The GCR Class 5 (LNER Class J62) was a class of twelve steam tank locomotives designed by Harry Pollitt (engineer) for work in docks operated by the Manchester, Sheffield and Lincolnshire Railway (MS&LR) later renamed Great Central Railway (GCR).
These locomotives were designed by Pollitt for working at Grimsby and other dock locations. (No. 891 was the last engine to be built by the MS&LR, and No. 892 the first engine to be built by the GCR both in 1897.) They passed to the London and North Eastern Railway at the grouping in 1923 and received the LNER classification J62. Withdrawals began in 1935, but there were three examples surviving in 1948 which passed to British Railways ownership. The last example was withdrawn in 1951.
One example (No. 889) was rebuilt in 1903 as an but reverted to its original form in 1918 after a collision.
