{{Main|Gardermoen Line}}
Oslo Airport, Gardermoen, is not on the [[Hoved Line|Trunk Line]] that runs north from Oslo. With heavy traffic and many small stops until [[Lillestrøm Station|Lillestrøm]], and continuing north as [[single track (rail)|single track]],<ref name=jbvstat45>{{Cite web|url=http://www.jernbaneverket.no/multimedia/archive/01821/Jernbanestatistikk_1821829a.pdf |author=[[Norwegian National Rail Administration]] |title=Jernbanestatistikk 2007 |year=2008 |access-date=2008-09-13 |page=45 |url-status=dead |archive-url=https://web.archive.org/web/20081217042116/http://www.jernbaneverket.no/multimedia/archive/01821/Jernbanestatistikk_1821829a.pdf |archive-date=December 17, 2008 }}</ref> the Trunk Line would have to be supplemented by a parallel [[double track]] from Oslo, with a new route north of [[Kløfta Station|Kløfta]] to [[Eidsvoll Station|Eidsvoll]], the {{convert|16|km|mi|0}} north of the airport allowing trains operating on the [[Dovre Line]] to [[Lillehammer Station|Lillehammer]] and [[Trondheim Central Station|Trondheim]] to access the airport.

The Gardermo Line was the second attempt to build high-speed rail in Norway, after the {{convert|35|km|mi|adj=on}} line from [[Ski Station|Ski]] to [[Moss Station|Moss]] on the [[Østfold Line]]. But no operation speeds exceeding {{convert|160|km/h|mph}} 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.<ref name=jbvstat6 />

Construction started in 1994.<ref name=history /> An agreement for purchase of sixteen three-car [[electric multiple unit]]s 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,<ref name=elektrolok /> costing [[Norwegian krone|NOK]]&nbsp;1.4&nbsp;billion.<ref name=history />
