2nd-class Compartment-car (B8u, ex-A8u): side-corridor.
When this car was rebuilt into 2nd-class accommodation (1982/1983), compartments were enlarged at the expense of this corridor, so as to make room for 2x4 seats (instead of 2x3 hitherto).
In an attempt to make the side-corridor not too cramped, compartments lost their doors, and thence became semi-open.
