Shortly after the Second World War, the Establishment Schneider at Le Creusot received an order for 35 powerful new steam locomotives designed to haul trains of 800 tons at 120 kph.
This locomotive type was designated P class and was delivered between 1947 and 1951. The wheel configuration is 4-8-2 ( in French 2-4-1) and the locomotive with tender weighs 216 tons in working order. The four coupled driving wheels are 2 metres in diameter.
The locomotives proved to be very successful and were allocated, principally, to haul heavy express passenger trains on the legendary "Imperial" main line to Marseilles.
They would have hauled the famous Mistral "rapide" between Dijon, Lyon and Marseilles.
241 P 17 entered service on May 10th 1950 and was withdrawn on October 24th, 1969. This locomotive covered 1,741,865 kilometres in commercial service for SNCF, the record of the class.
After withdrawal, the locomotive was returned to Le Creusot where it was stored at the factory where it had been built.
241 P 17 was purchased by the Ville du Creusot and a heritage association (Les Chemins de Fer du Creusot)restored the locomotive to running order during a period of 13 years. It has been classified Monument Historique. Three other P class locomotives have survived; P 9 at Guitres in the west of France, P 16 in the National Railway Museum at Mulhouse and P 30 which, after 30 years exposed in open air at Vallorbe, has been moved to a museum at St Sulpice, Canton de Neuchatel, Switzerland where it is to be restored externally.
