Locomotive history is probably easiest to appreciate if it is examined in chronological order. The differences between goods engines and passenger engines are blurred: frequently mixed traffic locomotives or hybrids as known in Ireland, dominated affairs as with the Stanier Class 5. Tank engines had specialized niches and the RCTS green books (Locomotives of the LNER) segrated into a separate series. No doubt this reflected Thompson's renumbering scheme, but surely the L1 2-6-4T has much in common with the K1 2-6-0. This page originated as an attempt to follow the structure adopted in_Steam locomotive development_ (which followed that of the RCTS green books), but this produced too much cross classification and thus is being modified to become strictly chronolocical: thus there are McDonnell, Coey and Bredin sections. This shoukl assist accommodate the extra information provided viaClements and McMahon's Locomotives of the GSR. After the 1925 amalgamation this, the largest Irish company, was comparable in size with some of the English pre-grouping railways. Its main-lines ran from Dublin to the South and West. With the exception of the line to Cork, traffic on most of the system was sparse and trains were infrequent. In consequence, the locomotive stock was relatively small and the replacement rate was low. One strange anomaly needs to be mentioned. The Dublin & Kingstown Railway was the first Irish railway. It was built to the Great British standard gauge and had obvious links with the London & Birmingham Railway, yet no mention is made on its probable influence on Great Southern & Western locomotive policy.. NeitherAhron's The British Steam Railway Locomotive 1825-1925. nor James W. Lowe's British steam locomotive builders have much to conrribute on early GSWR locomotives. Thus**Clements, McMahon,& O'Rourke.** is a major contribution.
E.E. Joynt's "Reminiscences of an Irish locomotive works" provide an "inside view" of activity at the well equipped Inchicore Works, but mainly surveys the period which preceded 1923. In its way it is a precursor of Holcroft and Cox. .J. Watson's book consists of tabulated data and brief notes on the locomotive stock. See also Locomotives of the GSR, Ireland published in 2008: see latter from Jeremy Clements and Michael McMahon (Steam Wld, 2008 (248) 19 with this vital news).
Lowe notes that the railway was incorporated in 1844; the works at Inchicore were established in 1846, but that the first locomotive was not constructed there until 1852; reliance being placed on Bury and Sharp products until then. .

Appendix B: Motive power fleet totals. (pp.345-50)
During the 20 year life of the Great Southern Railways, the company continued to submit Annual Reports in the standard format that had previously accorded with the First Schedule to the Railway Companies (Accounts and Returns) Act, 1911. These documents included statistical data on the financial condition of the company and also on the numbers of locomotives, carriages and wagons in service at each year end.
Previous commentators have had difficulty in reconciling the reported locomotive totals with the actual . numbers known to have comprised the fleet at specific times. These differences might have occurred through clerical recording errors but it is likely that ambiguity in the operational status of certain locomotives also contributed to discrepancies. As was concluded in theMilne Report, the GSR's fleet size was significantly larger than average traffic levels actually demanded. With comparatively low utilisation, there must always have been plenty of locomotives on hand at depots for the work available, and it is reasonable to assume that some must have stood out of service for considerable periods. Equally there would have been a number of locomotives standing at Inchicore for long periods awaiting a decision on withdrawal, or refurbishment and return to duty. In such circumstances, uncertainty over the precise status of some locomotives would have complicated the count.
The existence of certain locomotives in this form of limbo is well known. For example, ex-CBSCR 4-6-0T No 471 stood at Inchicore awaiting its fate for around six years before withdrawal. The four ex-Cork Blackrock & Passage Railway 2-4-2Ts were-officially withdrawn in 1933, then refurbished and reinstated for further work on the Cavan & Leitrim section the following year. On the other hand, ex-Cork & Muskerry Light Railway 0-4-4T No 5 was withdrawn in 1935 and several reports claim that it was then transferred to the Tralee & Dingle section, when in fact it was cannibalised to keep CMLR No 6 serviceable for use on the Schull & Skibbereen section.
Other formally recorded withdrawal and later reinstatements were comparatively few. Ex-MGWR 4-4-0 No 545 was withdrawn and reinstated during 1933, working for another 22 years. Ex-GSWR 2-6-0 No 357 stopped work in 1931 but returned to service four years later. It is reasonable to assume that others went through this cycle but were not formally recorded as such in the annual returns.
The physical count might also have been distorted by the status of locomotives on departmental duties. There was no renumbering or special type of identification for locomotives in this category and counting errors could easily have resulted. Uncertainty over departmental status is usually attributed to the otherwise inexplicable addition to the fleet of one 0-6-0 in 1944.
Table 1 below shows the figures as recorded in the annual returns. Table 2 summarises the withdrawals and additions to the fleet in the period 1925-1944.
These figures are based on locomotives that were allocated GSR numbers, ie recorded as such in the company's asset registers. Thus, the DSER locomotives which had already been withdrawn (or were about to be) but nevertheless came into the GSR's possession in 1925, have been excluded. Also in this category is the curiosity of DSER No 44, which was never given a GSR number but actually worked on normal duties until 1927.

Chief Mechanical Engineers

Early locomotives
KPJ has had to depend uponRowledge for the period between the formation of the Great Southern & Western Railway and the arrival of McDonnell. As usual for this period the railway was served by a mixture of Bury and Sharp locomotives.

Bury, Curtis & Kennedy
Both 0-4-2 and 2-2-2 types obtained from 1845. Although the series of 2-2-2 bought from Sharp Brothers were given lower numbers than the Bury type Clements, McMahon and O'Rourke consider that there is evidence to suggest that the Bury lomotives were ordered earlier

2-2-2
No. 21. delivered August 12845; withdrawn June 1873. Shipped new to Drogheda for trials on DDR. Rebuilt in 1865 with new boiler & cylinders. Worked at GSWR foundry until 1875.
Running numbers 21-2: 1845
Running numbers 23-9: 1846
Running numbers 30-6: 1847
Running numbers 37-40: 1848

Bury No. 36 illustrated in Bulleid, H.A.V. Aspinall era. p. 45
Photograph ordered by H.A. Ivatt when No. 36 was cut up at Inchicore in 1886, having been withdrawn from service in 1872.

0-4-2
Running numbers 41-2: 1845
Running numbers 43-7: 1847
Running numbers 48-50: 1848

Grendon of Drogheda supplied two 0-4-2 in 1849 and these were numbered 51-2: these were similar to Grendon products supplied to other Irish railways. (Lowe).

Planned as an order for ten locomotives with deliveries from June 1854; extensive delays led to the order being reduced to six in September 1854. Two were delivered in August 1855.The GSR declined to accept the remaining four, but one was delivered to the Waterford & Limerick Railway in December 1855 as No. 21

It then participated in the Stockton and Darlington Centenary celebrations in 1925 and at the Royal Dublin Society Bi-Centenary celebrations in 1930.

0-6-0: 1866: 101 class (Class 3) J15 RNC XXXV
Clements, McMahon,& O'Rourke. pages 125-33 give a concise history of this, the most numerous, of Ireland's locomotive classes. It is accompanied by 5 photographs and 5 side elevation drawings and shows how the locomotives were fitted with larger boilers, and one was modified as a two-cylinder compound. The prequel nature of this work is rather too evident with this class as with tthe ultimate developjment the reader is diirected to Clements and McMahon without as much as a page reference: Wikipedia is far better in citing page 83.
The lucid Norman Johnston (Locomotives of the GNRI) makes it clear that the design originated at Beyer Peacock in 1867: two were built for the Dublin & Belfast Junction Railway and became part of GNRI stock. Bulleid:Aspinall era Text and Table p. 40 notes that design had 5ft 1¼in coupled wheels; 17 (later 18) x 24in cylinders, a grate area of 17½ft2 and a total heating surface of 957 ft2.Clements and McMahon (page 76 et seq) succinctly state "Their robust simple construction made them great favourites with locomotive crews band shed staff, while their reliability and economy in operation pleased the financial managers." Notes that class had a superficial similarity to the LNWR DX Goods, but consider that the design was developed by Beyer Peacock at McDonnell's instigation. Some locomotives were in service for over ninety years. The average working life was 75 years. The 1948 assessment was generous and noted that they could work over most lines. An English postscript suggests that NER 59 class (LNER J22) was an enlarged version of the 101 class and included GSWR features including cab and sloping front smokebox with double doors. Clements and McMahonpage. 83.
The following came from page 83 of a book which had been photocopied, but its source was not recorded! Their robust. simple construction made them great favourites with locomotive crews and shed staff. while their reliability and economy in operation pleased the financial managers. They continued in a broad range of duties. fundamentally unchanged throughout their long working careers and were to be found on every type of work. including express passenger where they were often called upon to act as pilot engines especially on the departure from Cork.

Experimental modification by Ivatt as Worsdell Von Borries two cylinder compound
Clements, McMahon,& O'Rourke. pages 48-9 cover the conversion of 101 class No. 165 in March 1891 to a two-cylinder compound (and to a lesser extent 60 class No. 93 to a similar modification. The 0-6-0 was fitted with an automatic flap valve which enabled the locomotive to start in simple mode, but the 4-4-0 changeover was performed by the driver. Joynt who observed No. 165 on the Nenagh freight said it was undesired and unloved. Its exhaust was irregukar and asthmatic probably due to the exposed location of the low prseeure cylinder which acted as a condenser. Neither was successful and they were simplified in 1896 (165) due to a cracked frame and 1906 (No. 93) during major repairs.

Contributions from the Editor, K.A. Murray, R.N. Clements, J. O'Neill and J.J. Johnston survey all aspects of its long history; appropriately 101 out of the 119 locomotives are illustrated and several photographs are Victorian marvels. The text of the book is effectively a number of essays, some from the original 1966 publication, the remainder written to add to and bring the story up to date. The 'historical' essays, outlining the development of the type are by R.N.. Clements, there is a driver's appreciation by the gentlemanly Jack O'Neill from Waterford and, presumably from the original edition, an essay entitled 'A Valuable Asset' gives an appreciation of the merits of the class from the point of view of the CIE's mechanical engineering department. The story is brought up to date through the travels and exploits - mainly cinematographic - of the preserved locomotives, Nos.184 and 186, and appropriately the final essay, by one of the named authors, details the recent restoration ofNo.186 to full working order in the RPS) workshops at Whitehead

Letter putting an Englishman to right! No. 189 destroyed by IRA activity was not built at the GS& WR 's works at Inchicore, but was one of a pair built by Beyer, Peacock, Manchester, Works No. 2029, and delivered to Inchicore on 18th April 1881. It was withdrawn in 1923 but it is not strictly true that it was the first of the 10I Class 0-6-0s to be scrapped There were eight of the class scrapped between 1885 and 1890, No's 103/105/110/111/114/118/147/149 and all were replaced with new locomotives of the same type carrying the same number. No. 189. was the first to be an unplanned scrapping.

200 class RNC XXXVI: 1902
Standard 101 class fitted with 44ft 4in diameter boiler (heating surface: tubes 925ft2, firebox, 116ft2 and grate19.3ft2) and modified cab. The same boiler was later fitted to many of the older 101 class locomotives and the two classes were amalgamated. No. 200 was introduced in February 1903 and was withdrawn in November 1960. A total of twelve locomotives were designated as being in this class.

Centres on Alexander McDonnell and how a series of standard locomotives were evolved for the major Irish railway (the Great Southern & Western Railway at its Inchicore Works, including the dominant 101 class of 0-6-0 (designed at Beyer Peacock), and eventually the Kerry bogies (4-4-0) which evolved from McDonnell's light 2-4-0 design. An 0-4-4BT (a sort of Fairlie) and an 0-6-4T are also considered. McDonnell was an inspired head hunter: the brilliant engineer John Aspinall was recruited from Webb to be Works Manager at Inchicore and later Ivatt was attracted across the water in the same manner. Thus it is shown how the Kerry bogie concept was to re-emerge on the LYR and GNR.

Most were rebuilt with Belpaire Type X boilers from the 1930s onwards, but two were withdrawn earlier (No. 53 in 1925 and No. 97 in 1930). No. 11 remained in its original state until withdrawn in 1949. Ahrons (Locomotive & train working) stated that design based on McDonnell's larger 2-4-0 but with his swing link bogie. They were intended for the Dublin to Cork mail trains. Clements, McMahon,& O'Rourke. pages 92-3 add considerably, but doot mention Type X Belpaire boilers.

The earlier series bhad 150 psi boilers, whereas the later ones had 160 psi, although this was subsequently reduced.Clements and McMahon pp. 84-5.Clements, McMahon,& O'Rourke. show that the boiler dimensions differed significantly between the three batches; there were also minor differences in length and coal capacity. The banked trains out of Cork; hauled freight from Cork to Rathpeacon and worked the Cork City Railway. Nos. 201, 207 and 209 had steam heating apparatus and may have worked passenger trains in West Cork, No, 297 retained its double smokeboc door until wthdrawal.

First Irish 4-6-0 and one was exhibited at the Dublin Exhibition in 1907.Clements and McMahon pp.121-2 note that may have been known as Long Toms, but there is doubt about this nickname. They had 5ft 1¾in coupled wheels, 19¼ x 26in cylinders, a grate area of 24.8ft2 and a total heating surface of 1600ft2. They were unpopular due to their rough riding and proneness to derailment due to the lightness of the front end. Withdrawal started in 1928 and the last (No. 366) was withdrawn in 1931.Chacksfield The Ceey/Cowie brothersdoes not conider it to be a good design and all had been withdrawn by 1931, most in 1928.

Retrospective
Clements, McMahon,& O'Rourke. pages 137-8 record the conversion 0f an 0-6-0 design prone to derailment into a 2-6-0 by the addition of a pony truck. Much of the information recorded in Clements and McMahon pp. 119-21 is repeated (wheter the line drawing of No. 356 and the photograph of No. 355 are repeats is not known. The basic dimensions were: 5ft 1¾in coupled wheels, 19 x 26in cylinders and 24.8ft2 grate area. All were originally fitted with round-top boilers with 1316ft2 tube and 132ft2 firebox heating surfaces. They were rebuilt with Belpaire boilers of three types: Class 368-type (1446ft2 tube and 138.5ft2 firebox heating surfaces); another saturated Belpaire type with 1498ft2 tube and 139ft2 firebox heating surfaces, and superheated Belpaire boilers: 1i80.5ft2 tube and 139ft2 firebox heating surfaces and 290ft2 superheater. Nos. 355 and 360 received the 368t type in 1914 and 1921 respectively: No. 355 was withdrawn in 1928. All were fitted with radial pony trucks, but No. 356 received a superheated boiler and was fitted with a Bissel truck in 1925. Nos. 357 to 361 were fitted with saturated Belpaire boilers which were later replaced by the superheated type which operated at 180psi. No. 357 was withdrawn in 1931 and reinstated in 1935. With the exception of No. 355 (as noted withdrawn in 1928) all were withdrawn between 1955 and 1960. The Bissel truck fitted locomotive was used on Dublin to Cork Night Mails. Nos. 356 and 357 weere fitted with automatic ash ejector systems in 1949. No. 356 was converted to turf (peat) burning in 1952. The 1948 assessment was that it was a very useful heavy goods engine, powerful and with a low axle load....

368 Class K4: 1909
Nos. 368-71 Similar to 355 Class, but with a greater gap between truck and leading coupled wheels. The basic dimensions were: 5ft 1¾in coupled wheels, 19 x 26in cylinders and 24.8ft2 grate area. All were originally fitted with round-top boilers with 1316ft2 tube and 132ft2 firebox heating surfaces. No. 371 was fitted with a saturated Belpaire boiler in 1923: this operated at 180 psi and had heating surfaces of 1416.5ft2 tubes and 138.5 firebox. Nos. 368 and 371 withdrawn in 1928; other two remained in service until 1957. They were fitted with superheaters and piston valves in 1934 and 1935: the dimensions of the Q-type boilers were: 1068ft2 tubes, 136.7ft2 firebox and 250ft2 superheater..

Similar to Class 301, but with a slightly larger boiler. .Initially used for express work, but relegated to secondary work from about 1910. No. 308 was fitted with a tapered boiler in 1904, but this was over-weight and led to the lightening of frames, running plates and dragboxes. The remaining locomotives were rebuilt in 1906.

Class 321 D2: 1904-6
Running numbers: 321-32. Clements and McMahon pp. 108-12 admit that this class, originally of twelve locomotives, had a complex career. As built they had saturated tapered boilers (total heating surface of 1428.9ft2), 6ft 7in coupled wheels; 18½in x 26in cylinders; grate area 23 ft2. Between 1919 and 1922 Nos. 327-32 were rebuilt with thicker, deeper frames and extended smokeboxes and the boiler pressure was increased to 170 psi from 160 psi. Nos. 321-3 received similarly modified frames between 1924 and 1930. All these modified locomotives (except No. 332) received saturated Belpaire W-type Belpaire boilers with 1355ft2 tubes 148ft2 firebox 22.5ft2 grate area operating at 180 psi from 1924.and most were superheated from 1930. Canopy cabs were fitted to most locomotives. Nos. 324 to 326 were withdrawn in 1927-8 ( Clements and McMahonspeculate this may have been shortage of frames). No. 332 was fitted with 8 inch piston valves and superheated Belpaire boiler (W-type boiler with superheater 1060ft2 tubes 148ft2 firebox 250ft2 superheater 22.5ft2 grate area ) in 1927 and reclassified as Class 332. The modifed locomotives lasted until 1955 or later (two lasted until 1960). The class had a reputation for fast running: in September 1917 No. 328 hauling four bogies and two six-wheelers weighing 137 tons on a Cork to Dublin train ran from passing Limerick Junction to Thurles at an average speed of 74 mile/h from whence the 85.25 miles to passing Islandbridge were run in 79 minutes. In 1928 No. 329 hauling a special ran the 107 miles from Limerick Junction to Kingsbridge in 104 minutes.
In 1928-9 Nos. 328-31 rebuilt with heavier frames and parallel Belpaire boiler
From 1932 Nos. 321-3 and 328-33 fitted with superheaters
Did well on express work and continued into late period. Banned from DSER section beyond Dun Laoghaire as Sandycove curve was too tight for the long coupled wheelbase

Class 333 D2: 1907-8
Clements, McMahon,& O'Rourke. pp 102-3, use the term mixed traffic to describe this class, a variant of the 321 class with taper boiler.

They had saturated tapered boilers :total heating surface of 1412ft2 and a grate area of 21.ft2 pressed to 160 psi. They were intended for the Cork to Rosslare service until displaced by the Woolwich moguls. Nos. 333-6 had conventional bogies, but Nos. 337-40 were fitted with bogies with outside frames and outside bearings to reduce the problem of overheating. but a change of lubricant in 1909 obviated this overheating. All were rebuilt with Belpaire parallel boilers from 1927. The first No. 338 was rebuilt with piston valves and a superheated boiler and redesignated Class 338 1927, and in 1945 was fitted with 17in diameter cylinders. Most received superheaters.

Waterford & Limerick Railway
Clements, McMahon,& O'Rourke. devote Chapter 8 to this railway which was absorbed by the Great Southern & Western in 1901. Prior to that it had strong ties with GWR. It had a long cross country railway which extended from Waterford to Limerick and then headed north enabling its trains to reach Sligo. Its mainline was long (over 200 miles), but trains were very few in number. Its best known locomotive engineer was Robinson, who later acquired fame on the Great Central, but he had been invited to Ireland by Henry Appleby.Hamilton Ellis _Midland Railway_p. 79 noted: There was once an Irish railway, the Waterford and Limerick, which was noteworthy for its numerous succession of locomotive engineers, and for the infallible frequency with which they were dismissed, asked to resign, or induced to tender resignation. The last Locomotive Superintendent was J.G. Robinson.. Subsequent modifications made by GSWR/GSR are included here.

It may have been owned by John Dickinson & Co, — contractors. It was advertised for sale at Neath. for £90 and acquired by the WLR for that plus £98 for repairs and regauging. . It was sent to Limerick where the rear side rods were removed to enable to cope with tight curves in the yards. About 1890 Robinson fitted it with a cab and sanding gear to enable it to work at Fenit Harbour where the Commissioners offered £1000 for it in 1899.

Maunsell designsMaunsell was responsible for only two designs whilst in charge at Inchicore: the sole member of the 341 classs of 4-4-0and the 257 class of 0-6-0. Seeletter from Jeremy Clements and Michael McMahon in Steam Wld, 2008 (248), 19 which corrects information provided in article byClarke in Issue 246 page 30. Both classes are covered in J.E. Chacksfield's Richard Maunsell: an engineering biography. It should be noted that the 4-4-0 incorporated a Belpaire firebox (this was a marked change from Coey's designs) and 9 inch piston valves from which it is not difficult to see how "Inchicore features" were translated to Ashford. Chacksfield notes that the 341 design was fully covered in Rly Engr, 1913, October.There were also plans for a three-cylinder 0-8-2T and a 4-4-2T. Maunsell was also responsible indirectly for the "Woolwich" (i.e. Woolwich Arsenal partially constructed) 2-6-0s acquired by the Midland Great Western and Great Southern Railways. As none of Maunsell's successors were responsible for this design it is considered below...

4-4-0
341 Class D1: 1913
Large express 4-4-0 locomotive design for which originated with Coey, but usually credited to Maunsell. It had 6ft 7in coupled wheels; 20 x 26in cylinders; a grate area of 24.8 ft2 and a total heating surface of 1520.8ft2 plus 335.1 ft2 of superheat. It was fitted with Walschaerts valve gear and named Sir William Goulding. It was restricted to the Dublin to Cork route by the Civil Engineer who was concerned about the high axle load of 19 tons 2 cwt. Although there were press reports which credited as being the first of a class it remained a single locomotive and was withdrawn in 1928. At some time the clinders were reduced in diameter to 19in. Clements and McMahonpage 116..

K1: 1925
These 2-6-0s were very similar to the N class of the Southern Railway, as they were built from N-type parts supplied by Woolwich Arsenal. They were originally intended for the Midland Great Western Railway. Clements and McMahon arre highly enthussiastic about the Class and consider the purchase to have been excellent value. Nock Irish steam page 146 observes that when new the locomotives were "the most powerful in Ireland surpassing Mr Bazin's 500 class mixed-traffic 4-6-0s.".
To accommodate the 5' 3" gauge, it was necessary to provide new frame stays, smokebox saddles, axles and exhaust pipe distance pieces. The footplate was widened by 6½in to 8ft 10½in and the distance between the cylinder centres was increased by a similar amount to 7ft 2½in. The cab dimensions remained unchanged, a feature that was to lead to criticism from footplate crews who found the interior cramped by Irish standards, and who also disliked the unfamiliar right-hand drive (except for those used to ex-MGWR locomotives).
Another shortcoming was rough riding as mileages built up after repairs, a characteristic that was not unusual with outside-cylindered moguls. However, this trait seems to have been more extreme with the Irish version than with the Southern Railway version and is attributed to the greater distance between the cylinders which exacerbated lateral movement, and whereas the mainland British locomotives had a very stiff frame construction resulting from stays consisting of horizontal flanged plates fitted top and bottom, a short-sighted economy was introduced into the Irish version through reliance on a single new horizontal flanged plate (obviously longer to accommodate the wider gauge) fitted approximately midway between top and bottom of the frames. Locomotives introduced to service as Classes N & U with the Southern Railway, at the same time as their Irish counterparts, increasingly suffered from fractured frames. Because they were expected to continue at work into the 1960s, a number were reframed and extensively rebuilt in the period 1955 to 1961 by British Railways..
The amount of power that these modestly-sized locomotives could generate was a pleasant surprise to footplatemen.
There was contention among locomotive crews about the competence of the type. They do not seem to have been overly popular on the ex-GSWR section, in the early years at least, but ex-MGWR crews were fulsome in their praise, stating that services over their section could not be maintained without them. These varying views might be attributed to pre-amalgamation rivalry as the Woolwich was considered an MGWR inspired type, and because of its 'foreign' origins. Other sources disputed that there had been any significant criticism, alleging that they were vital in helping meet the GSR's motive power demands.
The brake system followed the Ashford layout with a steam brake on the locomotive powered by two 7½in diameter steam cylinders below the footplate. The tender was equipped with vacuum brake, powered by a single cylinder mounted below the running plate at the front end. Concern was expressed about deficiency in brake power when working non-fitted goods trains and several runaways occurred including that of No 390 at Cork in 1939 and of No 394 (Class KIa) near Inchicore on an up goods in 1954. The worst runaway involved No 375 working a Bridgetown-Thurles beet train at Cahir in December 1955 which ended up on the bank of the River Suir, killing the driver and fireman. Braking problems were identified early on with the British locomotives leading to the fitting of an additional brake cylinder on the tender; similar modifications were never instituted in Ireland.
One definite operating disadvantage stemmed from the chimney top being lower than the cab, so that exhaust often obscured forward visibility. As a result, smoke could swirl around the footplate making them dirty engines to work and leaving footplate crews looking like chimney sweeps. On the Southern Railway, this was overcome by fitting smoke deflectors; despite several recommendations, this useful modification was never applied in Ireland. A further cause of discomfort was that while the original design had included lagging and clothing of the firebox backplate, this feature was not fitted (in common with Inchicore's standard practice) leading to very hot footplate conditions.
It should be remembered that the type was originally intended for freight work in the southeast of England so their continued employment on express passenger services was stretching their riding and steaming capacities. There are reports that they had to be thrashed to keep time with heavier express passenger trains. Apart from the problems with riding discussed above, steaming suffered as fuel quality deteriorated. The Swindon-inspired firebox did not take kindly to ovoids, slack and duff. in the CLE oilburning programme, all but four (and all the 6' 0" version described below) were converted, although not all actually worked in this condition.
The potential offered by fitting larger boilers (parallel in this case) was recognised by inclusion of several in the new boiler order that was cancelled as a result of the Milne Report (see Chapter 14). A substantial increase would have been achieved:

In view of the stresses imparted to the existing structure, frame renewal or strengthening would have seemed inevitable with a significant weight increase and concomitant reduction in route availability.
A further option allegedly proposed around this time was that the moguls should be rebuilt as 3-cylinder 4-6-0s with larger boilers, or with a smaller version to keep down overall weight. It is unclear whether this was a serious exercise or merely a flight of fancy but the idea seems to have had little merit. Rebuilding as a 4-6-0 would have involved creation of a virtually new locomotive with perhaps limited route availability,

Clements, McMahon,& O'Rourke. page 142. who state that popular on goods trains, secondary passenger trains and beet trains on Rosslare route. Nos. 261 and 262 were llast steam locomotives in sercice on CIE. They were the first locomotives on GSWR with superheaters and piston valves. Development of Class 351 (J9). Nos. 257-61 were fitted with Schmidt superheaters whilst remainder fitted with Inchicore modified superheaters. They had 19 x 26in cylinders; 5ft 1¾in coupled wheels, and 20.4ft2 grate areas. Those constructed in 1914 (under Watson) were fitted with snifting valves. The class was highly regarded being effective on freight and secondary passenger services. Locomotives had a staccato exhaust and were in demand for seasonal beet trains overr the difficult Rosslare route. Most rebuilt with Belpaire boilers with a slightly reduced grate area (19.5 ft2).Clements and McMahon pp. 93-4.Clements, McMahon,& O'Rourke include a side elevation drawing of No. 262 and a photograph of No. 257.

B2 (400):
E.A. Watson introduced this class of ten locomotives soon after his arrival from Swindon in 1913. They were constructed as four-cylinder engines and, therefore, reflected Churchward practice to some extent. Four were built at Inchicore: No. 400 in 1916; Nos 402, 403 and 406 in 1921; and the remainder at Armstrong Whitworth in 1923: WN 185-190, but the running numbers did not mirror the works numbers. They were not successful, however, and Watson's successors inherited the task of improving them. Shortage of capital did not permit the locomotives to be rebuilt as a unit and modifications, of several kinds, took place over many years. Clements and McMahon pp. 233-44 cover this troubled design at length, including the many modifications made by Watson's successors. The table is a modified version of that provided in Clements and McMahon and may assist in disambiguating some of the contemporary references listed.

All had 6ft 7in coupled wheels and (until rebuilt) four 14 x 26in cylinders with 8in diameter piston valves. All retained 28ft2 grates. The tube areas varied, mainly in association with superheating.
¶ ordered as saturated engines

Clements, McMahon,& O'Rourke. page 106. record that "Influenced by the impressive performance of theGWR Star Class, Watson opted for 4-cylinder divided drive and in so doing added to the list of 4-cylinder 4-6-0 types that proved below par on these islands. Only the GWR mastered the concept with unqualified success, and Class 400 proved one of the more unsatisfactory examples of the genre. Several faults were attributed to the class but RN Clernents maintained that the root cause lay in poor design and weak frames. Adoption of outside motion was ostensibly an advance on the practice of placing this equipment between the frames. However, the greater distance between the sets of valve motion accentuated fore-aft lateral stresses on the frames at their weakest point where sections were cut away to accommodate bogie and wheels. This factor was recognised with the Stars which had thicker plate frames and substantially stronger cross-bracing in the cylinder area."
Evidently aat the design stage the LNWR Bowen Cooke Clughton desin was considered, but did not advance very far. [KPJ wonders whether any consideration was given to the Great Eastern inside cylinder 1500 design which was both fast and capable of traversing lightly built lines]
Very interestingly, Joynt, the chief draughtsman, is blamed for the asthmatic front end dimensions: interesting in that Joynt contributed much to Irish railway literature.

Clements and McMahonmake several statements about this controvertial class, notably that the frame thickness of No. 400 was 1/8in less than that used at Swindon for the Star class, but suggest that later Inchicore built locomotives had stronger frames. The Watson design suffered from short travel valves and Schmidt wide-type single piston rings (the cause of trouible on the LMS Royal Scot class). The steam pipes were badly designed, and an attempt to improve the layout with external pipes on No. 407 must have led to considerable heat loss (page 238: illustrated page 237). There is a suggestion that the Armstrong Whitworth locomotives may have been badly built: "on 3 June 1927, the Board had authorised investigation of legal action in respect of the failure of driving wheel tyres on all the Armstrong Whitworth built engines.". They also include at least one modification which did not appear to be reported at the time.

No. 402 was rebuilt as a 2-cylinder engine with Walschaerts valve gear. Clements and McMahon (page 238 et seq) state that a full set of drawings was passed to Maunsell with a plea for advice who requested Holcroft to investigate. He advocated rebuilding with two cylinders (19½ x 28in) with 10in long lap piston valves. This led to a successful, faster and more economical locomotive...

1930 Morton: Beardmore-Caprotti valve gear
Nos. 401 and 406 were rebuilt as 2-cylinder engines similar to No. 402, but with Caprotti valve gear.Clements and McMahon pp. 241-2 observe that the rebuilt locomotives were competent and economical and that the valve gear proved remarkably durable, retaining most of its original parts. Note the performance of No. 401 when it hauled a load of 375 tons from Portlaoise to Dublin at an average speed of 58.7 mile/h. They do, however, question the capital economics: £14,000 (or the equivalent of seven Mogul kits), but suggest that Beardmore may have offset some of the cost (and KPJ Woolwich sets may not have been available). ..

Retrospective and critical
Clements, Jeremy andMcMahon, Michael. Locomotives of the GSR.
It is realised that this remarkable work is cited throughout this web page, but in the case of the 400 Class the section relating to this Class almost becomes a monograph, There are so many puzzles: why order saturated locomotives so late in the day. The Armstrong Whitworth lcomotives had laminated springs on all axles connected by compnsaating levers whereas the Inchicore-built locomotives had helical springs on the centre coupled axle. They were generally sluggish and had a feocious appetite for coal. The two-cylinder 500 Class completely outperformed them. Steam pipe fractures were a major problem. Bazin sent a set of drawings to Maunsell for his assistance and thse were passed to Holcroft who recommended the two-cylinder layout.
Cliffe, Joseph. Just add more cylinders. Backtrack, 2013, 27, 381.
R.N. Clements, the doyen of Irish railway writers, opined to Cliffe that perhaps all the '400s' really needed was thicker frames like the GW 'Stars'. The three saturated examples were built by Bazin because after the troublesome Watson superheater there was no suitable replacement then available. Bazin returned to the Maunsell-type superheater on the '500s', which the initial '400' also did have. In truth the GSR did not really need ten express 4-6-0s and three were scrapped early.

4-8-0T

900 Class A1: Watson design
No. 900 was built in 1915 and withdrawn in 1928. No. 901 was built in 1924 and withdrawn in 1931.
Maunsell had schemed a three-cylinder 0-8-2T shunting locomotive for Kingsbridge, but there were problems with design of a derived gear for the inside cylinder. Notes that in 1919 Maunsell had planned a three-cylinder 2-8-0T with 4ft 8in coupled wheels and Holcroft valve gear for the SECR and this design received Board approval, but was not constructed.
The 900 Class employed the bogie and cylinders of vthe 362 Class and the cylinders drove the leading coupled axle. They were prone to derailment and latterly No. 900 ran as a 4-6-2T. they were used to bank goods trains from Kingsbridge to Inchicore. Clements and McMahon pp. 124-5

The heaviest GS&WR locomotives were two 900 class 4-8-0Ts, designed by Watson and weighing 81 tons. The first entered service in 1915 for shunting and banking, while the second appeared in 1924. It was later found that their duties could be carried out by the more economical standard engines and both were scrapped by 1930.

Bazin designs

B1 (500):1924: Bazin:
This was a mixed-traffic 4-6-0 design with 5 ft 8½ in driving wheels. They were successful in service and capable of working express trains.Clements and McMahon (pp. 255-6) make several statements about influences on the design including those from Maunsell via the Urie/Maunsell designs of the Southern Railway and from Gresley at Doncaster. Bazin was a member of the ARLE and was active in the Institution of Locomotive Engineers. They rightly state that this was the first manifestation of the simple two cylinder 4-6-0 with external Walschaerts valve geart outside of the Southern Railway in the British Isles. The leading dimensions were 5ft 8½in coupled wheels; 19½ x 28in cylinders; a 28ft2 grate; 1590ft2 tubes, 158ft2 firebox and 350ft2superheater. The valve travel was 63/16 with 1½in ;ap. They were fitted with Schmidt wide-type single piston rings. The 1948 assessment was critical of the small diameter driving wheels which made them unsuitable for passenger work. One was constructed in 1924 and two in 1926. They were withdrawn between 1955 and 1957...

2-6-2T

P1: (850 Class): 1928: Bazin :
This was a solitary locomotive (No. 850). Clements and McMahon (pp. 259-62) note that the lightweight motion was the Achilles heel of the design (it tended to run hot), and the problem was mitigated by its replacement by heavier components. The locomotive tended to roll at speed. They also note that parts may have come the Woolwich moguls, notably the pony truck and driving wheels. The main dimensions were: 5ft 6in coupled wheels, 17½in x 26in cylinders with 8in piston valves, 19.75ft2 grate area; and heating surfaces of 697 tubes, 119 firebox and 240 superheater. It carried 3 tons of coal and 1700 gallons of water. Clements and McMahon suggest that the design may have influenced that of the Gresley 2-6-2T (V1 class), but KPJ considers that the Inchicore locomotive was highly Doncaster-influenced. No. 850 was used on the Dublin to Bray route, but was also tested between Dublin and Thurles and between Waterford and Limerick. The dust jacket includes a reproduction of a painting of this magnificent-looking locomotive. Nock's Irish steam(page 147) notes that the type might have been intended to work on the Cork, Bandon and South Coast section. ..

Alternative designs considered (inside cylinder 2-6-2T and outside cylinder 4-4-2T)
Notes in the prefatory paragraphs in Clements and McMahon (page. 259) that initially the GSR had hoped to withdraw the entire DSER fleet and considered a 2-6-2T design (with 5ft 1¾in coupled wheels, 17 x 26in cylinders, probably inside, and 18.8ft2grate areaa , 938ft2 tube and 112.5ft2 firebox heating surfaces). On 20 February 1925 the Locomotive, Permanent Way & Works Committee were shown the proposed Class 380 4-4-2T planned for the Dublin suburban services. This had outside cylinders and Walschaerts valve gear and employed the standard N-type Belpaire boiler: the main dimensions were: 5ft 8½in coupled wheels,. 17½in x 28in cylinders, 19.5ft2 grate areaa, 708ft2 tube, 120ft2firebox and 168ft2 superheater heating surfaces.

0-6-0
Class 700 J15A: 1929
Five highly conservative (saturated boilers and slide valves) were constructed possibly to exploit Clements and McMahon (pp. 263-4) eight new Type 60/101 boilers built in 1924/5. Their leading dimensions were 5ft 1¾in coupled wheels, 18 x 24in cylinders, 19.1ft2 grate areaa , 887ft2 tube and 126ft2firebox heating surfaces. They were never superheated and according toClements and McMahon were unpopular with footplate cres, suffered from high coal consumption and were inferior to the superheated 101 Class 0-6-0s. Withdrawn bewteen 1955 and 1963.. .

Sentinel purchases
Sentinel locomotives and railcars were purchased during Bazin's tenure, and probably reflect his close ties with Gresley and with the Institution of Locomotive Engineers where the designs were discussed.

GSR Class 280 M1
WN 6846-7/1927. RN 280-1. 2ft 6in driving wheels (chain coupled). 6¾ x 9in cylinders; 5.1ft2grate area and 71ft2 total heating surface. They had several braking systems: steam, hand, counter pressure and vacuum and were very similar to the Sentinel railcars.Clements and McMahon (pp. 257-8). They were sent initially to Cork and Tralee, and one was tried on the Castleisland branch. They both were then sent to Limerick where they worked the Market siding until in closed in 1940. They then remained out of use until withdrawn in 1948

Steam railcars
Policy was very similar to that on the LNER. Both the moderately successful Sentinel Waggon and disastrous Clayton products were acquired. Clements and McMahon (page 299 et seq

Sentinel
These received Nos. 354-7 in the coaching stock list and were WN 6844-5 and 6912-13, but there was probably no correspondence between the two numerical series. The engine units were similar, but the boilers were larger, than those on the shunting units: 2ft 6in driving wheels (chain coupled). 6¾ x 9in cylinders; 18ft2 grate area stated to give 100hp. They were articulated, like the earlier LNER units, and the bodies were supplied by Metro-Cammell of Nottingham and conveyed 55 passengers. Vacuum pipes were not fitted, and trailers could not be hauled. They were withdrawn in 1941-2. They were tried on the Goold's Cross to Cashel branch where the unsuccessful GSWR No.1 steam railcar had been tried in 1904, the Foynes and Newmarket branches and between Limerick and Nenagh and Ballybrophy.An unusual working was the attachment of a railcar, Sentinel or Clayton to the 11.10 departure from Mullingar to Cavan as far as Inny Junction whre it was detached and worked on to Sligo. There was a return working on the following day. The livery was a dark purple brown. They lay out of use for two to three years at Waterford before being scrapped The withdrawal date is given as 1941/2. .Clements and McMahon pp. 300-1.See also Sentinel railcars page.

Clayton Wagons cars
Clayton Wagons of Lincoln entered the railcar business after Sentinel and competed on price (£1800 per car). Cars Nos. 358-63 (coaching stock numbers) were acquired in 1928 and had been withdrawn by 1932. The seating included nine seats for first class passengers and accommodation for 55 third class. Firemen found the stoking tube to be very awkward. Some were evaluated on Dublin Westland Row to Dalkey services and on Harcourt Streeet to Foxrock services. They were also tried between Mullingar and Sligo and on the Cork to Macroom and Clonakilty services. Steaming was bad and the cars were unreliable mechanically. Clayton had claimed a coal consumption of 11 lbs per mile, but this extended to 19 to 25 in practice. Liquidation of Clayton in 1929 aggravated the problems. The carriage units were converted into articulated pairs and were exploited, presumably as a form of penance, during the Dublin Eucharistic Congress. They then formed the carriage stock on the Waterford & Tramore section until displaced by diesel railcars in 1955. . .Clements and McMahon pp. 301-3.See also Clayton railcars page.

Retrospective
Derived from Class 333/338. Clements and McMahon (pp. 269-70) skeptical of overall GSR locomotive policy which had seen three class 321 withdrawn in 1927-8 whilst other members had received new boilers and stregthened frames. It is argued that the outide frames and bearings were fitted to the bogies to avoid overheating of the axle journals, but that this problem had been solved by a change in lubricant.
No. 346 was fitted with Hoffman roller bearing axleboxes on its bogie wheels.
Nos. 344 and 346 were fitted with 17in diameter cylinders in about 1940.
Before 1939 concentrated on services south of Dublin, but under CIE worked Dublin to Waterford/Rosslare, and on MGWR section to Sligo, Westport and occasionally to Galway.
No. 347 was lent to the GNR(I) to work the Bundoran Express between Dublin and Dundalk. No. 346 was an oil-burner at this time. Withdrawn 1959/60..

Retrospective
Clements and McMahon (pp. 266-7) Survived until withdrawn 1959 to 1962. Used on Dublin to Bray and Greystones suburban services. Standard components included Z-type boiler and running gear from 710 Class. The inside motion was difficult to access. In spite of the archaic appearance the superstructure was welded. Cast iron number plates were replaced in favour of large painted numerals. From 1948 they were painted in green passenger livery.

Bredin designs

4-6-0

800:1939 B1a
By a large margin, the three locomotives were the biggest and most powerful engines ever to run in Ireland. Further, it was the only design which exploited the extra width afforded by the 5 ft 3 in gauge. The engines had 6ft 7in coupled wheels, three 18½ in x 28 in cylinders and 225 lb/in2 boiler pressure (later reduced to 180 psi): the heating surfaces were: grate area 33.5ft2, tubes 1670ft2, firebox 200ft2 and superheater 468ft2. The tender was very large by Irish standards with a capcity for 8 tons of coal and 5000 gallons of water. The nominal tractive effort was 34 799 lbf, which corresponded with Great British main-line power. They were intended for the Dublin-Cork route and received the names of ancient mythological Irish ladies of substance (sometimes known as queens): Maedhbh, Macha and Tailte. The nameplates had Erse characters. Clements and McMahon have assembled a highly comprehensive description which can be criticised for over-stating the novelty of double chimneys (eleswhere the Kylchap had been applied, notably on the LNER) and it is doubtful if the separate exhausts employed at Inchicore really represented an advance. Influences considerd byClements and McMahon include Chapelon (in the design of the internal steam passages) and Maunsell who is known to have visited Inchicore following his retirement. The boiler was of the parallel type with tapering on the cladding. They suggest an enlarged Schools class as the inspiration. They are remain skeptical whether such a large locomotive could be justified, although they do accept that National prestige was a positive factor. They cost £12,000 each. Clements and McMahon consider that five locomotives were probably contemplated, when the design was being planned. The CIE failed to exploit the locomotives which achieved very low mileages compared with the King and rebuilt Scot classes. Furthermore, they could burn low grade fuel. The MeLeSco superheater was "advanced" at the time and is usually associated with post-War locomotive development in Mainland Britain.Clements and McMahon consider that the locomotives were the equal of the rebuilt Scots and better than the Kings..
Phil Atkins (e-mail to KPJ) records that H J.A. Beaumont was chief draughtsman at Inchicore when the 800s were being designed. He has inspected a copy of a 1937 diagram for a proposed Inchicore 'Pacific' which would have much as the 4-6-0 later built but with a carrying axle tucked close behind Argentine-fashion, with a rather unpleasant streamlined cowl round the single chimney. Presumably, a Pacific was even more prestigeous, but adequate turntables were impossible to justify!..

Pp. 271-7 form the main section for a description and assessment of these three remarkable locomotives, but the locomotives are also considered elsewhere in this work. There is Appendix J (page 379) which describes the attractive names which stem from Irish mythology, and are sometimes incorrectly stated to be "queens". There is a tantalising reference to a "visit by senior locomotive engineers from the LMS in 1940" and that "No. 801 was placed at their disposal": such a visit does not appear to be mentioned either by Bond or by Cox even they were "lavish in their praise" for its speed and haulage capacity...

Undoubtedly the finest locomotives to emerge from Inchicore were the three 800 class 4-6-0 express passenger engines built in 1939 to the design of E.C. Bredin, and named Maedhbh, Macha and Taille. Costing £13,000 each, these were the most powerful express engines ever to run in Ireland and had three cylinders 18½in by 28in, while the driving wheels were 6ft 7in in diameter. The total weight of locomotive and tender in working order was 135 tons and the overall length 67ft 9in. During the War the 800s were frequently seen hauling as many as twenty carriages of varying sizes between Dublin and Cork.

Fuel shortage during WW2
This is covered in Clements and McMahon Chapter 13: as someone disciplined by the Penny Catechism KPJ hopes that the Authors are performing some Celtic penance barefoot for allocating this number to this subject. During WW2 Southern Ireland suffered from a chronic shortage of fuel and this was most accute in 1941 when train services had to be greatly reduced and journey times became protracted. There were attempts to burn peat and to mix cement with coal dust, but these were largely failures. In the immediate post-War period oil-burning was adopted on quite a large scale, but the rapid change to diesel traction was the most lasting influence. J.H. Dudley, Assistant Locomotive Running Superintendent to the CIE described some of his work on this subject in a paper to the IRRS (and as transcribed in Chapter 13).

Boilers
Clements and McMahon Appendix C1: The GSR programme to modernise the constituent companies' locomotive fleets focused on replacement of time-expired boilers. There was already considerable variety among the boilers acquired in 1925 and while the concept of standardisation might have seemed attractive, limited progress to this end was achieved in the next 20 years. A system of boiler types was introduced, mainly identified by a single letter although some were known by the GSR Class designation with which they were originally associated. Several of the boiler types were used with a single locomotive class, but two types in particular – N and Z – were fitted to several different classes of varying vintages. It was significant that both types were parallel boilers with Belpaire fireboxes and superheaters: after the Bazin hiatus of 1925-1929, there was a determined effort to introduce modernity with enhanced efficiency. Nonetheless, older saturated types with round-topped fireboxes lasted well into the 1950s.
The policy of retiring boilers on an age basis alone was criticised in theMilne Report. The inference is that the possibility of an old boiler still having years of potential operating life was discounted at the time of withdrawal. By this process, changes of boilers or of boiler types occurred more frequently than might have otherwise been necessary. It was notable that changes in boiler type could persist well into old age, as graphically illustrated with the 19 surviving members of 2-4-0 Class 650 (G2). At the creation of CIE in 1945, the programme of boiler changes which had started in the early 1920s continued unabated. As at 1 January 1945, these locomotives were aged between 48 and 51 years yet 14 more changes of boiler type were to occur, the last being as late as 1959. Pursuit of improved performance would not have been a significant criterion by that stage so replacements would have been implemented to make use of whatever was in stock and serviceable at the time. As will have been observed in the individual class histories, some later boiler changes were regressive and of doubtful value. The Bandon 4-6-0Ts, already sound performers, were improved by installation of Type R boilers. Only five of the class were so fitted; two later reverted to round-topped saturated boilers although one of these did return to a Type R after two years.
Sometimes the number and variety of changes seemed bewildering. During the period 1932 to 1951, Class 455 (C2) carried six different boiler types and underwent seven different boiler changes. As this class comprised a mere three locomotives, this programme must have achieved some sort of record.
Another case of regression involved Classes 400 and 500 which originally shared the same boiler. Later, six of the surviving 400s received larger K type boilers, but three of these were carrying original type boilers at withdrawal. In view of the comparatively modest haulage demands made of this class during the 1930s, the excursion into larger boilers must have been an exercise offering a minimal financial return.
The heating surfaces quoted for the original Class 400 boilers identify a further complication. The class prototype (No 400) and the three Armstrong Whitworth superheated locomotives (Nos 403-05) shared the same heating surface areas yet the Inchicore trio (Nos 401, 402 and 406) had smaller tube areas. Variations in tube areas resulted from use of differing numbers of small tubes, easily effected by replacement of boiler tube plates. This is the most likely explanation why the heating surfaces quoted in the table in this Appendix sometimes differ from heating surfaces for the same type of boiler recorded in some of the class histories.
In several instances the differences in quoted heating surfaces are quite small and would have had little or no impact on steaming capacity. Presumably these variations, as with a number of the boiler changes, came about through monetary shortages and the necessity of using whatever suitable material was on hand.
Another difficulty lies in photographic evidence that is at odds with recorded details in class histories. For example, locomotive No 403 reportedly received a Type K boiler in 1936 which it carried until withdrawal in 1957. However a photograph shows this locomotive in CIE lined green livery and carrying an original type, smaller boiler. The inevitable conclusion is that even more changes of type (let alone of heating surfaces) took place than were actually recorded.
Finally, reported boiler dimensions can vary between classes that ostensibly carried the same type.
Nock page 195 observes that the K class boiler was of the sloping throat type. This feature of boiler design (which appears to have generated a growing literature retrospectively) does not appear to be mentioned byClements and McMahon . Moreover, it is probable that the 800 class also incorporated boilers of this type, and possibly those introduced by Bazin.

Tenders
Clements and McMahon Chapter 11 (pp. 279-97. Also considers water sofening plant (only one and that at Inchicore). Water troughs were considered, but difficult to find a suitable location combining good quality water with level track. Tenders were recycled as on other railways: the GSR built 49 tender locomotives, yet built only 34 tenders.

Coras Iompair Eireann

O.V.S. Bulleid, formerly C.M.E. of the Southern Railway, became a consultant to the C.I.E. in 1949 and later assumed the full responsibility of being CME. In Ireland, Bulleid adopted a vigorous dieselisation policy and the use of steam traction rapidly declined. Nevertheless, one experimental steam locomotive was constructed; namely a turf, or oil, burning 0-6-6-0. This was similar to the Southern "Leader" class in many respects, but the new design wias simpler to build. In connection with this attempt to burn turf (i.e. peat), one 2-6-0 was also modified.

Milne, Sir James.Report on transport in Ireland.
Clements and McMahon present a digest of this significant report on pp. 329-35. They note O.V.S. Bulleid's in the study presented to the Minister for Industry & Commerce, but sadly fail to name the other two GWR ex-officers involved in the study. They do note, however, the GWR policy of standardization. As the ex General Manager of the GWR the report may also show the way in which he might have steered the GWR, and more significantly, the direction that British Railways might have taken if he had accepted the post as Chairman of the Railway Executive.KPJ wonders if James Ness, GM of the Scottish Region was influenced by Milne: he certainly advocated shorter, faster and more frequent trains, but hauled by large steam locomotives. It is also tempting to wonder what Milne's paradigm locomotive might have been like: perhaps Robin Barnes' Hawksworth 4-4-0 on pp. 78-9. The most significant observations are noted below:
On 1 January 1948 there were 418 broad gauge locomotives: Milne considered that only 233 were needed.
More intensive maintanance of narrow gauge fleet to reduce its total stock.
Condemned the 37 boiler types, when the GWR had only 15 types for 2000 locomotives.
Milne considered the Inchicore boiler policy to be unsound and extravagant.
Criticised lack of water treatment policy.
Three or four classes with a maximum axle load of 16 tons could handle all traffic except for shunting. All the 4-6-0s should be withdrawn.
A more intensive Dublin to Cork service should be operated with short trains
Diesel railcars were favoured, but not diesel locomotives as they were too expensive.
Steam locomotives hauling six coaches could perform as well as diesel lcomotives.
The existing orders for diesel locomotives should be cancelled.
Clements and McMahon note that most of the Report was not implemented, although most passenger services were worked by diesel railcars.
