Construction of single dwellings in the area commenced in the 1920, starting off with the Blindern Haveby estate. In 1920 the
Parliament of Norway decided that the area would be the main campus for the
University of Oslo. Meanwhile,
Aker Municipality worked with plans for construction of a suburban railway which would serve the areas around Blindern.
Holmenkolbanen was granted permission in 1922, but the plans were placed on hold. Work commenced again in 1933 and the line opened on 10 October 1934. It was originally called Blindernveien. The
Norwegian Meteorological Institute moved to Blindern in 1937, but large-scale development of the campus did not take place until the 1960s. The upgrade also involved standardizing the design on all the stations on the Sognsvann Line. The station cut off the road Blindernveien, as it could not longer cross the tracks. Originally the plans had called for the street to be carried over the station on an overpass. This was protested by local residents, and eventually led to a much smaller overpass being built which only carried a combined pedestrian and bicycle path. From 8 April 1995 the trains from the
Grorud Line terminated at Blindern. From 20 August 2003 the new
Ring Line opened and Line 5 continued through it. The university was working for renovation of the station for its bicentennial anniversary in 2011, but this was never carried out due to lack of funding. The project would have seen new platforms and a new overpass with separate bicycle and pedestrian pathways. ==Service==
