South African Class 36-000

The South African Class 36-000 of 1975 is a South African diesel-electric locomotive from the South African Railways era.

Between June 1975 and 1981 the South African Railways placed one hundred and twenty-four Class 36-000 General Electric type SG10B diesel-electric locomotives in service.^[1][2]

Manufacturer

The Class 36-000 type GE SG10B diesel-electric locomotive was designed by General Electric (GE) and built for the South African Railways (SAR) in three batches by the South African General Electric-Dorman Long Locomotive Group (SA GE-DL, later Dorbyl). The first one hundred locomotives were delivered between June 1975 and September 1978, numbered in the range from 36-001 to 36-100, followed in 1981 by two batches of twenty and four locomotives respectively, numbered in the ranges from 36-101 to 36-120 and 36-121 to 36-124 respectively.^[1][2][3]

Class 36 series

The Class 36 locomotive group consists of two series, the GE type SG10B Class 36-000 and the General Motors Electro-Motive Division (GM-EMD) type SW1002 Class 36-200. Both these manufacturers also produced locomotives for the South African Classes 33, 34 and 35.^[2]

Service

Works plate on no. 36-025

The Class 36-000 is a general purpose locomotive that is equipped with two station controls for bi-directional operation. It is used mainly for yard shunting and pickup work to service industrial customers. When placed in service, they were initially distributed for service between Natal and the Western Transvaal, but they were later relocated to the Western and Eastern Cape, the Free State and Gauteng.^[1][3]

A few Class 36-000 locomotives have been observed at Vereeniging and at Port Elizabeth with home depot-applied modifications to their cab roofs in the form of sheetmetal roof extensions to the front and rear to serve as sun-shades.

Class 91-000

Class 91-000 no. 91-010 on Class 36-000 bogies, Swartkops, 21 April 2013

Bogies and traction motors from Class 36-000 locomotives were often used under the 2 ft (610 mm) narrow gauge Class 91-000 GE UM6B diesel-electric locomotives when they were being transferred between the Cape and Natal narrow gauge systems. These "Bigfoot bogies" enabled them to travel under their own power on 3 ft 6 in (1,067 mm) Cape gauge. Bigfoot bogies were also used under the narrow gauge locomotives whenever they had to be exchanged for maintenance purposes, sometimes running under their own power, sometimes hauled dead.^[1]

After most of the Class 91-000 narrow gauge locomotives were retired, one of them was allocated to the Swartkops electric locomotive depot in Port Elizabeth for use as shunting engine. It is also running on Class 36-000 bogies, but with only one bogie powered.
