Data from "Steam Rail Motor Coaches, Belgian State Railways," The Locomotive Magazine, Vol XI (14 April 1905), p. 61.
Introduced at the same time as the 6-wheeled steam motor carriage shown in Locobase 10500, this vehicle ran quite a bit bigger. The coach rode on two full bogies, the front one of which was powered; surprisingly the larger vehicle had less cylinder volume and consequently less tractive power. It was outfitted for 1st, 2nd, and 3rd-class passengers and some of their baggage and was rated at 38 mph (61 km/h).
Data from Titre Exposition universelle internationale de 1878 a Paris. Rapports du jury internationale..Volume Groupe VI - Classe 64. Rapport sur le materiel des chemins de fer. p. 50 (cnum.cnam.fr/CGI/fpage.cgi?8XAE277-11.1/54/100/312/0/0 (accessed 1 September 2005).
Again, the jury's report tells us little about this tiny industrial tank. Also, the table on p. 52 shows it to have had a vertical boiler.
