The Berliner Verkehrsbetriebe (German: 'Berlin Transport Company') is the main public transport company of Berlin, the capital city of Germany. It manages the city's U-Bahn underground railway, tram, bus, replacement services (Ersatzverkehr, EV) and ferry networks, but not the S-Bahn urban rail system. The generally used abbreviation, BVG, has been retained from the company's original name, Berliner Verkehrs-Aktiengesellschaft (Berlin Transportation Stock Company). Subsequently, the company was renamed Berliner Verkehrs-Betriebe. During the division of Berlin, the BVG was split between BVG (Berliner Verkehrsbetriebe Gesellschaft in West Berlin) and BVB (Berliner Verkehrsbetriebe in East Berlin, also known as the Volkseigenes Kombinat Berliner Verkehrsbetriebe, BVB). After reunification, the current formal name was adopted.
