The line includes the Stavne Bridge over the river of Nidelva, Lerkendal Station and the 2.7-kilometer (1.7 mi) long Tyholt Tunnel.

Construction of the line started during the Second World War by the Wehrmacht, the German military occupying Norway, in an attempt to make the railway in Trondheim resistant to sabotage.

Because of the long construction time of the tunnel, tracks were laid in the city streets, but neither route was completed before the end of the war.

[2] During the German occupation of Norway as part of the Second World War, the Wehrmacht wanted a railway route past Trondheim which was guarded against sabotage.

However, construction of the tunnel took much longer than expected, so instead Wehrmacht started laying railway tracks in the streets in Trondheim.

They planned that the railway would branch from the Dovre Line at Skansen Station and then follow Sandgata and Olav Tryggvasons gate, cross Nidelva on Bakke Bridge and then run up Innherredsveien before reaching the Meråker Line at Lademoen Station.

The line was officially opened on 1 June 1957 and revenue traffic started the following day.
