Vienna U-Bahn

The Vienna U-Bahn is a rapid transit system serving the city of Vienna. It has five lines covering 83.1 kilometres of route and 109 stations. In 2019 it carried 459.8 million passengers. The modern U-Bahn opened in 1978, though parts of lines U4 and U6 date back to the Stadtbahn system of 1898. Sections of U2 and U6 began as tunnels for earlier tram lines. Only U1 and U3 were built entirely as new subways. The network is integrated with Vienna’s other public transport under the VOR ticketing scheme. Local tickets also cover S-Bahn services run by the national railway operator. They do not apply to airport buses or the express train to the airport. Since 2010 there has been 24-hour service on Friday and Saturday evenings at 15-minute intervals. NightLine buses supplement the U-Bahn on those nights. Stations are often named after streets, squares or districts. Some bear the names of prominent buildings nearby. The Wiener Linien prefer not to name stations directly after buildings. The U5 line is currently under construction and will extend the network to 90 kilometres with 116 stations once completed. Otto Wagner’s Jugendstil stations from the Stadtbahn era remain in use today.
