South African Class 10E2

The South African Class 10E2 of 1989 is a South African electric locomotive from the South African Railways era.

In 1989 and 1990 the South African Railways placed twenty-five Class 10E2 electric locomotives with a Co-Co wheel arrangement in mainline service.^[2]

Manufacturer

The 3 kV DC Class 10E2 electric locomotive was designed for the South African Railways (SAR) by Toshiba 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.^[4]

UCW delivered twenty-five locomotives to the SAR in 1989 and 1990, numbered in the range from 10-101 to 10-125. UCW did not allocate builder’s numbers to the locomotives it built for the SAR, but used the SAR unit numbers for their record keeping.^[2]

Characteristics

The Class 10E2 was introduced as a standard 3 kV DC heavy goods locomotive. With a continuous power rating of 3,090 kilowatts (4,140 horsepower), four Class 10E2 locomotives are capable of performing the same work as six Class 6E1.^[1]

Brakes

The locomotive makes use of either regenerative 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 DC network, with the ability to automatically change over to rheostatic braking whenever the overhead supply system becomes non-receptive.^[1]

The entire fleet of the Class 10E family of electric locomotives features electronic chopper control, which is smoother in comparison to the rheostatic resistance control that was used in the Classes 1E to 6E1 electric locomotives.^[5]

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.^[3]

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.^[3]

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.^[2]

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 10-106 to 10-125 were later also included in this leasing deal.^[2]

Liveries illustrated

The main picture shows no. 10-103 in SAR Gulf Red and whiskers livery while the following pictures illustrate other liveries that were applied to the Class 10E2, as well as the difference between the two sides of the locomotive. On locomotives that were repainted in Transnet Freight Rail livery from circa 2011, the locomotive numbers are displayed as, for example, either "E10110" or "E10 125" instead of the earlier "10-110".
