S-Bahn ("Schnellbahn") services are suburban trains operating around the larger cities. Originally used only for suburban services in and around Vienna the "S-Bahn" brand is now used for regional trains in and around many state capitals of Austria.
In Vienna, S-Bahn services frequently connect the city centre with the suburbs. Each line usually is operated in intervals of 30 minutes. This results in a very frequent service on the trunk line through Vienna.
Outside of Vienna and Lower Austria you can find S-Bahn trains in the following states:
- Styria (mostly services from/to Graz)
- Carinthia (almost all regional trains)
- Upper Austria (services from/to Linz)
- Salzburg (services from/to Salzburg)
- Tyrol (almost all regional trains)
- Vorarlberg (almost all regional trains)
In these states, regional trains have been branded "S-Bahn" mainly for marketing reasons. Train frequencies can vary between 30 and 60 minutes, sometimes (on weekends and in the evening) even more.
