Between 1937 and 1949 the South African Railways placed two hundred and thirty-five Class 19D locomotives with a 4-8-2 Mountain wheel arrangement in service, built in four batches by five manufacturers (Friedrich Krupp AG, Borsig Lokomotiv Werke, Škoda Works, Robert Stephenson and Hawthorns, and North British Locomotive Company). Between 1951 and 1953 thirty-three more were built by Henschel and Son for other operators like Rhodesia Railways, Benguela Railway in Angola and the Nkana and Wankie mines. The South African Class 19D, nicknamed Dolly, was numbered in the ranges 2506 to 2545, 2626 to 2770 and 3321-3370. The first batch of pre-war Krupp built locomotives were delivered with domeless boilers. The post-war batch of North British built locomotives were delivered with Vanderbilt type torpedo tenders with cylindrical water tanks that ran on three axle Buckeye bogies. Since the Watson Standard no. 1A boilers and the tenders were interchangeable, the domeless boilers and torpedo tenders migrated over time between the different batches of Dollies and even to other members of the Class 19 family.
