From Andermatt the train goes forward in the valley called Urseren passing the villages of Hospental () and Realp (). From there the train enters the Furka Base Tunnel, leaving the old railway line which climbs the Furka Pass (operated today by the Furka Cogwheel Steam Railway), to emerge in Oberwald () in the Goms Valley, in the Canton of Valais. The train then continues toward Brig, following the course of the Rhone, and passes along the villages of Ulrichen (), Münster-Geschinen () and Fiesch (), before going through another spiral.
