The Helsinki commuter railway (Finnish: Pääkaupunkiseudun lähiliikenne/ Swedish: Huvudstadsregionens närtrafik) is the rail system serving Greater Helsinki, Finland. The network is part of the HSL network, and is operated by VR, the Finnish state-owned national railway company. Together with the Helsinki Metro, buses, and trams, the network forms the heart of Helsinki’s public transportation infrastructure.
Interchangeable Tickets Across Services
Trains run primarily above ground in the Helsinki metropolitan area. Within the municipalities of Espoo, Helsinki, Kauniainen, Kerava, Kirkkonummi, and Vantaa, the system uses tickets that are interchangeable with the bus, metro, and tram networks managed by HSL. Traveling beyond Kerava and Kirkkonummi uses VR commuter tickets. HSL’s area is completely within VR zones A, B, and C.
The network is composed of 15 separate services, pictured in the network map below. They operate on four branches of railway lines that all begin, and terminate, at the Helsinki Central railway station. The system has a total of 70 stations, 14 of which are located within the city of Helsinki.
