There is a tourist information office in the arrivals area of terminal B, where transcontinental flights arrive. There is also a tourist office in the central rail station, the Hauptbahnhof. TAXI Taxis are available outside the arrivals hall.
Trains leave directly from the airport rail station, which is underneath the airport.
It is a short walk from the arrivals area. There are also direct trains to many Swiss cities such as Bern, Lucerne, Interlaken, Geneva, Chur, and others. Along with Geneva and the London Gatwick Express, this is probably the best airport transportation in the world. Before you rent a car look at the train service. For cities like Bern where a car is not needed, the frequently departing train will put you in the center of the city.
