Caledonian Railway 944 Class

The Caledonian Railway 944 Class were twelve 4-6-2T passenger tank locomotives designed by William Pickersgill and built in 1917 at the North British Locomotive Company's Hyde Park Works in Glasgow. They were the Caledonian Railway's only Pacific-type engines and its only large passenger tanks, sharing much of their design with the contemporary 60 Class 4-6-0s. They were first used on the Inverclyde Line, where enginemen called them the Wemyss Bay Pugs. Passing to the London, Midland and Scottish Railway in 1923, they were repainted from Caledonian blue into LMS crimson lake and then lined black, and were later displaced from the Inverclyde line by LMS Fowler and Fairburn 2-6-4Ts. By 1948 the survivors were allocated to Beattock shed, mainly for banking duties on Beattock Summit, and all were withdrawn and scrapped between 1946 and 1953.
