The station opened on 10 October 1934 at the same times as the rest of the Sognsvann Line. The station received a major upgrade in 1993, in which it received longer platforms and an overpass. The new station was designed by Arne Henriksen. Among the most used stations west of the city center, it derives its high ridership from two student dormitory complexes.

History
Construction of the Sognsvann Line started in 1933. It and Kringsjå Station were opened on 10 October 1934. At first the line was built with double track to Østhorn and single track to Sognsvann. Between 1937 and 1939, the upper section was converted to double track. Unlike further south along the line there was not as much construction of housing. The area around Kringsjå was mostly developed from the 1960s. Until 1970 there was a café at the station. Kringsjå Student City opened in 1970, followed by Fjellbirkeland Student City in 1990. East of the station there was also a major construction of condominiums and row housing since the 1960s.

During the 1980s, the city decided to connect the four suburban lines west of the city center with the Oslo Metro. The Sognsvann Line was selected as the first line to be upgraded, so the two systems would become compatible. The line was upgraded to metro standard by replacing the overhead wire with a third-rail power supply and installing automatic train protection. From 4 April 1993 trains along the Sognsvann Line were connected to the eastern part of the metro, initially connected with the Østensjø Line.
