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: Oslo Sporveier was highly satisfied with the SL79 articulated trams that had been delivered during the 1980s for the tramway. In 1985, work started on the development of a modified version for the western suburban lines. The stock on the Holmenkollen and Kolsås Lines were the first that needed to be replaced. The new stock was considered to be a limited trial. If it met performance expectations, future orders could be made to replace the T1000 stock when the latter reached the end of its economical life in around 2000. The required specification for the new train was published in October 1988. On 22 October 1987, a fatal accident occurred when one of the old HkB 600 units suffered a catastrophic failure of its braking system, and rolled down the Holmenkollen Line, finally tipping over at Midtstuen. One person was killed and four were seriously injured, leading to a safety inspection of the old teak cars used on the line; the HkB 600 units were withdrawn from service, but were reintroduced after some refits.
  The initial proposal had called for 22 units, to replace all of the Kolsås and Holmenkollen Line stock. However, the Sognsvann and Røa Line was upgraded to metro standard between 1992 and 1995, and could start using T1000 stock with only third-rail support. At the time, the eastern network used third-rail, while the western network used overhead wire. The upgrade used non-utilized stock, so the order for T2000 was reduced to 12 units. The order was placed with ABB Strømmen and AEG in August 1991. The high development cost was subsidised by the Norwegian government, who saw the project as potentially establishing a new industrial export product. Electrical components were built by AEG in Berlin, while the bogies were built by MAN in Nuremberg. The bodywork was built at Strømmen, with profiles from Alusuisse, and the trains were assembled in Strømmen. The six two-car sets were delivered between 2 November and 22 December 1994. The first official public presentation was made on 8 December, but the units did not enter regular service until April 1995. The cars were numbered 2001–2012. The T2000 class was prone to technical problems, and was not as reliable as the older T1000 stock. It soon became evident that no more would be ordered.
