Grorud Line - Future

Future

The Hasle Line is a proposed branch which would connect the Grorud to the Ring Line in such a way that trains running down the Grorud Line can turn onto the Ring Line. 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. The branch will increase the number of east–west trains on the metro, without having to upgrade the Common Tunnel. Ruter has also proposed building a connection with the Furuset Line, between Furuset 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 kilometers (3.0 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.
