The Furka Cogwheel Steam Railway (Dampfbahn Furka-Bergstrecke, DFB in German) is a largely volunteer operated heritage railway which operates a partially rack and pinion-operated line across the Furka Pass, between Realp in Uri and Oberwald in Valais. Culminating at 2,160 metres above sea level, it is an old mountainous section of the Furka-Oberalp-Bahn (FOB) that was abandoned after the construction of the Furka Tunnel. It has been gradually brought back into service by the Verein Furka-Bergstrecke with the use of only steam locomotives, with the entire line completed in 2010. The Furka Railway is the second highest rail crossing in Europe, after the Bernina Railway.
