The Vienna S-Bahn (from Floridsdorf Station) and (reverse direction) line stops at the airport. The more expensive (City Airport Train) connects the airport directly to the Wien Mitte station close to the city center, where S-Bahn trains also stop but take a slightly longer time because of 7 intermediate stops. There are also many buses from the airport to various places in Vienna and to other cities; however, the S-Bahn line is the only means of transport from Vienna to the airport on which the standard integrated tickets for the Vienna region are valid (as a result, they also allow further travelling by underground, bus or tram, which the CAT tickets don't).

After the construction of Main Railway Station, a line called "S70" is scheduled to be opened which will connect the airport to that railway station, so that the frequency of S-Bahn trains becomes higher than the current 30 minutes. There are no plans to extend any underground line to the airport although it has sometimes been proposed to extend line U3 (currently terminating at Simmering) there; this would be the first underground line extending beyond Vienna's borders.
