The expansion of the metro is in full swing around the Stockholm area. In H\u00f6gdalen some of the most important work is under way to make the new metro a reality \u2013 here H\u00f6gdalen depot is being expanded to accommodate the new trains inserted on the routes. <\/span><\/p>\n\n\n\n

\u2013 More trains will need to be cleaned, maintained and parked. The depots are incredibly important and if they are not around, the tracks and stations would be empty, as the trains would not be running. The depots are simply the heart pumping around the traffic in the metro network, says Henrik Unosson, project manager for the expansion of the H\u00f6gdalen depot.<\/span><\/p>\n\n\n\n

One of Henrik Unosson\u2019s very first jobs was actually as a technician i H\u00f6gdalen depot during the early 1990s. Since 2018 he has worked for Region Stockholm for the expansion of the same depot.<\/span><\/p>\n\n\n\n

\u2013 It feels cool to be back where I once started, but now with the focus of innovating and expanding.<\/span><\/p>\n\n\n\n

The depot situated in H\u00f6gdalen industrial area was designed by architects Erik Vestergren and Cyril Marcus, and was built in 1957 and 1958. Since then the depot has been expanded and extended on several occasions, and now it is time to do that again.<\/span><\/p>\n\n\n\n

\u2013 Since the construction of the depot it has never been depleted of people. The metro never stops and it needs constant maintenance and cleaning.<\/span><\/p>\n\n\n\n

Henrik Unosson explains that just as cars a metro train needs service after a certain amount of kilometres. Some checks have to take place more frequently, while others are performed at slightly longer intervals. And then there are checks that continuously need fixing, when it is required. For example wheels and brakes underneath the vehicle are checked, and in the passenger area ventilation and interior design is checked in order to ensure a nice environment for the passengers.<\/span><\/p>\n\n\n\n

This is how the expansion is done<\/strong><\/span><\/p>\n\n\n\n

In the depot area, several new buildings will be erected and other buildings will be remodelled. For example, new storage halls will be built, a new cleaning and graffiti removal hall and the existing workshop will be remodelled to fit the new, longer C30 trains. That will be about a doubling of the capacity when the depot can receive around 50 trains, compared to the current 25 trains.<\/span><\/p>\n\n\n\n

A new tunnel will be built from the H\u00f6gdalen depot to H\u00f6kar\u00e4ngen, thereby enabling the depot to receive trains from both the Blue and Green line (the Hags\u00e4tra branch will belong to the Blue line). Adjacent to the tunnel a new storage hall will also be built underground, with space for 11 trains.<\/span><\/p>\n\n\n\n

During the spring of 2021 new work will commence at Kvicksundsv\u00e4gen in H\u00f6gdalen industrial area. At \u00d6rbyleden the construction of the work tunnel to be used during the whole construction phase has begun, to remove rubble and bring in machines and personnel to work on the tunnel with tracks and the storage hall. This autumn preparatory work will also commence next to the Green line metro tracks in H\u00f6kar\u00e4ngen.<\/span><\/p>\n\n\n\n

Operation and expansion at the same time<\/strong><\/span><\/p>\n\n\n\n

\u2013 It is a challenge that the expansion work will take place while the existing depot will remain fully operational. This means that the construction period will be a little longer than it would have been otherwise. And since most of the maintenance work on the metro trains take place at night, most of the construction work will happen during the day, says Henrik Unosson.<\/span><\/p>\n\n\n\n

All the work with the expanded depot in H\u00f6gdalen is estimated to take around 5 years, and people living, working and being nearby will notice the work through e.g., traffic diversions, transports and sounds from drilling and blast work. When the new storage hall and the tunnel with tracks are ready, they will not be evident above ground. <\/span><\/p>\n\n\n\n

Greater capacity and new routes<\/strong><\/span><\/p>\n\n\n\n

When the new metro is complete, it will be possible to have more traffic on both the Hags\u00e4tra and Farsta lines, and passengers in all of Stockholm will be able to take the metro to e.g. Nacka, Arenastaden and Barkarby.<\/span><\/p>\n\n\n\n

\u2013 The expanded depot also means that the entire metro system will be more durable and stable. If something happens in the depot in Rissne, then trains from the H\u00f6gdalen depot can easily be deployed to servicing the Blue line, concludes Henrik Unosson.<\/span><\/p>\n\n\n\n

Background<\/strong><\/span><\/p>\n\n\n\n

Region Stockholm\u2019s metro expansion administration investigated 15 possible depot solution and has since discussed H\u00f6gdalen and Skarpn\u00e4ck as two possible locations. In February 2019 it was decided to expand the existing depot in H\u00f6gdalen. One of the advantages of expanding the H\u00f6gdalen depot is that it will become a depot serving both the Blue and Green line.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"

The new metro is not only new routes and stations. Nothing would work without room to maintain the trains.
