Winterthur railway station
Winterthur is Switzerland's fifth busiest station, and is a major node between Switzerland's largest railway nucleus in Zürich and places in Eastern Switzerland (such as St. Gallen and Schaffhausen), as well as Germany (Munich), and Austria (Vorarlberg). The station is served by trains on Zürich's suburban S-Bahn network, as well as by regional and intercity trains, with most through passenger trains making a stop. It is also connected with Zürich's airport railway station Zürich Flughafen, which can be reached in about 15 minutes about every 8 minutes. Zürich Hauptbahnhof can be reached with up to 16 direct connections per hour and the fastest connection takes only 22 minutes (S12). The station has 9 standard gauge platforms (numbered 1-9).
Konstanz station
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. In the long term, a half-hourly service is to be established.
