Timetables and travel information can be found directly at:
Austrian Federal Railways (ÖBB),
Steiermärkische Landesbahnen (STLB),
www.busbahnbim.at.
With the BusBahnBim app from Verbundlinie, timetable information has never been easier: all bus, train and streetcar connections in Austria can be queried by entering locations and/or addresses, stops or important points. The app is available as a free app for smartphones (Android, iOS) - on Google Play and in the App Store.
The Thermenlandbus also takes you directly to Fürstenfeld on the fastest route.
