Ge 4/4 II # 621 "Felsberg" of the Rhaetian Railway pulls the RegioExpress 1737 from Chur to Disentis/Mustér through the impressive gorge of the Vorderrhein, called "Ruinaulta", between Versam-Safien and Valendas-Sagogn. Behind the locomotive is a cab car BDt "Neva Retica", which is in the train to allow one lowfloor entrance. To protect the front windows of the following control car from sparks and abrasion, the locomotive has lifted the front pantograph, as is the regulation.
