The Grorud Line (Norwegian: Grorudbanen) is a 13.0-kilometer long (8.1 mi) line on the Oslo Metro between Tøyen and Vestli in Oslo, Norway. Built as a mix of underground, at ground level and as an elevated line, it runs through the northern part of Groruddalen, serving such neighborhoods as Grorud, Romsås and Stovner. Line 5 runs along the line eight times per hour. The westernmost part of the line, from Tøyen to Carl Berners plass, is also used by Line 6, which continues along the Ring Line. The two will be connected via the Løren Line when construction concludes. With 40,000 daily riders, the Grorud Line is the busiest branch of the metro.
Proposals for an urban railway through the upper parts of Groruddalen were first articulated in public documents in 1919. Planning started in the late 1940s and the line was politically approved in 1954, along with three other metro lines and the Common Tunnel. Construction started in 1956 and was part of a process to transform Groruddalen into a residential area. The first part of the Grorud Line, from Tøyen to Grorud, was opened on 16 October 1966. The rest of the line opened in three stages: to Rommen on 3 March 1974, to Stovner on 18 August and to Vestli on 21 December 1975. The Ring Line connection opened on 22 August 2006 and since 2013 the Løren Line has been under construction.
Grorud is a district of the city of Oslo, Norway. The district contains the Ammerud, Grorud, Kalbakken, Rødtvet, Nordtvet and Romsås areas. To the north of the district is the forest of Lillomarka. The district is the smallest in Oslo, with less than 30 000 inhabitants.
The area now known as the district of Grorud was mostly farm land until after WWII, with an exception being Grorud proper, where mining was an important livelihood. The granite from Grorud is seen in all kinds of buildings in downtown Oslo - with the lion sculptures in front of Stortinget, the Norwegian Parliament being the most famous example. Textile industries were also a part of the urbanization of Grorud, with the river Alna and its waterfalls as power supply.
The railway station at Grorud is one of the oldest in Norway, and opened in 1854, and was a hub of the whole Grorud valley for many years until the arrival of urbanization and the subway. Some of the old farms are still present in the Grorud landscape, although apartment buildings now are a more dominant part of the scenery.
Grorud is a rapid transit station on the Oslo Metro. Located between Ammerud and Romsås on Grorud Line, it serves the Grorud borough. The station is located on the south side of a tunnel entrance. Above the station is a small cluster of shops and a small bus terminal.
The station was the end station of the original section of the Grorud Line, which opened 16 October 1966, and remained the end station until it was extended to Rommen on 3 March 1974.
