1955–1967: Light rail plan

The initial motion for building a metropolitan railway system in Helsinki was made in September 1955, though during the past five decades the idea of a tunneled urban railway for Helsinki had surfaced several times. A suburban traffic committee was formed under the leadership of Reino Castrén, and in late 1955 the committee set to work on the issue of whether or not there was truly a need for a tunneled public transport system in Helsinki. After nearly four years of work the committee presented its findings to the city council. The findings of the committee were clear: Helsinki needed a metro system built on separate right-of-way. This was the first time the term "metro" was used to describe the planned system. At the time the committee did not yet elaborate on what kind of vehicles should be used on the metro: tram

es were all opes as alternatives. The city council's reaction to the committees presentation was largely apathetic, with several council members stating to the press they didn't understand anything about Castrén's presentation.

Despite the lacklustre reception, Castrén's committee was asked to continue its work, now as the metro committee, although very little funding was provided. In spring 1963 the committee presented its proposal for the Helsinki Metro system. On a technical level this proposal was very different from the system that was finally realised. In the 1963 proposal the metro was planned as a light rail

, compared to the six in the realized system). Castrén committee proposed for the system to be built in five phases, with the first complete by 1969 and the final by 2000, by which time the system would have a total length of 86.5 kilometres (53.7 mi) with 108 stations. This was rejected after lengthy discussions as too extensive. In 1964 the city commissioned experts from Hamburg

1967–1969: Heavy rail plan

In late 1967 Reino Castrén departed Helsinki for Calcutta, where he had been invited as an expert in public transport. Prior to his departure Castrén indicated he planned to return to Helsinki in six months and continue his work as leader of the metro committee. For the duration of Castrén absence Unto Valtanen was appointed as the leader of the committee. However, by the time Castrén returned, Valtonen's position had been made permanent. Following his appointment Valtonen informed the other members of the committee that the plans made under Castrén leadership were outdated, and now the metro would be planned as a heavy rail system in deep tunnels mined into bedrock

The Metro did not immediately win the approval from inhabitants of eastern Helsinki, whose direct bus links to the city centre had now been turned into feeder lines for the Metro. Within six months of the Metro's official opening, a petition signed by 11 000 people demanded the restoration of direct bus links. Subsequently the timetables of the feeder services were adjusted and opposition to the Metro mostly died down.

Safety

Passenger safety instructions are inside train carriages above the doors and stations at ticket hall and platforms. These instructions guide to using emergency phones and also include a emergency phone number to traffic center. There is emergency-stop handles at platforms, which are used to stop the train either arriving or departing in cases such as person trapped between doors, or person fallen onto track. There are emergency brake handles inside the carriage next to the door and at both ends of carriage.

Especially for people with seeing difficulties, all platforms have a yellow line marking the safe area on platform.
Additionally there are fire extinguishers in trains and stations.

, or "western metro") provoked much discussion and political feuding both within Espoo and between the two municipalities. However, according to a poll conducted in 2005, 75% of people in Espoo favoured building the western extension, and in September 2006, the Espoo city council approved the extension.

The construction work started with the excavation work of the tunnels at Ruoholahti in November 2009. Further excavation work started in Lauttasaari and Espoo in May 2010. The extension is expected to be in operation in 2015 at the earliest. (Currently, the metro serves Kamppi

 Ring Rail Line, which connects the airport to the rail network, was begun in May 2009. The current plans commissioned by the city recommend the extension of the tram network, instead of the metro, to Laajasalo. Thus, the construction of the second metro line on a Laajasalo-Kamppi-Airport route appears unlikely.

On 17 May 2006 the Helsinki city council decided that the current, manually driven metro trains will be replaced by automatic ones, operated without drivers. Until this is done, expansion of the system will not be possible as new and replacement parts for the current system, built in the 1970s, are increasingly difficult to obtain. The goal is to have the automatic trains running in 2013.

Unused stations

In addition to the metro stations already in operation, forward-looking design has led to extra facilities being constructed in case they are needed in the future.

Kamppi/Kampen
The current metro station lays in an east-west direction. A second metro station was excavated at the same time of construction in 1981. This station is perpendicular (north-south) to the first one and has platforms 100m in length, slightly shorter than those above. Tunnels designed to eventually connect the two sets of lines curve off from the west-end of Kamppi. See also: Helsingin Sanomat

Munkkivuori/Munkshöjden
The designers of Finland's first shopping centre were very enthusiastic about the rumoured plans for a metro system all over Helsinki—something that would not appear for another 20 years. Built in 1964, the station does not fit into any future metro lines and is unlikely to be used. The platform area is currently partially littered with building-rubble from more recent construction works in the area and the only visible evidence of the ahead-of-its-time station are a pair of large escalators. The escalators lead down from the main part of the shopping mall to the below-ground area where the ticket office would have been. The entrance to the lower level is behind the strange-shaped photographic shop.

 for the metro division of HKL was €16.9 million and it made a profit of €3.8 million.

The Metro is by far the cheapest form of transport in Helsinki to operate, with a cost of only €0.032 per passenger kilometre. The same figure for the second cheapest form - trams - was €0.211.

In 2002, the Metro used 39.8 GWh of electricity, though the figure was rising (from 32.2 GWh in 2001). This equals 0.10 kWh per passenger kilometre, and compares favourably with Helsinki's trams (which used 0.19 kWh per passenger kilometre in 2002).
