Metro
The Helsinki Metro opened in 1982 as the world's northernmost subway line. Particularly by the standards of 20th century metro lines, it is relatively small: Its services operate four-car trains as standard along an east-west route covering the city's waterfront. Its trains and iconography feature a bright orange color palette.The Metro operates two lines that share the same trunk for most of their services. The M1 begins at Kivenlahti and travels eastwards, with the M2 beginning its service at Tapiola. The two lines continue through central Helsinki, underneath its central station and university before diverging at Itäkeskus: The M1 takes a southernly route to Vuosaari, while the M2 follows a northeastern spur to Mellunmäki.
The system's most recent extension opened in 2022, finishing a two-stage western extension towards the adjacent city of Espoo. Several future expansion plans have been thrown around over the years, with a north-south line in various forms being a very common proposal. At present, an eastern extension of the M2 line towards Majvik is pencilled in as a plausible medium-term project, but most of the city's political and infrastructure capital has instead been focused on expanding its tram and light rail network.
Trams
Helsinki's city center possesses a large legacy tram network that remains the largest among the Nordic nations. Although only covering a relatively small section of the overall metropolitan area, the system features 11 lines providing the bulk of local transport provision within central Helsinki. All trams are low-floor, with even older models from the 1970's having received conversions to make them accessible.Multiple extensions of the Tram network are under construction and planning, mostly aimed at adding new routes and redundancy within Helsinki's city center and waterfront. For new tram lines that extend a bit further out of the city's boundary, those are instead classified as...
Light Rail
The newest addition to Helsinki's rail transportation offerings, tram line 15 opened in December 2023 as an orbital line running from Keilaniemi in the west to Itäkeskus in the east, making a wide berth around the edge of Helsinki's core, interchanging with several Metro and Commuter Rail stops as it does so. The route follows the path of the 550 bus, which prior to its replacement was Helsinki's busiest bus line; the light rail now carries five times as many passengers as the 550 bus did.The Light Rail is differentiated from the rest of the tram network by its turquoise branding, unique vehicle livery, and routing which remains mostly off-road and separated from the rest of the tram network. The vehicles are bi-directional, unlike the mono-directional legacy trams (thus negating the need for loops to enable trams to turn around at the end of their lines), but notably share the same 1,000mm narrow gauge track standard, enabling trams and light rail to operate on the same line together in the future.
Several more Light Rail lines are under construction and consideration. The most notable of these is the "Crown Bridges" project, which will construct a trio of tram and pedestrian bridges connecting central Helsinki to the island of Laajasalo to its east. A new Light Rail line, tentatively numbered 12, will use this bridge alongside other legacy tram lines. Another Light Rail line project is dubbed the Vantaa Light Rail, and will run from the Airport to Mellunmäki Metro station via the suburban city of Vantaa, acting as an upgrade for the 570 bus while giving Finland's fourth most-populated city a dedicated local rail service.
Commuter Rail
Helsinki features a relatively expansive commuter rail operation on its national railway lines, using a mix of both local HSL-run services and longer-distance services operated by VR, Finland's national railway company.The Commuter Rail operates a number of service patterns represented by different letters. The services operate on three lines:
- The Rantarata (Coastal Line) connects Helsinki and Turku along its full length; commuter services operate as far as Siuntio, running through the major municipalities of Espoo and Kirkkonummi along the way.
- The Päärata (Main Line) runs as far north as Oulu, with VR commuter services being capable of taking you to Tampere. HSL-operated don't go quite as far, ending at the suburban town of Kerava.
- The Kehärata (Ring Rail Line) is the newest addition, opening in 2015. Previously known as the Martinlaakso line, a commuter-only line that terminated at Vantaankoski. The Ring Rail Line was built as a loop, extending the line from Vantaankoski to the Main Line via Helsinki's airport, allowing commuter services to make runs that begin and terminate at Helsinki's central station.
