Vienna has a well-developed public transport network. Buses, trains, trams and underground lines will take you almost anywhere in the city in no time at all. Vienna public transport Wiener Linien operates five underground lines, 31 tram and 80 bus lines, of which 21 are night lines. Night lines only operate between 0.30 am and 5 am. The Wiener Linien vehicle fleet currently consists of 600 tramcars and 500 buses.

Vienna public transport is part of the Verkehrsverbund Ost-Region VOR (transport association for Austria's eastern regions). Verkehrsverbund Ost-Region is split into eight zones and includes parts of Lower Austria, the Burgenland and all of Vienna. The city of Vienna accounts for one full zone or core zone (Kernzone or "Zone 100"). A single ticket is valid for travelling one way in one zone. You may change to different lines in the course, but you may not interrupt your journey. Single tickets can be purchased at a price of EUR 1.70.

Validated tickets can be used for all public transport in the core zone. Tickets are available at ticket machines at most underground stations or at points of advance sale. Tobacconists also sell tickets. You may also purchase a ticket on board the bus or tram at an increased rate of two Euro per ticket.

Apart from single tickets there are passes for longer periods of time. Passes are available for 24 hours and 72 hours, or as weekly, monthly or annual passes.

Tickets must be validated before boarding. To validate your ticket stamp the ticket at the blue machines located at the entrance of underground stations as well as on buses and trams. Tickets bought directly from the tram or bus driver are automatically validated and need not be stamped again.
