The RhB Ge 4/4^III 650 UNESCO on the Albulabahn between Muot and Preda

On Karcsi's photo montage the St. Moritz to Chur RegioExpress appears twice: once just after leaving the Zuondra-loop tunnel, he first tunnel after Preda, and second on the Albula-III viadukt. Between the two the train passes over Albula-IV viadukt and takes a U-turn in Maliera-gallery. After viadukt III the trains enter the Toua-loop tunnel to lose a lot of height again to emerge just under the pillars of the viaduct.
