Data from "Motor Carriages for Railways," The Locomotive Magazine, Vol X (15 October 1904), p. 178; and "Steam Railway Motor Cars with Detachable Engines", Engineering News, Volume LIII [53], No 18 (4 May 1905), p. 463. See also "Combination Locomotive Car to be Tested on the Glasgow & Southwestern Railroad", Popular Mechanics, Volume 6, No 12 (December 1904), p. 1226.
Locobase doesn't have a great deal of information on this James Manson design. The assembly consisted of a small locomotive constructed independent of the carriage, but whose four driven wheels also provided the coach's front bogie. Unlike many such carriages, this car had "uniclass" seating for 50 in two compartments.
At the time of the article in late 1904, the car had just started local service between Mauchline and Catrine in the southwest. (Mauchline lay 32 miles south of Glasgow, 72 miles west-southwest of Edinburgh.)
