There are many avalanches between Realp and Oberwald. The section over the Furka Pass used to be closed during winters. The mountain section was closed in the winter of 1981 and was replaced by a tunnel (length: ) in 1982. The association called Verein Furka-Bergstrecke and the company Dampfbahn Furka-Bergstrecke now run a heritage railway with steam locomotives on the old route.
