Metro upgrades in 2025: How to travel

Several major upgrades will be made to the Metro network in 2025. During certain periods, buses will replace metro services on several routes, and Majorstuen station will be closed for parts of the year. Here’s how your journey might be affected.

Why is the Metro being upgraded?

The Metro system is undergoing upgrades to provide you with faster journeys and more frequent departures. That’s why we call the project “Det store T-baneløftet”. The upgrade consists of three major projects:

  • Upgrading Majorstuen station
  • Connecting the Fornebu line to the existing metro network
  • Installing a new signalling and safety system (CBTC)

Sporveien and Fornebubanen are carrying out the work, which will give Oslo a more modern and efficient Metro network.

Which Metro routes will be closed, and when?

Here are the important dates to note in 2025. Please be aware that changes may occur, and we will update the schedule continuously.

News! Check out our new interactive Metro map. It’s now easier for you to see how the upgrade will affect your specific line throughout the year.

What does this mean for you as a traveller?

Some lines will be temporarily closed, and buses will replace Metro services on affected routes. We understand this may cause inconvenience to your daily travel, and we are working hard to provide reliable alternative transport during every phase of the upgrades.
Travellers will receive information about replacement services in good time. Details will be available in the Ruter app and on our website.
