South African Class 6E1, Series 6
Encyclopedia
Between 1975 and 1977 the South African Railways placed one hundred Class 6E1, Series 6 electric locomotives with a Bo-Bo wheel arrangement in main line 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. The Series 6 and Series 7 locomotives are visually indistinguishable from each other, but can be distinguished from the older series models by the rainwater beading above the small grilles on the sides just to the right of the side doors.
The electric locomotives allocated to depots within this network are largely pooled and can operate anywhere in the network as required by the Operating Department, but they return to their home depots for maintenance every twenty-eight days.
In 2011 the Class 6E1 began to be withdrawn from the Natal corridor (NatCor) line between Johannesburg and Durban, being replaced with Class 18E
locomotives.
The coastal sections from Durban to Empangeni in the north and Port Shepstone in the south were dieselised at the end of October 2011, using EMD Class 34
and Class 37-000

and allocated a single running number to each pair, with the individual locomotives in the pairs inscribed "A" or "B". The aim was to accomplish savings on cab maintenance by coupling the locomotives at their number 1 ends, abandoning the number one end cabs in terms of maintenance and using only the number two end cabs. Most were later either disbanded with the locomotives reverting to Class 6E1 and regaining their original numbers, or getting rebuilt to Class 18E.
At least nine Series 6 locomotives were part of such Class 16E pairs.
locomotives at the Koedoespoort Transwerk workshops. In the process the cab at the number 1 end was stripped of all controls in order to have a toilet installed to accommodate female crew, thereby forfeiting the loco's bi-directional ability.
Manufacturer
The Class 6E1, Series 6 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). One hundred locomotives were delivered between 1975 and 1977, numbered E1646 to E1745.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 South African 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. The Series 6 and Series 7 locomotives are visually indistinguishable from each other, but can be distinguished from the older series models by the rainwater beading above the small grilles on the sides just to the right of the side doors.
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.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 are largely pooled and can operate anywhere in the network as required by the Operating Department, but they return to their home depots for maintenance every twenty-eight days.
