Flytoget () is an airport railway service connecting Oslo Airport to Oslo Central Station. Run by Flytoget AS (formerly NSB Gardermobanen AS), it operates on the Gardermoen Line using sixteen GMB Class 71 electric trains. Normal service frequency is once every ten minutes, with five of the services each hour continuing westwards beyond Oslo Central. The journey takes nineteen minutes, with extended services serving nine stops within Greater Oslo and taking up to 60 minutes.
Flytoget transported 5.4 million passengers in 2007, a 34-percent market share of airport ground transport. The service, which has a top speed of , is the only high-speed rail service in Norway. Construction started in 1994 and high-speed trains began serving Gardermoen Airport from the date of its opening on 8 October 1998, although full operation using the Romerike Tunnel had to wait another ten and a half months after severe leaks caused by the tunnel's construction led to the partial depletion of two lakes.
Formed in 1992 as a subsidiary of Norwegian State Railways, the company has been owned since 2001 by the Norwegian Ministry of Trade and Industry.
History
Decision for a new airport connection When the Parliament of Norway on 8 October 1992 decided to build a new central airport for Eastern Norway, they also decided that the main mode of ground transport should be by rail. While the previous airport, Oslo Airport, Fornebu, was located just outside the city limits, the new airport, Oslo Airport, Gardermoen, would be located north of the city, outside the reach of existing public transport. The principle of the airport construction was that it was not to be footed by the tax payers; the entire airport would be built with borrowed money through Oslo Lufthavn AS, a subsidiary of the Norwegian Airport Administration. The same principle was chosen for the airport rail link—the Norwegian State Railways (NSB) creating the limited company subsidiary NSB Gardermobanen AS, founded on 24 November 1992, to perform the construction of the line. It would be able to charge train operators using the line, channeling the payments to cover down payments and interest of the debt used to build the railway. Profit margin was estimated to 7.5%.
Construction
Oslo Airport, Gardermoen, is not on the Trunk Line that runs north from Oslo. With heavy traffic and many small stops until Lillestrøm, and continuing north as single track, the Trunk Line would have to be supplemented by a parallel double track from Oslo, with a new route north of Kløfta to Eidsvoll, the north of the airport allowing trains operating on the Dovre Line to Lillehammer and Trondheim to access the airport. The line was named the Gardermo Line.
The Gardermo Line was the second attempt to build high-speed rail in Norway, after the line from Ski to Moss on the Østfold Line. But no operation speeds exceeding are achieved there due to short distances and limitations to rolling stock, making Gardermobanen the first real high-speed railway line in Norway. Due to the domination of single track in Norway, the opening of the Gardermo Line increased the total length of double track in the kingdom by two-thirds.
Construction started in 1994. An agreement for purchase of sixteen three-car electric multiple units was signed with Adtranz on 23 February 1995. Parliament decided on 1 October 1996 that the construction company would also operate the new train service. The trains were delivered between 19 September 1997 and 30 January 1998, costing NOK 1.4 billion.
Challenges
The greatest challenge was the need to build the Romerike railway tunnel – Norway's longest – beneath the geologically highly unstable Østmarka area between Etterstad, close to Oslo Central Station, and Lillestrøm. During construction, in 1997, the water level in some lakes above the tunnel, including Lutvann and Nordre Puttjern, sank dramatically. After the leaks were discovered on 3 February 1997, sanctions were imposed by the Norwegian Water Resources and Energy Directorate requiring the elimination of all leakages. At its worst, the tunnel was leaking of water per minute.
Rhoca-Gil sealant was used in an attempt to fix the leaks, but failed to work properly. Not only did it not polymerise, and therefore failed to staunch the leaks, but it also poisoned its surroundings with acrylamide. Manual fixing with concrete became necessary; the fixing and cleaning up of the toxin delayed the building of the tunnel by one year. Further complications arose due to conflicts between NSB Gardermobanen and the construction company, Scandinavian Rock Group, with the latter at one instance stopping work for three weeks while the parties quarrelled in court.
Reports have shown a lack of inspection and reporting procedures during incidents that should have been addressed – but were never taken seriously – in 1995. Construction of the tunnel caused damage to around sixty houses and an evaluation by the Ministry of Transport and Communications showed that NOK 500 million was spent on fixing the leaks and claimed that this was to a large extent an unnecessary expenditure which more efficient engineering procedures would have avoided. The report also criticised the administrative planning and organisation of the overall construction of the railway.
Airport Express Trains began operating as soon as the new airport (and the Lillestrøm to Gardermoen stretch of the new high-speed line) opened on 8 October 1998; however, for more than ten months they had to use the old Hovedbane (Trunk Line) between Oslo S and Lillestrøm, which restricted their frequency to just two trains per hour. Regular operations at full capacity, using the Romerike Tunnel, did not commence until 22 August 1999.
Reorganisation
Estimates for the project costs were NOK 4.3 billion, ±20%, but by completion they had ended at NOK 7.7 billion, of which NOK 1.3 billion were related to the leakages. The rest of the line had a cost exceedings of NOK 0.4 billion. The company had acquired financial costs of NOK 0.9 billion, so the company owed NOK 10.0 billion by 1999, including money spent on the new trains.
The first steps of organisational restructure were taken 29 June 2000, when the CEO of NSB, Osmund Ueland, was fired due to several incidents related to the operations of NSB—not just the Gardermo Line. Einar Enger took over as new CEO on 26 February 2001.
The debt in NSB Gardermobanen had become unmanageable, and in April 2000 parliament accepted that it would not be possible to make the Gardermo Line—with the current structure—the profitable venture predicted in 1992. From 1 January 2001, the company changed name to Flytoget AS, retaining ownership of the trains and operations and kept as a subsidiary of NSB. The tracks and infrastructure were transferred to the Norwegian National Rail Administration (), who owns the rest of the Norwegian railway network. All debt was restored and covered by the state, and a vehicle excise duty was implemented on the Gardermo Line to cover the management and maintenance of the line, to be paid by all users.
On 9 December 2002, parliament decided that Flytoget AS would become a separate railway company from 1 January 2003, owned directly by the Ministry of Transport and Communications. One year later the ownership was transferred to the Ministry of Trade and Industry as part of a cleanup of political overhaul between the departments. As part of the process, a new CEO, Thomas Havnegjerde, was appointed in June 2002, and in January 2003 the new chair, Endre Skjørestad—who took over the position form NSB's director Einar Enger. Havnegjerde announced on 6 August 2008 that he would retire from his job before the end of the year. He was replaced by Linda Bernander Silseth on 10 November 2008. On 30 August 2009, two of three services to Asker were extended to Drammen. This followed upgrades to the Drammen Line, including the Lieråsen Tunnel, and a new parking lot at Drammen Station, in total costing NOK 20 million.
Discontinuation In February 2026, the Norwegian government announced that Flytoget services would cease in December 2027, the offer being integrated into the regional train network.
Operations
Departures operate every ten minutes from Oslo Central Station (Oslo S) to the airport - i.e. six trains per hour. Half of the trains originate in Drammen, making five intermediate stops before Oslo S, and again at Lillestrøm. One starts from Oslo S and goes directly to Gardermoen without intermediate stops. Two start from Stabekk with stops at Lysaker, Skøyen, Nationaltheateret and Oslo S. On Saturdays, Sunday mornings and during most of July, Flytoget does not operate the direct trains from Oslo S or Stabekk — only the 20-minute headway all-stop trains. While the services northeast from Oslo S to the airport use the high-speed Gardermo Line, those westwards towards Asker use the Drammen Line built in 1870–72 and the Asker Line; so while the from Oslo S to the airport can be done in 19 minutes, the from Asker to Oslo S takes 26 minutes. The latter does however include stops at five stations: Nationaltheatret, Skøyen, Lysaker, Sandvika and Asker.

Competition is offered from other means of ground transport and by Vy who operate trains from and to the airport. This includes one hourly departure with line R12 of the Oslo Commuter Rail north to Eidsvoll and south to Oslo, Drammen and Kongsberg; two regional trains (line RE10 and RE11) hourly north to Eidsvoll and Lillehammer and south to Drammen and Vestfold; and five daily express trains to Dombås and Trondheim calling Oslo Airport Station, including one night train (although the express trains to Trondheim do not accept passengers only travelling between Oslo and Gardermoen).
The price of a ticket to Oslo is NOK 230, though higher if departing from Sandvika, Asker and Drammen. Reduced fares with 50% discount are offered to senior citizens, children, youth under 21 years, students, benefit recipients and military personnel. Flytoget tickets are not valid on Vy trains, and vice versa. Vy tickets are generally cheaper, though not for some groups with reduced fare; for instance students are granted a greater discount with Flytoget than with Vy. Ticket can either be bought at vending machines or as e-tickets; there is no seat reservation.
Flytoget transported 5.4 million passengers in 2007, a 34% market share of airport ground transport. Flytoget boasts a high service quality, with 96% of departures arriving within 3 minutes of schedule and only 0.4% of departures canceled. Part of this is due to the airport express trains receiving priority over other trains in the limited capacity around Oslo. Flytoget was announced to have the most satisfied, and the fourth most loyal customers of all Norwegian companies in 2008, by the customer satisfaction survey conducted by the Norwegian School of Management. The same year Flytoget was declared the best place of work in Norway by Great Place to Work. During the 2007 recruitment half of the newly educated train drivers chose Flytoget over Vy, mostly due to higher wages.
