VIE · airport to city
Since 7 September 2026, the choice is no longer simply “regular train versus CAT”. During the main-line closure, CAT is temporarily operating with premium coaches, while S7 and Railjet remain the rail options. The best choice mainly depends on whether you need Wien Mitte, Wien Hauptbahnhof or the easiest onward connection into Vienna’s public-transport network.

What changed with CAT in September 2026
From 7 September 2026, City Airport Train temporarily switched from trains to premium coaches between Vienna Airport and Wien Mitte. CAT states that this temporary arrangement is expected to continue until 31 October 2027.
In this mode, CAT bus runs non-stop in about 21 minutes. Between 7:00 and 19:00 it operates roughly every 12 minutes; outside that period, roughly every 15 minutes. From the airport, the first departures are around 06:10 and the last around 23:37.
The published standard fare is €14.90 one way and €24.90 return. Vienna Airport also currently notes a 20% discount for online CAT-by-bus tickets.
S7: the sensible option for Wien Mitte at a lower price
S7 connects the airport with Wien Mitte in about 25 minutes and the core timetable is roughly every 30 minutes, with additional peak services. For many independent travellers it offers the best balance of cost, predictability and easy interchange to U3, U4 and the wider city network.
Its main disadvantage versus CAT bus is the intermediate stops. But the time difference is small, while the fare difference can be substantial.
Railjet: the straightforward choice for Hauptbahnhof
If your hotel or onward train is around Wien Hauptbahnhof, Railjet is usually the most logical option. Vienna Airport lists a journey time of about 15 minutes and a frequency of roughly 30 minutes. That avoids travelling to Wien Mitte first and then doubling back toward the main station.
Railjet also makes sense if you are continuing to other Austrian destinations because the airport has direct or easy rail connections through Hauptbahnhof.
How much does the cheaper rail option cost?
Vienna Airport lists rail fares from €4.10 to or from Wien Mitte or Wien Hauptbahnhof, including travel on Vienna’s public-transport network under the relevant ticket. Exact pricing depends on the fare and zones, so check ÖBB/VOR immediately before travel.
Rule of thumb: Hauptbahnhof means Railjet. Wien Mitte means compare S7 and CAT bus. If your hotel is on a U-Bahn line, compare total door-to-door travel time rather than the airport leg alone.
What we would choose
For most budget-conscious independent travellers: S7 or Railjet, depending on the neighbourhood. They cost much less and fit naturally into Vienna’s public-transport system.
For someone with heavy luggage who wants the simplest possible trip to Wien Mitte: CAT bus remains convenient, but in late 2026 it is important to know that it is temporarily a coach service rather than a train.
Before you travel
- Check your hotel address and the nearest U-Bahn/S-Bahn stop.
- Check the live timetable on the day of travel, especially for very early or late flights.
- Do not buy CAT automatically because its name says “Airport Train” — during this period the service runs with premium coaches.
- If you will use public transport after arrival, compare the total ticket cost rather than the airport transfer alone.
