The Transports Publics du Chablais (TPC) Beh 4/8 591 seen between Le Sépey and Les Planches

This is the only one of the nearby narrow-gauge railways that is not rack-and-pinion, so it has to run into side-valleys to reach its altitude. Already after leaving Aigle it twists into a side-valley, runs along it for a time, rewinds in a tunnel and appears far above the Grande Eau as it gets back in the main valley.
