Data from "Rail Motor Coaches", The Railway Magazine, (15 August 1905), p.136.
This short-wheelbase combination vehicle had seats for 40 passengers and a vertical, superheated boiler. It was rated at 60 kph (37 1/2 mph) cab-first and 50 kph (31 1/2 mph) running cab-last. The coach could pull two more trailer cars for a total of 30 tons trailing load.
