The SNCF Class BB 60030 diesel locomotives were built by FAMH / Jeumont for the Chemin de Fer Paris-Lyon-Méditerranée (PLM) in 1938. They were powered by Sulzer engines, producing 550 bhp, and weighed 68.5 tonnes.^[1][2]

Three locomotives were built. They were initially given their PLM numbers – 4.DMD.1 to 4.DMD.3, but were soon renumbered into the SNCF numbering system as 040.DD. to 040.DD.3. In 1962, they were renumbered again as BB 60031 to 60033.
