The line past Drøyliene was originally planned with several viaducts. During construction it was decided to instead build the line as a series of cuttings and six tunnels. Tamlaget Tunnel was the longest, at 204 meters (669 ft). This section opened on 16 January 1877. The original right-of-way through Drøyliene was plagued with rock slides and would fill with snow during winter. Proposals for replacing it with a tunnel were first made in 1924, but work did not start until 1937, in conjunction with the gauge conversion of the railway. The break-through took place in 1943 and the tunnel opened on 7 July 1945.
