context_page_description: The Holmenkollen Line is an 11.4-kilometre-long Oslo Metro line which runs between Majorstuen and Nordmarka in Oslo, Norway. Operating as Metro Line 1, it is the route with the fewest passengers and the only one still to have level crossings and short station platforms. The line runs mostly through residential areas of detached houses, and the upper parts of the line principally serve the recreational area of Nordmarka. Holmenkollen Station is located close to Holmenkollen National Arena which hosts international Nordic skiing tournaments.
  The line is the oldest one on the metro system, having been opened as a light railway in 1898 by the Holmenkolbanen company. Originally it ran for 6.2 km from Majorstuen Station to Besserud. In 1916, the line was extended to Tryvann, with the last 1.4 km being used for freight only. In 1928, the city terminus was moved 2.0 km to the underground Nationaltheatret Station.
context_section_description: The line was opened on 31 May 1898 as a tram line between Majorstuen and Besserud. The line was extended to Frognerseteren on 16 May 1916, and the tunnel between Majorstuen and Nationaltheatret, now part of the shared downtown subway stretch, was opened 6 June 1928, which was the first subway line in Scandinavia.
  On 22 October 1987, the line suffered a fatal accident when a braking system failed in a train causing it to roll down the line, finally tipping over at Midtstuen. The accident killed one person and seriously injured four others. The accident led to scrutiny of the safety of the old teak cars which were used on the line. The old trains were pulled from service, but reintroduced after some refits of the cars until new trains were delivered in 1993.
  Until 1991, A/S Holmenkolbanen was the company responsible for the operations of the line, but the company was then merged with Oslo Sporveier. In a cost-saving measure between 2002 and 2004, the line was taken off the downtown shared stretch and ran only between Majorstuen and Frognerseteren.
