In 1877 the line was joined with the Røros Line, which went through the Østerdalen between Røros and Hamar. In 1884 the railway tracks were relocated to the west side of the Nidelva and joined with the Meråker Line and the new railway station at Brattøra, which had opened in 1882. This went through a tunnel at Nidareid to Brattøra. In 1918 new tracks were laid to Heimdal over Selsbakk.
Gauge conversion
In 1921 the railway was converted to standard gauge and became a part of the Dovre Line.[2]
