Arrival at the airport (Zurich Kloten)
After reclaiming baggage, follow the signs “Bahn/Railway" to ticket counters and machines. There are English instructions on the machines; follow them or simply press the left (red) key at the bottom where it says “Zurich City". The machines accept cash as well as debit/credit cards. A single journey ticket is valid during 2 hours after purchase for any train to Zurich City Centre as well as for any trams and buses in the City Centre. If you plan to stay the whole day, a day ticket (valid 24 hours) is more suitable. Take an escalator down to the platforms 3 or 4. Trains to city centre leave approx. every 10 minutes and take about 10 minutes to reach main station (Zurich HB).
Arrival at Zurich Main Station (Hauptbahnhof – HB)
At the main station walk to the head of the train and follow any signs to “Bahnhofstrasse", where you can take tram 6 or 10.
