The South African Railways Class 21 2-10-4 of 1937 was a single experimental steam locomotive, number 2551, built by the North British Locomotive Company in Glasgow and delivered in 1937. A.G. Watson designed it as a mixed traffic engine for light rail, and it was the first Texas type, ten-coupled arrangement tried on the system, with flangeless third and fourth coupled wheelsets for tight curves and duralumin footplates to save weight. Its tractive effort of 43,700 pounds-force was higher than the Class GF Garratt it rivalled. The design was never repeated, a heavier Class 22 was never built, and the engine was scrapped in 1952 after fifteen years in service.
