Ring Line (Oslo) - Route

Route

The 5.0-kilometer (3.1 mi) Ring Line branches off from the Sognsvann Line after Ullevål stadion, just before Berg. It immediately enters a tunnel that runs via Nydalen to Storo. The station at Storo is just outside the entrance to the tunnel. From Storo to Sinsen, the tracks are laid parallel to the Gjøvik Line of the mainland railway. Also the Sinsen Line of the Oslo Tramway and the Ring 3 motorway follow the same corridor between the two stations. The section between Ullevål stadion and Storo is 3.3 kilometers (2.1 mi), while the section from Storo to Carl Berners plass is 1.7 kilometers (1.1 mi). Of these, 4.0 kilometers (2.5 mi) are in tunnels.

Nydalen is a neighborhood that has undergone an urban redevelopment after it formerly was an industrial area. The immediate vicinity of the station has several large working places. In 2005, BI, with 8000 students and faculty, moved into a new campus across the street from Nydalen Station. Nydalen is the only underground station on the Ring Line. The escalators leading down to the platform features The Tunnel of Light, an artistic presentation of sound and color around the riders as they ascend from or to descend to the station. The artwork contains 1800 lights and 44 speakers. Nydalen also serves as a bus hub.

Storo opened as a tram station as part of the Grünerløkka–Torshov Line on 28 November 1902. It is located about 200 meters from Grefsen Station of the Gjøvik Line. The Norwegian National Rail Administration is planning to move the station platform so there can be direct transfer between NSB Gjøvikbanen's commuter rail services, and the metro. Storo functions as a bus and tram hub; it serves line 11 and 12 on the Grünerløkka–Torshov- and Kjelsås Line, and line 13 on the Sinsen Line.

Sinsen opened on 20 August 2006, three years after the two other stations. The station is located close to, but not adjacent, to the tram stop Sinsenkrysset on the Sinsen Line (tram no. 17). Located at the interchange between Ring 3 and Trondheimsveien, it also serves as a bus hub.

The Løren Line is a proposed connection that would connect the Ring and Grorud Line. It would split from the Ring Line south of Sinsen, and run part in tunnel and part at-grade until it connects to the Grorud Line west of Økern. In the tunnel section the new station, Løren, would be built. The day section would run parallel to part of the mainline Alnabru–Grefsen Line. The line will allow metro trains to run directly from the Grorud Line to the Ring Line, and thus pass from east to west without passing through the packed Common Tunnel. It is part of the political compromise Oslo Package 3, and estimated to be completed by 2017.
