Smørstein Tunnel
From Wikipedia, the free encyclopedia
The Smørstein Tunnel is a 288-meter (945 ft) railway tunnel located at Smøstein in Holmestrand, Norway. The tunnel carried a single, electrified track of the Vestfold Line. The need for a tunnel arose after a 19 August 1918 landslide washed away the railway past Smørstein. A temporary track was in place from 28 October, but the Norwegian State Railways (NSB) determined that the geology was too unstable and thus decided to build a tunnel to avoid the poor geological conditions. The tunnel opened on 25 May 1921 and was until 2010 the only tunnel on the Vestfold Line between Drammen and Larvik. The tunnel and the section of line was scheduled to be closed in 2016 with the opening of the Holmestrandsporten tunnel.[1]
