The Caledonian Railway 72 Class was a class of 4-4-0 steam locomotives introduced by William Pickersgill for the Caledonian Railway (CR) in 1920. Thirty-two locomotives were built and all survived to be taken over by the London, Midland and Scottish Railway (LMS) in 1923 and by British Railways (BR) in 1948. The earlier 113 Class (introduced in 1916), of which 16 were produced, were similar but slightly smaller.
