Gardermoen is at kilometer marker 51.85 from Oslo S, but the actual distance is only. This is because the distance markers follow the slightly longer Hoved Line between Oslo and Lillestrøm. The station is built directly below the airport terminal, and access is obtained via escalators or elevators located in the airport's arrival hall. North of the station, the tracks run in a tunnel below the terminal and runway area. The tracks on platform 2 and 3 only have connection southwards; north of the station they are only connected to a short turning track. Aviation fuel is transported to the airport by train. CargoNet hauls a daily train load of fuel from Sjursøya, with an unloading terminal just south of the passenger station. They are the only freight trains to use the Gardermoen Line.
Services

The station is manned, from 07:00 to 22:00 on weekdays, with reduced opening hours on weekends. The platform are wheelchair accessible, and an escort service for disabled persons can be prebooked. Baggage trolleys are available, and a wide selection of services, including cafes, kiosks, banks and police, are available at the airport terminal, as are taxis. A single local bus route, Ruter no. 855, also serves the airport from Kløfta, Jessheim and Maura. There are many coaches from all parts of the country that also serve the airport, as well as coach services to Oslo operated by Flybussekspressen and SAS Ground Services.
The Flytoget airport express train services operate six times per hour. Three run directly to Oslo Central Station in nineteen minutes and terminate there; the other three services make an additional stop at Lillestrøm Station, then continue beyond Oslo Central towards Drammen Station, a total of eight stops. Total travel time to Drammen is 60 minutes. In 2007, the Airport Express Train had 5.35 million passengers.
The decision to build the station, railway and airport was taken by the Parliament on 8 October 1992. NSB Gardermobanen, a subsidiary of the Norwegian State Railways, was created to build the line and station, as well as operate the Flytoget airport express train services. Construction of the station was performed in parallel with the construction of the airport, and the station is built in the same style as the rest of the airport, in postmodernist concrete and wood. The station was taken into use on 27 September 1998, and public services commenced along with the opening of the airport on 8 October 1998. In 2001, as part of a reorganization of NSB Gardermobanen, the ownership of the station was transferred to the Norwegian National Rail Administration.
Incidents
In 2000–01, the Airport Express Train experienced three derailments with empty trains at Gardermoen; one caused by the engineer falling asleep and two by the train passing a red light. No more such accidents occurred after automatic train control was installed in 2001.
