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
In December 2015 two members of local government from the Green Party formally demanded that the government produce a report on the possibilities for an underground network in the area of Zürich. They did not make concrete suggestions as to where exactly the tracks should run, but were adamant that the main station should not be included, in view of the enormous amount of traffic it was already carrying.
