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. They decided that the best way to do this was to build a tunnel under the neighborhood of Tyholt. 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. However, by German capitulation on 8 May 1945, construction of the railway had only reached Søndre gate.
