High-pressure compound "Baltic" type locomotive, L.N.E.R.. 1-3. 2 illustrations., diagram (side & front elevations)
With H.E. Yarrow of Yarrow Ltd., Glasgow boiler. Four cylinder compound with patented valve gear which enabled cut off to be varied for the high and low pressure cylinders. Professor Dalby conducted experiments to optimise streamlining and smoke deflection. The wheelbase was the same as the Pacifics, but extended at the rear to accommodate a Bissel truck. Cartazzi axleboxes were employed on the trailing axles.

London, Midland & Scottish Ry. (L. & N.W. Section). 10
The output of new locomotives at Crewe during 1929 comprised two 2-6-0 mixed traffic engines, Nos. 13108-9 and 100 0-8-0 standard freight engines, Nos. 9500-99. Of these latter, No. 9599 left the works on December 30. No. 13150, the first of an order for seventy-five 2-6-0 mixed traffic engines, is expected to be ready about the middle of January. Latest conversion to class Gl (superheater) is No. 9089, which was previously class G. This engine has also been altered from steam to vacuum brake, but retains the original type of boiler with round-topped firebox.
The following engines had been adapted for working over the Midland division: Prince of Wales class, Nos. 5649, 5750, 5837; George the Fifth class, No. 5360; Experiment class, No. 5496; 19-in. goods class, No. 8834.
L.T.S. 4-6-4 Baltic tank No. 2193 (late No. 2101) had been broken up at Crewe. Other recent withdrawals were: 4-4-0 Renown class (formerly four-cylinder com- pound), Nos. 5113 Colossus, 5123 Caesar, 5133 Collingwood, 5170 Trafalgar: 0-4-2 shunters, Nos. 7864, 7868, 2-8-0 M.M. class, No. 9658.
0-6-0 standard freight engines Nos. 4101-2 had been transferred to the Midland division.
At the end of 1929, the number of ex L. & N.W. 0-8-0 tender engines in service was 539, comprising six distinct classes, as follow:-G2 (60), Gl (383), G (41), D (25), Cl (24), C (6).

The last of the 0-8-0 tender engines, No. 9599, left the Crewe Works when they re-opened on 30 December. The 100 locomotives of this class had therefore been completed in about nine months, but in the 1870s F.W. Webb turned out considerably over 100 each year, the total for 1872 being 145, which is still the record.
The Crewe tramway engines had been withdrawn with the exception of Billy and Pet, and these were likely to follow in the near future. Under the reorganisation scheme, "scooters," which ply from shop to shop, play a very important part in the movement of materials, thus rendering the tram engines useless. It is worth noting that the boilers of these tram engines had not been replaced since they were built, the same boiler being used for the same engine throughout. One or two of the engines had seen seventy years' service.
A further twenty-five 2-6-0 engines have been put on order at Crewe, making seventy-five altogether

Nineteen-twenty-nine saw the disappearance of the last South Devon Ry. engine (excepting, of course, Tiny on Newton Abbot platform). This was G.W.R. 925, originally S.D.R. Rook. When taken over from the South Devon it became G.W.R. 2176 (Avonside Engine Co. 1053), and later 1330. In 1906 it was sold to the Swansea Harbour Trust and became their No. 7, and later was transferred to Powlesland and Mason and was No. 7 on their list also. At the grouping it became G.W.R. No. 925. There was still one Bristol and Exeter engine left, now G.W.R. 1376.

[French locomotives for Andalusian Railways]. C.H. Dickson. 107
In article on pages 50-53, mention is made of French engines built for the Andalusian Rys. Writer had no information at all concerning those built at Le Creusot, and should be glad of any details, those built by the to Alsacienne are as follows:—
F.C. de Andaluces Nos. 251-270, built at Grafenstaden 1890-1, WN 4140-4159, type 0-6-0 tender, cylinders 450 mm. diameter, 650 mm. stroke, driving wheels 1.500. F. C. de Andaluces Nos. 301-310, also built at Grafenstaden, 1901-2, maker's numbers 5086-5095, type 4-6-0 compound tender, H.P. cylinders 350 mm. x 640 mm., L.P. 550 mm. x 640 mm., driving wheels 1.62 metres. These ten engines were of the same type as Midi Ry. of France No. 1401, built at Belfort in 1896, except that they conformed to the Spanish gauge, i.e., 1.676 metres. I should be much obliged to any reader for any information concerning ten engines, type 0-6-0 tender, built by Koechlin at Mulhouse in 1870 (WN1253-1262). They were originally built for the Memphis, El Paso and Pacific Ry., but were never delivered as this company went bankrupt; they were to have been Nos. 1-10, but never left Europe. They were sold in Spain and Portugal partially, the rest were broken up at Mulhouse.

[James Stirling singles]. Malcolm McL Niven. 107
As there seems to be a great many engines being scrapped by the L.M. & S. Ry., and as the old Stirling bogies rebuilt by James Manson in 1901 are going, could one of them not be rescued and sent to York? They were James Stirling's first bogie engines, and similar to the South Eastern machines with, of course, a few technical modifications. E.L Ahrons went deeply into their history with me by corresponcence and wrote about them in his article in your issues some six years ago, when much valuable information was given to the world through your columns about the engines of the G. & S.W. Ry. Co. I feel sure such fine old models deserve a niche in the shrine along with Patrick Stirling's 8 ft. No. 1, and Stroudley's "Gladstone," No. 215.

The Locomotive Engineers' Pocket Book, 1930. London: The Locomotive Publishing Co. Ltd.
This useful pocket book has been again thoroughly revised and new matter inserted in place of that which has become out of date. This particularly applies to the tables of leading dimensions of the chief classes of locomotives of the British and Colonial as well as American and Continental railways. A complete set of dimensions of the latest standard designs of broad and narrow-gauge engines for the Indian Railways is included for the first time. In spite of the mass of useful in-formation for the every-day reference of the practical loco-motive or running department official, the book is kept within pocket size. At the back is a directory of the chief mechanical engineers and locomotive and carriage superintendents of all the railways in Great Britain, the Colonies, Dominions and India, South America and China, and also a directory of Industrial Works in this country owning locomotives, arranged in very convenient form. The section on running shed work and routine must be a boon to all locomotive foremen, whilst the tables and memoranda are invaluable for reference. In addition we may say the book is strongly bound and clearly printed on good paper.

The locomotives of the Southern Ry. (Western-Section). London: W.G. Tilling.
For those interested in the locomotives of the former London and South Western Ry., the latest book published by W.G. Tilling, supplies a long-felt want and can be well recommended. Each class of engine is dealt with in a concise form and there is a goodly supply of interesting historical notes hitherto unpublished. The principal dimensioris of each class are given in tabular form at the end of the book. The list of the present locomotive stock at the end helps to make the book very useful for reference, and sufficient space has been allotted to enable the purchaser to keep this list up-to-date, if desired. The book is full of illustrations, well reproduced, and to us who read much railway literature, it is a pleasant change to see new photographs. Two slight errors have crept in, possibly in printing. On page 22 the first word should be "Western," and in the list of locomotives on page 43, the name of engine No. E770 should read Sir Prianus. To those who dabble in the compilation of locomotive history, the work shows signs of many hours labour and research. It is well produced on art paper, and in conjunction with his two previous books dealing with the locomotives of the L.B. & S.C. and S.E. & C. sections, it forms a unique record of the locomotive stock of the Southern Ry. as a whole. Altogether, - the author is to be congratulated.

Agenda Dunod 1930 Chemins de Fer, by S. Peace. Paris: Dunod et Cie.
49th edition of this well known French Pocket Book dated 1930 has been received. It contains as usual tabulated matter indispensable for those connected with operating and working of railways, steam and electric. Locomotives, rolling stock, permanent way, signalling and operation are all pro-vided for in this comprehensive work. The latest types of locomotives as adopted by the French railways are fully discussed as also the various approved details of construction.

The Locomotive and Carriage Institution. 107
At the meeting on 8 February 1930, held at Caxton Hall, Westminster, a most interesting paper on Southern Ry. locomotive policy and progress was read by J. Clayton, M.B.E., M.I.Mech.E. The author described the details of improvements to the Urie 4-6-0 engines on the Western section, which were made in stages to see the effect of each alteration, ports being enlarged, chimney and blast pipe adjusted, valve travel lengthened, and finally cylinders reduced in diameter. The results of this patient research were put into the King Arthur type. The principal features of the standard Southern locomotive types were then discussed. These standard types include the four-cylinder Lord Nelson 4-6-0 class, for express passenger duties; the so-called "light" School class 4-4-0, which will be one of the biggest engines of this wheel arrangement; the three-cylinder 2-6-0 class for mixed traffic; the 0-8-0T with three cylinders, for shunting; King Arthur 4-6-0 types with varying wheel diameters for both fast passenger and heavy freight work. Clayton concluded with a review of locomotive progress in this country, and pointed out the moral that even if those responsible for locomotive design had to experiment warily and not spend too much on untried expedients, yet locomotive progress was made fairly rapidly. E.C. Poultney, in a long contribution to the discussion, produced figures showing the King Arthur class locomotives to be within measurable distance of the efficiency of the German 900-lb. pressure compound locomotive —a remarkable achievement for a simple engine design.

A list of printed and illustrated material on the Liverpool and Manchester Ry. in the Reference Library. City of Liverpool Libraries, Museums, and Arts Committee, 1930. Price 2d.
In view of the widespread interest which has been aroused by the forthcoming celebrations of the Centenary of the opening of the Liverpool & Manchester Ry., the City of Liverpool have published a catalogue of the printed and illus- trated material bearing on the subject, which is to be found in their Reference Library. This book, which will be of great service to visitors to the coming events, begins with an account of the opening of the line extracted from the Mechanics' Magazine of September 25, 1830. Thereafter follow the various sections of the catalogue, (1) the early surveyors and engineers, maps, biographies, portraits, etc. (2) Parliamentary and miscellaneous reports, (3) Acts of Parliament, (4) maps, plans, etc., (5) history, description and views of the line, (6) locomotives and stock, and (7) miscellaneous, concluding with a facsimile of a ticket issued September 17, 1830. As a frontispiece a reproduction is given of the famous picture of the opening by I. Shaw, showing the scene at the Moorish Arch. This catalogue is of more than a passing interest, and forms a useful permanent record of literature and other published matter relating to the railway. Ottley 6360.

Highland engines and their work. C. Hamilton Ellis, London: The Locomotive Publishing Co. Ltd. .
"Ihe isolated position of the Highland Ry., the extreme northerly points to which it penetrated, the immense difficulties with which it had to contend due to the mountainous and sparsely populated district which it served and the terribly severe climatic conditions it had to endure, coupled with the highly efficient and well kept stud of locomotives with which its traffic was worked, gave it a sentimental interest which appealed to all railway enthusiasts, and now that these conditions have in large measure disappeared since its absorption in the L.M. & S. group, a record of its independent existence will be welcomed by all who knew it. This record Mr. E11is has endeavoured to supply, and although very much more might have been written as to its history and romance, even this brief account of some 120 pages will be appreciated. A more detailed description, both of the history and the locomotives of the line, appeared in our columns between June, 1915, and July, 1920, but as most of this period was covered by the Great War, these issues are now very scarce. This history appears to have formed the basis of Mr. E11is' book, and most of the forty-seven blocks with which it is illustrated are reproduced from it. Naturally the author deals extensively with the naming of the Highland engines, but we fear he is mistaken In stating that "it is indeed a tribute to the memory of our national hero that no less than three Highland engines should bear his name one after the other." It is quite true that in 1874, 1884 and 1886 new locomotives, each bearing the popular name of "Bruce" were added to the stock, but the Highland's propensity for perpetuating the names of its directors and their residences is well known, and it has always been understood that the engines in question commemorated the Hon. Thomas Charles Bruce, deputy chairman from the inception of the company until 1884, and chairman from the latter date until 1890. In a final chapter a summary is given of the L.M. & S. renumbering, which, although only dealing with the engines in groups, will be found useful to those who desire to follow their subsequent careers.

"Highland Enqines and their Work."   K.R.M. Cameron. 358-9
See review page 287. In connection with the above book, I trust you will permit me to make a few corrections and observations. I may say, here and now, that I wish to thank Mr. Ellis for taking such pains to present a book on a subject which has been un- deservedly neglected in the past, but being somewhat jealous of the Old Highland Ry. locomotives, I would not like a history of them to contain even the slightest error. I will deal with such inaccuracies as I have come across, and which only concern those engines in service at the time of the amalgamation.
Frontispiece.-The "Loch" class are not being reboilered with Dunalastair IV boilers, but with 812 class CR. goods boilers. (Typical engines are L.,M.S. 17550-17645.)
P. 50, line 4.— "had 4 ft. 9 in. coupled wheels.' should read "had 5 ft. 3 in. coupled wheels."
P. 54, line 4.— For "3 ft. 2 in." read "3 ft. 3 in,"; line 8- tube heating surface is 1,559 sq. ft .. not 1,359 sq. ft.; line 21- for "Jones Goods" read "Big Goods."
P.  56, 11, 1-5.— As noted for frontispiece, not Dunalastair boilers. I also question the statement that they "literally 'ate' coal," as the 812 class boilers have a good reputation on the C.R. section for their steaming powers.
P. 65, plate.— The captions under the two illustrations should be transposed, as the original "Barneys" had no water tubes. The 18 class, built later, were fitted with water tubes. Actually, the photographs confirm this statement.
P. 66, plate— The lower photograph should be named "Mr. Drummonds 'New Ben' class 4-4-0."
P. 68, 11, 23-24.—Nos. 134-139 did not have Drummond's cross water-tubes in the firebox.
P. 69, 11, 7, 8.—"six more ... Nos, 18-21 and 36-7, were similar to the English engines in this respect" should read "were dissimilar to the English engines in that they were fitted with water tubes in the firebox."
The statement occurring on the same page (69), lines 16-18, confirms my remarks, as 17702 is old H. Ry, 21.
P. 71, line 26.—"Murthley" should be "Murthly."
P. 72, 11, 20-23.—The double bogie tenders supplied with the "Castle" class were different from those supphed with the original six  "Barneys," and are not interchangeable. The full weight of these tenders is 44 tons 9 cwt., not 38 tons. Mr, Ellis also does not mention that the last three engines of the "Castle" class had 6 ft. dia. coupled wheels and six-wheeled tenders.
P. 73, line 29.—-For "Big Bens" read "New Bens."
P. 75, line 14.—For No. 14909 read 14409.
P. 79, lines 2-5.—It should be mentioned that Nos. 40, 25, 45, 46, had coupled wheels 4 ft. 6 in. in diameter, as compared with the rebuilt Jones 0-4-4T, which had 4 ft. 3 in. wheels, Line 14.— "coupled wheels 5 ft. diameter" read "coupled wheels 5 ft. 2½ in. diameter."
P. 94, line 24,—For "160 lb." read "175 lb." 11, 30-31,— Durn and Snaigow were followed by three "Castle" class engines (Nos. 50, 58, 59) with six-wheeled tenders before the advent of the "Clan" class.
P. 97, line 9.—For "170 lb." read "175 lb." Line 24.—For "5 ft. in diameter, 20¼ x 26 cylinders" read "5 ft. 3 in. in diameter, 20½ x 26 cylinders."
P. 102, plate.—For "Fordinard" read "Forsinard."
P. 114. Renumbering list.—14756-14761 are not known as the "River" class, but as the 938 class. 15010-15012 Jones 4-4-0T. 15013-15017 "American" 4-4-0T, 15051-15054 Drurnmond's 0-4-4T.
P. 115, lines 11-20.—The "Small Bens" have not been rebuilt with Dunalastair boilers, but with C.R. 18 in. x 26 in. goods boilers. (Typical engines are 17230-17473.) Also, the remark that "gone is the graceful outline of the original 'Small Ben'" is, I think, rather exaggerated, as the engines still retain their original chimney—unless it requires renewal when a chimney of almost identical pattern is put on—the framing and cab of the old engines is either retained or renewed to the original drawings, the height of the old boiler centre line above rail level is the same as before, and the old tenders are still used. Regarding the "hybrid Dunalastair" remark, I do not think that even the most enthusiastic "Small Ben-ite" could ever deny that they always have resembled a Dunalastair.
I do not understand how the steaming powers of the "Small Bens" have been spoiled when rebuilt, as the 18 in. x 26 in. C.R. goods boiler is perhaps the easiest steaming boiler I have come across, as witness the very fine performance of the 18 in. x 26 in. engines on fast passenger services on the CR. section.
P. 115, line 23.—For "original" read "second."
The foregoing covers all the errors which I am aware of, and I can vouch for the accuracy of the corrections. Generally speaking, the book fills a want in the history of Scottish locomotives, but I, personally, am disappointed that in a history of the Highland Ry. engines, the frontispiece should be an engine in the L.M.S. livery. The same photo- graph is ruined by the very obvious attempt to touch up the name on the engine, and the fact that the engine has been rebuilt with a boiler from another section of the railway renders the picture quite unsuitable as a frontispiece. The "Clan" class could, with advantage, have been presented in the original colours, and although these engines have all been repainted, photographs of them in the H.Ry. livery are still obtainable.
I do not agree with Mr. Ellis' remarks re electrification and the "gliding over the gradients with the ease of a steam train on the level and at a fifth of the present cost." That, however, is a very controversial subject, and I will not enlarge on it.
Regarding the corrections, I think it would only be fair to those people who have bought the book, to issue them with an errata slip, which could be gummed at the back of the book. As it is, as far as I know, the only co-ordinated history of the H. Ry. locomotives, it will be looked upon in the future as a correct record, and as such, should be made as nearly correct as it is' possible to make it.
I trust that Mr. Ellis will not mistake the spirit of this criticism, which is being made to do justice to my favourite railway, now unfortunately defunct.

The Drolshammer Air Brake.  C.A. Branston.
The Drolshammer triple valve and the principle on which it works constitute such an interesting departure from hitherto received air brake practice that I trust the following comments on your latest note thereon (p. 278) may serve to bring out somewhat more clearly its action and principles, and will, I hope, elicit further information as to its working. It is stated that the maximum brake cylinder pressure depends on :-
(a) The action of spring 13 on piston 12.
(b) The pressure in the auxiliary reservoir after a full service application.
(c) The volume of the auxiliary reservoir; and
(d) The swept volume of the brake cylinder.
As to (a): The spring is simply the non-rigid connection between pistons 1 and 12. and as spring 11 serves merely to balance the unbalanced area of piston 115, it follows that the force acting upwards on piston 12 is due to the difference between the pressures in action chamber 39 and in the brake pipe; as the pressure in the former is nearly constant, we come to the result that the varying factor here is the brake pipe pressure, or, in other words, the brake pipe reduction. As to (b) : This can hardly be called an independent factor as it depends on (c).
Hence we see that the maximum brake cylinder pressure depends on: The brake pipe reduction; the size of the auxiliary reservoir; and the swept volume of the brake cylinder; but this is the case with all air brakes (not using safety valves).
It is further stated that equalisation between brake cylinder and auxiliary reservoir cannot take place, but it is not clear either why or how this should be so if a full service reduc- tion is made.
The action of the S.A.B. Svenska slack adjuster would seem to be wrapped in mystery, but it must be a powerfully conceived piece of mechanism which, with the primary purpose of adjusting the slack in the brake rigging, yet automatically not only takes care of this aspect of the brake problem, but equally well acts as the controlling device for the load and empty brake cylinders with their different volumes, clearances, and pressures. I am sure it would be interesting to have a proper illustration and clearer diagrams of the action of this mechanism, and especially of the change-over mechanism of the Drolshammer brake, with which you have not yet dealt.
The reference to a "zero" piston stroke in connection with the notched push-rod of another make of load brake is enigmatic; with a piston stroke of 0, the force transmitted would equally be 0, and so would be the result as far as stopping the train goes.
That the brake system using the notched push-rod is not necessarily doubtful in operation under wintry conditions may be surmised from the fact that, though designed originally to solve the braking problems of a particular railway using 140-ton mineral cars (108 tons net load), this brake is now being used generally by other lines in the United States for freight cars where the loaded- differs greatly from the empty-weight.

Restoration of historic locomotives. C. Hamilton Ellis 359
We are told that Ruskin considered any man who would restore a church nothing more or less than an unmitigated sweep, and in some ways the same applies to the restoration of historic locomotives. (Of Ruskin's views concerning the Iron Horse, the less said the better.)
At the same time, one cannot do less than applaud the manner in which the old Liverpool & Manchester Ry. engine Lion has been invested with her pristine glory, while the reconstruction of the Great Western Ry. North Star, being a literal restoration, goes without saying as a laudable effort.
It would, of course, be little short of sacrilege to cut the old Cornwall about until she assumed her original freakishness, the more so as it was in her present form that she really became famous. On the other hand, surely nobody would object if the old North Western Ry. engine Columbine were deprived of that shapeless and preposterous cab which now adorns her footplate, hiding the dome, and completely spoiling the effect of the remarkably beautiful Alexander Allan design. Columbine's cab has no useful purpose to fulfil as it had in the days when she was Engineer Bangor; why, then, should it remain, disfiguring the engine as it does?

It is a very simple device, which gives a short blast on a horn on passing a distant signal at danger and a prolonged blast and an application of the brake on passing a stop signal.

At a board meeting on 30 October 1930, appointed Sir Henry Fowler, chief mechanical engineer, to be assistant to the vice-president for works as from 1 January 1931. It is intended that Sir Henry Fowler's knowledge and experience should in future be devoted to research and development, and he will take charge of the company's laboratories and the central testing bureau. E.J.H. Lemon, the company's carriage and wagon superintendent, has been appointed to succeed Sir Henry as chief mechanical engineer, and he will take charge of both locomotive and carriage and wagon workshops.

London, Midland & Scottish Ry.(L. & N.W. Section). 363
Additional 2-6-0 mixed traffic engines recently turned out from Crewe bore Nos. 13208-17. Of these, the first five were in service on the Northern division, the remainder being stationed at Crewe South shed awaiting transfer thereto. The new Royal Scots ex Derby were delivered up to No. 6166, this latter at present being nameless. Several of these engines were stationed at Holyhead for through working to and from London on the Irish mails—a service which was previously performed by the rebuilt Claughtons, fitted with Caprotti valve gear, though occasionally one of these latter could still be seen on this service. Two further additions to class "G1" (superheater) were Nos. 9035 and 9045, both of which were formerly class "D." No. 9035 had been provided with an ordinary round-topped boiler, whilst No. 9045 had a standard one with Belpaire firebox. In accordance with usual practice, the power classification of these engines had been raised from 5G to 6G. Nos. 5940 and 5964 4-6-0 Claughton class had been transferred to the Midland division. No. 5325, George V class, had the cab altered to suit the Midland loading gauge. Engines recently withdrawn from service included 2-4-0 Jumbos, Nos. 5408 Henry Pease, 5064 Chandos, 5087 Narcissus; also the following :—Renown class, No. 5155 Irresistible; 0-6-0 18-in. goods, Nos. 8434, 8474, and the last of the N.S. Ry. H class 0-6-0 goods tender engines, No. 8688. This latter was built at Stoke as No. 92 in 1911, afterwards becoming No. 2366 in the L.M. & S. Ry. list, and still later No. 8688.

Victorian Rys. 363
Four engines of the S class three-cylinder Pacifies were in service, Nos. 300 to 303: an improved front-end arrangement, on American lines, being embodied , and their steaming capacity greatly improved. Ten further engines of the 2-8-2 light N class (see THE LOCOMOTIVE, May 15, 1927), were approaching completion at Newport shops. This would complete thirty of this useful class, Nos. 110 to 139. Ten petrol-electric rail motors were now running, and some on the main line pulling trailers. An interesting feature is, that as these cars had motors similar to those used on the electric stock around Melbourne, it was proposed to fit them with pantographs for operation by the main supply when they enter the electric train area. A number of the DD 4-6-0 mixed traffic engines had been fittted with larger boilers, giving an additional 300 sq. ft. of heating surface. There are about 260 of this class in service.

Re Hamilton Ellis's article in last issue, a correspondent informs us that there were eight survivors of this class (D51) last month, five being attached to St. Margaret's Shed, Edinburgh, and three on the G.N.S. section at Kittybrewster, Aberdeen. The numbers are 10406 (N.B. 111), 10425 (98), 10428 (104), 10429 (105), 10458 (99), at St. Margarets, and 10456 (74), 10461 (294), 10462 (52), at Kittybrewster. The last two are fitted with cowcatchers at each end for the St. Combs' branch. Nos. 10429 and 10428 work the Lauder and Gifford branches respectively.

H.P. Stewart had been appointed locomotive engineer of the N.C.C. in succession to W.K. Wallace, who had taken up his duties as chief stores superintendent of the L.M. & S. Ry. at Euston. Engine No. 66, formerly a two-cylinder 4-4-0 compound, had been rebuilt as a simple engine, class A1, fitted with a 200-lb. pressure, G6 boiler, and has been named Ben Madigan.. This is the proper name of Cave Hill, which overlooks Belfast. Engine No. 62, of the same class, with the standard G6 boiler, is being named Slemish, after a mountain near Ballymena. There are now six engines of this class, viz.;-34, 62, 64, 65, 66, and 68.

Concluded from page 381.)
Little comment is required on the modern tender. The need for a self-trimming type is generally admitted, and those in use are quite satisfactory, the introduction by the L.M. & S. Ry. of an entrance door to the coal space being a valuable feature. It is a curious thing that no British railway seems ever to have provided any better means of access to the tank filling hole than the awkward scramble over coal and fire-irons. Many Continental and American designers narrow their coal space so as to provide a gangway along the tank top to the rear end of the tender. Of course, water troughs have done away with many tank-filling scrambles, but even so, water columns will always be necessary in some locations. And here a word on the subject of water columns. In pre-grouping days, some railways provided columns that could be operated by one man. The fireman could ascend the tender, pull up the leather pipe, and turn the water off and on where he stood . Now these are being replaced by standard columns, which require the services of two men-one to haul round and insert the pipe, and the other to stand on the ground and adjust the feed-surely a rather retrograde step in these days of improved working! A water-stop is invariably the place where the driver wants to employ the time in lubrication and inspection, or the fireman wants to attend to fire-cleaning. Now they have both got to stand by the water column, and many valuable minutes are lost. Added to which, no man on the ground can adjust the feed so accurately as the man on the top who is watching it fill, and an overflow into a tenderful of indifferent coal can produce a very bad trip indeed.
Now, it may be thought by the foregoing that British enginemen must be inveterate grumblers, but this is far from being the case. They have their likes and dislikes, but generally speaking, they adapt themselves to circumstances, and the old style of driver who condemned an engine in its entirety because he did not approve of its sanding gear is not much in evidence now. It is a curious fact that firemen seem to have little objection to shovelling a large amount of coal. A fireman will go quite cheerfully from an engine burning 40 lb. of coal per mile to one consuming 60, and beyond remarking that his new charge is "sore on stuff" will make little comment. But let

The Parkmore branch and the Ballyboley to Doagh narrow gauge lines arc being closed to passenger traffic. The Parkrnore branch was built in the early 1870s and opened as the Ballymcna, Cushendall and Red Bay Ry. for the transport of iron ore to the main line. Later, passengers were carried, and in 1884 amalgamation with the Belfast and Northern Counties Ry. took place. The Parkmore line was the first narrow gauge railway in Ireland. None of the original locomotive stock remained. Nos. 1 and 2 were scrapped in 1923 as N.C.C. 101 and 102. No. 3 was scrapped in 1908 as N.C.C.

Correspondence. 431

Engineering Department, locomotives of the London & South Western Ry. F.W. Brewer
The article on the above subject affords a very interesting additional chapter in the history of the locomotives of the old L. & S.W. Ry.
It will be noticed that several of the engines mentioned in the article bore the surnames of people who were either directly or indirectly connected with railways. In the case of the engines, Yolland, Rich, and Hutchinson, there is little, if any, doubt that these were named after three of the then four inspecting officers of the Railway Department of the Board of Trade, viz., Col. W. Yolland, C.B., Col. F. H. Rich, and Major- Gen. C. S. Hutchinson, all of whom were R.E.'s. Of what one may call the railway inspecting officers of the old school, there still remains an ex officio one in Sir H.A. Yorke, C.B., who retired from the Board of Trade some years ago, and who recently resigned from his position as a director of the G.W. Ry. Referring to the drawing of the outside-cylinder 2-4-0, Hutchinson (Fig. 11), it may be remarked that the peculiar arrangement of the springs and bearings of the leading wheels is similar to that adopted by Mr. Joseph Beattie, but the corre- sponding engines of the Holland Ry. had these springs placed inside the frames.
The method of balancing the motion parts of the 2-4-0 tank engine, Scott (Figs. 12 and 13), is also worth noting. Instead of there being counterweights both in the driving and in the coupled wheels, the balancing is confined wholly to the latter, i,e., to the trailing wheels.

Breakdown cranes, etc. Wm. T. Hoecker.
On page 171 of the May LM you describe the crane there illustrated as "the largest . . . yet constructed in the British Isles." I would remind you that in 1926, Cowans, Sheldon and Co. Ltd., of Carlisle, delivered to the South Australian Railways two steam wrecking cranes, each capable of lifting a maximum load of 107 tons.
It may be of interest to note that a crane recently built for the Union Pacific RR, by the Bucyrus Erie Co., has a lifting capacity of 178 English tons at 17t ft. radius On the auxiliary hook, 40 English tons can be lifted at a radius of 48 ft. This is an exceptionally large crane, as the average American crane has a maximum capacity of from 125 to 150 short tons. Permit me also to offer two comments on Mr. Phillipson's article on pages 241-2 of your July number:
1. The usual thickness of steel plates for inner fireboxes, as used in American practice, is as follows: Side, crown, and back sheets, ! in. tube sheet, t in. to tin.
2. About 33,000 locomotives in the United States are now equipped with mechanically-operated firebox doors.
