Data from "Steam Motor Car for the Erie & Wyoming Valley", Railroad Gazette, Volume XXXI [31], No 5 (3 February 1899), p. 83, and "Steam Motor Cars for Railway Service, Cooke Steam Car - Erie & Wyoming Valley RR", Engineering News and American Railway Journal, Volume XLVII [47], No 6 (6 February 1902), p. 105. ( (Many thanks to Chris Hohl for his extensive research and his 3 December 2018 email, spreadsheet, and article link. Chris particularly cites Ron Goldfeder for his article, "The Inspection Locomotive." Railroad History. Spring-Summer 2012.

If Delaware & Hudson's "Transit" (Locobase 11154) seemed small to Locobase, this "steam motor car" was a jewel box. It looked like a severely bobbed tram car, its bulky clerestory covering a coach body less than 20 feet long. The front section contained four seats and a couch. A short passage alongside the toilet compartment led to the rear section holding the boiler, small coal bin, and operator's station.
