TheGCR Class 5A was a class of seven0-6-0Tsteams designed byJohn G. Robinson for work in docks operated by theGreat Central Railway.^[1] They passed to theLondon and North Eastern Railway at the grouping in 1923 and received the LNER classification J63.

The class was introduced in 1906 as a replacement for theGCR Class 4dock shunters, based on his predecessor'sGCR Class 5 but with side tanks rather than saddle tanks. A seventh locomotive was built in 1914.

All seven examples survived intoBritish Railways ownership in 1948, at least one being at Immingham in 1952,^[2] and at least one atConnah's Quay in 1954.^[3] They were all withdrawn between 1953 and 1957.
