Locomobile No. 3003, which can be seen at the entrance to the town of Buire and the former railway depot, was manufactured in 1900 by the construction engineer Emile Salmson. Its operating pressure was 7 bars. Property of the Northern Railway Company, it was used to drive the machine tools of the Hellemes Workshops (North). As the SNCF machine tools became autonomous, she ended her career in 1939. It was Monsieur Raclot, director of the Leclerc center, who offered her second youth to the ECO-RAIL association.
