Vienna public transport is part of the verkehrsverbund ost-region vor (transport association for austrias eastern regions) including 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 ). the vienna card (includes various tourism discounts) note that face masks are currently required on public transport (at the time of writing) how the system works. The four main forms of transport are u-bahn (subway), schnellbahn or s-bahn (local train), straßenbahn and autobus (bus). The five subway lines, 28 tram lines and 129 bus lines bring you quickly and reliably to your destination. See how much it costs to travel on viennas public transport system and see how to save money on the metro, trams and buses. Vienna has, simply put, the finest public transport system in europe. Well, ok - thats difficult to prove, but it certainly scores highly on all counts. A network of bus and tram routes combines with an underground (subway) system that is still being developed and extended and suburban rail lines extend some way into the countryside.
