In 1910 the Natal Government Railways placed two Class A steam locomotives with a 4-6-2 Pacific wheel arrangement in service, built in their Durban workshops. In 1912, when these locomotives were assimilated into the South African Railways, they were renumbered and classified as Class 2C. The 2A and 2B classifications were never used.
When more locomotives were required for passenger traffic on the section between Estcourt and Charlestown via Ladysmith on the Natal Government Railways (NGR) mainline, where gradients were less severe than in the coastal region, two locomotives were built in the Durban workshops of the NGR. They were designed by NGR Locomotive Superintendent D.A. Hendrie and were a redesigned version of his NGR Class A of 1905. The Hendrie C, as it was also known, was similar to the Class A Hendrie A in general proportions, but with Walschaerts valve gear, slightly larger diameter driving wheels, a larger boiler and a more enclosed cab that offered better protection to the crew. When they were placed in service in 1910, they were also designated NGR Class A with numbers 11 and 12.
The Union of South Africa was established on 31 May 1910, in terms of the South Africa Act, enacted by the Parliament of the United Kingdom. One of the clauses in the Act required that the three Colonial Government railways, the Cape Government Railways, the NGR and the Central South African Railways, also be united under one single administration to control and administer the railways, ports and harbours of the Union. While the South African Railways (SAR) came into existence in 1910, the actual classification and renumbering of all the rolling stock of the three constituent railways required careful planning and was only implemented with effect from 1 January 1912.
After serving on the Estcourt to Charlestown section for many years, they were transferred to the Witwatersrand for a short period, after which they were transferred to the section between Komatipoort and Waterval Boven in the Eastern Transvaal. Here they worked passenger and fast perishables trains until they were withdrawn in 1936.
