DIESEL-ELECTRIC LOCOMOTIVES USED IN SOUTH AFRICA

A diesel-Electric locomotive uses a diesel motor driving generators producing direct current (DC) which in turn power either 4 or 6 electric traction motors at the wheels, simlar to those traction motors on the electric locomotives. Often the diesel engines used are turbo charged and varies from 8 to 16 sylinder.

Needing a branchline diesel locomotive, the class 35 was ordered in 1972 by the SAR. There are four number series, denoting the country of manufacture. Series 35-000 denotes manufacture by GE in the USA, 1972-1976, manufacturers type U15C 35-400 manufactured in South Africa., 1972-1976 35-200 and 35-600 General Motors (EMD) built the first 25, the rest being locally built, all between 1974 and 1976. The manufacturers type is GT18MC The GE models have a four stroke V8 diesel which is turbo charged and aftercooled. The GM (EMD) models have a two stroke V8 turbocharged diesel which is also aftercooled. Both models use a DC generator. Both models have dynamic brakes.
