The A1A A1A 68000 is a series of 6-axle A'1A'-A'1A' diesel-electric locomotives commissioned in June 1961 by SNCF (Société Nationale des Chemins de fer Français / "French National Railway Company"), which manages the rail traffic in France and the Principality of Monaco. These multi-purpose locomotives were used for passenger as well as freight service and retired in 2014.
