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).
