The origins of this car may be at the beginning of the 20th
century when most trains were composed of two or three axle
cars. A lot of those cars (including the well-known three-axle
compartment cars of Prussia) survived the second world war when
there was a shortage of rolling stock that could not be
satisfied with new cars, so the decision was taken to produce
unified three and four axle "rebuilt cars" on the underframes
of the old rolling stock from 1955. Those remained in service
until around 1980, but a lot found a "third life" - rebuilt
again into workshop cars with sleeping compartments for
trackbuilding crews. Throughout the 1980s and 1990s they
could be found on the sidings of many stations, then most
were scrapped. One pair still can be found in 
Weil am Rhein, mostly with preserved 1970s/80s inscription.
