This is one of the TEE INOX PBA coaches as they have been ordered
by the French (SNCF) and Belgian (NMBS/SNCB) railways in the
sixties. The SNCB/NMBS owns all open plan coaches, the SNCF the 
compartment, restaurant, bar and generator carriages. Originally
they were all 1st class, some have been converted to 2nd class
(with a green stripe above the windows). These coaches have been
used in TEE and later EC trains between Paris, Brussels and
Amsterdam. Currently they are being replaced by TGVs.
