Thompson Class A2/2 'Cock O' The North' BR Early No.60501 4-6-2 Steam Locomotive

60501 Cock o' the North spent eighty-three days in Doncaster Works between 24 June and 14 September 1944 being rebuilt to Class A2/2 and received the Diagram 118 boiler during a general overhaul at Doncaster between 17 September and 24 October 1952. 60501 Cock o' the North was allocated to 50A York (North) at this time, mainly working fast goods and slow passenger turns.

But there were occasional appearances on southbound York passenger diagrams working to Kings Cross, odd appearances on the Great Central line and the occasional diagram between Leeds and York with Neville Hill crews.
