Wiener Linien, founded in 1999 in its current form and headquartered in Vienna, is the operator of Vienna's U-Bahn metro, tram, and bus network, wholly owned through Wiener Stadtwerke by the City of Vienna. Famous for the 365-euro annual pass that helped quadruple its annual ticket holders, it carries about 900 million journeys a year and continues to expand the U2 and U5 lines.
