Great Central 2-4-2 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 13576)

Data from "The Engines for working the London Extension of the M Sheffield & L Ry", The Railway Engineer, Volume XVI, No 6 ( June 1895), p. 169. Works numbers were 3694-3703.

This class of radial tanks was designed by Harry Pollitt for the suburban services to London. Like the goods engines awarded to Beyer, Peacock at the same time (Locobase 13577), these had Belpaire fireboxes. Although they were ordered at the same time and assigned the lowest boiler numbers, they were in fact completed after all of the goods engines were delivered. By then, the MS & L had acquired its new identity as the Great Central Railway.
