13 times a day InterRegio trains run from Biel to Konstanz, which also stop at Zurich Hauptbahnhof and Zürich airport. Until the new 2008 timetable, these trains were composed of ICN tilting electrical multiple units.Konstanz is served hourly by Regional-Express trains on the Black Forest Railway. Until the timetable change in 2015, Interregio-Express and RE trains alternated from Kreuzlingen or Konstanz to Karlsruhe. This was changed with the timetable change, so that there is now a continuous RE hourly to Karlsruhe. The SBB and its subsidiaries SBB GmbH, which has its head office in Konstanz, serves Konstanz with the "Seehas" regional service every half hour. Its subsidiary Thurbo connects Constance and Kreuzlingen every half hour with the S 14, which runs once a hour via Kreuzlingen to Weinfelden.
