Grorudbanen
Encyclopedia
The Grorud Line is a 13 kilometres (8.1 mi) 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.
and Grorud
. From Carl Berners plass to Ensjø
, there is a single-tracked branch, which allows trains access to the other eastern lines without having to change direction.
The rapid transit station is served by lines 4, 5 and 6 of the Oslo Metro. Line 5 has eight services per hour, while the other two operate four times per hour. All have reduced services during late evenings and parts of the weekends. Line 5 runs the entire section of the Grorud Line, while lines 4 and 6 both only run from Tøyen to Carl Berners plass, and then run along the Ring Line. Line 6 only runs towards the city center, while Line 4 only runs from the city center. Operations of the line is done by Oslo T-banedrift on contract with Ruter, the public transport authority in Oslo and Akershus
. The infrastructure itself is owned by Kollektivtransportproduksjon, a municipal company. Service is provided using MX3000 three- and six-car trains. The line has 40,000 daily passengers, making it the busiest branch of the metro. Travel time along the line, from Tøyen to Vestli, is 23 minutes. Travel time from Vestli to Stortinget
in the city center is 27 minutes. Transfer to Ruter buses are available at Tøyen, Carl Berners plass, Hasle, Økern, Linderud, Ammerud, Grorud and Stovner. Transfer to the Sinsen Line
of the Oslo Tramway is available at Carl Berners plass.
were merged, and the new municipality started planning an expansion of the suburbs, among other places in Groruddalen. On 15 September 1949, the Planning Office For the Suburban and Underground Lines was establish as a division within the new municipality. The first specific plans were launched in March 1954, and consisted of four branches, including one on the north side of Groruddalen, which would be built to Grorud. The plans originally consisted of terminus in the city center at Grønlands torg
, with a possible extension to Nationaltheatret, where the line would intersect with Holmenkolbanen
's light rails serving Oslo West. However, it was quickly decided that the terminus would be Jernbanetorget, which served the Oslo East Station.
Construction of the Grorud Line started in February 1956. Landwork and electrical equipment was contracted to developers, while the trackage was done by the Planning Office. The original plans called for the use of 600 to 650 volt
(V) direct current
(DC) fed via a pantograph
, to allow comparability with the western light rail. This was later changed to 750 V DC via a third rail
. This was chosen to allow a higher diameter, and thus a higher ampere
, and easier maintenance. The system also took into use cab signaling and moving block
s, which were cutting edge technology at the time, and had only been implemented on the Stockholm Metro
in Europe by then. While the permitted headway
on the common sections was set to 90 seconds, it was set to 120 seconds on the Grorud Line. The original plans called for a depot on each of the lines, including the Grorud Line, but this was later changed to a central depot at Ryen
.
The section from Tøyen to Grorud was opened on 16 November 1966, five months after the metro had opened with the Lambertseter Line, and as the first branch of the metro to not be converted from a light rail. The Grorud Line was extended on 3 March 1974 to Rommen, on 18 August to Stovner, and was completed on 12 December 1975 to Vestli. The line took into use T1000 electric multiple unit
s which could be up to six cars long. Originally the service terminated at Jernbanetorget in the city center, in addition to a service which ran via the branch from Carl Berners plass to the Lambertseter Line, and terminated at Ryen
. On 9 January 1977, the city center service was extended to Sentrum. However, this station was closed from 20 March 1983 to 7 March 1987, and reopened as Stortinget. From 8 April 1995, the trains on the Grorud Line continued all the way through the Common Tunnel to Blindern
on the Sognsvann Line, which serves the main campus of the University of Oslo
.
On 20 August 2003, Line 5 had its western terminus extended to Storo, which opened along with the first part of the Ring Line. In on 17 July 2004, during construction of the Ring Line, part of the tunnel collapsed, causing the Grorud Line to be closed for six months, causin the 40,000 daily riders to have to use a bus from Tøyen. On 22 August 2006, the Ring Line was opened from Carl Berners plass to Sinsen
, resulting in the section from Tøyen to Carl Berners plass also being served by lines 4 and 6. In 2007, the system started taking delivery of the new MX3000
units which would replace the old stock. From 18 August 2008, the line's frequency was increased from four to eight trains per hour, although the extra trains terminate at Stortinget. By 2010, all T1000 stock had been retired.
and Økern. Trains running on the line will connect to the Ring Line via the Hasle Line. Other proposals involve extending the line to Slattum in Nittedal.
In the western end of the Grorudalen, a branch from Stovner has been proposed to connect to the Furuset Line. It would have new stations at Øvre Stovner, Lørenskog Station
of the Trunk Line and the Oslo Commuter Rail
, and Visperud
. Visperud has also been proposed as a location for a park and ride
for between 500 and 2,000 cars, as it is located on National Road 159
and European Route E6
. Part of the rationale is to serve the new suburb of Skårerødgården, which is planned with 1,200 new houses, located within the catchment area of Lørenskog Station. The line would run entirely underground. The cost of building the 4.8 kilometres (3 mi) from Ellingsrudåsen to Stovner is estimated at NOK 2.4 billion.
Independent of the northern extension, is a branch from the Furuset Line to a point on the Grorud Line. The plan is to build a new line from Økern via Breivoll, where there would be an interchange with the Trunk Line, to Trosterud
on the Furuset Line. Such a cross connection will allow both interconnection between the lower levels of the Grorud Line and the Furuset Line, and at the same time give access from the Furuset Line to the Ring Line. In addition to this, the plans call for a parallel line to the Furuset Line to run through the lower parts of Grurudalen, between the Furuset Line and the Trunk Line. This line could either connect to the Furuset Line at Furuset, or run across the valley, via Grorud Station
on the Trunk Line, and connect to the Grorud Line at Rommen.

It is proposed built between Hasle and Økern, and would allow trains to serve Sinsen and onwards on the Ring Line. The proposal is part of Oslo Package 3 and is budgeted to cost NOK 600 million. It would include a station at Løren, which is estimated to have 6,000 daily passengers.
