Data from "Locomotives Built by Messrs William Beardmore & Co, Ltd", Locomotive Magazine, Volume XXVI [28] (15 July 1920), pp. 161-162. Works numbers were 130-134 in 1920.
As suggested by its class ID, these engines were built along the lines of the standard design of broad-gauge superheated goods locomotives (Locobase 4253). For the steel, ordnance, and shipbuilding colossus, steam locomotives seemed a logical extension. Beginning in 1920, the company managed to produce about 400 locomotives over the next 10 years. These Belpaire-firebox engines featured in one of the largest contracts the company would secure.
