The Bucharest Articulated Tramcar series is a series of tram vehicles produced between 1971 and 1992 by URAC, the main workshops of the Bucharest Transit Company (Întreprinderea de Transport București (ITB)). Various modernized variants have also been delivered since 1993. For the last 50 years they have been the backbone of the tram network in Bucharest, replacing motor-trailer formations that had run in the city since the introduction of electric trams.
