The trip of the so-called Glacier Express leads over 291 bridges and through 91 tunnels over the Swiss Alps, from Zermatt and the Matterhorn to St. Moritz. The train finds its ways through remote valleys, sheer rock faces, mountain villages, through the beautiful Rhine Gorge (die Rheinschlucht), the Grand Canyon of Switzerland, and scales the highest point of its fascinating journey at the Oberalp Pass at 2033 metres. One also crosses the Albula valley and the impressive Landwasserviaduct (1902). One of the engineers making it all possible was Richard Coray (1869-1946). He developed a system to overcome the problems of the construction of the long viaducts. The maintenance of these viaducts is a significant operation and work of art by itself, similar to the works by Christo Vladimirov Javacheff or Christo (1935) (Source and further information: www.glacierexpress.ch).
