Helsinki's transit system consists of buses, the underground Metro, trams and local trains, plus ferries to the tourist islands that leave from Market Square. The entire system runs frequent departures.
Equipment is clean and efficient.
The Metro has one line and trains run every five minutes, less frequently in the evenings and on Sundays. Timetables and route maps are available from all HKL ticket offices, one of which is located in the central Rautatientori metro station. For the metro and local trains, use the automated ticket vending machines. Bus and tram drivers sell tickets, which you must stamp yourself. If you board public transportation without a ticket, you may be fined regardless of the fact that you are a foreigner.
