The Great Central Railway Class 9N, classified A5 by the LNER, was a class of 4-6-2 tank locomotives designed by John G. Robinson for suburban passenger services.
[1] They ordered a fourth batch of ten from Gorton, but this was not built until after the 1923 Grouping, under which GCR became part of the newly formed London and North Eastern Railway (LNER).
[1] The LNER then ordered a fifth batch of 13 to a modified design, incorporating reduced boiler mountings and detail differences, and these were built by the outside contractors Hawthorn, Leslie & Co. during 1925–26 (works numbers 3616–28).
[4] Forty-three locomotives passed to British Railways in 1948, and between 1948 and 1951 their numbers were increased by 60000.
