Stockholm Metro extension


Stockholm is one of the fastest growing metropolitan regions in Europe. The population is increasing by 35,000 a year. Stockholm needs more housing and better public transportation and as a result the Metro is about to be extended they will be adding 20 km of new track and 11 new stations. 

In January 2014, the government, Stockholm County Council (since 01.01.2019 Region Stockholm) and the City of Stockholm, Municipality of Nacka, Jarfalla Municipality and City of Solna signed a mutual agreement on the expansion of the Metro and increased housing construction. The extension of the Metro is the largest investment in public transport in the Stockholm region since the 1970's. The EUR1.58 billion (SEK16.7 billion) investment  will be financed jointly by all the parties concerned, i.e. the State, the County Council and the municipalities that will be served by the Metro. 

The Blue line will be extended:

             4.1 km to Barkarby, with 2 new stations Barkarbystaden and Barkarby,  estimated production cost EUR236,34 million (SEK 2.5 billion);

             4.5 km  to Sodermalm  with  2 new stations at Sofia and Hammarby kanal, estimated production cost: EUR236,34 million (SEK 2.5 billion);

             4.1km to Nacka with  3 new stations at Sickla, Järla and Nacka,  estimated production cost  EUR236,34 million (SEK 2.5 billion);

             2.7 km to Soderort, with 1 new station at Slakthusomradet and 1 new subsurface platform  -70 m beneath the ground surface - at Gullmarsplan, estimated production cost EUR236,34 million (SEK 2.5 billion). 

The present depot at Hogdalen will be expanded with a new workshop, new sidings and a 2.5 km-long railway tunnel that will connect up with the Farsta branch of the Green line. Estimated production cost EUR94.51 million ( SEK 1 billion).

The Yellow line will be extended 4.1km from Odenplan to Arenastaden with 3 new stations at Arenastaden, Sodra Hagalund and Hagastaden, the estimated production cost is EUR349.80 million (SEK 3.7 billion). The new Yellow line will connect with the Green line at Odenplan. The single- and double-track tunnel  will be driven using traditional techniques. Running in parallel with the rail tunnels is a service tunnel, which will also be used for evacuation purposes.

The new stations will have 145 m-long platforms for adaptation to today’s modern Metro trains. The platform width varies from 10 m to 14 m for stations with high passenger flows. The height from the rock bed to the highest point in the platform space is approximately 9 m. The construction will take 6 to 8 years to complete. Approximately 40 contracts will be put out to tender. The last contract will be procured in about 2023 but procurement of the works has already begun, please click here for procurement timetable.
