Between 1990 and 1992, Spoornet placed fiftyClass 10E1, Series 2 electric locomotives with a Co-Co wheel arrangement in mainline service.

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.

[1] The Class 10E2, Series 2 introduced the new Spoornet orange livery with a yellow and blue chevron pattern on the cowcatchers.

In the late 1990s at least one was repainted in the Spoornet blue livery with outline numbers on the long hood sides.
