The SNCF 241.P is a 4-8-2 'Mountain' type express passenger steam locomotive that ran on the Société Nationale des Chemins de fer Français, (French National Railways) from 1948 until 1973. Introduced as large scale electrification of the SNCF was already underway, they were the last new class of passenger steam locomotives in France.
