Common Tunnel

The Sognsvann Line (Norwegian: Sognsvannsbanen) is a rapid transit line on the Oslo Metro of Norway. It branches from the Common Tunnel at Majorstuen and runs 6.0 kilometers (3.7 mi) to Sognsvann. After Ullevål stadion, the Ring Line branches off. The Sognsvann Line serves the northwestern and northern neighborhoods of Oslo, mostly within the borough of Nordre Aker. The line is owned and maintained by Kollektivtransportproduksjon and has nine stations. The western end of line 5 serves the entire line. Line 4 and the eastern end of line 5 serve the southern part of the line up to Ullevål stadion before branching off and continuing along the Ring Line. This gives an average five-minute headway on the southern part and an average fifteen-minute headway on the northern part of the line.

The line opened on 10 October 1934 as a light rail. In 1993, it was upgraded to metro standard as the first light rail west of Oslo, with two stations being closed. The Ring Line opened in 2003. Forskningsparken has transfer to the Oslo Tramway and serves Rikshospitalet. Forskningsparken and Blindern both serve the University of Oslo, while Ullevål stadion serves Norway's largest football venue. North of there the line mainly serves residential areas. Sognsvann serves the Norwegian School of Sport Sciences and the recreational area Nordmarka.
