A project group with members of the Norwegian Public Roads Administration and the National Rail Administration have proposed that instead of rebuilding the Ulriken Tunnel to double track, a new double-track light rail tunnel could be built from the city center to Arna. This would allow the light rail line to replace the two-station Bergen Commuter Rail service, and give better access to the city center for people from Arna. Several politicians, including the majority in Hordaland County Council, have stated that in the long run they want the light rail line extended northwards to Knarvik and westwards to Straume and Kleppestø.
