Erick Pelletier reported on AtlanticRails that the Chemin de fer de Charlevoix (CFC), aka the Charlevoix Railway, has been sold to Groupe le Massif, a businessman who already owns a ski mountain in Petite-Rivière-Saint-François. It seems he will operate a tourist train over the line, while CN will operate the existing freight operation. CN and Le Massif will jointly pay for track upgrades.
