Which metro lines are closing, and when?

Some lines will be closed, and a replacement bus service will be provided for the metro on the affected routes. We understand that this may create challenges in your daily commute, and we are working hard to offer you a good alternative throughout all phases of the upgrade.

See how the upgrade affects your specific line and itinerary throughout the year.

Detailed overview

There are no planned disruptions on the metro in December. We will keep this section updated with upcoming disruptions for 2026.

Why is the metro being upgraded?

The metro is being upgraded to provide you with faster travel and more frequent departures. That's why we call the project 'The great metro upgrade'. The upgrade consists of three major projects:

• Upgrade of Majorstuen station
• Connection of the Fornebu Line to the existing metro network
• Installation of new signaling and interlocking system (CBTC)

Sporveien and Fornebubanen are carrying out the work, which will provide Oslo with a more modern and efficient metro network.

Stortinget station is open again from December 2nd

Upgrade work meant that from November 4th through December 1st, trains passed by Stortinget station. The station is now open again.

Majorstuen Station

Majorstuen is one of the most important stations on the Oslo Metro. The upgrade will make it easier to travel, allow for more departures, and increase capacity.

The new station will receive

• larger platforms with more space
• multiple accesses to the station
• a new pedestrian and bicycle bridge for safer and faster crossing

With the new signaling system, the upgrades will facilitate a capacity of 36-40 trains per hour in each direction through the downtown tunnel.

Fornebu Line

The Fornebubanen is a new metro line from Fornebu to Majorstuen, via Lysaker and Skøyen. When the line is connected to the current metro network, travelers will have a direct route between Fornebu and Oslo. This will strengthen public transport options, relieve car traffic in the area, and provide more people with an environmentally friendly travel alternative.

New signaling and control system (CBTC)

Sporveien is installing a new digital signal and safety system called CBTC (Communication-Based Train Control). This will allow trains to run closer together and more frequently, providing passengers with more departures.
