The proposed new line is called Pisara – Finnish for droplet – to reflect its shape. The line is designed to connect rail transport hubs around the Töölö Bay area.
The three proposed Pisara stations would be located in Hakaniemi, the city centre and Töölö. According to preliminary plans, the length of the line would be 7.2km, 6km of it underground. The underground section would be served by two parallel rail tunnels, linked by connecting tunnels at 200m intervals.
Helsinki City Council aims to decide on the Pisara local plan in 2014. The realisation of the plan also requires approval by the Finnish Transport Agency.
