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.
Manufacturer
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 had 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.
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 no. 2 end. A passage along the centre of the locomotive connects the cabs, which are identical, except that Cab 2 is where the handbrake is located.
Brakes
While the locomotive itself used air brakes, it was only equipped to operate trains with vacuum brakes. While hauling a train, the locomotive's air brake system would be made subordinate to the train's vacuum brake system and would come into operation as the vacuum brakes were being applied, gradually building up to its maximum of 350 kilopascals (51 pounds per square inch). While working a train downgrade, the locomotive's regenerative braking system would also work in conjunction with the train's vacuum brakes.
The locomotive's air brakes would usually only be used along with the train brakes during emergencies. Under normal circumstances the train would be controlled, using the train brakes alone to slow down and stop.
While the locomotive was stopped, the air brakes on each bogie could be applied independently. The handbrake or parking brake, located in Cab no. 2, only operated on the unit's last axle, or no. 7 and 8 wheels.
Class 5E series
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 160 Class 5E locomotives were delivered, 60 Series 1, 45 Series 2 and 55 Series 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
The Class 5E introduced a locomotive body shape which eventually became the most prolific to ever run on South African rails, serving on all the 3 kV DC lines country-wide. The body shape and dimensions were 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 which was begun in 2000.
Industrial service
Three Class 5E, Series 2 locomotives were sold into industrial service.

Illustration
The main picture shows Series 2 no. E326 and E319 and Series 1 no. E297, departing Touws River and heading northeast towards Beaufort West in 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 which was taken at an accident scene near Olifantsfontein in 1975.
