The South African Railways Class C1 4-6-2T of 1901 was a steam locomotive from the pre-Union era in the Natal Colony. Between 1879 and 1885, the Natal Government Railways placed 37 4-6-0 Tenwheeler type tank steam locomotives in service. In 1901, one of them was rebuilt to a 4-6-2T Pacific type locomotive and in 1912, when it was assimilated into the South African Railways, it was renumbered and designated Class C1. During 1912, four more of these 4-6-2T locomotives were built by the South African Railways in the Durban workshops, using mostly surplus material.
