Gotthard Line The Gotthard line was built 1872-1882 for the north-south traffic through the Alps. The image shows a section north of the Gotthard tunnel. It has a loop tunnel and a serpentine when climbing up the mountain side at Wasen. (Map from Uppfinningarnas bok. GIF-image 21k.) Sorry for the bad image quality, the image was difficult to scan.
