These were the Caledonian's last express passenger locomotives, and technically, the last of the Dunalastair series, and were unofficially dubbed, Dunalastair V.[citation needed] The two classes together totalled 48 locomotives.

54481 was scrapped after an accident at Gollafield Junction in 1953, the remainder were withdrawn between 1959 and 1962.
