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 (as NER class 4.6.2).[1] Two were built by the NER in 1922 before the grouping and another 3 by the LNER in 1924. Their LNER numbers were 2400–2404. All five locomotives were named by the LNER. Because of the great length of their parallel boilers, the Raven pacifics earned the nickname 'Skittle-alleys'.

LNER standardisation[edit]

The Great Northern Railway's Class A1, which was a more technically advanced machine, was chosen as the LNER's standard express passenger locomotive so no more Raven A2s were built.

Stock list[edit]

Name Built Withdrawn
2400 City of Newcastle December 1922 April 1937
2401 City of Kingston upon Hull December 1922 July 1936

No. 2404 was unique amongst the class in being rebuilt in 1929 with a Gresley A1-style taper boiler.[2]


All the Raven A2s were withdrawn in 1936–1937 and none have survived into preservation.
