What is "funival"

The Funival is a gauge funicular railway in Val-d'Isère, France

The Funival starts above ground in La Daille and after a few hundred meters it enters a tunnel ending at the mountain station on top of the Belvarde.
The Funival uses two trains, connected by cables, on a single track. Half way a short section of dual track ( passing loop) allows the trains to pass each other.
