The London and North Eastern Railway (LNER) Thompson Class B1 is a class of steam locomotive designed by Edward Thompson for medium mixed traffic work. [1]
It was the LNER's equivalent to the highly successful GWR Hall Class and the LMS Stanier Black Five, two-cylinder mixed traffic 4-6-0s. However, it had the additional requirement of having to be cheap because, due to wartime and post-war economies, the LNER, never the richest railway company, had to make savings. [2]
Introduced in 1942, the first example, No. 8301, was named Springbok in honour of a visit by Jan Smuts. The first 40 of the class were named after breeds of antelopes and the like, and they became known as bongos after 8306 Bongo . 274 were built by the LNER. 136 were built by British Railways after nationalisation in 1948. The total number in stock at any one time however was only 409 as 61057 was involved in an accident in 1950 and was scrapped. [3]
The prototype for the new B class (later classified B1) 4-6-0 was built at Darlington and entered service on 12 December 1942. It was the first 2-cylinder main-line locomotive constructed for the LNER since the grouping, such had been Sir Nigel Gresley's faith in the 3 cylinder layout. With cost saving a wartime priority the LNER's draughtsmen went to great lengths to re-use existing patterns, jigs and tools to economise on materials and labour. Extensive use was made of welding instead of steel castings. The boiler was derived from the Diagram 100A type fitted to the LNER Class B17 Sandringham 4-6-0s but with a larger grate area and an increase in boiler pressure to 225 pounds per square inch (1.55 MPa). [4]
The appearance of No. 8301 (subsequently renumbered No. 1000) coincided with a visit to Britain by the Prime Minister of South Africa, Field Marshal Jan Smuts, and, as mentioned above, it was named Springbok. 18 other B1s took the names of LNER directors. Not that there were many B1s to be named during the war years: constraints on production meant that the first ten were not completed until 1944. However, Thompson then placed substantial orders with two outside builders: Vulcan Foundry and the North British Locomotive Company of Glasgow. Between April 1946 and April 1952 NBL built 290 B1s. Over the period the cost of each engine rose from £14,893 to £16,190. Vulcan Foundry contributed 50 at £15,300 apiece. Orders for the B1s, which became Nos. 61000–61409 under British Railways, totalled 410. [5]
The B1s operated throughout LNER territory. The first batch was distributed among depots on the former Great Eastern Railway section: Ipswich, Norwich, and Stratford in London. They were an immediate success and were soon working the Liverpool Street - Harwich boat trains, the Hook Continental , the Day Continental and the Scandinavian. B1s were also a familiar sight on other top-link workings such as The East Anglian , The Broadsman and The Fenman . During the 1950s over 70 B1s were stationed on ex-GE lines. [6]
They enjoyed similar popularity on ex-Great Northern and Great Central territory. Engines based at Darnall, Sheffield were regularly rostered for the Master Cutler and South Yorkshireman expresses. Elsewhere there were substantial allocations in Scotland, West Yorkshire and East Yorkshire.
If any fault is to be highlighted on the B1, it must be the ride quality. O. S. Nock often criticised the B1s for a poor ride, not something many were used to on the Gresley engines. The B1 was very cheap to build, but the final result was an engine that was somewhat lacking in the quality LNER men had come to expect. The two-cylinder layout gave the engines good starting power and excellent hill climbing abilities, but it also caused very bad hunting effects, a result of the use of cut-offs of up to 75% (a 10% advance on Gresley engines), and as such they were less kind on the passengers they carried than the B17s they replaced. [7]
Overall, however, it was entirely necessary that the B1s be introduced, because the LNER was operating a large number of engines that were well past their economic life. It was somewhat ironic that among the engines that came under threat with the arrival of the B1s were the ones that Thompson admired the most: the engines of the North Eastern Railway designed by Vincent Raven (his father-in-law).
B1s could be found over almost all of the LNER network, and that of the BR Eastern and North Eastern Regions.
The last scheduled steam-hauled passenger train to arrive in Liverpool Street was the up Day Continental on 9 September 1962 hauled by a B1 61156. [8]
59 of the 410 locomotives were named. Early B1s were named after species of antelope, whilst later engines were named after members of the board of directors of the LNER. This led to the fact that the Class B1 contained the shortest name given to a British locomotive ((6)1018 Gnu) and one of the longest ((6)1221 Sir Alexander Erskine-Hill).

With the change in the policies of British Railways, the B1s were withdrawn long before their projected economic working life. Excepting No. 61057 which was destroyed in an accident in 1950, the first normal withdrawal was No. 61085 in November 1961. The remaining locomotives were withdrawn between 1962 and 1967.

After withdrawal from capital stock, 17 were taken into departmental stock where they were used as boilers for carriage heating. For this they had their couplers removed so they could not haul trains, though they could still propel themselves.

The LNER Class A4 is a class of streamlined 4-6-2 steam locomotive designed by Nigel Gresley for the London and North Eastern Railway in 1935. Their streamlined design gave them high-speed capability as well as making them instantly recognisable, and one of the class, 4468 Mallard, holds the record as the world's fastest steam locomotive. Thirty-five of the class were built to haul express passenger trains on the East Coast Main Line route from London Kings Cross via York to Newcastle, and later via Newcastle to Edinburgh, Scotland. They remained in service on the East Coast Main Line until the early 1960s when they were replaced by Deltic diesel locomotives; they themselves proving to be worthy successors to the A4s. Several A4s saw out their remaining days until 1966 in Scotland, particularly on the Aberdeen – Glasgow express trains, for which they were used to improve the timing from 3.5 to 3 hours.
The London and North Eastern Railway (LNER) Class V2 2-6-2 steam locomotives were designed by Sir Nigel Gresley for express mixed traffic work, and built at the LNER shops at Doncaster and Darlington between 1936 and 1944. The best known is the first of the class, 4771 Green Arrow, which is the sole survivor of the class.
London and North Eastern Railway's (LNER) Peppercorn Class A1 is a class of 4-6-2 "Pacific" steam locomotives largely built between 1948 and 1949 at Doncaster and Darlington Works to a design of Arthur Peppercorn. Forty-nine were built for hauling express passenger services on the East Coast Main Line owned by LNER's successor, British Railways' North Eastern Region. None of the original 49 Peppercorn A1s survived into preservation, with the last being scrapped in 1966. The 50th Peppercorn A1, 60163 Tornado, was completed in 2008 as an evolved member of its class.
The London and North Eastern Railway Gresley Classes A1 and A3 locomotives represented two distinct stages in the history of the British 4-6-2 "Pacific" steam locomotives designed by Nigel Gresley. They were designed for main line passenger services and later express passenger services, initially on the Great Northern Railway (GNR), a constituent company of the London and North Eastern Railway after the amalgamation of 1923, for which they became a standard design. The change in class designation to A3 reflected the fitting to the same chassis of a higher pressure boiler with a greater superheating surface and a small reduction in cylinder diameter, leading to an increase in locomotive weight. Eventually all of the A1 locomotives were rebuilt, most to A3 specifications, but no. 4470 was completely rebuilt as Class A1/1.
The London and North Eastern Railway (LNER) Peppercorn Class A2 is a class of steam locomotive designed for express passenger work by Arthur Peppercorn, the chief designer of the LNER after Edward Thompson. All save the first of the 15 built were constructed under British Railways after nationalisation in 1948. Only one example is preserved.
The Great Eastern Railway (GER) Class S69, also known as 1500 Class, and later classified B12 by the London and North Eastern Railway (LNER) is a class of 4-6-0 steam locomotive designed to haul express passenger trains from London Liverpool Street station along the Great Eastern Main Line. Originally they were designed by S. D. Holden, but were much rebuilt, resulting in several subclasses.
Edward Thompson was an English railway engineer, and was Chief Mechanical Engineer of the London and North Eastern Railway between 1941 and 1946. Edward Thompson was born at Marlborough, Wiltshire on 25 June 1881. He was the son of Francis Thompson, assistant master at Marlborough College. He was educated at Marlborough before taking the Mechanical Science Tripos at Pembroke College, Cambridge, earning a third class degree. Thompson entered the railway scene after education, contrasting that of his predecessor Nigel Gresley, who had also attended Marlborough after gaining practical experience as a pupil at Horwich Works.
The London and North Eastern Railway (LNER) Class B17, also known as "Sandringham" or "Footballer" class was a class of 4-6-0 steam locomotive designed by Nigel Gresley for hauling passenger services on the Great Eastern Main Line. In total 73 were built.
The Great Northern Railway (GNR) Class N2 is an 0-6-2T side tank steam locomotive designed by Nigel Gresley and introduced in 1920. Further batches were built by the London and North Eastern Railway from 1925. They had superheaters and piston valves driven by Stephenson valve gear.
The Great Northern Railway (GNR) Class O2 was a class of three-cylinder 2-8-0 steam locomotives designed by Nigel Gresley for freight work and built by the GNR from 1921. Further examples were built by the London and North Eastern Railway (LNER) from 1924.
The London and North Eastern Railway (LNER) Thompson Class B2 was a class of 4-6-0 steam locomotive. It was introduced in 1945 as a two-cylinder rebuild of the three-cylinder LNER Class B17. Ten were rebuilt from Class B17 but no more were rebuilt because of the success of the LNER Thompson Class B1.
The London and North Eastern Railway (LNER) Thompson Class L1 was a class of 2-6-4T steam locomotives designed by Edward Thompson. The prototype no. 9000 was built in 1945, but the remaining 99 were built under British Railways jurisdiction between 1948–1950. The prototype was well received, however the production batch were not, and all were withdrawn and scrapped between 1960 and 1962.
The London and North Eastern Railway (LNER) Class K1 is a type of 2-6-0 (mogul) steam locomotive designed by Edward Thompson. Thompson preferred a simple two-cylinder design instead of his predecessor Nigel Gresley's three-cylinder one. The seventy K1s were intended to be split between the North Eastern Region of British Railways and the Eastern Region of British Railways.
The London and North Eastern Railway Class V4 was a class of 2-6-2 steam locomotive designed by Sir Nigel Gresley for mixed-traffic use. It was Gresley's last design for the LNER before he died in 1941. The V4s had similarities in their appearance and mechanical layout to the V2 "Green Arrow" class. The V2s, introduced some years before, were large and heavy locomotives, with very limited route availability. The V4 was a lightweight alternative, suitable for use over the whole of the LNER network.
The London and North Eastern Railway (LNER) Class V1 and Class V3 were two classes of related 2-6-2T steam locomotive designed by Sir Nigel Gresley. A total of 82 V1s were built with 71 being rebuilt into the higher pressure V3s with an additional ten being built as V3s from the final batch of V1s. The V3 was a development of the V1 with increased boiler pressure and a resultant increase in tractive effort.
London and North Eastern Railway (LNER) Thompson Class B1 No. 1264, is a preserved British steam locomotive.
LNER Thompson Class B1 No. 61306 Mayflower is a 4-6-0 steam locomotive built in 1948 at the North British Locomotive Company to a design by Edward Thompson. It was employed for hauling mixed traffic trains on British Railways' Eastern, North Eastern, and Scottish Regions until it was bought for preservation in 1967, during which it was renumbered and given its current name.
The London and North Eastern Railway (LNER) Thompson Class A2/1 was a class of 4-6-2 steam locomotives built at Darlington locomotive works during 1944. They were originally ordered as Class V2 locomotives, as designed by Sir Nigel Gresley, but were revised during construction into a 4-6-2 'Pacific' arrangement under the instruction of Edward Thompson.
GCR Class 8G was a class of 10 two-cylinder steam locomotives of the 4-6-0 wheel arrangement built in 1906 for the Great Central Railway.
GCR Class 9P was a design of four-cylinder steam locomotive of the 4-6-0 wheel arrangement built for hauling express passenger trains on the Great Central Railway in England. A total of six were built: one in 1917, and five in 1920. They were sometimes known as the Lord Faringdon class, from the name of the first one built.
