Zürich Seebach railway station
Trains on the S6 provide a half-hourly connection to Zürich Hauptbahnhof station, taking 12 minutes for the journey via the southern connector and Oerlikon station. In the opposite direction, S6 trains continue to Baden station, taking 28 minutes for the journey. The station also sees significant through freight traffic, most of which takes the Furttal line in order to avoid passing through central Zürich, using the northern connector onto or off the Zürich–Winterthur line.
Rail 2000
In parallel with the Rail 2000 projects, the NRLA project is upgrading the two major railway lines through the Swiss Alps: the Gotthard railway (including the new Gotthard Base Tunnel and the Ceneri Base Tunnel) and Lötschberg line (including the new Lötschberg Base Tunnel). The upgrade of Gotthard will shorten the journey between German-speaking Switzerland and Ticino by an hour. The Lötschberg base tunnel was opened in 2007, making a trip from Zürich to the canton of Valais in less than two hours possible; it has shortened the journey between Bern and Brig and Italy by about a quarter of an hour.
