Current project

Project Extension of Stockholm Metro 

What: Stockholm's metro network will be extended by almost 20 kilometers new tracks and 11 new stations. In addition, the maintenance capacity of the exiting depot in Högdalen is expanded, where the existing depot is expanded to serve both Green and Blue lines.

Why: Stockholm is growing and it is estimated to be 2.6 million inhabitants in the county in 2025. In order to meet the growth, major investments are being made in the expansion of public transport. In January 2014, the Stockholm Agreement was signed, and agreement between Järfälla, Nacka, Solna, Stockholm, the state and Stockholm County Council to build a whole new line from Odenplan to Arenastaden, extend the Blue Line towards Nacka and South, and expand the Blue Lina from Akalla to Barkarby station. The agreement also includes a commitment for the muncipalities to build 82,000 homes in connection with the new subway.

The Stockholm County Counsil's Extended metro administration is responsible for implementing the subway. In connection with that, we will also expand the existing depot in Högdalen. The entire venture is both decided and funded.

When: According to the plans, construction will start in 2018 for most projects and the design of tunnels, entrances and depot capacity is in progress. We will now start procurement of our contracts, which is about 30 contractors divided into 6 expansion projects. The contracts mainly concern work/access tunnels, maintunnels and construction and installation work for the new stations. Procurement of these works will mainly be carried out during the period 2018-2022.

Cost: Varying from about SEK 30 million to 1.5 billion.

Main projects:

  • Arenstaden: About 4 km new track and three new stations. The whole line will be underground. Approx Rock: 800 000 m3 and Concrete: 37 000 m3. Maximal cost according to funding agreement is SEK 5.9 billion.
  • Barkarby: Two new stations and about 4 km new track. Approx Rock: 710 000 m3 and Concrete: 32 000 m3. Maximal cost according to funding agreement is SEK 3.3 billion.
  • Depot: 2.5 km connecting track, new train hall, extension of workshop building, adaptation of washing and graffiti removal facilities, new connection track in a tunnel etc. Rock: 20 000 m3. Maximum cost according to agreement: SEK 1.6 billion.
  • Nacka, Södermalm and söderort: Blue line will be extended, with a branch to Nacka. This extension is divided into two projects (Södermalm and Nacka). The existing branch to Hagsätra will be rebuilt with a new station at Slakthusområdet and new platform at Gullmarsplan. This part is called project Söderort. About 11 km of new track and six stations. Approx: 2 100 000 m3 rock and 160 000 m3 concrete is three of the extension projects.

Project Mälarbanan

What: Expansion of 20 km of railway, from two to four tracks on the Mälaren Line from Stockholm-Tomteboda to Kallhäll. New construction of three, and rebuilding of two, commuter stations. New bridges and tunnels across the railroad along the entire route, both for cars and pedestrians. Partly submerged railroad in Sundbyberg and Solna. Railway bridges connecting the Mälaren Line with the City line in Tomteboda.

Why: To increase railroad capacity, two additional tracks are built exclusively for commuter trains. This will leave the two outer tracks free for faster traffic, such as freight and long distance trains. By avoiding for faster trains getting stuck behind slower, the accessibility and functionality of the line increases.

When: Construction started in 2012, and parts of the route are already completed and taken into operation. Construction is in progress between Spånga and Barkarby. Preparatory works between Huvudsta and Duvbo is scheduled to begin in 2018. The main contract for tunnels and troughs in Sundbyberg/Solna will start construction no earlier than 2020, with a construction period of 8 years.

Cost: SEK 17 billion (adjusted for inflation from 2016). 

Project The East Link 

What: A new double-track railway Järna-Linköping for trains with speeds up to 320 km/h.

Why: Shorter travel times, increased capacity for more trains, regional expansion.

When: The Swedish Transport Administration is preparing the application for permissibility in accordance with the Enviromental Code. The East Link will be fully operational by 2028.

Cost: SEK 55 billion (2015 price level).
