The Chemin de Fer d'Emosson is a 600mm Decauville line on the Franco-Swiss border. It was originally constructed in 1920 as part of the Emosson hydroelectric dam project, was closed and lifted, and has since been reborn as a tourist attraction.
The line runs for 1,9 kms along a narrow shelf from Chateau d'Eau, at 1813 m, through 5 tunnels and via 4 passing loops to the base of the Emosson dam.
