Expanded depot in Högdalen

We are expanding and modernising the metro depot in Högdalen to accommodate more trains as Stockholm’s metro system grows. Additionally, we are constructing a new tunnel to connect the depot to the Farsta metro branch. The project will be completed in 2026.

The map shows the planned expansion of the Högdalen depot.

Background

The trains in Stockholm’s metro system need to be cleaned, repaired and stored for the night. All of this is done at depots. Stockholm has six depots for the metro system. The current depot capacity will be insufficient once the metro network has been expanded. As a result, in 2016 the County Council Executive Committee decided that the Högdalen depot should be expanded.

The Stockholm metro network is being expanded with 18 stations and 30 kilometers of new tracks. (Click on the image to enlarge)

Larger depot in Högdalen

The Högdalen depot will be complemented with new storage, cleaning and graffiti removal facilities for trains. The new depot will be able to accommodate about 50 trains. This is twice as many as the current 25-train capacity. To make space for the expansion, the compound is being extended about 30 metres south.

We are building a new tunnel

A new tunnel will be built between the Högdalen depot and Hökarängen to provide access for trains from the Green line. The tunnel will measure 2.5 kilometres in length and the blasting work will take about three years. An underground train yard will also be built adjacent to the tunnel with enough space for several trains.

South of Hökarängen station trains will be able to take the new tunnel to the depot.
