Arlanda Line

The Arlanda Line (Swedish: Arlandabanan) is a 19-kilometre (12 mi) long railway line which allows trains on the East Coast Line to reach Stockholm-Arlanda Airport in Sigtuna Municipality, Sweden. The Arlanda Line branches from the East Coast Line at Rosersberg and rejoins again at Myrbacken. It is built for speeds of 200 kilometres per hour (120 mph), is electrified at 15 kV 16⅔ Hz AC and is double track. The 5-kilometre (3.1 mi) section under the airport runs in a tunnel, and has three stations: Arlanda South Station, Arlanda Central Station and Arlanda North Station.

The Arlanda Express operates six hourly services to Stockholm Central Station, the largest railway station in Sweden and in the Nordic region. Operated by A-Train, the service uses seven X3 trains and calls at the north and south stations. The station is also served by 70 other regional and intercity trains daily, operated by SJ, Tågkompaniet and Upptåget. These all stop at Arlanda Central. In 1994, A-Train was awarded the right to build the line in a public–private partnership, where A-Train paid about half the 6 billion Swedish krona (SEK) to build the line. The line opened in 1999 and A-Train holds the sole right right to operate to Stockholm, and collects a fee from other train operators using the line. The line itself is owned by Arlandabanan Infrastructure AB, which is owned by the Ministry of Enterprise, Energy and Communications.
