Caledonian Railway 72 Class
The Caledonian Railway 72 Class was a class of 4-4-0 steam locomotives introduced by William Pickersgill for the Caledonian Railway in 1920. Thirty-two locomotives were built and all survived to be taken over by the London, Midland and Scottish Railway in 1923 and by British Railways in 1948. The earlier 113 Class, of which 16 were produced, were similar but slightly smaller. These were the Caledonian's last express passenger locomotives, and technically, the last of the Dunalastair series, and were unofficially dubbed, Dunalastair V.
Numbering
The two classes together totalled 48 locomotives. No. 54481 was scrapped after an accident at Gollafield Junction in 1953, the remainder were withdrawn between 1959 and 1962.Dimensions
