The Nordland Line is a 729-kilometer (453 mi) railway line between Trondheim and Bodø, Norway. It is the longest in Norway and lacks electrification. The route runs through the counties of Trøndelag and Nordland, carrying a combination of commuter, long-haul passenger and freight trains. From Trondheim Central Station to Steinkjer Station the line is most heavily used, with hourly services by the Trøndelag Commuter Rail. There are three branch lines—the Stavne–Leangen Line at Leangen Station, the Meråker Line at Hell Station and the Namsos Line at Grong Station.
