History
Since the opening of the Oslo tram network in 1875, there was a tram stop at the station site, near the courthouse.
On May 22, 1969, the Oslo City Council decided to build a subway station in this place, as well as a transfer station near the Norwegian National Theater . In 1972, the construction of the station began, during which the first leaks were discovered that were not eliminated by the time the station was opened.
January 9, 1977 the station was opened under the name "Center" (Sentrum), providing communication with the eastern part of the subway. Since the start of the movement in January, it was found that the routes were laid too low: a normal exit to the platform (as well as an entrance from it) was not possible in any of the types of wagons used, and therefore it became necessary to shift the paths higher.
In 1978, it became clear that the leaks at the station were getting out of control, but only in February 1983 the station was closed to completely eliminate them, and it was assumed that the station could be reopened in 1984. The causes of leaks were both the use of an unacceptable concrete grade during the construction of the station, and the wrong method of its construction. In the construction contracts, everything was indicated correctly, but after choosing a contractor, an agreement was concluded between her and the municipality on the use of a different construction method, which, along with the poor quality of concrete, made leaks inevitable. To ensure the repair of the station in 1986, the municipality sued 158 million NOK from the contractor.
On March 7, 1987, the station, with a new name, was reopened, providing communication not only with the eastern, but also with the western part of the subway - by that time the creation of the General Tunnel was completed .
Until 1993, the station was final: two of its four platforms were used for trains arriving from the east, and the other two were used for trains arriving from the west.
