Narrow-gauge railways of France

The French National Railways used to run a considerable number of 1,000 mm (3 ft 3+3⁄8 in) metre gauge lines, a few of which still operate mostly in tourist areas, such as the St Gervais-Vallorcine (Alps) and the "Petit Train Jaune" (little yellow train) in the Pyrenees. The original French scheme was that every sous-prefecture should be rail connected.
