LNER locomotive types

2-8-2

P1:1925
The P1 type was developed from the Al Pacific design for the haulage of heavy freight trains on the Great Northern main-line. The boilers and cylinders were interchangeable between the two types, but the 2-8-2s had smaller, 5 ft 2 in, driving wheels. The nominal tractive effort was 38,500 lbf, to which a further 9000 lbf could be added from a booster which acted on the trailing wheels. The class was introduced at the same time as the Ul Beyer Garratt and the types were available for the Stockton & Darlington Centenary celebration. Most contemporary references consider the designs simultaneously.

P2 class:
This class was introduced for the haulage of 550-ton passenger trains between Edinburgh and Aberdeen without recourse to double-heading. On the basis of tractive effort (43,462 lbf) the locomotives were the most powerful passenger engines in Britain. There has been a considerable amount of discussion on the efficacy of the design, and this aspect is considered with the retrospective material. The design was the first in Britain to incorporate many of Chapelon's ideas. Although there are colour photographs of several A4s in a variety of liveries there appears to be no colour photograph of a P2, but there is an excellent Vic Welch painting (Nock: Scottish railways).

P2/1 :1934:
No. 2001 Cock o' the North was the first of the class to be built. It differed from the five subsequent locomotives in being fitted with Lentz rotary cam valve gear. Many of the extensive contempoary references also describe a test run from London to Barkston, near Grantham, with a 650- ton train : 2090 drawbar horsepower was recorded on the climb to Stoke Summit.

P2/2:1934:
The four locomotives of this sub-class differed from No. 2001 in being built with Walschaerts-Gresley valve gear. No. 2002 was fitted with a modified form of the streamlining which clad the prototype, but Nos. 2003 et seq were built with the A4-type wedge-shaped front-end. Subsequently Nos. 2001 and 2002 were rebuilt to conform with Nos. 2003 et seq. No. 2006 (P2/3) was built with a combustion chamber, but this is not mentioned in contemporary sources.

Retrospective and critical
A controversy has arisen about the efficiency of the design. This has partly resulted from Thompson's drastic rebuilding of the class is Pacifics (see A2/2), which implied official condemnation. McKilliop, who drove the locomotives in service and on tests, was critical of the poor riding qualities and high coal consumption. It should be noted that McKillop usually praised Gresley designs, especially the Pacifics. C.J. Allen has disagreed with McKillop, however, (see "Ponies, Pacifics and mikados") basing his argument in terms of performance and power output. O.V.S. Bulleid also had a high regard for the design and was closely associated with the tests performed at the Vitry testing station, near Paris. Geoffrey Lund gave an excellent account of the class in a special issue of Backtrack devoted to the LNER.

Bellwood and Jenkinson (presumably the former) summarized P2 performance: There were insufficient passenger trains loaded to over 500 tons on the Aberdeen route to utilise fully the six locomotives, with the result that many workings were 'over-engined'. The eight-coupled axleboxes did not take kindly to the numerous curves on the route, and with Pacific train loads the P2s were expensive to both operate and maintain.
It is a great pity that their prodigious haulage capacity could not have been used to assist in the working of the enormous wartime loads between Kings Cross and Newcastle. Certainly there would have been ample opportunity for them to be run under near optimum operating, if not maintenance, conditions in relation to power output and adhesion. However, it was not to be. There was no place for Gresley 'super-power~ in the strategy of the new CME and all the P2 class locomotives were rebuilt by Thompson into ungainly Pacifics. As 4-6-2s, they had a very short life on the Aberdeen. road and had all been scrapped before the end of 1961.
Whatever the merits or shortcomings of Cock o'the North, it probably represented Gresley's greatest single step forward and was certainly ahead of its time. It is significant that when, twenty years later, the last express passenger steam locomotive was built for British Railways, it had three cylinders fitted with poppet valves.

Author was a technical assistant at the Scottish Area headquarters (posthumous contribution) at the time when the P2 class was being considered for desconstruction into Pacifics. The main problem at that time was poor workmanship at Cowlairs which led to problems with the superheaters which did not disappear after the conversion into inferior Pacifics. Lund is critical of McKillop's assessment of the P2 class. He mentions that the W1 was sent to Scotland by Thompson to assess the sutability of a large-boilered six-coupled locomotive to handle the Aberdeen sleeper traffic. It appears that E.D. Trask tried to halt the rebuild.

4-6-2

A4 class

Introduced 1935: The A4 design was based on the earlier A3 class, but the boiler pressure was increased to 250 lb/in2 and the steam passages were redesigned ensure maximum flow. Externally this class differed considerably, as it was streamlined for hauling the high speed Silver Jubilee train, which was introduced concurrently. During the press debut on September 27th 1935, a speed of 112½ mile/h was attained. Most of the contemporary descriptions refer to this high speed run, the streamlined train-set and the locomotive, but the last sometimes receives least attention. Later No. 4468 Mallard raised the speed ceiling to 126 mile/h, a world record for steam traction.

Testing and performance
C.J. Allen stated that every trip in one of the A4-hauled, streamlined trains was a special occasion and this is reflected in the many references to general performance, in terms of reliability, coal consumption etc. Further, no other class of British steam locomotive has been deliberately driven at high speed for record making purposes on so many occasiosn or at such high speeds.

7 September 1948: Non-stop journey of 408½ miles:
Flood damage between Edinburgh and Berwick necessitated that the "non-stop" "Flying Scotsman" be diverted via Galashiels and Tweedsmouth. Normally stops were required, on the diversion, for banking assistance and water, but on one occasion Driver Swan decided to scorn these and make a genuine non-stop journey. This showed that the locomotives were very economical in fuel and water consumption. Others followed and this has led to more controversy and extra-information in 21st century

Part 1 began on page 275. The service was restored on 31 May 1948 with a timing of 7h 50 min. The line between Edinburgh and Berwick was breached on 12 August. The northbound service took 16 hours on that day, which put it in the Virgin class. Initially the southbound route was via Beattock, Carlisle and Leeds, but we were the first south-bound "non-stop" over the Waverley route to Carlisle and some of the progress was very slow.. The St Boswells to Tweedsmouth route was reopened on 23 August, but Lucker troughs were now 92 miles from Edinburgh, but on 24 August Bill Stevenson with 60029 Woodcock managed to lift the train to Falahill without a banker and start the non-stop run to King's Cross of 408.6 miles - a world record, repeated subsequently in both directions on each of eight occasions. See letter by A.J. Mullay (p. 474) which adds another long way round non-stop, additional info by Farr.

2-6-2

V2 class

The V2 class was evolved from the A3 Pacific design, but there were several changes in the basic dimensions, other than the obvious one of wheel arrangement. The major changes were as follows (the figures for the A3 types are shown in parentheses) : coupled wheel diameter, 6 ft 2 in (6 ft 8 in); cylinder diameter, 18½ in (19 in); length of boiler barrel 17 ft (19 ft); and total length of engine and tender, 66 ft 5 in (70 ft 5 in). Although these figures show a general reduction in size, nevertheless the grate area (41 ¼ft2) was identical in the two classes and the nominal tractive effort of the V2 type was, in fact, slightly higher. The new class was, therefore, capable of hauling all, but the very fastest or heaviest, main-line trains. 184 locomotives were eventually bailt.
Later the concept of large mixed traffic locomotives was developed by Gresley's successors and by Bulleid on the Southern and by Riddles for British Railways. These later designs were Pacifics, however. There is some indication (see Watts and Wilson retrospective and critical material) that the leading pony track was inherently unstable.

V4: 1941:
Gresley's final design was this class of two mixed-traffic locomotives. Most of the contemporary accounts compare it with the V2 type as the classes share the same wheel arrangement and wide firebox/three-cylinder design concepts. The V4 was much smaller in all dimensions, however. The maximum axle-load of 17 tons permitted a high route availability.

4-6-0

B17:1928
The bridges on the Great Eastern Section had been very lightly constructed and a severe axle-load limit was in operation. Further, the small turntables limited locomotive length. Until 1928 the largest locomotives per mitted were the Holden B12 4-6-0s, which had an adhesion weight of 44 tons. To supplement these light locomotives Gresley introduced his B17 class, in which the use of three cylinders permitted the adhesion weight to be raised to 54 tons. The nominal tractive effort of the new design was 25,280 lbf, which represented an increase of 3,411 lbf compared with the earlier 4-6-0s. The first batch was built by the North British Locomotive Co. and H.A.V. Bulleid (Master builders of steam p. 61) has stated that this Company undertook the detailed design work.

Performance

Nock's British steam locomotives at work. 1967.).quotes a log he had made on the Marylebone to Nottinham newspaper train: "So far everything had gone swimmingly on the footplate; the engine was steaming freely; all was sweet and true at the front-end, and the long continued use of a short cut-off naturally resulted in economical working, even though the booked speeds were so high. When the regulator was full open the steam chest pressure was within 10 lb. per sq. in. of the boiler pressure. And then to conclude Gayton Hall and her crew treated me to a perfect little classic in the way of locomotive running, between Rugby and Leicester. In starting away the engine was put to it hard for the first six miles; she certainly responded in full measure, with an acceleration to 66 m.p.h. in 1« miles from the start, and in mounting the Shawell bank at 57« m.p.h. Then, with cut-off back to the 15 per cent position once more, came the climax of the whole journey. A very rapid acceleration from Ashby led up to a maximum speed of 90 m.p.h. at Whetstone. The engine developed this effort with the utmost ease, the regulator being no more than two-fifths open and steam chest pressure only 110 lb. per sq. in. Finishing in characteristic style, with top speed maintained to the very last minute, we made the run from Rugby to Leicester in a full minute under the 20 min. scheduled for this 19.9 miles.

This run afforded a perfect exposition of the functioning of the Gresley front-end. Sir Nigel Gresley designed his engines so that they could do the work on a short cut-off, and one rarely, if ever, saw one of his three-cylinder types pounded on a heavy bank. Driver Simpson took things quite easily on the climb to Amersham, and precisely the same methods were adopted when the new 'Sandringhams' of the 'Football Club' series arrived on the Great Central section. Never, I should imagine, has a group of top-link drivers taken more readily to a new class than the Leicester men did to Arsenal and her colleagues; these new engines required totally different methods of handling from those long practised on the Robinson Atlantics, but from the outset they received the right treatment. After all there cannot be a much simpler engine to drive than one which can be opened straight out to full regulator, and which will do nearly all its work on a nominal 15 per cent cut-off.

4-4-0

D49: 1927 :
This class was introduced for working secondary express duties on the Scottish and North Eastern Sections. Three 17 in x 26 in cylinder were incorporated, but the boiler was standard with class J39. In consequence, the total heating surface was restricted to 1669 ft2 and the grate area to 26 ft2. Comparative figures for the B17 and Southern Schools classes were 2020 ft2 (2049 ft2) and 27'/2 ft2 (28.3 ft2) (the figures for the Schools class are within parentheses). The capacity of the locomotives was, therefore, limited, but O.S. Nock (The locomotives of Sir Nigel Gresley pp. 724) has described one run on which 1230 drawbar horsepower was achieved whilst hauling 435 tons.
The original design was fitted with Gresley derived valve gear and was known as the D49/1 or Shire class. In 1928, Lentz oscillating cam valve gear was experimentally fitted to six new locomotives (D49/3) and in the following year the rotary cam version was applied to two further locomotives (D49/2). This latter modification formed the basis for a series, constructed from 1932, known as the Hunt class.
Rutherford (BackTrack, 15, 292) noted that Darlington Drawing Office, under the chief locomotive draughtsman, R. J. Robson, undertook all the design work and does not seem to have been closely supervised by Gresley or Doncaster as to detail features. The derived valve gear was placed behind the cylinders and its joints were kept away from smokebox char. The valves themselves were easy to remove for inspection without dismantling the valve gear.
