SNCF Class 241P SNCF Class 241P 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. In 1944, SNCF reviewed its predicted postwar traffic requirements and determined a requirement for a locomotive capable of hauling passenger trains of 700–800 tonnes at , and capable of climbing gradients of 1 in 125 (8‰).

SNCF Class BB 20004 SNCF Class BB 20004 The SNCF class BB 20004 locomotive was a dual-voltage test-bed locomotive transformed from the damaged BB16540 in 1959. After the end of its test period in 1969 it was reinstated with its original equipment under its original number BB16540. SNCF had already experimented with three other dual-voltage locomotives in the 1950s, but these were all rebuilt from a DC locomotive and could only deliver their full power under 25 kV. Power output under 1.5 kV was reduced to 10% of the full power which is nearly negligible. This was however no real problem, as these locomotives
