Scrapped 1936

The PLM 241 B 1 was a high-pressure steam locomotive built in 1929 for the PLM (Chemins de fer de Paris à Lyon et à la Méditerranée) using the Schmidt high-pressure system. It was a 4-cylinder compound design.

The manufacturer was Henschel & Sohn of Germany; it was most unusual for a French railway to buy German technology, there being somewhat less than total trust of Germany at the time. Schmidt and Henschel seem to have been the only sources of suitable technology.

Only one was built. The locomotive was scrapped in 1936.
