The SNCF 240P class was a group of 37 4-8-0 steam locomotives designed by André Chapelon, and regarded by some, as one of his best designs.
They started life as Chemin de Fer de Paris à Orléans (Paris-Orleans Railway) 4500 class 4-6-2s before being rebuilt. The new boiler with the long, narrow Belpaire firebox came from the Nord "Super Pacifics". With all the pipes, domes, and pumps, these were double-chimneyed, husky looking locomotives of very different appearance than the Pacifics.
[edit] Use
These 4-8-0s were created to tackle the gradients of the line to Toulouse, steeper than those to Bordeaux. The intention was to provide one-third more adhesive weight than the 4500s. On level ground, they could manage 28 coaches at 53mph (85km/h).
