The system contains 2 lines (M1 and M2)[4] with 30 stations along a total length of 43 kilometres (27 mi), running from southern Espoo via central Helsinki to the East Helsinki suburbs.[5] 21 of the stations are located in tunnels, including every station west of Sörnäinen as well as Puotila and Itäkeskus.[6] Every other station is on the surface or elevated. The Länsimetro extension continues the line into western Helsinki and the neighbouring municipality of Espoo.[6] The system has two depots, located in Roihupelto, Helsinki and Sammalvuori, Espoo.[6][7]
These are the stations on the current metro line. The names are listed first in Finnish, then in Swedish (and English, if applicable1). Bus transfers are not listed.
An eastern extension is currently being planned, with construction being slated to start in the early 2030s. The currently prevailing proposal extends the metro eastwards from the current terminus at Mellunmäki, with proposed stations in Länsisalmi in Vantaa and Salmenkallio, Östersundom and Sakarinmäki in Helsinki, terminating at Majvik in Sipoo.[9] Four of the stations would be underground. Other possible stations include Vantaa's Länsimäki and Helsinki's Gumböle. The municipality of Sipoo has also explored other routes and possible further extensions, to Sibbesborg and Eriksnäs.
A tunnel for the first metro station in Helsinki was dug in 1964 under Munkkivuori shopping center in concordance with the city's first light rail-based metro plans.[10] These would have produced of a network of over 90 kilometres (56 mi).[10][11] No metro line has ever reached this unfinished station, consisting of 0.5 km (0.31 mi) long tunnels[citation needed] dug in bedrock. There are no plans of connecting the station to the existing network.[10] The tunnel was flooded due to a water pipe breakage in January 2010, two months after a similar incident at the Rautatientori station.[12][13]
