The Andelot-Champagnole general interest line was extended to St-Laurent-en-Grandvaux, and the Compagnie PLM station was opened in 1890. The Andelot-La Cluse line - which required the construction of a number of structures, including 18 viaducts and 36 tunnels - was completed in 1912. This was also the date when travelling by stagecoach stopped being practiced between St-Laurent-en-Grandvaux and St-Claude, as ensured by Louis Charnu.
