This curious machine resembled a type 230 tank engine, without coupling rods. The side water tanks are cut away above the leading bissel truck to allow room for the cylinders of a V12 high-speed steam engine, which drove the first two axles through reduction gearing; the rearmost wheel was not driven. The boiler and superheater were conventional. This machine did not give satisfaction on the test bench at Vitry and it was planned to rebuild it. info and first image from http://douglas-self.com/MUSEUM/LOCOLOCO/steamotor/steamotor.htm#221
