Proposals for a railway through Solør were first launched in 1857, but was not approved until 1890. Work commenced the following year on the section from Kongsvinger to Flisa, opening on 3 November 1893. The section from Flisa Station to Elverum was approved in 1894, but a dispute concerning the route postponed construction for thirteen years. The northern section opened on 4 December 1910. The Solør Line had a major impact on the area, leading to industrialization. Communities such as Flisa, Kirkenær and Roverud grew rapidly because they received stations.
