The GCR Class 5A(LNER Class J63) was a class of seven 0-6-0 steam tank locomotives designed by John G. Robinson for work in docks operated by the Great Central Railway. They passed to the London 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 the GCR Class 4 dock shunters, based on his predecessor’s GCR Class 5 but with side tanks rather than saddle tanks. A seventh locomotive was built in 1914.

All seven examples survived into British Railways ownership in 1948. They were all withdrawn between 1953 and 1957.
