The steam-powered railbus had a B'2' wheel arrangement, one axle pair being driven by connecting rods. It had a transverse boiler and a gross service weight of 28 tonnes. Its Stephenson valve gear and brakes were accessible at both ends. The coach had 67 seats on two floors, the second class seating being on the lower level and the third class being split between both levels.
The vehicle was a one-off and was only in service for a short time.
