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 Underground Railway
Zurich Airport would have been the northern terminus. Under the Butzenbüel and Holberg hills, the route would have led to the overground station Werft, where a short branch line from the train station Kloten would have terminated. Subsequently, the underground was to proceed parallel to the existing SBB line from Opfikon to just after the Eisfeldstrasse station. There, the northern portal of the tunnel section was to be located. Following Ohmstrasse and Schaffhauserstrasse, the intersection at Hirschwiesen would have been reached (in the area of the Milchbuck tram stop). Here, 30 metres below the surface, two station tubes connected by cross passages were to be built, the western one for trains on the trunk line and the eastern one for trains from and to Schwamendingen. The Schwamendingen branch line was to proceed partly underneath the Schöneich Tunnel of the planned motorway approach road A1L, and was to end at Hirschenplatz for the time being. From Hirschwiesen, the line would have reached Zürich Hauptbahnhof by means of a broadly shaped S-curve, crossing beneath the Milchbuck Tunnel, the Letten Tunnel and the Limmat.
