The Train des Pignes is a set of four metre gauge railways that once existed in the departments of Alpes-Maritimes (06), Var (83), Alpes-de-Haute-Provence (04) and Bouches-du-Rhône (13) in the Provence-Alpes-Côte-d'Azur (PACA) région in southern France:
Only the one between Nice and Digne is still in operation. Therefore, today most people when they use the term, unaware of the history, refer to the Nice-Digne Line only.
Pignes is the southern French dialect word for pine cones.
The St. Raphaël - Toulon and Cogolin - St. Tropez lines were also sometimes called Le Macaron.
