Data from "Rail Motor Coaches", The Railway Magazine, (15 August 1905), p.136.
Locobase is reminded of the early "oil-electrics" when he looks at the flat-face cab on the front of this steam motor coach in service in the first years of the 20th Century. The coach offered 28 first class seats and 24 second class.
