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).
Limmattal light rail line
When fully open, light rail trains will run every 15 minutes between Zürich-Altstetten and Killwangen-Spreitenbach stations, with the ability to later increase the frequency to every 7.5 minutes. The line will be double-track throughout, and over 90% segregated from road traffic. The stretch of the line between Farbhof and Schlieren will also be used by an extension of Zürich tram route 2, running every 7.5 minutes and replacing the existing Zürich trolleybus route 31 over that stretch. The Limmattal and Bremgarten–Dietikon lines will also share a short section of track on the existing alignment of the latter in the centre of Dietikon.
