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 1946, Kurt Wiesinger, professor of engineering at the ETH Zürich, put forward plans for a highspeed train that would have covered the distance between Zürich main station and Oerlikon in two minutes. Architect Wolfgang Nägeli presented a more realistic project in the Schweizerische Bauzeitung in 1947. Several tramlines were to be relocated underground in the city centre. He proposed building a tunnel underneath the Bahnhofsstrasse between Bürkliplatz and the Platzspitz park, along with lines branching off from Paradeplatz to Sihlstrasse and from the main station to Weinbergstrasse. This first draft comprised 2.7 kilometres of tunnels, as well as 0.2 kilometres of ramps and bridges. He calculated the costs would be between 35 and 40 million Swiss Francs. In a second step, he planned a second stage from Weinbergstraße to Beckenhof covering 1.1 kilometres of distance (plus 0.7 kilometres for ramps) and costing another 14 to 18 million Swiss Francs.
