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.
Zürich S-Bahn
Following further work and the enactment of a new transport act, the regional public transport authorities presented a new proposal for a combined regional U-Bahn and S-Bahn system, with the latter being a railway network centred on a tunnel under the city centre, which would connect to existing suburban railway lines. From Zürich Airport, an U-Bahn line would run via Glattbrugg, Oerlikon, Hirschenwiesen, Central, Zürich Hauptbahnhof, Stauffacher and Altstetten to Dietikon. Much of the line would have run above ground. The second part of the proposal was the "Zürichberg network", a line from Zürich Hauptbahnhof via a new tunnel under the Zürichberg to Dietlikon to the northeast (not to be confused with Dietikon, which lies to the west of Zürich). The proposed construction of an underground station in Museumstrasse on the north side of the Hauptbahnhof was intended to ease the pressure on the Hauptbahnhof. On 20 May 1973 this proposal was rejected in a referendum, with the "no" vote as high as in the previous referendum. At the referendum, little opposition had been expressed against the proposed S-Bahn lines.
