In the early 1960's, the South African Railways dieselised the railway system in South West Africa (now Namibia), with 115 class 32's (U18C1) imported from GE in the USA. Special bogies were fitted, which had a pony truck at the outer ends, to keep the axle loading within limits. In 1966 another ten were placed in service, but these had low short hoods and were model U20C1, designated class 32-200 by SAR. Forty four years later, ex- SAR no. 32-203 survives in service with Sheltam, working on the Free State goldfields and maintained in pristine condition. A classic locomotive!
