From 1905 to 1948, the train made a stop there between Saint-Brieuc and Moncontour. The inhabitants of the Grèves used it frequently to get around and transport goods, particularly bricks produced by the nearby factory. It was called the "Petit train des Côtes-du-Nord", the former name of the department, because there was only 1 m spacing between its rails compared to 1.435 m on a normal track.
