The GCR Class 5A 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.[1] They passed to the London and North Eastern Railway at the grouping in 1923 and received the LNER classification J63.

History[edit]

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in 1948, at least one being at Immingham in 1952,[2] and at least one at Connah's Quay in 1954.[3] They were all withdrawn between 1953 and 1957.
