The most difficult work was through Grubbåsen, near Åsen. The ground consisted of quick clay, which the railway was to pass through in a trench. On 5 May 1900, a landslide filled the trench, killing three navvies. Past the lake of Nesvannet, there was also weak soil mechanics, resulting in the need for piling. One worker was killed after getting hit by a piling log. In Levanger, there was debate as to whether the station should be on the west or east side of the tracks, with the decision falling on the west side. The section from Hell to Stjørdal started revenue service on 1 February 1902. The section from Stjørdalshalsen to Levanger was officially opened on 27 October 1902, with ordinary services starting on 29 October.
