Comparison between DBNachtZug couchette car Bcvmh (left) and FS compartment car AB (right). Both of these cars are built according to the UIC-X standards and both have a similar roof shape, but you can see detail differences between the folding doors (including steps: two or three), bogies (Minden-Deutz or Fiat) and sliding windows (visible rivets on the FS car).
