The great metro upgrade
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.

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.
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.

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.

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.
