The Kruger Class was a series of exceptionally imposing-looking (some might say ungainly) steam locomotives designed by William Dean and built at the Swindon Works of the Great Western Railway.


They had outside frames to the six coupled driving wheels, but inside frames for the leading wheels. A distinctive visual feature, initially, was a large saddle-shaped sandbox over the first ring of the boiler. The class had two prototypes: No. 2601, was a 4-6-0, while No. 2602 was a 2-6-0. These were built in 1899, and Nos. 2603-2610, all 2-6-0s, followed later, up to 1903. Though Dean was officially still in charge, Churchward's influence is evident in the rugged design. Their perhaps ironic nickname was after Paul Kruger, the Boer War leader defeated by Lord Roberts in 1900.


Perhaps Churchward saw the chance of experimenting in the name of Dean, and this somewhat experimental class was not successful, the boiler with its high pressure and 3 ft 6 in (1.067 m) long combustion chamber gave trouble[1] and the long 28-inch (711 mm) stroke of the inside cylinders led to fractures of the solid crank axles.[2] So the class was not long-lived and most were withdrawn around 1906.

Aberdare class[edit]

Their numbers were adopted in 1907 by some of the last batch of the more elegant and reliable Aberdare Class 2-6-0s, which may also have re-used some of the "Kruger"s' parts.[3]
