Berg station was opened on 10 October 1934, when the municipally owned company Akersbanerne had completed the Sognsvann Line from Majorstuen to Sognsvann. Residential areas at Sogn, Tåsen and Berg were starting to grow, in pace with a larger suburban development plan. Akersbanerne bought new property along the line, upon which new houses were to be designed by the Norwegian architect Kristofer Lange. The line was originally double-tracked from Majorstuen to Korsvoll station and single-tracked from Korsvoll to Sognsvann. On 21 February 1939, the section from Korsvoll to Sognsvann was upgraded to double tracks, and Korsvoll station had its name changed to Østhorn. In the 1980s, the stations on the Sognsvann Line were rebuilt. The platforms were lengthened from fitting two-car to fitting four-car trains and the platform height was increased. The third rail made it impossible to cross the line at-grade; an underpass was therefore constructed at Berg station. The station was also redesigned in concrete with steel columns and wooden sheds designed by architect Arne Henriksen. In 1991, Oslo Sporveier presented plans involving a rapid transit circle line in Oslo, connecting the newly built hospital Rikshospitalet with the rest of the city. A detailed suggestion was presented by Oslo Sporveier in August 1996. In the local newspaperAftenposten Aften there was a debate on whether there should be a ring line from Berg along the National Road 150 towards Gaustad over Rikshospitalet, or whether the Ullevål Hageby Line should be extended from John Colletts plass to Rikshospitalet, thereby creating a correspondence with the Sognsvann Line at the new station Forskningsparken. In the first plans, Berg was meant to be a station on the new ring line. This plan was discarded since local residents feared noise pollution and destroyed lawns. Even though Berg was not made a station on the Ring Line, noise shields were put up along the Sognsvann Line. Berg station has seen many accidents and almost-accidents. In 1965, a deadly accident occurred between Ullevål and Berg stations, when a train ran over a 33-year-old man walking in the tracks. In 2002, a 24-year-old man was run over by a metro train approaching the station. The man survived the accident with minor wounds. In 2008, a 21-year-old drunk man was found crawling around on the tracks between the platforms. The police removed him from the station and sent him home in a taxi.
