The northbound train R 1636 of the Rhaetian Railway (Bernina line) from Tirano to St.Moritz is passing the divide between the Mediterranean Sea (Adriatic Sea) and the Black Sea, near the dam wall of the Lago Bianco (white lake), on 2235 meter a.s.l. The "Allegra" railcar ABe 8/12 is pulling 7 passenger cars, including 2 panorama cars of the "Bernina Express", which are surplus in wintertime. Above the second panorama car there is a yellow sign, marking the divide towards Poschiavino-Adda-Po (-Adriatic Sea) (to the south) and Ova da Bernina-Flaz-Inn-Danube (-Black Sea) (to the north-east). The view is from the Lagalb mountain, 2890 meter a.s.l. In the left foreground is the Bernina pass road.
