Located at Helsfyr in Oslo, Norway, the area has a mixture of apartment buildings and small businesses.

From 2 January 1955, the Rodeløkka Line of the tramway was rerouted to run via Carl Berners plass, although it was closed again on 1961.

The underground metro station opened on 16 October 1966, and the trolleybus service was replaced by diesel buses in 1968.

The underground metro station is on the Grorud Line, and is located 3.3 kilometers (2.1 mi) from Stortinget in the city center.

From 19 December 1939, the line was extended along Trondheimsveien to Sinsen; this section was built with double track.

In 1948, the tracks at Carl Berners plass was rebuilt to run through the roundabouts at both ends of the square.

[7] The metro station at Carl Berners plass was opened along with the Grorud Line on 16 October 1966.

[7] The Sinsen Line was among those proposed for closure in 2002 when the tram company attempted to save money by transferring the traffic to buses.

[9] The metro station was for many years in bad need of rehabilitation, with dim lighting at the platforms, grimy walls, and broken roof tiles leaving piping and wiring exposed.

Architect Reiulf Ramstad, who was in charge of the renewal project, compared the station to the scenery of a horror movie.

[11][12] From 20 August 2006, Carl Berners plass also started serving the Ring Line of the metro.
