Grorud Line

The Grorud Line () is a line on the Oslo Metro between Tøyen and Vestli in Oslo, Norway. Running mixed at-grade and through tunnels, it runs through the northern part of Groruddalen, serving such neighborhoods as Grorud, Romsås and Stovner. The line is served by Line 5 of the metro. North of Carl Berners plass, the Ring Line branches off. This section is also served by lines 4 and 6. The line is owned by Kollektivtransportproduksjon and operated by Oslo T-banedrift on contract with Ruter using MX3000 trains. Line 5 runs eight times per hour during the day, while lines 4 and 6 run every 15 minutes. Line 4 only runs northwards, while Line 6 only runs southwards. The line is the busiest branch of the metro, with 40,000 daily riders.

The section from Tøyen to Grorud opened in 1966, as the second branch of the metro. It was extended to Rommen and later Stovner in 1974, and to Vestli in 1975. The Ring Line was opened in 2003. There are plans to extend the line further northwards into Nittedal, and build a branch, the Hasle Line, from between Hasle and Økern to the Ring Line, and a branch to connect the Grorud Line to the Furuset Line.
