Arlandabanan is a 19 km railway line that leaves Norra Stambanan at Skavstaby south of Rosersberg via Stockholm-Arlanda Airport and then back to Norra Stambanan at Myrbacken north of Märsta. The railway is used only for passenger trains to the airport, and was opened in 1999. The section under the airport is a 5 km long tunnel, the longest railway tunnel in Sweden (excluding Stockholm Metro). There are three stations at Arlanda, Arlanda North, Arlanda South, with high platforms for Arlanda Express, and Arlanda Central, with normal Swedish platform height.
The main user of the line is the Arlanda Express, but also other services, including regional trains to Gävle, Linköping and Eskilstuna use the line, as does the express trains to Falun, Sundsvall and Luleå. The North and South stations are served by the Arlanda Express while the Central station is served by other trains.
The railway was built as a Public-Private Partnership with the line being financed and built by A-Train, who also operates the Arlanda Express. After the finish of the line, the ownership was transferred to the Government of Sweden (but not to Banverket) while the maintainace is to be performed by A-Train for 40 years. They have also received an operating concession for the same period.
