The oldest locomotive of the Rhaetian Railway in regular service (not historic vehicle), Ge 4/4 I # 603 "Badus", built in 1947, pulls the nostalgia train "Zügen Schlucht" over the 89 meter high and 210 meter long Wiesener viaduct, bridging the Landwasser creek near Davos Wiesen. The viaduct was built between 1906 and 1909 and has a main span of the parabolic bow of 55 meter. The nostalgia train Zügen gorge run two time a day in summertime between Davos Platz and Filisur and vice versa, replacing a timetabled "Capricorn" train with a little longer journey time. Last summer, every other week a "Rhaetian Crocodile" Ge 6/6 I pulled the train, but in the moment both of them, # 414 and # 415 are out of service due to cracks in the wheels.
