'Kolsåsbanen' is a subway line on the
Oslo T-bane network which runs between downtown Oslo and
Kolsås. With 18 km, it is one of the longest lines of the entire network. A long stretch of the line is located in
Bærum. From
August 20 2006 the line connects with
T-baneringen and has line number 6 (the trains continue through the loop and leave on the east side on
Lambertseterbanen changing to number 4 during the journey). At present most of the line is closed for upgrading. However, the stretch between
Jar and
Bekkestua is temporarily served by
the Oslo tram line 13
[1].
Originally, Kolsåsbanen was built as an extension of the tram line
Lilleakerbanen. It was completed to Kolsås in
1930. In 1942 the stretch between Sørbyhaugen (now a closed station on
Røabanen) and
Jar was completed, and Kolsåsbanen became part of the network operated by
Holmenkollbanen AS. Jar station is now a rare instance of a tram line sharing track with a subway line.
On
July 1,
2003 budgetary disagreements between local politicians in Oslo, Bærum and Akershus led to the closure of the
Bekkestua to Kolsås leg. It was temporarily reopened
November 22,
2004 but the future status is unclear. Possible options have been upgrading the line to metro standard as was done with
Sognsvannsbanen and
Røabanen, or cutting the line to Jar, and have the
tram run the stretch between Jar and Kolsås.
Early 2006, Akershus County Council gave the green light for a NOK 750m upgrade of the line. The detailed plans are still to be finalised but the intention is to upgrade the line to full "metro" standard all the way to Kolsås with a six-car train service in operation. Additionally, a light rail service will share the tracks between Jar and Bekkestua. The intention is to create a transport hub at Bekkestua enabling interchange with local bus services.
Most of the line was closed down on
July 1 2006 due to upgrades, which are expected to be completed to
Åsjordet by the end of 2007. From
July 31 there is only one operational station unique to Kolsåsbanen,
Husebybakken, which has temporarily replaced
Montebello [1].
Up to 2006, the line was operated with
overhead wire from
Montebello outwards, with fairly short platforms only accommodating three-car trains. The line has a few
level crossings.
