The Compagnie des chemins de fer de Paris à Lyon et à la Méditerranée (PLM) was a French railway company. Created between 1858 and 1862 the PLM operated chiefly in
the south-east of France, with a main line which connected Paris to the Côte d'Azur by way of Dijon, Lyon, and Marseille. The company was also the operator of railways in Algeria. Several of their draughtsman went on to notable careers, including Alfred Grévin. Absorbed in 1938 into the majority state-owned Société Nationale des Chemins de fer Français, the PLM's network became the south-eastern region of SNCF. The PLM domicile in Paris is loctated in Rue Saint-Lazare.
