Wien Westbahnhof is a major Austrian railway station, the original starting point of the West railway (Westbahn) and a former terminus of international rail services. In 2015, its role changed with the opening of Vienna's new main station and Westbahnhof now is mainly a commuter station and the terminus of private rail operator WESTbahn's intercity service from Salzburg. Locally, Wien Westbahnhof is served by S-Bahn-line S50 and underground lines U3 and U6.
