North Western Railways 0-2-2 Locomotives in India


Class Details by Steve Llanso of Sweat House Media

Class Steam motor (Locobase 10584)

Data from "Steam Rail Motor Coach, North Western Ry of India", The Railway Magazine, Volume XII [12] (15 September 1906), p. 155. See also "Rail Motor Cars for the Indian North Western (State) Railway System," The Tramway and Railway World, Volume 19 (5 April 1906), p. 308-309.

This steam motor coach was built during the type's brief period of popularity. Like most such vehicles, the locomotive wasn't a permanent part of the carriage, which carried 72 3rd class passengers and their luggage. The locomotive was laid out as a "cab-forward" placed over the single driving axle, which was driven by cylinders set between the drivers and the rear trailer. Specifications called for top speeds of 35 mph (56 kph).
