[1] The 3 kV DC Class 10E1, Series 1 electric locomotive was designed for the South African Railways (SAR) by the General Electric Company (GEC) and built by Union Carriage & Wagon (UCW) in Nigel, Transvaal.

GEC supplied the electrical equipment while UCW was responsible for the mechanical components and assembly.

Contrary to prior UCW practice, GEC works numbers were allocated to the Class 10E1 locomotives.

[4] All the Class 10E1, Series 1 locomotives were delivered in the SAR red oxide livery with signal red buffer beams and cowcatchers and a yellow V stripe on the ends, folded over to a horizontal stripe below the side windows.
