Norway's longest is the Nordland Line, which runs 734 kilometres (456 mi) from Trondheim to Bodø.
[1] As of March 2010, the system consists of 241 kilometres (150 mi) of double track, 2487 bridges, 695 tunnels, 3514 level crossings and 358 stations.
For those lines that have the full route in operation, the distance is the current length, while for lines that have been closed partially or in full, it is the length at the time of the opening.
For those railways that have been closed in full, the date of the closing (the first date without permitted revenue transport) is stated, along with if the track remains or not, and if the line has been taken into use by a heritage railway.
This column also states if part of the railway has been closed for revenue traffic.
