The South African Class 5E, Series 2 of 1957 is a South African electric locomotive from the South African Railways era.

In 1957 and 1958 the South African Railways placed forty-five Class 5E, Series 2 electric locomotives with a Bo-Bo wheel arrangement in mainline service.[2]

Manufacturer[edit]

The 3 kV DC Class 5E, Series 2 electric locomotive was built for the South African Railways (SAR) by Vulcan Foundry (VF) on a sub-contract from English Electric (EE) who designed the locomotive and supplied the electrical equipment. Forty-five series 2 locomotives were delivered and placed in service in 1957 and 1958, numbered in the range from E319 to E363.[1][3]

Orientation[edit]

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.[2]

They were delivered in a bottle green livery with yellow whiskers. Beginning in 1960, a Gulf Red and yellow whiskers livery gradually replaced the green and yellow.[3]

Class 5E series[edit]

The Class 5E was produced in three series, the EE and VF built Series 1 and the VF built Series 2 and Series 3. The VF built locomotives all have a works number for EE as well as VF, since the order was placed with EE who then subcontracted their construction to VF. Between 1955 and 1959 altogether one hundred and sixty Class 5E locomotives were delivered, sixty Series 1, forty-five Series 2 and fifty-five Series 3.[1][2][3]

According to crews the Class 5E gave a rough ride, which soon earned it the nickname balstamper. The successor Class 5E1 with its new design bogies gave a smoother ride.

Legacy[edit]

The Class 5E was the prototype of what eventually became the most prolific locomotive type to ever run on South African rails, serving on all the 3 kV DC lines country wide. The type was continued with the Class 5E1 in 1959, the Class 6E and the Class 6E1 from 1969 to 1985, and still later with the rebuilding of Class 6E1 locomotives to Class 18E, a project that started in 2000.[2][3][4]

Industrial service[edit]

Three Class 5E, Series 2 locomotives were sold into industrial service.

  • Number E320 was sold to the Impala platinum mine in Rustenburg.
  • Numbers E343 and E356 were sold to the Driefontein gold mine near Carletonville.[1]

Works numbers[edit]

The EE and VF works numbers of the Class 5E, Series 2 and their disposal are shown in the table.[1]

Liveries illustrated[edit]

The main picture shows Series 2 numbers E326 and E319 and Series 1 number E297 departing Touws River, heading northeast towards Beaufort West, circa September 1984. The following pictures depict the SAR Gulf Red and the Driefontein mine liveries. An overhead view of the locomotive is shown in a picture taken at an accident scene near Olifantsfontein in 1975.
