The story
Established on 3 July 1857, the PLM grew between 1858 and 1862 from the amalgamation of the earlier Paris–Lyon and Lyon–Méditerranée companies, as well as subsequently incorporating a number of smaller railways. The PLM operated chiefly in the Southeast of France, with a main line which connected Paris to the French Riviera by way of Dijon, Lyon and Marseille. The company was also the operator of railways in Algeria.
The PLM was absorbed in 1938 into the majority state-owned Société nationale des chemins de fer français, and its network became the southeastern region of the SNCF.
