Zurich and its suburbs have an extensive commuter rail system known as the S-Bahn and operated by the Zürcher Verkehrsverbund (ZVV). Coverage is spotty within the city, but there are more than twenty lines servicing the region. The city and its suburbs are split into different "zones". Pricing is based on which zones you are traveling through. One ride can cost anywhere from CHF2 to CHF80.
Tickets must be purchased before boarding the train, or else you could be fined. The ZVV NetzPass refers to monthly and annual cards and are good on all ZVV transportation. The monthly passes can become economical in just a few days if you're using the system extensively. Day passes are also available.
The city's main intercity train station is Zurich Hauptbahnhof. It is the largest and busiest station in Switzerland and has service to the rest of the country and throughout Europe.
