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).
