The Oslo Metro (Norwegian: Oslo T-bane or Oslo Tunnelbane or simply T-banen) is the rapid transit system of Oslo, Norway, operated by Sporveien T-banen on contract from the transit authority Ruter. The network consists of six lines that all run through the city centre, with a total length of 85 kilometres (53 mi),^[2] serving 100 stations of which 16 are underground or indoors. In addition to serving 14 out of the 15 boroughs of Oslo (all except St. Hanshaugen), two lines run to Bærum. In 2014, the system had an annual ridership of 88 million.^[1]

The first rapid transit line, the Holmenkoll Line, opened in 1898, with the branch Røa Line opening in 1912. It became the first Nordic underground railway in 1928 when the underground line to Nationaltheatret was opened. The Sognsvann Line opened in 1934 and the Kolsås Line in 1942. The opening of the upgraded T-bane system on the east side of town occurred in 1966, after the conversion of the 1957 Østensjø Line, followed by the new Lambertseter Line, the Grorud Line and the Furuset Line; in 1993 trains ran under the city between the two networks in the Common Tunnel, followed by the 2006 opening of the Ring Line. All the trains are operated with MX3000 stock. These replaced the older T1000 stock between 2006 and 2010.

History

Holmenkoll Line tram at Nationaltheatret in 1928

Suburban lines in the west

Rail transport in Oslo started in 1854, with the opening of Hoved Line to Eidsvoll, through Groruddalen. In 1872, Drammen Line, going through Oslo West, and in 1879, Østfold Line going through Nordstrand opened, offering a limited rail service to those parts of the city.^[3] By 1875, Kristiania Sporveisselskab (KSS) opened the first horsecar trams.^[4] In 1894 electric trams were in service by Kristiania Elektriske Sporvei (KES).^[5]

The first suburban tram line was the Holmenkoll Line that was opened by Holmenkolbanen in 1898; like all the later suburban tram line these were electric trams with a grade-separated right-of-way and proper stations instead of tram stops, making it the first rapid transit in Oslo. Unlike the other suburban tram lines that were built later, the Holmenkollen Line was not extended into the city as a streetcar—instead passengers had to change at Majorstuen to the streetcars, though the system did not take into use wider suburban stock (3.1 metres (10 ft)) until 1909.^[6] A branch line was opened in 1912, to Smestad,^[7] and in 1916 the Holmenkollen Line was extended to Tryvann, with the last part from Frognerseteren single track and used for freight,^[8] and removed in 1939.^[9]

T2000 stock at Majorstuen

In 1912, the construction of the first underground railway in the Nordic Countries started, when A/S Holmenkolbanen started construction of an extension of their line from Majorstuen to Nationaltheatret; the 2.0 kilometres (1.2 mi) line was opened in 1928, with one intermediate station at Valkyrie Plass, giving the two suburban lines access to the central business district of Oslo.^[10]

The success of the suburban lines tempted KES to extend their streetcar service west from Skøyen as a suburban line; the Lilleaker Line opened to Lilleaker in 1919, to Avløs in 1924 and to Kolsås in 1930. A new section from Jar to Sørbyhaugen opened in 1942, connecting the line from Jar to Kolsås to Nationaltheatret, and making it a rapid transit and the replacement of stock with wide suburban standard.^[11][12] This service remained part of the municipal Oslo Sporveier, that had bough all the streetcar companies in 1924.^[13]

Compensation for large amounts of damage to houses along the route during construction, along with higher construction costs than calculated was a heavy burden on the company, and in 1934, the municipality of Aker took over the common stock, though the preferred stock remained listed on the Oslo Stock Exchange until 1975, as Oslo Sporveier gradually took over the operation of the western suburban lines. Akersbanerne opened the connecting Sognsvann Line in 1934.^[10]

The first idea to launch a city-wide rapid transit was launched in 1912 with the construction of the Ekeberg Line; constructed with the same width profile as the Holmenkollen Line, the plan was to build a tunnel under the city center and run through trains, but large cost expenditures on the first section of the Common Tunnel ceased the plans. As part of the rebuilding after World War II a planning office for a T-bane was established in 1949, with the first plans launched in 1951; in 1954, the city council decided to build the T-bane network in Eastern Oslo with four branches. The system would feature improvements over the suburban lines in having a third rail power supply, cab signaling with Automatic Train Protection, stations long enough for six-car trains and level crossings replaced by bridges and underpasses—specifications christened metro standard.^[14]

At the time there were two suburban tramways on the east side, the Ekeberg Line (opened in 1919)^[5] and the Østensjø Line (1923).^[15] Only the latter would be connected to the T-bane; the Ekeberg Line would remain a tramway, but three new lines were to be built—the Grorud Line on the north side and the Furuset Line on the south side of Groruddalen and the Lambertseter Line on the east of Nordstrand. These areas were all chosen as new suburbs for Oslo, and would quickly need a good public transport system; suburban lines would first be built out extending from the existing tramway, and later a final section with tunnel to the central station would be built. The Lambertseter Line was opened in 1957, from Brynseng to Bergkrystallen while the Østensjø Line was extended to Bøler in 1958.^[14]

The metro opened on 22 May 1966, when the Common Tunnel opened from Brynseng to the new downtown station of Jernbanetorget, located beside the Oslo East Railway Station. In October the Grorud Line opened to Grorud while the Østensjø Line was connected to the system in 1967 when the line also was extended to Skullerud. In 1970, the Furuset Line opened to Haugerud and extended to Trosterud in 1974, at the same time as the Grorud Line was extended to Vestli. By 1981, the Furuset Line had reached Ellingsrudåsen.^[16] The metro took delivery of T1000 rolling stock from Strømmens Værksted; from 1964 to 1978, 162 cars in three-car configurations were delivered for the eastern network.

The Kolsås Line is being upgraded, and will lose the overhead wires

One tunnel

The eastern network was extended from Jernbanetorget to Sentrum in 1977, but Sentrum station had to close in 1983, due to water leakages. When it opened again in 1987, the west network tunnel had also been extended to the station, that opened as Stortinget. Through services were not possible at the time because of incompatible signaling- and power equipment. Not until 1993 did the first trains run through the station, after the Sognsvann Line had been rebuilt to "metro standard"; the Røa Line followed in 1995.^[17] The Holmenkoll Line and Kolsås Line remained without this standard, using dual mode trains that switch to overhead lines at Frøen and Montebello.^[18] The western network took delivery of 33 T1300 cars in 1978–81, with an additional 16 converted from T1000. In 1994 twelve T2000 cars were delivered for the Holmenkollen Line.^[19]

In 2003, the Ring Line opened from Ullevål stadion to Storo.^[12] The following year construction caused a tunnel to collapse on the Grorud Line—the system's busiest—forcing a shutdown of this line until December and creating a havoc of overfilled replacement buses.^[20] The ring was completed in 2006 onwards to Carl Berners plass.^[12] At the same time the Kolsås Line was closed for upgrade to metro standard.^[12] In 2003, the section of the Kolsås Line in Bærum closed due to budget disagreements between the two counties; after a year of unpopular replacement buses, the line was reopened, only to be closed again in 2006 for upgrade to metro standard. Disagreements between the two counties means the upgrade will be done separately on the two sides of the municipal boundary, with the Oslo side opening first.^[21] In 2006, the system started taking delivery of the new MX3000 units that replaced the old stock.^[22] The history of the metro and public transport in Oslo has been preserved at the Oslo Tramway Museum located at Majorstuen.^[23]

Network

The current route network was introduced on 9 December 2012, replacing the previous route numbering system introduced in the mid-1990s.

Schematic map of the metro (as of December 2012)

The Oslo Metro operates in all fifteen boroughs of Oslo, as well as reaching a bit inside the neighbouring municipality of Bærum. There are six lines, numbered 1 through 6, each color-coded. They all pass through the Common Tunnel, serving eight branch lines. In addition three lines operate to the Ring Line. The only branch to have two lines is the Furuset Line, served by both lines 1 and 2.^[24]

The Grorud and Furuset Line head northeast into Groruddalen, while the other two eastern branches head south into Nordstrand. On the west side, the Holmenkoll and Sognsvann Line cover the northern boroughs of Oslo, along with the Ring Line that connects the northeastern and northwestern parts of town. The Kolsås and Røa Line reach deep into the neighbouring municipality of Bærum.^[12] All the lines run through the Common Tunnel before reaching out to different lines, or into the Ring. Each line runs every 15 minutes, 30 minutes in the late evening and in the morning at weekends. In addition, line 5 has supplemental trains on weekdays except during vacation seasons giving a total of eight trains an hour on that line. Trains run from about 0500 (0600 at weekends) to 0100 the next morning.^[24]

Stations

Nydalen on the Ring Line opened in 2003.

The system consists of 97 stations, of which 16 are underground or indoors.^{[25][26][27][28]} The only underground station on the pre-metro western network was Nationaltheatret, and most of the underground station are in the common tunnel under the city center, or in shorter tunnel sections on the eastern network; in particular the Furuset Line runs mainly underground, with all but Haugerud built in or at the opening of a tunnel.^[29]

Stations in the city center are located close to large employment centers as well as connection possibilities to other modes of transport, such as tram, rail and bus. All stations can be identified at ground level by signs with a blue T in a circle. Stations outside the center are unmanned since the 1995, with ticket machines for fare purchase;^[12] some stations feature kiosks. A system of turnstiles have been installed, but will never be activated due to security issues. All stations have step-free accessibility through at least one entrance (except the inbound platform at Frøen), and the platform height is aligned with the train cars.^[30]

Intermodality

Blindern on the Ring and Sognsvann Line serves the main campus of the University of Oslo.

The metro is integrated into the public transport system of Oslo and Akershus through the agency Ruter, allowing tickets to also be valid on the Oslo Tramway, city buses, ferries, and the Oslo Commuter Rail operated by Norwegian State Railways.^[31] A new, wireless ticketing system, Reisekort, has in the recent years been implemented.^[32] From 1 February 2014 a single ticket for one zone (the entire metro system is in zone 1) cost NOK 30, monthly passes NOK 650.^[33] This includes all means of public transport within the zone you've got a ticket for (for the metro, zone 1).There is a fine of NOK 750, or NOK 900, for not having a valid ticket, depending on whether or not you pay the fee on location.^[34]

Oslo maintains a street tram system with six lines, of which two are suburban lines.^[35] The street trams operate mostly within the borders of the Ring Line, providing a frequent service in the city center, with lower average speeds but with more stops. There are major transfer points to the tramway at Majorstuen, Jernbanetorget, Jar, Storo and Forskningsparken.^[36][37]

The commuter train serves suburbs further away from Oslo, though some of the commuter rail services remind of a rapid transit service, in particular line 400 and line 500, to Lillestrøm, Asker and Ski, with higher service frequency through the continual populated area of Oslo. Transfer to railway services is available at Jernbanetorget (to Oslo S) and Nationaltheatret, the latter with a considerably shorter walk.^[38]

Bus services are provided to numerous stations. Most bus services provide feeding to the metro system where possible, and then do not continue into town. However, since the metro operates solely into town, instead of across it, many buses operate between stations on different lines, or provide alternative routes across town.^[39]

Future expansion

The proposed T-bane structure after Oslopakke 3

• Between 2006 and 2014 the Kolsås Line was upgraded to metro standard.^[40]
• As part of the political compromise Oslo Package 3 a number of changes have been proposed for the Oslo Metro.^[41]
  • Expansion of the Furuset Line to Lørenskog with stations at Skårer, Lørenskog Centre and a new terminus at Akershus University Hospital, with travel time to Jernbanetorget of 27 minutes.
  • The frequency on the eastern lines will be increased. Grorudbanen, Lambertseterbanen, Østensjøbanen and Furusetbanen will get eight departures per hour, with half (B-routes) terminating at Majorstuen for Lambertseterbanen and Furusetbanen. This will reduce the capacity in the Common Tunnel.
  • The construction of the Løren Line will connect the Ring Line with the Grorud Line, allowing trains to run from Grorudbanen directly to the Ring. In addition a new station at Løren would be built. This will not increase the load on the Common Tunnel since it is an extension of the current line that terminates at Storo, and will also make way for eight departures per hour on the Østensjø line. This will also give all stations except Hasle and Løren eight departures per hour.
  • A new station, Homansbyen, on the Common Tunnel between Majorstuen and National Theatre.
• Although not part of Oslo Package 3, the Fornebu Line, which has been variously proposed as a light rail, metro and an automated train line since 1997, is planned to run from Majorstuen to the old airport area at Fornebu.

Rolling stock

MX3000 stock on the Røa Line

The trains on the Oslo metro are currently exclusively the MX3000, ordered in 2003 to replace the oldest T1000 stock. Delivery started in 2006, and unlike older stock the MX3000 units are painted white instead of red. 83 three-car units were ordered in 2006;^[22] a further 32 were ordered in December 2010.^[42]

A number of versions of the T1000 stock have earlier been used on the Oslo metro. This includes 146 cars of the types T1 through T4, that have third-rail only operation, and thus did not run on the Holmenkollen and Kolsås lines. These ran usually in units of three or six (sometimes four or five) cars. Types T5 to T8, 49 in total, delivered with both third-rail and overhead wire equipment, normally ran on the Holmenkollen line (two cars) and Kolsås line (three cars).^[19]

When the Holmenkollen Line was connected to the T-bane it was still using old teak cars; to allow through services the T2000, capable of dual-system running, was delivered in 1993. They were not particularly successful and only 12 units were delivered, operating in pairs on the Holmenkollen line sometimes connecting with the Lambertseter line, and scrapped in 2010.^[43]

Depots and facilities

• Avløs Depot – located near Avløs station on the Kolsås Line, it has been closed for refurbishment since 2011 and is expected to reopen in May 2015.^[44]
• Etterstad Depot – located on the shared section of the Østensjø Line, Furuset Line and the Lambertseter Line before Brynseng station, it is used as the main operations centre for the Oslo Metro and has a yard for maintenance of way equipment.
• Majorstuen Depot – a small yard used mainly for storing trains, located just beside the Oslo Tramway Museum.
• Ryen Depot – the main storage and maintenance yard for all Oslo Metro trains, located on the Lambertseter Line near Ryen station.
