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 the Albula valley and the impressive Landwasserviaduct (1902). The highest point of this fascinating journey is the Oberalp Pass at 2033 metres.
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.
he maintenance of these viaducts is a significant operation and work of art as well, similar to the works by Christo Vladimirov Javacheff or Christo (1935) (Source and further information: www.glacierexpress.ch).
