A low-floor truck transport wagon of the Swiss HUPAC company. It has
16 very small wheels, so the floor is low enough that trucks do not
exceed the loading gauge. These cars operate in fixed consists with
special couplers between the cars and normal couplers with buffers on 
the ends. The trains operate every night between Freiburg (Breisgau)
and Milano, the truck drivers sleep in a rebuilt passenger car coupled
to the train. April 1996, Freiburg (Breisgau) freight station.
