The Central Line (Swedish: Mittbanan) is a 358-kilometre (222 mi) long railway line between Sundsvall and Storlien in central Sweden (Västernorrland County and Jämtland County). It continues as the 106-kilometre (66 mi) long Meråker Line through Norway to Hell Station and onwards to Trondheim. The railway shares line with Inland Line between Brunflo and Östersund while the line between Ånge and Bräcke is double track. The entire line is electrified at 15 kV 16 2⁄3 Hz AC, but the Norwegian section is not. This requires all trains to Norway to be diesel trains.
