The Thuile locomotive was a steam locomotive designed by M. Henri Thuile, of Alexandria, Egypt, and built in 1899.

History

Thuile proposed a 6-4-8 or 6-4-6 locomotive with 3-metre-diameter (3 m) driving wheels, but it was not built. The design was taken up by Schneider, of Le Creusot, who built a 4-4-6 with 2.5-metre-diameter (2.50 m) driving wheels, and a forward cab for the driver. The two-cylinder locomotive had Walschaerts valve gear and a double-lobed boiler of nickel-steel. The locomotive was exhibited at the International Exposition in Paris in 1900, and the trials were undertaken on the Chemin de Fer de l'Etat line between Chartres and Thouars. A speed of 117 km/h was attained hauling a load of 186 t. The trials ended when Thuile was killed in June 1900, apparently because he leant too far out of the locomotive and hit a lineside pole or a piece of scaffolding supporting an overbridge. The locomotive was returned to Schneider and was scrapped in 1904. The tender survived until at least 1946, when it was noted at Saint Pierre-des-Corps.
