services on the Reef were being worked by Class B tank locomotives which had been inherited from the Nederlandsche-Zuid-Afrikaansche Spoorweg-Maatschappij (NZASM) via the Imperial Military Railways (IMR). Since the loads were fast becoming too heavy for them, the Class F was designed and ordered as a replacement, intended for the suburban passenger services between Springs and Randfontein. Hyde considered the Class F and the Class 9 as two of his most successful designs for the CSAR. The tank locomotives were very attractive in appearance, with double red lining on their black livery. The IMR tradition of polished copper-capped chimneys, brass domes and boiler bands was continued on the CSAR. The locomotives were always maintained in immaculate condition while in service and became affectionately known as the Chocolate Boxes. The last of the Class F was withdrawn from service by 1931.
