What is "sinsen"

Sinsen is a mixed residential and commercial area in Grünerløkka borough of Oslo, Norway. The westernmost part of Sinsen is part of the borough Nordre Aker.

The Sinsen Interchange, located on the border between the boroughs of Nordre Aker, Grünerløkka and Bjerke, was the first roundabout in Norway. It has since developed into a multi-lever intersection, with both Ring 3, National Road 4 and the Sinsen Line of the Oslo Tramway routes around. "North of the Sinsen Interchange" is common expression in the Norwegian district debates, where inhabitants of Oslo are accused of being ignorant of the country north of the interchange. The expression cropped up in revues during the 1960s, and is probably due to that Sinsen then was the end point for the main road leading into Oslo from the north.

The area is served by the Sinsen Line of the Oslo Tramway. The Oslo T-bane serves the neighborhood at Sinsen Station, while the Gjøvik Line serves the area at Grefsen Station.

Sinsen is a rapid transit station on the Ring Line of the Oslo Metro. It is located at Sinsen in the Sagene borough of Oslo, Norway.

The station opened on 20 August 2006, as part of the first section of the Ring Line. The station is served by line 6 of the metro, as well as several local bus services. Sinsen is a mixed residential and commercial area.
