South African Class GMA 4-8-2+2-8-4 still ongoing in 1979, the locomotives were equipped with armour plating around the cab. Since this obscured the number plates, the engine numbers were then usually stencilled on the cabsides. The Class GMAM was similar in size with a similar coal capacity to the Rhodesia Railways 20th class 4-8-2+2-8-4 Garratt, but it had a voracious appetite for coal and frequently ran low on fuel with the result that trains often had to be dumped.
