The Kolsås Line ((ノルウェー語:Kolsåsbanen)) is line of the Oslo Metro. It branches off from the Røa Line at Smestad Station and runs through western Oslo and Bærum to Kolsås Station. It serves the neighborhoods of Ullernåsen, Øraker, Jar, Bekkestua, Haslum, Gjettum and Kolsås. It is served by Line 2 of the metro at a 15-minute headway. The section from Jar to Bekkestua is build as a dual system with overhead wires, allowing Line 13 of the Oslo Tramway to continue from the Lilleaker Line to Bekkestua every ten minutes. The Kolsås Line was built as an extension of the Lilleaker Line. It had been built to Lilleaker in 1919. The line was extended to Avløs on 1 July 1924, and the line was extended to Kolsås on 1 January 1930. The line was initially owned by Bærumsbanen, which was bought by Oslo Sporveier in 1934. A connection to the Røa Line opened on 15 June 1942, allowing the line access to the Common Tunnel. At this point the section from Sørbyhaugen to Kolsås was designated the Kolsås Line, while the section from Jar to Skøyen was retained as the Lilleaker Line. T1300 trains of the metro were introduced in 1982 and from 19995 it was linked with the eastern metro lines. The line closed for upgrades to metro standard in 2006. It reopened in eight stages from 2008 to 2014. There are plans to extend the line to Rykkinn, Bærums Verk and Sandvika, although none of these have political priority.〔 ==Route== The Kolsås Line branches off from the Røa Line after Smestad Station at a site previously occupied by the now closed Sørbyhaugen Station.〔 Sørbyhaugen is situated from Stortinget at an elevation of . Previously there was a station at Husebybakken. The line runs parallel to Ring 3, through four stations in Oslo: Montebello, Ullernåsen, Åsjordet and Bjørnsletta.〔 Situated at elevation, Ullernåsen is the highest elevated station on the line.〔 The line largely runs along Bærumsveien from slightly before Bjørnsletta.〔 At Øraker the Lilleaker Line meets the Kolsås Line, after which point the lines share tracks.〔 The line crosses the municipal border across the river Lysakerelven. The now closed station of Lysakerelven, from Stortinget, was situated on the Bærum side of the municipal border between Oslo and Bærum.〔 At Jar there are two sets of platforms, one for the metro and one for the trams. The continues past Ringstabekk, which is only served by the metro. It replaced three disused stations, Tjernsrud, Ringstabek and Egne hjem.〔 Situated from Stortinget,〔 Bekkestua is the terminal station for the tramway, and a major transit hub for central Bærum. Like Jar, it features two sets of different platforms. The shared rail section features both third-rail power supply and overhead wires. The trams have a narrower loading gauge and shorter platforms, making it necessary to provide separate platforms for them.〔 The line continues past Gjønnes and Haslum to Avløs, which is one of the three Oslo Metro depots. After that point, it passes through the stations of Valler to Gjettum and Hauger before reaching the terminus, Kolsås Station, which, situated from Stortinget, is the terminus of line 2 and the station furthest away from the centre of Oslo.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kolsås Line」の詳細全文を読む スポンサード リンク
