The Sørlandet Line (Sørlandsbanen) is a railway line between Drammen (though this is connected to Oslo by means of the Drammen Line) via Kristiansand to Stavanger. The line is long between Oslo and Stavanger. The railway was constructed in several phases, the first section being opened in 1871 and the last not opened until 1944. While there was a continual construction work from Oslo westward as far as Moi, the Jæren Line from Egersund to Stavanger in Western Norway was opened in 1878. Up to 1913 the name used on plans and for the completed sections was the Vestlandet Line (The West Country Line). The Sørlandet Line was completed by the German occupation force during World War II. It was opened for regular traffic on 1 May 1944. The line was an important communications link for transportation of troops, as well as war material. Long stretches of the Sørlandet Line railway are set away from the coast, instead of on the more densely populated coastline. One reason for this was to protect the line from invading forces, and also to prevent the line being bombarded by navy ships. On 15 November 1950 the Hjuksebø train disaster killed 14 people in a collision between an express train and runaway freight cars. On 15 December 2019 operation of passenger services passed from Vy to Go-Ahead Norge. Since then, Go-Ahead operates its long-haul passenger service between Oslo and Stavanger as Sørtoget ("The South Train"). Among the stretches which make up the Sørland Line are: Oslo–Drammen is the Drammen Line, completed in 1872. Drammen–Kongsberg, opened in 1871. Kongsberg–Bø, opened in 1924. Lunde–Neslandsvatn (Kragerø), opened in 1927. Neslandsvatn–Nelaug (Arendal), opened in 1935. Nelaug–Kristiansand, opened in 1938. Kristiansand–Moi, opened in 1944. Moi (Flekkefjord)–Egersund, opened in 1904. Egersund–Stavanger is the Jæren Line, which was opened in 1878. The Sørlandet Line has one operational branch line, the Arendal Line, which runs between Nelaug and Arendal. Another branch line, the Flekkefjord Line, from Sira to Flekkefjord, was once part of the main line.
