there was no railway, which is the case along the Bothnia Line. The total improvement cost for the Ådalen Line was 6 billion SEK. Old main line The Main Line Through Upper Norrland from Bräcke to Boden was built between 1880–1895. It was deliberately built inland from the coast to protect it from military attacks. The Bothnia Line replaced all passenger traffic on the Main Line Through Upper Norrland between Bräcke and Vännäs, ending service to the stations at Långsele and Mellansel. The line remains in use by freight traffic and occasional diversions of passenger trains during engineering works. North Bothnia Line The North Bothnia Line (Norrbotniabanan) is a planned extension of the Bothnia Line north of Umeå to Luleå. The distance is about , longer than the Bothnia Line. The preliminary decision to build the line as far as Skellefteå has been made. Construction began in 2020 on the first section of the line from Västerslätt in Umeå to Sävar. Both the North Bothnia Line and the Bothnia Line will have the advantage of immediately reducing the cost of the frequent and heavy freight traffic when finished. They will provide large travel time reductions for passengers compared to buses; for example, travel time between Umeå and Luleå may be reduced by at least 1.5 hours.
