   • 1957 August, H. A. Vallance, “By Rail to the Norwegian Arctic”, in Railway Magazine, page 575:

     Snowsheds and snow fences protect the line on either side of Semskfjell, but the country soon begins to lose some of its bleakness, and the tree line is regained at Lønsdal (1,680 ft. above sea-level), where the line is high on a hillside, commanding widespread views of the mountains.
