The new Wien Hauptbahnhof (central station) opened in 2014. Among many new connections are the ICE high speed trains from Linz via the Hauptbahnhof station to Vienna airport, every two hours or so; these can also be used to get to and from the airport in under 20 minutes. Train tickets can be bought at all stations, but are best booked in advance on the bilingual ÖBB website, where significant reductions are available if you book well in advance.
