In 1978 and 1979 the South African Railways placed one hundred Class 7y electric locomotives with a Co-Co wheel arrangement in mainline service, numbered in the range from E7001 to E7100. They were the first 25 kV AC locomotives to be introduced in South Africa, built by Union Carriage and Wagon in Nigel, Transvaal and designed by the 50 c/s Group (ACEC, AEG-Telefunken, Siemens, Alsthom-Atlantique, Société MTE and Brown Boveri). Beginning with the Class 7E, the class number was included in the running number on electric locomotives.
