The vehicles of the class GC of the South African Railways (SAR) were articulated locomotives of the Garratt design . With axle loads of around 10.6 t, they were intended for light superstructures; the axis order was (1'C1 ') (1'C1').
The locomotive largely corresponded to two Garratts that the New Cape Central Railway (NCCR) had procured in 1923 and that were classified as class GK after the SAR took over this railway . Class GC, however, had a smaller cylinder diameter and therefore a lower tensile force.
In parallel to the GC class, the North British Locomotive Works acquired a single Modified Fairlie locomotive on a trial basis . This machine, referred to as class FC , agreed with class GC in all essential dimensions, so that it was possible for the railway to compare both types of joint with one another.
The GC class locomotives remained in service until 1964 and were last stationed in Pietermaritzburg .
