S7 is an electrified commuter rail service operating between Floridsdorf and Vienna International Airport, with extended eastbound service to Wolfsthal in the greater Vienna area and northbound service to Laa an der Thaya, sometimes ending in Wolkersdorf and Mistelbach. Between Wien Mitte and the airport, S7 provides local service on the route while the City Airport Train provides non stop express service to the airport. The S7 uses the former Aspangbahn right-of-way in the city center then, at Kledering, transitions to the former Pressburger Bahn, which connected Vienna and Bratislava, to Wolfsthal. Average travel time between Floridsdorf and Vienna International Airport is 37 minutes.
