The North Bothnia Line (Swedish: Norrbotniabanan) is a planned high-speed railway line between Umeå Central Station and Luleå Central Station in Sweden. The line would be 270 kilometres (170 mi) long and be a northern extension of the Bothnia Line, which opened in 2010. The planned extension is expected to improve accessibility between larger cities along Sweden's coast and handle 1.6 million passengers per year. Currently, the area is served by the Main Line Through Upper Norrland, which is located inland and with branch lines connected to various towns along the coast.
