Railcars ABe 4/4 # 54 and # 51 (called Tw III) in multiple control are pulling the regional train 1625 from St.Moritz over the Bernina pass to Tirano. The train has 2 first class standard cars of type IV in the consist, which is rather special. The train is near the continental divide between Inn/Danube/Black Sea and Poschiavino/Adda/Po/Adriatic Sea (Mediteranean Sea), in the background is 3246 meter high Piz Ot, north of the Engadine. Above the train are several new installed Kreuzkolktafel, which serve to form a deflation basin (blowout behind a snow drift).
