Crossing the Landwasser Viaduct on a northbound train is quite an experience. One second you're in a dark tunnel and the next you seem to be flying through the air above a bottomless abyss. It's not bottomless of course but on a sunny day when the valley floor is still deep in shadow, it certainly seems that way.
Ge4/4III 651 crossed the structure with train RE1148 from St Moritz to Chur on 12 October 2007.
