South African Class 6E1, Series 10
Encyclopedia
Between 1982 and 1984 the South African Railways placed fifty-five Class 6E1, Series 10 electric locomotives with a Bo-Bo wheel arrangement in service.
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.
While some Class 6E1 series are visually indistinguishable from their predecessors or successors, some externally visible changes did occur over the years. Series 2 and all subsequent Class 6E1 series can be distinguished from Series 1 locomotives by their sandboxes that are not mounted on the bogies as before, but along the bottom edge of the locomotive body with the sandbox lids fitting into recesses in the body sides.
Series 8 and later locomotives can be distinguished from all older models by the large hatch door on each side, below the second small window to the right of the side door on the roof access ladder side, and below the first window immediately to the right of the door on the other side.
The Series 9 to Series 11 locomotives were visually indistinguishable from each other, but could be distinguished from all earlier models by the rainwater drainage holes on their lower sides. These holes were usually covered by so-called buckets, but the covers were omitted on a few locomotives. Further distinctions were the end doors that were recessed into the doorframes on Series 9 to Series 11 locomotives, compared to earlier models that had the end doors flush with the doorframes. In addition, unlike all earlier models, all four doors on Series 9 to Series 11 locomotives had rounded corners.
s are at waist level when standing inside the locomotive, making it impossible to open the door from outside without first climbing up high enough to reach the handle while hanging on to the side handrails with one hand only. Crews therefore often chose to leave the doors ajar when parking and exiting the locomotives.
The side doors with two interconnected latch handles on the outside that were introduced on the Class 7E1, with one handle mounted near floor level and the other at mid door level, were also introduced on the Class 6E1 beginning with Series 9.

By June 2005 all Series 10 locomotives except numbers E2111 and E2134 were rebuilt to Class 18E. The fate of the two exceptions is not known and they are presumed to have been scrapped.
Manufacturer
The Class 6E1, Series 10 3 kV DC electric locomotive was designed and built for the South African Railways (SAR) by Union Carriage and Wagon (UCW) in Nigel, Transvaal, with the electrical equipment supplied by the General Electric Company (GEC). Fifty-five locomotives were delivered between 1982 and 1984, numbered E2086 to E2140.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.
Bogies
To ensure the maximum transfer of power to the rails without causing wheel slip, the Class 6E1 was built with sophisticated traction links between the bogies and the frames and equipped with electronic wheel slip detection. These traction struts and linkages were to become a distinguishing feature of most subsequent South African electric locomotive models.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. A passage along the centre of the locomotive connects the cabs.Series identifying features
The Class 6E1 was produced in eleven series over a period of nearly sixteen years, nine hundred and sixty units altogether, all built by UCW. This makes the 6E1 the most numerous single locomotive class ever to have seen service in South Africa and serves as ample proof of a highly successful design.While some Class 6E1 series are visually indistinguishable from their predecessors or successors, some externally visible changes did occur over the years. Series 2 and all subsequent Class 6E1 series can be distinguished from Series 1 locomotives by their sandboxes that are not mounted on the bogies as before, but along the bottom edge of the locomotive body with the sandbox lids fitting into recesses in the body sides.
Series 8 and later locomotives can be distinguished from all older models by the large hatch door on each side, below the second small window to the right of the side door on the roof access ladder side, and below the first window immediately to the right of the door on the other side.

Crew access
The Class 5E, 5E1, 6E and early 6E1 locomotives are notoriously difficult to enter since their lever-style door handleDoor handle
A door handle is an attached mechanism used to open or close a door. In the United States, door handle can refer to any fixed or lever-operated door latch device, including on car doors. The term door knob tends to refer to round operating mechanisms.-History:The first documented invention of the...
s are at waist level when standing inside the locomotive, making it impossible to open the door from outside without first climbing up high enough to reach the handle while hanging on to the side handrails with one hand only. Crews therefore often chose to leave the doors ajar when parking and exiting the locomotives.
The side doors with two interconnected latch handles on the outside that were introduced on the Class 7E1, with one handle mounted near floor level and the other at mid door level, were also introduced on the Class 6E1 beginning with Series 9.
Service
The Class 6E1 family saw service all over both of the Transnet Freight Rail (TFR) 3 kV DC main line and branch line networks.Cape Western network
The smaller network is the Cape Western line between Cape Town and Beaufort West, with the locomotives based at the Bellville Depot in Cape Town. None of the Series 9 to Series 11 locomotives saw service here.Northern network
The larger network covers portions of the Northern Cape, the Free State, Natal, Gauteng, North West Province and Mpumalanga, the main routes in this vast area being as follows:- From Johannesburg in Gauteng via Kimberley to Hotazel in the Northern Cape.
- From Johannesburg to Bloemfontein in the Free State.
- From Johannesburg to Durban in Natal.
- From Johannesburg via Pretoria in Gauteng and Witbank in Mpumalanga to Komatipoort on the Mozambique border, as well as to Derwent and Roossenekal.
- From Johannesburg via Springs to Witbank.
- From Johannesburg via Coligny to Lichtenburg.
- From Durban in Natal to Empangeni in the north and Port Shepstone in the south.
- From Ermelo to Ogies and Wonderfontein in Mpumalanga.
- From Kroonstad in the Free State via Bethlehem and Ladysmith to Vryheid in Natal.
The electric locomotives allocated to depots within this network were largely pooled and could operate anywhere in the network as required by the Operating Department, but they returned to their home depots for maintenance every twenty-eight days.
Rebuilding to Class 18E

Beginning in 2000 Spoornet embarked on a program to rebuild Class 6E1, Series 6 to Series 11 locomotives to Class 18E, Series 1 locomotives.
