Gardermoen Line

Gardermoen Line is a high-speed railway in Norway connecting the capital, Oslo, with the country's main international airport. Opened in 1998 to serve the new Oslo Airport, Gardermoen, it represents a major infrastructure project in modern Norwegian history. The line significantly reduced travel times between the airport and Oslo Central Station, facilitating rapid transit for air passengers and regional commuters alike.

History

Planning for a new airport to replace the congested Oslo Airport, Fornebu began in the early 1990s, with the Storting selecting Gardermoen as the site. The decision necessitated a dedicated rail link, leading to the construction of one of Norway's largest post-war public works projects. The project faced significant debate, including the "Battle of the Rails" concerning its alignment versus upgrading the existing Hoved Line. Construction commenced in 1994, involving major engineering works like the Romerike Tunnel, and was completed ahead of schedule for the airport's opening in October 1998. Its inauguration coincided with the closure of Oslo Airport, Fornebu and marked a new era for Scandinavian aviation and rail transport.

Route and stations

The line branches north from the Gjøvik Line at Lørenskog Station, running parallel to the E6 motorway through the agricultural plains of Romerike. Its primary engineering feature is the 14.6 km Romerike Tunnel, one of the longest in Scandinavia, which bypasses the densely populated area around Lillestrøm Station. Key stations include Oslo Central Station, Lillestrøm Station, Oslo Airport Station (Gardermoen), and the terminus at Eidsvoll Station, where it connects with the Dovre Line. The alignment was designed for high speeds, minimizing curves to allow sustained operation at 210 km/h, a significant increase over traditional lines like the Hoved Line.

Infrastructure and operations

Engineered as a modern high-speed corridor, the infrastructure features continuous welded rail on concrete sleepers and utilizes the national 15 kV 16.7 Hz AC system. Signaling is governed by the European Rail Traffic Management System (ERTMS) Level 2, making it one of the first lines in Scandinavia to implement this standard. The line is owned by Bane NOR and sees intensive service from two primary operators: the airport express service Flytoget and the national passenger operator Vy. This dual operation provides frequent connections, with Flytoget offering non-stop trips to the airport in approximately 19 minutes.

Rolling stock

Services on the line utilize specially designed electric multiple units capable of its high speeds. The Flytoget operates with a dedicated fleet of BM71 and newer BM73 units, built by Stadler and Siemens respectively, which are optimized for rapid acceleration and airport passenger comfort. Vy employs its standard regional trains, including the Type 74 and El 18 locomotive-hauled sets, on services continuing beyond Eidsvoll Station to cities like Lillehammer and Trondheim. This rolling stock diversity ensures capacity for both express airport traffic and broader regional travel across Eastern Norway.

Future developments

Future plans are closely tied to the larger InterCity development and the new high-speed project Nordic Triangle. Proposals exist for extending true high-speed lines northward from Oslo Airport, Gardermoen towards Hamar and Lillehammer, potentially integrating with the Gardermoen Line corridor. Studies are also ongoing regarding increased capacity and potential new stations to serve growing communities in Romerike. These developments are part of Bane NOR's strategic vision to enhance rail connectivity across Østlandet and strengthen the airport's role as a national transport hub.
