South African Class 10E2
Encyclopedia
In 1989 and 1990 the South African Railways placed twenty-five Class 10E2 electric locomotives with a Co-Co wheel arrangement in main line service.
and built by Union Carriage and Wagon (UCW) in Nigel, Transvaal. Toshiba of Japan supplied the electrical equipment while UCW was responsible for the mechanical components and assembly. UCW delivered twenty-five locomotives to the SAR in 1989 and 1990, numbered 10-101 to 10-125.
UCW did not allocate builder’s numbers to the locomotives it built for the SAR. While the usual practice by most other locomotive builders was to allocate builder’s numbers or works numbers to record the locomotives built by them, UCW simply used the SAR running numbers for their record keeping.
or rheostatic braking, as the situation demands. Both traction and electric braking power are continuously variable, with the electric braking optimised to such an extent that maximum use will be made of the regenerative braking capacity of the 3 kV network, with the ability to automatically change over to rheostatic braking whenever the overhead supply system becomes non-receptive.
In 1998 a number of Spoornet’s electric locomotives and most of their Class 38-000 electro-diesel locomotives were sold to Maquarie-GETX (General Electric Financing) and leased back to Spoornet for a ten year period that was to expire in 2008. Of the Class 10E2, numbers to 10-125 were later also included in this leasing deal.

Characteristics
The Class 10E2 was introduced as a standard 3 kV DC heavy goods locomotive. With a continuous power rating of 3090 kW, four Class 10E2 locomotives are capable of performing the same work as six Class 6E1.Brakes

Orientation
These dual cab locomotives have a roof access ladder on one side only, just to the right of the cab access door. The roof access ladder end is marked as the number 2 end.Identifying Features
In visual appearance the Class 10E2 can be distinguished from the Class 10E by the roof ends and the sills. The Class 10E has riffled roof ends and parts of the sill protrude slightly past the bottom edge of the body sides. The Class 10E2 has smooth unriffled roof ends and no part of the sill protrudes past the bottom edge of the body sides.Service
The Class 10E2 is employed chiefly to haul ore trains on the line between Kimberley and Hotazel in the Northern Cape and it also works between Kimberley and the Witwatersrand. Most are shedded at Kaserne near Johannesburg, with several also at Beaconsfield near Kimberley.In 1998 a number of Spoornet’s electric locomotives and most of their Class 38-000 electro-diesel locomotives were sold to Maquarie-GETX (General Electric Financing) and leased back to Spoornet for a ten year period that was to expire in 2008.

Liveries
The main picture shows 10-103 in SAR Gulf Red and whiskers livery. On locomotives that were repainted in Transnet Freight Rail livery circa 2011, the running numbers are displayed as, for example, "E10110" instead of the earlier "10-110".See also
