Regionalzug (R)

Regional trains operate all around Austria, usually connecting smaller towns and villages with the big cities. ÖBB has a number of modern multiple units running these services but still operates some older trains as well. Many trains have air-condition and low-floor entry.

They usually stop at all stations. However in and around Vienna, regional trains are semi-fast trains and do not stop at all stations. In that area, stopping services are provided by "S-Bahn" suburban trains. Around other larger cities, regional trains are usually branded "S-Bahn" nowadays too.

There are several different types of trains. All are 2nd class only.

- Cityjet: electro multiple unit, most modern trains; low-floor, air-condition, power sockets, equipped for persons with reduced mobility, bicycle storage. Wifi on some trains
