Kehärata (the Ring Rail Line, previously Marjarata, Swedish: Ringbanan) is a railway route under construction in the area of the city of Vantaa, in the Greater Helsinki Metropolitan Area of Finland. It will connect Helsinki-Vantaa Airport and the adjacent Aviapolis business and retail district to the Helsinki commuter rail network. The line will fill a gap between the existing Vantaankoski railway station and Tikkurila railway stations, travelling in tunnels underneath the airport. The projected cost of the construction is €655 million as of September 2012,[1] up from €605 million in March 2010.[2] The estimated cost of the project in December 2014 was € 738,5 million.[3] The current estimated cost of the project is € 773,8 million[4]

The new line will thus create a connection from the airport to Helsinki Central railway station, as well as the suburban areas on the route. The new railway will leave the mainline going north from Helsinki after Tikkurila station in the east, travel via the airport and into Vantaankoski station to the west, joining the existing the branch line for western Vantaa which is currently served by the "M" train. Five new stations will be built, with space reserved for three more in the future.[1][5] The journey time from the airport to Helsinki Central Railway Station will be about 30 minutes, whilst the time to Tikkurila, to connect with long-distance trains going north or east, will be about 8 minutes.[6]

Present state[edit]

The founding stone of the line was laid on 3 March 2009,[7] and construction was started on 13 May 2009 with the excavation of service tunnels. The excavation of a 300 m long tunnel station under the airport was completed in March 2010, as the construction was proceeding on schedule.[2] The line is to open in mid-2015,[1] a year later than initially planned.[8]

In February 2011, a video on the project's official website stated that the project would be open by June 2014. It announced various new details, including that the station at Tikkurila would be entirely rebuilt as an integrated travel centre, as well as details on the trains that would serve the airport.[9] In September 2012, the opening date was pushed back to July 2015, due to the unexpected need to re-design and reinforce the airport station tunnel to withstand the acidic products of glycol decay by bacteria within the ground.[1] The ground and bedrock at the airport are contaminated by decades of glycol use as an aircraft de-icing agent.

New stations[edit]

In the first phase, five new stations will be built at Vehkala, Kivistö, Aviapolis, Helsinki-Vantaa Airport and Leinelä. Out of these, the Aviapolis and Airport stations will be located in a tunnel. Reservations have been made for three additional stations: Petas (surface), Viinikkala (tunnel) and Ruskeasanta (tunnel).

Future development[edit]

Separate proposals exist to extend the Helsinki Metro to the airport, and to move long-distance services from the current main North-South corridor to a new railway between Pasila and Kerava, passing through the airport. This new route would travel in a long tunnel under the airport and allow direct access from long-distance trains, as well as free the rail capacity taken up by long-distance traffic in the current main corridor for the increasing local commuter traffic.[citation needed]
