known, why their apparently obvious advantages have not been seized upon by designers of locomotive and other machinery and vehicles. There appears to the writer an evident fundamental—mechanical and not metallurgical—disadvantage as follows: to be effective a series of these washers must be placed either upon a spindle or in a case, or both, and it is obvious that in use the immediate tendency is for each washer to move in a lateral direction alternately one way and another, as far as either the spindle or the case—or both—will allow. In. the case of using a spindle alone, to provide for flexing of the washer. there must be a clearance between the spindle and the hole, and it is evident that movement of the washer will tend to occur and thus cause "biting" into the spindle in service. If it is attempted to eliminate this defect by adding a cylindrical case outside the washers, again sufficient clearance (the diameter of washers when flat plus necessary freedom) must be provided, and this will allow the washers to get out of line and bite into the case and/or the spindle. The writer has not used these washer-springs, but the prac- tical points above-mentioned may explain the reluctance to use what otherwise appears an obviously advantageous mechanical contrivance. It is of course evident—as indeed is mentioned in the final paragraph of the article—that flatting the bearing edges would reduce the tendency I have referred to; but to be effective this flatting would have to be carried to an extent seriously reducing the effectiveness of the device as a spring, before it would become sufficiently effective in preventing the washer-springs getting out of line.

Trade notes and publications. 164

Ruston and Hornsby Ltd. 164
Lincoln firm's Locomotive catalogue—The Ruston oil-engined locomotive is now made in five sizes, ranging from 11/13 b.h.p. to 44/48 b.h.p. One important advantage claimed for this locomotive over other types is its low running cost, light fuel oil at 6d. per gallon being used. It is fitted with a Ruston four-stroke vertical oil engine which has proved an economical proposition when installed as a portable unit. Other features of the machine are the constant mesh 3-speed gearbox, and the method of drive and of springing which obviate chain snatch. Full particulars are given of the various sizes of locomotives, with the respective hauling capacities, etc. The illustrations show the wide variety of jobs for which these machines are em- ployed in all parts of the country as well as overseas. Ruston locomotives are working in intense cold near the Arctic circle and in the fiercest heat as on the shores of the Dead Sea, as well as in many tropical countries.

Railok. 164
A new half drop window for bulkheads, doors, etc., known as the "Railok," is shown in a leaflet issued by Beckett, Laycock and Watkinson Ltd., of Acton Lane, N.W.10. It is of frameless glass and extremely light and can be fitted between pillars of minimum depth. Consequently it is very suitable for sliding doors. It is locked positively in the closed position, along the whole length of the guard rail.

O.J. Morris. Eastleigh Railway Museum. 180-3. 5 illustrations
Brief historical background: Rouse-Marten, Rosling Bennett, Archie Sturrock and Sir William Acworth attempted to form the Railway Musem Assocition. It had long been argued that if a National Railway Museum was established it could not be historically representative [KPJ this remains true]. By 1938 the LNER had established its Museum in York; the LMS had preserved two locomotives; London Transport had preserved one bus. The Southern Railway was making a start at Eastleigh in the Paint Shop with a Whitworth screw cutting machine sent to Nine Elms in 1858 of a design patented in 1834 (BP 6566/1834). There are two illustrations of this machine (KPJ: was this lost during WW2?); sectional wooden model of Beattie mid-feather firrebox patent BP 259/1854; also feed-water heater pump as fitted to 2-4-0T No. 247; Mansell wheels (illustrated) developed by Richard Christopher Mansell; Vortex blast pipe off A12 0-4-2 No. 642; gilded door fittings from LSWR Royal Train (illustrated); Adams 4-2-2 drawing (illustration: reproduced)

Railway electrification. 187
Sir Ralph Wedgwood, Chief General Manager of the L.N.E.R., contributed a talk to the B.B.C. Transport series which was broadcast on 12 May 1938. He dealt with the possibilities of speed if the lines were electrified. It was true that an electric locomotive could haul a heavy train at a more constant speed than a steam locomotive, and that over a varied line it could maintain a higher speed between point and point. But it was "5 a weight carrier rather than a flier that the electric locomotive would do its best work. Suburban electrification, dependent on the multiple unit, not the electric locomotive, was a proved success, where the passenger traffic was heavy and the goods traffic light. This was particularly the case with London, South of the Thames, where there had grown up by far the largest system of suburban electric railways in the world.
North of the Thames progress had been less rapid, but was making great advances now that the main line companies. and the London Transport Board had pooled their suburban interests. Apart from London, progress was slow — the traffic was less intense, and the pressure of freight traffic on the available facilities was greater. The capital cost was therefore heavier in comparison with the reward to be obtained. Still progress was being made, and new sections of suburban line had been electrified in the Liverpool area, and on Tyneside, within the last few weeks. Main line electrification stood on a different footing. It must justify itself as a business proposition mainly on the economies it brought with it; and unfortunately the smaller the scheme the smaller l was the proportion the economies were likely to bear to the capital expenditure involved. An experiment to be successful must be made on a big scale or not at all. Such an experiment was in progress on one of ,the lines connecting Manchester with Sheffield, where heavy grades, long tunnels and intensive traffic gave favourable conditions for success. Taking the whole of our railways, even those that served the North of Scotland, they gave a more frequent service than any other country in the world — more than twice as frequent as the French railways and eight times as frequent as the U.S.A. Passenger questions, continued Sir Ralph, bulked large in the public eye, but as a matter of fact the railway drew much less than one-half of their revenue from passenger business. Coal and goods traffic gave more money over all. They carried 190 million tons of coal a year out of about 240 million tons produced, but they carried it only 44 miles on an average; in America' they carried it 324 miles, and in India 200 miles. On the other hand, they were themselves one of the largest consumers of coal, and one wagon- load out of every fifteen that they hauled went to stoke the fires of their own locomotives.

The Castlecary accident. 199.
On 10 December 1937 the 16.03 Edinburgh to Glasgow express over-ran Castlecary home signal and hit stationary 14.00 Dundee to Glasgow train leading to 35 fatalities. Automatic Trtain Control would probably have prevented the accident. The Inspecting Officer commended the Buckeye couplers and Pullman vestibules on the coaches of the express.

London & North Eastern Railway. 199
New 0-6-0 tender-engines of the J39 class, completed at North Road Works, Darlington, were Nos. 1930, 1933, 1940, 1942, 1943, 1952, 1965 and 1971, all of which, we understand, were working in the Southern Area. An innovation in the tenders of the last four of these engines was the fitting of a high back piece, with a coal gate, similar to the tenders of the V2 class and the Pacifics. The first of the new series of K4 class in hand was No. 3442 Mac Cailein. Mor and was painted green. The latest A4 Pacific No. 4901 Capercaillie was working from Gateshead. 4-4-0 D49 class No. 327 had been rebuilt with Walschaerts valve gear.

The Flying Scotsman of 1888 and 1938: fifty years of speed. 200-5. 6 illustrations, diagram (elevation and plan)
Press demonstration run to introduce two new train sets for non-stop Flying Scotsman and Sunday Scotsman between London and Edinburgh, but limited to a run from Stevenage to Barkston Junction and back. From King's Cross to Stevenage travel was in six-wheel coaches hauled by Stirling single 4-2-2 No. 1. From Stevenage the new rolling stock was employed hauled by A4 No. 4498 Sir Nigel Gresley.. The trains featured a buffet car with a ladies' lounge and toilet room in addition to first and third class dining cars. Double glazing and sound deadening materials (rubber and asbestos) were employed to provide a quieter passenger environment. Pressure ventilation was provided. The exterior was the normal teak finish, but the interior was more like that of the streamlined trains.

Institution of Locomotive Engineers. Summer Meeting in Scotland. 206-8. 2 illustrations, table
The summer meeting took place on 8-12 June and included Dr Dorpmuller, the German Minister of Transport and fourteen officers of the German State Railway. The British Minister of Transport, Dr. E.L. Burgin was also present. Stanier was in attendance.
A special seven coach train, including the LMSR dynamometer car, hauled by Coronation class Pacific No. 6225 Duchess of Gloucester was run from Euston to Glasgow Central with a stop at Carlisle to change the engine crew which had been Driver F.C. Bishop and Fireman J. Greenup of Camden then Driver D. Kerr and Fireman T. Reid of Polmadie. The main interest was the rapid ascents of Shap and Beattock banks.
The Institution's Dinner was held in the evening of 9 June in the Grosvenor Restaurant, following a cruise to Inverary on the Duchess of Montrose. Both the Ministers of Transport spoke at the dinner. Dr Burgin called for simpler controls on the locomotive and Dr Dorpmuller noted that Britain relied for steam for her railways more than any other country..
A visit was made to the Clydebridge Steel Works of Colvilles Ltd in the morning of Friday 10 June and after lunch St. Rollox Works was visited where the preserved Jones' goods 4-6-0 and Caledonian Railway No. 123 were inspected. Saturday was spent at the Empire Exhibition and on Sunday morning the LNER arranged a special train from Queen Street to the Forth Bridge where the visitors were allowed to study part of it on foot. In the afternoon they were taken on a coach tour of Edinburgh.

[Lovett Eames]. 216
Re article in the December 1937 Issue, page 402, on the American single driver locomotive Lovett Eames, tried on thc Great Northern Ry. in 1881 and sold for scrap in April 1884, it was stated the engine bell was retrieved and preserved for many years at King's Cross Locomotive Depot. It was moved to Hornsey when the new shed was built and it served as a time signal for the filters employed there. Its active service accomplished it was on 11 July  handed over by Sir Nigel Gresley, on behalf of the L.N.E.R., to Mr. Richard Perinoyer , who is attached to the American Embassy. He has long wished to have a locomotive bell and is providing a good home for it.

A new speed indicator and recorder. 216. illustration
The provision of a reliable speed indicator and mileage recorder on the footplate of the locomotives working the present day high speed trains, is of increasing importance to enable the drivers to successfully handle them at the booked running times, as well as of assistance in regulating the speed over curves, junctions, etc., which carry a statutory limit. The record of the actual running serves as a support as well as a check in avoiding disputes about responsibility for delays. The Tel. R.T. 835 Speed Indicator and Recorder introduced by the Hasler Telegraph Works, London, for indicating the speed of locomotives, railcars and other vehicles, had been specially designed for flexible shaft drive.

The first two of the new series of Castle class locomotives are numbered and named 5068 Isambard Kingdom Brunel and 5069 Sir Daniel Gooch in memory of the two men famous in railway history throughout the world, and an appropriate commemoration of the centenary of the railway. Both locomotives were stationed at Old Oak Common Sheds. At the last annual meeting of the company the Rev. H. P. Hart drew attention to the fact that the Great Western Railway no longer had locomotives perpetuating the names of these famous engineers. In reply, the Chairman promised that this should have prompt consideration; apparently these remarks have soon borne fruit. I.K. Brunel was the company's first engineer. He planned and built the line from Paddington to Bristol; was champion of the broad gauge; builder of Box Tunnel and the famous Royal Albert Bridge, Saltash, Maidenhead Bridge and Clifton Suspension Bridge, and designer of the Great Western, the first steamship to provide a regular sailing across the Atlantic. Sir Daniel Gooch was the company's first locomotive superintendent, founder of Swindon \Vorks, designer of famous locomotives, and later Chairman of the Company. He was the champion of the Severn Tunnel scheme and laid the first Transatlantic cable, for which he was knighted.
New engines completed at Swindon during May were:- No. 7245, 2-8-2 tank; Nos. 4125-29, 2-6-2 tanks; Nos. 3770-74, 0-6-0 tanks. Withdrawals during the same period included Nos. 2375, 2394, 2421 and 2450, 0-6-0 tender; No. 4244, 2-8-0 tank; Nos. 4319, 4342, 4360 and 4399, 2-6-0 tender; Nos. 5100 and 5145 2-6-2 tanks. Express engines were to be fitted with an improved safety glass of the Armour plate type in order to give better protection to enginemen.

The contract for earth works, retaining walls and bridge abutments in connection with widening the Metropolitan line to four tracks between Harrow and Rickmansworth had been placed with Sir Robert McAlplne and Sons Ltd. Electrification of the line beyond Rickrnansworth to Amersharn and Chesham was to be put in hand, and do away with the need for the exchange of electric and steam locomotives on London Transport trains at Rickrnansworth, and five or six minutes saved on the journey het ween Baker Street and outlying stations.

Since the day in 1874 when William Stroudley placed in service his first goods tank engine, No. 97 Honfleur, the El class has enjoyed a dual identity that makes its story the more interesting. Designed essentially for freight work, as, witness the 4 ft. 6 in. wheels, the class was split up at an early date, and a number of its engines were transferred to passenger duties. The transfer involved certain mechanical alterations and additions, among the latter air brakes and the electrical passenger communication, but its most striking external feature was the substitution of the resplendent yellow livery for the more sober "goods green" that had hitherto characterised the class.
This mixing of duties at so early a stage in the career of Stroudley's goods tanks has always been something of a mystery, upon which even the authors of the "Histories" have not thrown any light, but it now becomes possible, through the researches of J. Pelham Maitland, to clear up this old-age topic. At the period referred to—that is, the decade commencing with 1877—the districts of South London served by the Brighton Company were undergoing so rapid an expansion that Stroudley found himself unable to cope with the demands for engine power. Brighton Works was indeed turning out passenger tank engines of the D class as fast as it could, and presently Neilson's of Glasgow were also called in to build numbers of these badly- needed locomotives. Unfortunately, even Neilson's, harassed as they must have been by Stroudley, who always "wanted his way to the last bolt and nut," were unable to work miracles in the way of immediate delivery, and in the interim of waiting, Stroudley had to find some other means of satisfying the Company's patrons. Particularly difficult was the case of the main suburban line out of London Bridge, owing to the stiffness of the New Cross bank. The increasing weight and frequency of the trains over this section were sorely taxing the abilities of the older suburban engines and the existing D tanks were needed in many other places as well. It was necessary to temporise, and this Stroudley did in the only manner open to him, by allocating some of his goods tanks to these arduous turns, which apart from their importance in the scheme of things, had the additional merit of dealing with first class and sometimes cantankerous passengers, who brooked no delays or breakdowns whatsoever.

The boiler carried a working pressure of 172 psi. The heating surface was: tubes and flues, 1,490 ft2.:firebox, 119 ft2.; superheater, 380.5 ft2; combined total, 1989.5 ft2 The grate area 32.29 ft2. The 5,000 gallon tender had a fuel space of 317 ft3 The adhesive weight was 46.5 tonnes and the total engine weight in working order is 72 tons

Electric colour light signals. 231
Installed on the L.N.E.R. line between Wickford and Southend and brought into use on Sunday, 26 June. The semaphore signals have been dispensed with and all trains over the 12½ mile section of line will be controlled day and night by 38 red, yellow and green searchlight signals, many of which will be worked automatically by the trains themselves. The new signalling was expected to be of great assistance during foggy weather.

The fourth of the new streamlined Princess Coronation class locomotives, No. 6228 Duchess of Rut/and was in service, thus leaving only one other to complete the series of five with streamlining. This engine, No. 6229 Duchess of Hamilton, nearing completion at Crewe, had been selected for  American tour, and very probably would be finished in the blue livery which was specially chosen for the Coronation series, Nos. 6220-4. Two of the non-streamlined engines. had also been turned out at Crewe, Nos. 6230 Duchess of Buccleuch and 6231 Duchess of Atholl. Patriot class No. 5503 The Leicestershire Regiment and No. 5516 The Bedfordshire and Hertfordshire Regiment had been named. Engines rebuilt with standard Belpaire boilers included G1' class Nos. 9008 and 9113; also 18 in. goods class No. 8526. . One of the latter class, No. 8532, was running fitted with a round top boiler. Recent withdrawals included the following: 0-6-4 tank No. 2032; 0-6-2 coal tanks Nos. 7688 and' 27593; 4-6-2 superheater tank No. 6956; and 0-4-2 shunter No. 7859. Two of the new series 2-6-4 passenger tanks building at Derby were in service, Nos. 2618-19.

Correspondence. 231

[Life of Dugald Drurnmond]. W.B. Thompson.
Re life of Dugald Drurnmond stated that his 4-4-0 engines on the North British line had a pressure of 140 lb. This figure should be 150 llb. I used to see the engines on the Waverley trains fifty to. sixty years ago, and always understood that their pressure was 150 lb. The article in The Engineer 4 January 1878, which described the engines merely said that they were tested for 150 lb. in steam before g'oing into service, but the earlier article dealing with the goods engines, which except for the wheel arrangement were practically the same engine as the 4-4-0s, said that "the working pressure of Drummond's engines is 150 lb." (see The Engineer, 5 January 1877). It must be remembered that the Brighton Grosvenor, with which Drummond had been closely associated, had a pressure of 150 lb., and it was natural that Drurnmorrd should use it in his own engines. When new the Waverley 4-4-0's were easily the finest engines in the kingdom; the engines of the other six companies serving Carlisle looked a very poor lot beside them. The double-singles, the "720" class, on the L.S.W. were- apparently a European edition of the James Toleman, of the Chicago Exhibition in 1893. Unfortunately they were much too small for the traffic at the time when they were built, but with light trains they could run well. If they had been on a larger scale they might have given a good account of themselves.

A greater part of the heat of the boiler water ought to be transmitted to the filling water and can be achieved: (1) Steam and water may be discharged separately. (2) Boiler water may be blown-down by steam pressure (without recovering the steam separately). If the heat is being transmitted according to the first method it is obtainable: (a) By means of leading the boiler water through the filling water, to which the steam blown-down for the direct heating of the freshly supplied clear water is admitted; (b) By means of leading the fresh water, before its entrance into the filling tank, through the blown-down boiler water; (c) By means of leading the boiler water through a heat exchanger through which flows simultaneously the supplied fresh filling water. If the blowing-down of the boiler water is performed with steam pressure (according to the second method) the boiler water should be conducted: (a) Through a heat exchanger, to which the fresh filling water is supplied in a quan-tity dependent on the desired final temperature of the fresh water ; (b) Through the filling tank constructed as a preheater and containing at least the water quantity necessary for one filling.

World Power Conference. Vienna Sectional Meeting. 284
A paper on The Requirements and Supply of Energy for Electric Railways, was presented by Francis Lydall, from Merz and McLellan, at the 1938 Sectional Meeting of the World Power Conference in Vienna on 25 August 1938. Lydall divided his subject into four parts: the first discussed the energy requirements for electric traction, and showed that these are much lower than is usually expected, an approximate figure being 50 k.w.h. per 1,000 ton miles. Train heating during the winter adds about 10% to this, and reference was made to the relative advantages of steam and electric heating. The second section dealt with the consumption of energy for railway traction in Great Britain, which in 1937 amounted to 1,352,793,000 k.w.h. A table showed the consumption of various electrified lines for that year, with the source of supply and the half-hourly maximum demand. The third part of the paper related to the fluctuations of traction load and the ratio of the average to the maximum demand, and the author gave some interesting instances of the variations due to conditions of service. Curves were given showing the output from the power stations of the London Passenger Transport Board during a typical winter and summer week-day, also on a day of exceptionally heavy traffic. In the fourth section the factors affecting the cost of energy for electric traction were examined, and the relative advantages of purchasing energy and private generation were considered. Details of the provision of power for its electrified services were given by permission of the Southern Railway, which derives its current partly from its own power station built before 1914, partly from a power company, and partly from the Central Electricity Board, and the significance of the figures was explained.

North Road Works, Darlington, had completed series of J39 0-6-0 goods engines, the last six being Nos. 1974, 1977, 1980, 1984, 1996 and 1997, and these were located to the Southern Area. The first two of the new series of V2 2-6-2 tender engines Nos. 4804 and 4805 were completed. No. 4804 differed from the earlier engines of this class in having a multiple-valve regulator fitted in the superheater header and the regulator rod was outside the boiler, with a compensating crank about half way. One of the new engines is to be named The Green Howard, the christening ceremony taking place at Richmond at the end of the month. New 2-6-2 tanks of the V1 class completed at Doncaster were Nos. 404 and 425. The first of Jas.

The Brunels, father and son. Celia Brunel Noble. London: Cobden-Sanderson.
Lives of the famous engineers who form the subject of this work have already been written, but the authoress, who is a grand-daughter of the younger Brunei, now gives us a picture of them from the home and personal, rather than the engineering, point of view. It is perhaps not always remembered that the Brunels were descended from a very old French iamily which ·is now extinct. Circumstances connected with the French Revolution caused the elder BruneI to seek a new home and, after various vicissitudes, he ultimately settled in this country where his genius and inventiveness soon made a name for himself. With the British public he is generally associated with the Thames Tunnel and his son with the Great Western Railway, but these, after all, only represent a portion of their lives' work, It would be tedious to enumerate everything with which they were engaged but in all they displayed an enthusiasm, originality and ingenuity which, however, was not always combined with business acumen. It is no doubt difficult in these days, with the result of years of experience to assist us, to fairly apportion praise or blame to the works of these pioneers. The Thames Tunnel is hardly thought of to-day, and the many innovations which the younger BruneI introduced on the Great Western Rly. have nearly all been relegated to a forgotten past. At the same time they will always be remembered for the daring they displayed, both in the conception and in the execution of the works they undertook and such an authoritative and carefully compiled record of their daily lives as the authoress has now given us will be welcome by all interested in the achieve- ments of the early pioneers.

Quartet in steel.The complete book of British Railways. Horace Greenleaf and Howard Hayden. Frederick Muller, Ltd. 300
Railways have been for many years popular themes for juvenile books. Generally speaking, they have been confined to two classes. There is the highly coloured picture book for the very young, and the diagram-studded, technically-worded manual for the youthful student of railways. The growth, working, and achievements of Britain's four great companies is a fascinating story; yet comparatively few writers have attempted to relate it. This story has now been told by Horace Greenleaf and Howard Hayden in simple, straight- forward terms. Together they have penned Quartet in Steel, a book which bridges the gap between the elementary and the technical. The volume presents an intimate picture of railway working. It traces the progress of the British lines from the small horse-drawn affairs of 150 years ago to the steel highways of to-day; outlines the ramifications of the modern companies; and explains the working of a locomotive, the meaning of signals, the history of the Pullman car, and the reason for electrification projects. The reader travels with the driver and fireman on an express engine; watches the chef and stewards at work on a dining car; peeps inside the famous travelling post office, walks along "the track"; and follows in the wake of a flier on its journey across England. "Quartette in Steel" is interesting and informative reading, lavishly illustrated with more than fifty photographs. Originally the book was planned for use in schools, but the publishers. realising its general appeal decided that it should also be available to the public, and have therefore produced an attractive addition at the popular price of six shillings. Mr. Greenleaf is on the staff of the Southern Railway Advertising Department, and is an experienced writer on railway and similar topics. Mr. Hayden, a well-known educationalist, is the author of several school books, and is a specialist on children's plays and books.

A survey of railway development and practice.  P.E. Garbutt. London: Arthur H. Stockwell Ltd.
This comprehensive survey of the railways throughout the world gives the general principles governing their administration as well as the economies of rail transport. After tracing the 'history of the origin and organisation of the railways of [his country, the author refers to the complicated question of railway rates firstly as a means of increasing traffic and the development of industries, and secondly the transport of such traffic as cheaply and efficiently as possible. Financial progress is then discussed. Following chapters are devoted to sketches of railway development on the Continent of Europe, in America and Asia, Australia and Africa, explaining the administrations and organisation in each case. A further section includes reasons for electrifying railways and for diesel-electric traction and their advantages in special cases. Attention is also drawn to questions of road transport competition. The student of railway economics will find this book useful in giving a concise view of the present day position and of the many problems facing the railways.

L.N.E.R.-locomotive depots. 300
To bring locomotive depots up to the latest standards, the L.N.E.R. had recently let several contracts for improvements at certain principal depots. At Lincoln where the depot was being completely transformed— the last stages of the work were now in hand and W. Wright & Son (Lincoln) Ltd. had been awarded the contract, valued at £2,000, for the extension of the general stores in which spare locomotive parts and materials such as lamp oils, sponge cloths, etc., were kept. At Darnall, near Sheffield, the L.N.E.R. is constructing a new locomotive depot in connection with the Manchester-Sheffield electrification scheme and this depot would provide accommodation for both steam and electric locomotives when completed. Longden & Son of Sheffield had been given the contract for the construction of locomotive inspection pits here and work would commence almost immediately as it is very desirable that this depot should be ready for the change-over from steam to electric working when that time comes, planned for two years hence. The same firm had also been awarded a contract for building dormitories at this new locomotive depot which will be available for enginemen who have to spend a night away from home. The value of these contracts is £30,000. At Darlington where the locomotive depot is being modernised a contract for rebuilding the locomotive sheds has been let to Haymills Ltd. of London. This locomotive depot, which has associations with the earliest railways, will, when complete, be one of the most up-to-date. A mechanical coaling plant, new engine disposal pits, up-to-date repairing equipment together with new offices and a new mess-room are all included in this modernisation scheme, and the turntable is to be replaced by one of 70 ft , diameter to deal with the larger engines in use.

Exeter St. David's station.  300
The first instalment of the Great Western Railway Company's scheme of improvements at Exeter announced. This provides for the remodelling of the station building on the "down" side, widening of the building on the station approach side by 11 feet for a distance of 170 feet, erection of canopy covering for cars, 350 feet in length, running along the whole front of the building. The present architectural features of the station will be retained, aud the new work will be faced with stone to match. The work will be done in two stages, the first of which will commence in the autumn. Prior to this, temporary booking office and waiting roorns will be constructed on the open space in front of the station, and temporary cloak rooms near the Divisional Superintendent's Office. The first stage will consist of remodelling the building at the London end of the station and erection of the new addition. When completed this will provide a wide station entrance, large booking office, public enquiry office, lugga-ge hall and spacious refreshment and dining rooms with kitchens planned on up- to-date lines. The first floor will accommodate the Divisional Offices. Improvements will also be carried out to the station approach and the open space in front of the buildings.

Feedwater treatment . 335
The effects of bad feedwater on locomotives are certain and may be resolved into priming or foaming, and deterioration due to deposition of scale possibly accompanied by acidity of the water within the boiler, the first being an immediate result and the second a slow but none the less sure process. Water for locomotive purposes is derived from three general sources; rivers and springs; wells and boreholes; surface supplies, such as collected rainfall. Surface and river supplies are particularly liable to organic contamination from earthy or vegetable matter held in suspension but that from wells or boreholes, especially of considerable depth, will yield water of a considerable degree of organic purity but unfortunately often rich in scale-forming compounds, of which the more common are the carbonates of magnesium and calcium and the chlorides or sulphides of sodium, magnesium and calcium. It may be remarked that rivers and surface-waters collected from peaty country are generally soft and particularly suitable for locomotive purposes; rivers from other sources vary in hardness, the River Thames at Hampton Court for example, averaging about 15 degrees on Clark's scale. Definite traces of sulphuric acid have been found in rainwater collected in urban areas; a very undesirable constituent of any feed water. As a further example, certain waters in East Africa contain sufficient magnesium salts to give them a distinct medicinal value and these in connection with the other salts present were sufficient to cause such priming that drivers found it necessary to use their blow-down cocks very heavily in order to get over the line; delays due to blowing-down and priming were frequent and failures due to broken piston-heads and cylinder-covers by no means unknown prior to the institution of a treating plant. The major reason in such a case for treatment would be the elimination of priming; the cleanliness of boilers being an obviously ancilliary advantage. Here we would make a digression respecting the definition of the terms "foaming" and "priming", which seem to be rather loosely used at times. We would define "priming" as the visible or tangible emission of water from the chimney and "foaming" as an intensely disturbed state of the water-level in the boiler unaccompanied by the emission of water from the chimney. We are of course aware that priming in a non-superheated engine can be converted under these definitions to foaming in a superheater on account of the carried-over water being evaporated in the superheater elements but we think that in spite of this the definitions are sound. Organic impurities are removable by filtration through sand, but the inorganic compounds require chemical treatment specially designed to deal with the particular salts present. It is an unfortunate feature of locomotive operation that a lime-soda softened water as well as an heavily impregnated water will cause priming; an example of the latter has already been referred to and it is well-known that the L.M.S. Railway are experimenting with a system of continuous blow-down with a view of eliminating the trouble due to the former. We ourselves have information from Australia that a residual hardness of 4 degrees after treatment has been found to give all-round satisfaction and it may be that a compromise on this basis may offer the best solution. The hardness before treatment of the Australian water was 16 degrees ; other railwavs however find this residual hardness unnecessary. At the same time it seems wrong to dogmatise too much on this aspect as the design of the boiler itself must enter very largely into any calculations, some designs seeming to be singularly free from any tendency to priming. There is however no doubt about the pressing need for treatment of most of the water supplies available: higher pressures and intensified use are making heavy demands on a strictly limited unit and the old method of removing an inverted "V" of tubes after a mileage of 18,000-20,000 miles for the removal of the accumulated scale is both expensive as well as wasteful of power. It is difficult to follow the argument used by some locomotive engineers that "hot-washing-out" is a satisfactory substitute for chemical treatment as each process serves a distinct purpose; the combination of the two however show a very considerable increase in the mileage between that bugbear of all running-sheds, washing out the boiler.

Written as a companion article to the same author's "Vancouver to Calgary on the footplate" (Loco. Rly Carr. Wagon Rev., 1938, 44, 244-8). On the first day he experienced a short jouney from Top Shed down to King's Cross on Stirling 8-foot single No. 1 where he was struck by the austere simplicity of the cab and the gentle slipping of the drivin wheels. On the following couple of days he was treated to travel on the cab (and in the train) on the non-stop Flying Scotsman hauled by No. 4491 Commonwealth of Australia where he was impressed by the  Flaman speed recorder, the bucket seats, the vacuum mechanism for locing the reversing gear, the V-shaped cab front, the chime whistle (a vast improvement upon the shrill whistle). The train was crewed in both directions by Driver Taylor and Fireman Floyd of Kings Cross and Driver Maguire and Fireman Kinnear of Haymarket. The baby son and wife of the last-named travelled on the northbound journey. He comments on the three-cylinder smoothness, the easy firing; the aalmost routine use of 15% cut off even on the ascent to Stoke, the slowing for water pick up and the perfect time keeping. The road was more difficult north of Newcastle. The maximum speed was 85 mile/hour down from Stoke. The firedoor tended to be left open.

Centenary of the North Union Railway. 348
The North Union Railway opened between Wigan and Preston on  21 October 1838. Thie company had at least one claim to distinction in that it was created by the first railway amalgamation, between the Wigan Branch Railway and the Preston and Wigan Railway. The locomotive stock in 1838 consisted of eight engines, designed by Edward Bury. Of these, Nos. 1, 8 and 9 were constructed by the Haigh Foundry Co., Nos. 2 and 3 bv Jones, Turner and Evans, while Nos. 4, 5 and 6 were products of Benjamin Hick and Co. All these engines had cylinders 12 in. by 18 in. except No.. 1, constructed the previous year, in which the cylinders were 11 in. by 16 in. This engine also had driving wheels 4 ft. 6 in. diameter. and carrying wheels 3 ft. 6 in. diameter, these dimension. in the case of the remaining engines being 5 ft. 6 in. and 4 ft. 6 in. respectively. No. 7 was constructed the following year, the makers and dimensions being similar to Nos. 4, 5 and 6

Chicago, Milwaukee, St. Paul & Pacific R.R. 346
The American Locomotive Company had constructed six 4-6-4 streamlined express passenger locomotives for the above system. These engines had cylinders 23½ in. diameter by 30 in. stroke; driving wheels 7 ft. 0 in. diameter; the boiler. which has a total heating surface of 5861 ft2., pressed to 300 lb. psi. At 85 per cent. b.p. the tractive effort was 50,300 lb.; the weight of the engine in working order was 185 tons. The tender carried 20.000 gallons of water and 25 tons of coal, the \veight loaded being 167 tons

In association with the opening of the line from Evercreech Junction to Bath powerful 0-6-0 were bought from John Fowler & Co. of Leeds: they had a strong similiraity with Stirling Great Northern designs  and in the case of the first four even had domeless boilers (Fig. 16: photograph of No. 20 in this form). They were WN 2125-30: they had 4ft 6in wheels; 17½ x 24in cylinders; 1084ft2 total heating surface; 15.8ft2 and 140 psi boiler pressure. The main frames were unusually thick (1¼in) and were of sandwich construction. They were fitted with brakes. Theey were reboilered from 1888. They lacked balance weights. They were reboilered again between 1908 and 1911: 1176ft2 total heating surface; 16.2ft2 grate area and 160 psi boiler pressure

The ex-L.N.W. class G1 0-8-0s (Schmidt superheater) were being gradually converted from 160 lb. to 175 lb. pressure and assimilated to class G2; but as a sub-division of the latter are designated G2A. For traffic purposes the power classification is also raised to that of the G2's, viz., 7F. Two further three-cylinder 4-6-0s of the Patriot series had been named as follows: No. 5514 Holyhead, and No. 5538 Giggleswick. Withdrawals included the following ex-L.N.W. engines :-Prince of Wales class 4-6-0 No. 25656; 4-4-2 (Precursor) tank No. 6803; 0-6-0 tank No. 27356; and 0-6-2 tank No. 27660. The series of 2-6-4 passenger tank engines buitding at Derby in connection with the 1938 programme will be followed by a series of ten 0-6-0 standard freight engines (Class 4). The latest 2-6-4 tank in service is No. 2637, and of recent ones Nos. 2631-34 have been allocated to the Central Division.

Period 1870 to 1918. From 1869 to 1872 the Galician Karl Ludwig's Bahn acquired several Hall type 2-40 and 2-8-8 tender engines. This probably explains the citation to this from Locomotive Mag., 1950, 56, 182 which attributes this article to L. Derens. An 0-4-2 for working faast passenger trains was introduced in 1872: these had 15½ x 25in cylinders; 74½in coupled wheels; 1075ft2 total heating surface; 16ft2 grate area and 115 psi boiler pressure. WN 1196-99 were built by Esslingen in 1872 and WN 1245-52 in 1873. The Austrian North Western Railway acquuired 46 4-4-0 from Wiener Neustadt and Florisdorf between 1870 and 1873. These had 16 x 25in cylinders; 62in coupled wheels; 1360ft2 total heating surface; 18¼ft2 grate area and 140 psi boiler pressure. Two 4-4-0 were built by SIGL for the Viennna Exhibition of 1873: Rittingen went to the Austrian North Western Railway and the other to the Sudbahn. There was then a move away from the Hall type. Seventy inside frame outside-cylinder 4-4-0 wer built for the Kronprinz Rodolfbahn, Westbahn and STEG. They had 17¼ x 25in cylinders; outside Stephenson valve gear; 67½in coupled wheels and 18 psi boiler pressure. Eight 2-2-2 were supplied to the KFNB: four from Strousberg in 1871.and four from Florisdorf  in 1873.  Powerful 2-4-0 were supplied by STEG to the Westbahn i 1879-80. These had inside Allan link motion; 17 x 25in cylinders and 74½in coupled wheels. They worked the Orient Express. In 1880 the Haswell Works supplied the KFNB with light 2-4-0 of the Crampton type. They had 15¾ x 25in outside cylinders and 69½in coupled wheels

Institution of Locomotive Engineers. The fatigue strength of machined tyre steels. 362-3
At meeting held on 26 October T. Baldwin, Associate Member, read his paper (394) on the above subject, of which the following is an abstract. A large proportion of the breakages of locomotive parts in service are due to fatigue. On examination such fractures are seen to have occurred at "fatigue flaws," which slowly grow into the sound metal until the latter suddenly breaks in a very brittle manner. These service fractures, with a complete absence of plastic distortion, are very different from the fractures obtained in a tensile testing machine. The latter type show no signs of a smooth growing flaw and the test piece is seen to have altered its shape considerably during the test.
The author then proceeded to deal with the fatigue characteristics of metals, explaining the relationship of tensile strength and ductility, and also the effect on the fatigue strength of mean stress and cold-working.
Referring to the effect of stress concentration on fatigue strength, he pointed out that a calculated reduction of 77 per cent. caused an actual reduction of only 62 per cent. for a hard steel and 34 per cent. for a soft steel. The point that one would like to emphasize is that although mild steel does not suffer so great a percentage reduction of fatigue strength as hard steel through stress concentration under reversed stresses (with zero mean stress), it never seems able, under these conditions, to put up such a good performance as the hard steel on test pieces of the same dimensions. This is irrespective of the degree of stress concentration, provided that it is the same for both steels.
Materials like cast iron have only a low fatigue strength, as the graphite flakes give rise to stress concentration. Such materials are, therefore, comparatively insensitive to additional stress concentration due to notches and irregularities of shape.
A soft steel may give a better performance than a hard steel under conditions of high mean stress in the presence of surface irregularities, as a soft steel can yield until the steady stress is relatively unimportant. The fatigue range of the soft steel may then 'be higher than that of a hard steel, which will not yield and which consequently has its fatigue range reduced by the presence of a high mean stress.
At a tyre bore there is considerable stress, due, amongst other things, to the shrinkage stress, the axle load, impact bending stresses, and also, to high local pressure from the wheel centre.
Fatigue is largely connected with high values of shear stress. Now the maximum shear stress is equal to half the difference between principal stresses at right angles to one another, and consequently a high local compressive stress, which is reckoned negative, increases the shearing stress if the other principal stress is a tensile stress due to bending and shrinkage. Further, the bore may be more or less roughly machined, which gives rise to cracks and stress concentration, and the machining also has the effect of cold working the surface so that the diamond pyramid hardness number is raised from about 270 to 320.
The fracture of tyres in service is a matter which is naturally regarded seriously by locomotive engineers. Apparently tyre breakages have been more frequent on some railways than on others, and the Company with which the author is connected has been anxious to do everything possible to prevent failures of this nature. It was not proposed to include the general question of tyre failures and tyre stresses within the ambit of this paper, but rather to concentrate attention upon one particular feature of the subject, that of the effect of machining on the strength of the steel.
Most tyre fractures show a small fatigue flaw spreading into the tyre from the machined surface of the bore close to the flange face. As there was very little information available about the fatigue strength of tyre steels in the condition in which they are put in service, it was decided (in March 1932) that an attempt should be made to determine the fatigue strength of specimens taken from the actual bores of tyres.
Proceeding to the matter of testing, it was explained that most published work has been confined to cases where the direction of machining was at right angles to the direction of stress. Machining usually gives rise to a number of transverse cracks across the bottom of the grooves or furrows made in the surface, and, since the direction of machining in a tyre bore is parallel to the probable direction of (bending) stress, it: was thought advisable to reproduce this state of affairs in the testing. The transverse cracks are then at right angles to the direction of stress.
The flaws in tyres develop in a direction which is initially more or less in a radial plane so the test was arranged to be a bending test with the tyre bore surface forming one surface of the test piece and the bending taking place in what is normally the plane of the wheel. It was also considered desirable that the bending moment should be constant over a reasonable length of the test piece and, furthermore, that a mean steady tensile stress should be present at the bore surface to imitate the shrinkage stress ordinarily present in a tyre. This stress was arbitrarily fixed at 9.0 tons per sq. in., a figure that might, perhaps, be considered slightly on the low side.
Experiments made with a Haigh fatigue testing machine on the fatigue strength of tyre bores were then described, together with the methods of testing and some difficulties which arose.
An interesting point was the effect on the fatigue strength produced by various finishes. These tests, which were made on a right driving tyre that had failed due to a fatigue flaw developing from the bore at a stud hole, showed that the bore in the service condition had a fatigue range of about 9 ± 13¾ tons per sq. in. This tyre had been rather roughly bored, having 17 cuts to the inch. Some further specimens were prepared by shaping, the bore surface of the tyre being removed in the process so that the finished surface at the centre of the specimens was 1/8 in. below the bore surface. Although the feed had been reduced to 50 cuts per inch the fatigue range was practically unaltered. Other specimens had the bore surface removed by draw filing, using a 12 in. flat bastard file of about 19 teeth per inch. This raised the fatigue range to just under 9 ± 18½ tons per sq. in. Grinding the bore on a pendulum-type link grinder gave a better result still, over 9 ± 19.0 tons per sq. in., although the number of specimens available was not sufficient to obtain a more exact result. The amount of metal removed from the surface by grinding varied from 0.030 in. to 0.033 in., measured from the crests of the machining marks. A number of specimens prepared similarly to the shaped test pieces were finished by filing and polishing with emery paper. The fatigue limit in this condition was about 9 ± 21¾ tons per sq. in., although it is curious to notice that the broken specimens, bot:h in this series and also in the ground series, failed by flaws developing from the compression side of the test piece. Apparently the polished surface ½ in. or 5/8 in. below the bore surface had a lower fatigue range in compression than the ground or polished surface close to the bore in tension. Probably with similar material and surfaces the two values should normally be about equal, but the usual falling hardness gradient from the bore surface inwards towards the centre of the cross-section was apparently reflected in a corresponding reduction in the fatigue range.
The fad that the tyre in service had a fatigue range over 36 per cent. less than the optimum provided some food for thought, and it was desirable to obtain some confirmation of this result. During the course of an investigation on another broken tyre it was observed that its companion at the other end of the axle, whilst unbroken, was badly pitted and corroded in parts of the bore, whilst other areas of the bore were in relatively good condition and free from corrosion. As a matter of interest tests were prepared from both regions. Those from the non-corroded parts, whilst rather erratic, had fatigue limits lying between 9± 13.0 and 9± 14.0 tons per sq. in., thus generally confirming the previous results, whilst the corroded surfaces gave the much poorer figure of 9 ± 9.8 tons per sq. in. This result emphasises the importance of presenting tyre bore corrosion. The practice of applying linseed oil before shrinking on the tyre appears to be helpful in this direction.
Further tests made at the instigation of W.A. Stanier produced very interesting results, it being found that the finish resulting from the use of oarbide tool steel gave greatly increased resistance to fatigue, an improvement of 54 per cent in the fatigue range being obtained. This is a close approach to that obtained from a polished finish. The use of a 77 tons per sq. in. tyre steel bored with carbide steel produced an increase in the fatigue strength of no less than 91 per cent., the figure of 9 ± 24.8 tons per sq. in. being obtained as against the usual figure of 9 ± 13 tons per sq.  in.
The author emphasised that these figures- should be considered only as fatigue test results. Tables of bending fatigue test results and an appendix giving additional particulars of tyres used for tests concluded this paper.

G.W.R. 363
With the introduction of a further twenty streamlined railcars, the aggregate mileage run by railcars on the G.W.R. will advance to nearly two millions a year. Some of the new cars will have a maximum speed of 70 miles an hour and will be capable of hauling an extra carriage or of carrying out light shunting work. Two sets of twin cars are to be used for services between Cardiff and Birmingham, the railcars at present running being moved elsewhere. These cars will be provided with buffet and toilets and will have accommodation for 104 passengers. The extensive improvements to be effected at Whitland, Pernbrokeshire include new station buildings, a new goods shed .and a modern locomotive depot. The existing engine shed was to be demolished and the new one will be on a site at the Haverfordwest end of the station. Here there will be improved coaling facilities and a 65 ft. turntable for turning the larger engines working there.

Reviews. 367

Railways to-day. J.W. Williamson, Oxford University Press.
So many text books have appeared during recent years on the subject of railways that it is not to be expected that there would be much more to be said on the subject, and indeed, the writer of the present volume does not claim to introduce new material. It is one of a series, the Pageant of Progress, and in 160 pages Mr. Williamson has condensed most of what the average reader would require to know to obtain a general insight into the construction and working of the railway system. Beginning with a historical summary, the writer deals next with the route, gauges, tunnels, bridges and the permanent way generally. Then follow the building and repairing of locomotives and other rolling stock, with chapters on signalling and operating conditions. He concludes with a brief account of locomotives on the road, together with Diesel and electric working. Criticism may be directed against some of the statements in the historocal chapters, always a controversial subject, but on the whole the book depicts a fair and reasonable picture of the development and working of railways from the early beginnings to the present. In addition to a number of small line drawings, it is illustrated with 23 half tone plates, the reproduction of which is excellent.

Heat Engines. A.C. Walshaw, Longmans, Green & Co. 413 pp.
Intended as an introductory text-book, this is divided into three sections, dealing respectively with the essential principles of heat and heat engines, steam and steam plant, and thermo-dynamic and internal combustion engines. Generally this work is very complete and deals as fully with the subject as would appear to be possible within similar confines. It is up-to-date and owell illustrated.with diagrams and figures. In view of the extent to which the poppet valve is used in heat engines of to-day, it is rather surprising that it is not included in the, chapter on valves and valve gears. An even more inexplicable omission is the absence of a diagram or description of a locomotive type boiler. As this is one of the most rapid steam generators ever produced within the limits of its size and is also used for various stationary and small marine purposes, this is probably an over-sight. This book is undoubtedly a very useful contribution to text-books in its class and should be of considerable assist-ance to students preparing for examinations in the subject, or to those requiring a cortege work of reference.

Correspondence. 367

Edward Fletcher. W.B. Thompson
Re article on Edward Fletcher, locomotive superintendent of the North Eastern Railway from 1854 to 1883, does not mention a rather puzzling matter which attracted some attention at the time, namely, the frequency with which his engines suffered from boiler explosions. It was not only with old and worn out engines, or engines of obsolete type, that explosions occurred. Your article rightly described the double framed goods engines built in 1870 as excellent, but two of them were wrecked by explosion after a few years' service; and of the inside framed type introduced in 1872—a very fine engine for that date—No. 787 built by Stephenson and No. 941 built by Neilson exploded when still comparatively new. The North Eastern was of course not the only company which had boiler explosions, but the Board of Trade inspector in one case reported that in a named period there had been fifteen boiler explosions on British railways all put together, and that of the fifteen nine had occurred on Fletcher engines. The following for one period of fourteen months shows the position pretty clearly:
Engine No. 787 exploded at Blaydon, Nov. 24, 1878.
Engine No. 375 exploded at Headingley, Aug. 16, 1879.
Engine No. 737 exploded at Leamside, Sept. 9, 1879.
Engine No. 746 exploded at Silksworth, Jan. 26, 1880.
And so on.
What exactly was wrong with the design or maintenance of the Fletcher boilers I do not know, but they seem to have been very susceptible to grooving. Apart from this unpleasant failing the Fletcher engines were very good, and if they had run into London instead of being visible only in their own district they would have been much more famous. Perhaps the greatest distinction between locomotive practice in the early days of railways and at the present time. lies in the fact that in spite of much higher pressures and very large boilers—expecially in America—explosions to-day; are almost unknown.

"Atlantic" Locomotive, Dutch State Railway. W. Lubsen
Re Derens' serial article describing the bad riding of the Atlantic class. Considering the construction of the leading bogie of the engine, it must be said that this form cannot have the good running qualities known of other classes of the said wheel arrangement. Tne design of the bogie makes the engine in question resemble an engine of the 2-4-2 arrangement with leading pony-truck. The bad running qualities of this class are well known, due to the short fixed wheelbase compared with the whole length of the locomotive. When running at high speeds suoh an engine has a distinct tendency to rolling. The. high percentage of counterbalancing might have enhanced the unsteadiness of the locomotive. The fact that the converted engine now running as a resistance car does not show greater unsteadiness when running backwards at a speed of 100 km. per hour, does not allow the conclusion that if the engine had the 2-4-4 arrangement it would have been a better running locomotive. On this point I cannot agree with Mr. Derens, for the running. qualities of a railway vehicle may be very different when, self-driven or being drawn.

Early Austrian locomotive. L. Derens. 368
Re some peculiarities of the Hall arrangement as applied to the eight coupled engine for the Brenner Railway, described on page 285 of the September issue. The outside frames (without inside frames) were an essential feature of the Hall arrangement and were mostly of the sandwich type. Hall was an Englishman, and from 1852 works manager at the Maffei Locomotive Works in Munich. The absence of inside frames permitted a ten per cent. wider grate to be fitted, which in view of the inferior quality of fuel available in Bavaria and Austria was of much importanoe.
The most remarkable feature of the Hall arrangement was the so-called "journal crank." With this type the boss of the crank instead of being outside the journal box as usual, formed the bearing itself. This can be clearly seen on the half plan view of the 0-8-0 engine on page 285. This arrangement had the advantage of bringing the crankwebs close up to the journal box and .thus permitted the centre line of the cylinders to be much nearer the frames. This had the double advantage of enabling a stronger connection for the cylinders to be made and also greatly reducing the momentum of the piston force and the nosing movement of the engine resulting from this.
This reduction of the momentum was effected in two ways, for not only were the crankwebs much nearer the journal box, but owing to the large diameter of the crank boss, the length of the journal could be greatly reduced for the required hearing surface. The cranks were forged ,in one piece with the crank pins, which was a difficult job, and owing to the sudden changes in section of the material and sharp bends led to breakage in many cases.
Nevertheless, the other advantages of the Hall arrangement through this type of crank were so important that no less than 257 engines have been built with Hall cranks for South Germany, Switzerland and Austria.
Hall .first introduced his patents in Munich, and when afterwards he removed his aotivities to Austria, his system found much favour there.

Kofler ttain control on the Polish State Railways. 391. illustration
PoJish State Railways had equipped a section of Iine between Tlusz and Ostrolenka, a distance of about 46 miles, with the Kofler automatic train control system. This device is mainly mechanical, consisting of a tnip arm mounted on a support braced to the track adjacent to the signal which, when the signal is on, comes into contact with a trip on the cab roof of the locomotive and, pressing against it, actuates the brake-control equipment, red and green lights, hooter, etc.
When the track trip arm has acted on the locomotive mechanism, it .is automatically disengaged from its actuating 'Spindle and moves up clear of the loading gaug'e, so as to be out of the way of anything on the train that might be Iiable to foul it, and is restored to position for the next signal operation. Recent improvements include addi- tional electric apparatus consisting of a set of re- lays, a contact operated by the cab roof gear, red and green signal lights, hooter, resetting key, electrically controlled brake valve, and contact on driver's brake valve. Normally the green signal light shows and the A.T.C. brake valve is held closed; but if the trip arm on the signal actuates the cab gear, the green light is extinguished, the red switched on and the hooter begins to sound. If the driver observes the warning and manipulates his brake valve handle, a contact on the latter is made causing all parts to return to normal. If he does not do so, a slow-acting relay causes a partial opening of the A.T.C. brake valve, resulting in a slight brake application and, if the driver takes no action, a full application follows shortly afterwards. Operation of his brake valve will restore the paparatus and allow the driver to release the brakes.

During 1939 it was.intended to limit the locomotive building programme to engines of one type, viz. 2-6-2 V2. There will be 50 tender engines for fast goods and passenger trains and ten tank engines (2-6-2T "V") for local passenger services .in Scotland and on the North Eastern section. Owing to the serious drop in traffic and the need for economy a number of trains had 'been withdrawn. Most of them were on branch line services, but certain expresses between London and Norwich, Nottingham and Sheffield, Sheffield and Manchester, and Leicester and Nottingham had been cancelled.

London, Midland and Scottish Railway:. London and Birmingham Railway Centenary Banquet, Grosvenc House, London. 401
H.R.H. The Duke of Gioucester was the principal guest at a banquet presided over by Lord Stamp, to commemorate the centenary of the London and Birmingham Railway, There were over 800 guests preent.
Following the loyal toasts, the Duke of Gloucester proposed the toast of the London, Midland and Scottish Railway, and in a pleasing manner referred to the fascinating subjeot of early railway development. He mentioned a number of the extraordinary objections which arose from most unexpected quarters when railways were proposed, and recalled interesting events of the past, such as Queen Victoria's first journey by the Great Western Railway to Slough in 1842, also her two day journey from Balmoral to London in 1848, during which she stayed the night at Crewe. This journey, it may be remembered, was made unexpectedly owing to sea fog rendering dangerous a return by the royal yacht. The Duke also paid tribute to Lord Stamp and the traditions which have inspired the rise of the L.M.S.R. system to its present position of being the longest British railway.
Lord Stamp, in reply, expressed his gratitude to His Royal Highness for attending and graciously proposing the toast, remarking on the fact that this was the Duke's first public appearance after returning from his travels. He referred to rhe ocoasion as being not without its critics, and he felt that the directors would be failing in their duty if they passed by such a commemoration in silence. The Stockton and Darlington Centenary was indeed a distinct and distinguished event. The l..M.S. actual beginning was the Liverpool and Manchester Railway, and its hundredth anniversary had been adequately celebrated some years ago: Lord Stamp stressed the remarkable and not diminishing appeal which the railway exerts on the lay public, which had been emphasized by the response to the Centenary exhibitions at Euston and Birmingham. He also expressed pleasure at the presence of Dr. Dorpmuller of the German State Railway, whose visit complemented Lord Stamp's to the German Railway Centenary celebrations at Nuremberg, two years before. He recalled how in 1838 the Prussian Government had written to the London and Birmingham directors asking them for instruction in running a railway system.
"Old Euston " was the title of a beautifully produced volume which was afterwards passed round among the guests as a souvenir of the occasion. It had been specially prepared by Mr. Royde Smith, the Assistant Secretnry and a well-known 'railway historian. The builders of the original Euston struck a commemorative medal 100 years ago, and the L.M.S.R. had now followed their example 'by issuing a similar token, the first speoimen of which was presented to His Royal Highness.
Many of the guests formed historic links wioh the early days of railways. Alderman G.A. Solly of Birkenhead and Dr. Ernest Solly of Harrogate are great grandsons of Isaac Solly, the first Chairman of the London and Birmingham. Mr. S.R. Beale's uncle was Secretary of the Liverpool and Manchester. Sir Ralph Glyn's grandfather. George Carr Glyn, afterwards Lord Wolventon, was chairman of the Board 100 years ago.
The toast of "The Guests" was proposed by Mr. E. B. Fielden, Deputy Chairman of the L.M.S.R., supported by Mr. S. R. Beale.
The Minister of Transport, the Rt. Hon. Leslie Burgi)l, and the President of the British Iron and Steel Federation, the Rt. Hon. Lord Greenwood, responded.
Dr. Burgin, amid laughter, remarked that it excited him to learn that the L.M.S. possessed a capital of £460,000,000_ "Give me that," he said, "and I will put the whole of the Bressey Report into execution at once!"

A famous railway crossing.  401. illustration
Manganese Steel has for many years been recognised as the- ideal material for those parts of the track that are subject to unusually severe wear and tear—this includes, of course, points, crossings and sharp curves. Without question, .u steel of this character has become more than ever necessary in recent years in order to keep abreast of the more onerous working conditions met with on main line railways. It is, therefore, opportune to refer to one very important layout that has recently been supplied by the well known. Sheffield firm of Hadfields Ltd., and made entirely of Patent "ERA" Manganese Steel.
The accompanying illustration conveys a good idea of the complicated nature and magnitude of the job and as many of the joints are of the insulated type, for track circuiting, special care was necessary in the fitting and assembly of the crossings. The total length is 141 feet and the width 58 ft. 6 in.
Situated at the East End of the Central Station, Newcastle-on-Tyne., L. & N.E. Railway, and is probably the largest "concentrated" piece of manganese steel work in the world. Cornprising no less than 92 solid cast crossings and rails, it weighs, over 70 tons, and it was the third similar layout in the location above mentioned. The first one was installed in the year 1912, and the second in 1924, so that as the latter has just been renewed ·it has had a life of 14 years, which is a remarkably good performance having regard ·tp the exceptionally heavy traffic it has to contend with. This traffic embraces exceptional freight tonnages, as well as both electric- and steam passenger trains. The conditions are, indeed, probably as severe as could be found anywhere.

The Webb compounds. W.B. Thompson
May I akk the writer of the articles on the Webb three-cylinder compounds to state what exactly was done in the case of the first three engines of the Teutonic class. It appears that Teutonic herself was built with and always retained cylinders of the Dreadnought dimensions, h.p. 14 inch and 1.p. 30 inch. But Oceanic, the second engine of the class, was built with 14 inch h.p. cylinders and a 1.p. cylinder 28 in. in diameter; while the third engine, Pacific, had two outside cylinders 14 inches in diameter and one 20 inch inside cylinder. With regard to this engine Pacific The Engineer for 16 August 1889, page 143, stated:- "ThLs is not a compound but a continuous expansion engine; it can be worked with boiler steam directly in all three cylinders when a great hauling effort is required, or the steam can be expanded through all the cylinders at pleasure.
On the face of it this obscure statement appears to mean that the engine could either be worked as a compound, as a three-cylinder simple, or as a triple expansion engine. If intended for use as a compound the cylinder proportions were obviously unsuitable; if the engine was to be used as a three-cylinder simple the .boiler was too small to supply steam for [he equivalent of two cylinders 20 by 24 in. I tried at the time to obtain fuller particulars from The Engineer but was unsuccessful. Am I right in supposing that Oceanic and Pacific were soon rebuilt with a standard low presure cylinder 30 inches in diameter?

W.T.H.
Two items in the October Locomotive appear to call for further comment. The upper one of the two superimposed headlamps on the C. & N.W. Rly. 4-6-4 type locomotives, described on page 324, has a "red" lens. It is used only as a warning signal to approaching trains on the double-track line in the event of a derailmerut or other emergency. A more extended reference to this appeared in Baldwin Locomotives, October 1931, page 15.
In F. C. Hambleton's article on the Webb three-cylinder compound mineral engines (page 326), he says that No. 1880 had a Belpaire firebox with circular grate and water tube firebars. I had always understood from contemporary accounts that this engine was originally fitted with a cylindrical firebox, which was replaced about 1903 by a box of the same forrn used on other engines of the class. However, I am not at present able to find any printed reference to the matter, and perhaps my memory is playing me tricks. If the original firebox was as described by Hambleton, it would seem to merit a more detailed consideration. I hope this can be cleared up. See also response from C. Williams

"Srandagc Couplings"
Illustrated folder dealing comprehensively with the range of flexible couplings standardised and manufactured by S.P.C. (England) Ltd., of Precision Works, 100 Blackstock road, London, NA. The Standage coupling is very resilient under light torques, the resilience decreasing until it becomes sensibly constant at a predetermined value within the range of working torques. In the event of a heavy load rthe resilience decrease still further until, at a certain' point, the coupling becomes, virtually, a solid transmitter 'of the drive. This condition does not come about suddenly, however. because an oil film between each spring lamination provides a cushion which could only be broken down under excessive pressure.

A report on Strearnline, Light Weight High Speed Passenger Trains. 402
Sent by W. Howe Sadler relates that every lightweight streamlined train operating in the United States has produced additional passenger traffic and substantial earnings for the railroad placing it .in service. The Denver Zephyrs, of the Burlington lines, produced tthe highest ratio of earnings of any train of this type in the year. Other equally significant findings included the development of the Zephyr service between Chicago and the Twin Cjties, where service was started with twin three-car traius in ] 935, and grew to two seven-car trains by 1938 because of increasing demand for accommodation. There are now 76 high speed trains in operation on which modern luxury equipment has been introduced in the past four years. Of this number, 24 are of llghtweight, stainless steel construction. The first so-called streamliners went into service in 1934, with the inauguration of the City of Salina by the Union Pacific and the Pioneer Zephyr by the Burlington. Both were three-car trains, the City of Salina constructed of aluminium alloy by the Pullman Company and propelled by oil-electric power unit. The Pioneer Zephyr was built of stainless steel by the Budd Company, and was powered with a Diesel-electric unit.

account of there being two different load lines- through the centre of the pneumatic tyre when travelling on the road and through the centre of the rail wheel when carried on rail. The rear rail wheels are steel castings, 1St in. diam., bolted to a flange on the front of the hub, and on the outside of the pneumatic-tyred road wheels. The spring deadening jacks fitted to the rear axle, which are screwed down when the trailer is in the correct position on the rail truck, are oper- ated bv hand wheels at the rear of the tank which force a series of steel balls round a bent tube. These balls impinge on a piston shaped jack, the stem of which protrudes into the tube. As the rear handle is operated it pushes the balls along the tube and forces the jack down. In this manner "remote control" is obtained as well as very easy operation. In addition to the ordinary mechanical brake, double-acting vacuum brake gear has been fitted. This gives power application of the brakes when coupled to the tractor and automatic application when the trailer is uncoupled. In addition to the power application, the brakes can be mechanically operated by means of the mechanical trailer brake fitted in the cab of the tractor, operating through bell crank mechanism incorporated in the king pin, whilst a mechanical parking brake consisting of a hand wheel and screw is fitted to the front near side of the trailer. It may happen in service that the trailers arrive at the loading dock the wrong way round for coupling to the tractor and in this case they are hauled off the truck backwards. The power brak- ing has therefore been arranged so that the brake coupling on the tractor can be coupled to the back of the trailer and the trailer brakes power operated even when it is being hauled backwards. At the rear of the glass-lined tank is an internal throat consisting of a gun-metal casting to which is secured a cylindrical hot water heating tank made of copper. An electric immersion heater is screwed into the gun-metal casting, projecting through the hot water tank, as is also the thermo- stat which enables the temperature of the water to be controlled. From the heating tank rises a single "riser" pipe connected to a header tank, which has a filling orifice projecting through on top of the tank and which enables the tanks and pipes to be kept full. The riser pipe also branches into two main heating pipes which run round the sides of the tank, eventually joining together to form a single return pipe along the bottom of the tank back to the heater cylinder. As the water in the main heating tank is heated, it passes up the "riser" pipe, flows through the main heating pipes and back to the heating tank through the return pipe. A 150 amp. " [iphan" plug socket on the rail chassis provides facilities for electrical pre-heating of the tank water circulating system, or for boost- ing, should this be desirable. The piping is arranged with a cock at the front of the tank and a drain cock at the rear, so that if necessary when electric power is not available at the factory, con- nection can be made to the factory hot water supply and hot water passed through the pipes. A device is fitted to the front of the trailer for stabilising the retractable forecarriage when being carried on rail. This consists of hinged arms which hook round lugs on the forecarriage and then adjusted until it is rigidly secured. This pre- vents the retractable forecarriage from being damaged by vibration when the trailer is on the railway truck. It also locks the forecarriage and enables the trailer to be drawn off in a perfectly straight line when arriving at a loading dock the wrong way round necessitating it being drawn off backwards, to facilitate which a rear coupler has been let into the chassis rear cross member.
