For use as shunters and for light short-distance freight trains, South African Railways ordered a total of 101 SW1002 from EMD. Between 1980 and 1984, they received two orders of 50 and 51 locomotives which were designated class 36-200. Like the SW1000 and SW1001 designed for service in the US, they got the 8-645E engine that delivered 1,140 hp for a short time. By 1991, a total of six more had been delivered to three customers in the industry, bringing the total number to 107. Nearly all had been produced a General Motors South Africa (GMSA), only one of the three locomotives built for Iscor had been built by GM-Astarsa in Argentina.
