Zurich Airport
Zürich Airport railway station is located underneath the "Airport Centre". The station has frequent Zürich S-Bahn services, plus direct InterRegio, InterCity, and Eurocity services, to many places including Basel, Bern, Biel/Bienne, Brig, Geneva, Konstanz, Lausanne, Lucerne, Munich, Romanshorn, St. Gallen, and Winterthur. There are some 13 trains per hour to Zürich Hauptbahnhof, Zürich's main city centre station, with a journey time of between 10 and 15 minutes. By changing trains at Hauptbahnhof, most other places in Switzerland can be reached in a few hours.
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.
