LNER Thompson Class A2 may refer to:

LNER Thompson Class A2/1 class of 4 three-cylinder 4-6-2 locomotives

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.

LNER Thompson Class A2/2 class of 6 three-cylinder 4-6-2 locomotives rebuilt from P2 class 2-8-2 locomotives

The London and North Eastern Railway Class A2/2 was a class of six 4-6-2 steam locomotives rebuilt by Edward Thompson in 1943 and 1944 from his predecessor’s P2 Class of 2-8-2 express passenger locomotives. The rebuilds were not particularly successful and all were withdrawn and scrapped between 1959 and 1961.

LNER Thompson Class A2/3 class of 15 three-cylinder 4-6-2 locomotives

The London and North Eastern Railway (LNER) Class A2/3 was a class of 4-6-2 steam locomotives. They were newly constructed locomotives, fulfilling the requirement identified by Edward Thompson for a standard express passenger locomotive of the 4-6-2 arrangement with 6 ft 2 in (1.880 m) driving wheels. Fifteen engines were constructed according to this original design, but following the retirement of Thompson as CME, the remaining fifteen locomotives that were planned were immediately redesigned and ultimately emerged as Peppercorn Class A2.

The Great Northern Railway Class H4 was a class of 2-6-0 steam locomotive designed for mixed-traffic work.

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 an 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's academic background contrasts with that of his predecessor Nigel Gresley, who had also attended Marlborough, but then gained practical experience as a pupil at Horwich Works.

LNER Class B17 class of 73 thee-cylinder 4-6-0 locomotives

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.

LNER Class P1 class of 2 three-cylinder 2-8-2 locomotives

The London and North Eastern Railway Class P1 Mineral 2-8-2 Mikado was a class of two steam locomotives designed by Nigel Gresley. They were two of the most powerful freight locomotives ever designed for a British railway. It was initially intended they be a more powerful 2-10-0 version of the earlier Class O2 2-8-0s. The design was submitted in August 1923, for use between Peterborough and London, and also between Immingham and Wath marshalling yard. The power was quoted as being 25% more than the O2.

LNER Class A2 class of 5 British three-cylinder 4-6-2 locomotives, later LNER class A2

The first London and North Eastern Railway (LNER) Class A2 was a class of 4-6-2 steam locomotive designed by Vincent Raven for the North Eastern Railway. Two were built by the NER in 1922 before the grouping and another three by the LNER in 1924. Their LNER numbers were 2400–2404. All five locomotives were named by the LNER.

LNER Thompson/Peppercorn Class K1 class of 70 British 2-6-0 locomotives

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 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.

LNER Class V4 class of 2 three-cylinder 2-6-2 locomotives

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.

LNER Thompson Class A1/1 class of 1 three-cylinder 4-6-2 locomotive rebuilt from Class A1 (Gresley)

The LNER Class A1/1 consisted of a single 4-6-2 "Pacific" express passenger locomotive rebuilt in 1945 from an A1 class locomotive, by Edward Thompson. It was intended as the prototype of a new design of pacific locomotives improving the A4 design of Thompson’s predecessor Sir Nigel Gresley. No further examples were built due to Thompson’s retirement in 1946.

The M&GN Class C was a class of 4-4-0 steam tender locomotives of the Midland and Great Northern Joint Railway.

NER Class Y class of 20 British 4-6-2T locomotives

The North Eastern Railway (NER) Class Y 4-6-2T tank locomotives were designed whilst Wilson Worsdell was Chief Mechanical Engineer, but none were built until 1910 by which time Vincent Raven had taken over.

The London and North Eastern Railway (LNER) Class O6 was a class of 2-8-0 steam locomotives of the Stanier Class 8F type.

The London and North Eastern Railway (LNER) operated various classes steam locomotives with a 4-6-2 wheel arrangement. The LNER operated more pacifics than any other of the Big Four British railway companies, and they were mostly used for express passenger work along the East Coast Main Line, though later in their lives many were displaced to other lines.

The LNER Class J64 was a class of three 0-6-0T steam locomotives of the London and North Eastern 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.
