Bucuresti, Romania
R.A.T.B. (Regia Autonoma de Transport Bucuresti)
Rathgeber M5.65 #2525 - ex-Munich #2525
Coupling adaptor: at one end is the "Tatra type" couple (adopted in the '70s, when the first Tatra T4R cars were imported) and at the other end is the old coupling system used until the '70s, but that can still be found on some freight trailers.
