The first proposals to extend the Lademoen Line from Buran to Lade was launched in 1924, as part of a zoning plan for Ladehammeren.

The proposed tramway route would follow a more direct path, and some people at Ladehammeren would get a longer walk to the tram.

The Lade Line was considered by the politicians on 27 June 1957, after recommendation from the board of Trondheim Sporvei, and supported with 66 votes against 9.

The route would demerge from the Lademoen Line at Mellomveien, just before the Voldsminde Loop, which would be rebuilt to a four-lane road, 18 m (59 ft) wide.

A passing loop and stop were located at Ringve School, before the line continued along its own right-of-way parallel to Olav Engelbrektsons allé to the terminus at Fagerheim.
