 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 ( 1886 – 1977 ) . 
 The line was originally double @-@ tracked from Majorstuen to Korsvoll ( now Østhorn ) 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 newspaper Aftenposten 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 .
