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. Since 2003 the Ring Line has branch off from the Sognsvann Line north of Ullevål stadion.

History
The Ullevål area had residential development from 1855. However, first in the 1920s was there a large-scale construction. Ullevål Hageby was served by the Ullevål Hageby Line of the Oslo Tramway from 1925. Ullevaal Stadion opened the following year, but initially lacked any proper public transport. Aker Municipality worked with plans for construction of a suburban railway which would serve the area. Holmenkolbanen was granted permission in 1922 to build a line, but the plans were placed on hold. Work commenced again in 1933 and the line opened on 10 October 1934.

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. From 20 August 2003 the new Ring Line opened and Line 5 continued through it.

Service
The station is served by lines 4 and 5 of the Oslo Metro. During regular hours, each operates at a 15-minute headway. Line 5 passes twice through the Ring, so that there are services every five minutes to the city center and twice every fifteen minutes to the Ring Line. Travel time to Stortinget is nine minutes. Operations are carried out by Sporveien T-banen on contract with Ruter, the public transport authority in Oslo and Akershus. The infrastructure itself is owned by Sporveien, a municipal company. Service is provided using MX3000 three- and six-car trains. The station had an average 2,009 boarding passengers in 2002, ranking ninth among the metro stations that year. It is located in fare zone 1.
