History: The BB 66000 is a series of 4-axle B'-B' diesel-electric locomotives commissioned by the French state railway SNCF between September 1959 and October 1968 for BB 66000, and between June 1968 and October 1971 for BB 66400. A total of 330 BB 66000 + 106 BB 66400 units have been produced. According to practice of that time, SNCF was the main designer and the locomotives were manufactured by a variety of sub-contractors, with final assembly at Alsthom (now Alstom) in Tarbes and Belfort, France, and Compagnie des Ateliers et Forges de la Loire (CAFL) in Saint-Chamond, Loire, France. These are multi-purpose locomotives, that can be used for passenger service (in multi-unit) as well as freight. They were qualified to run on secondary lines, therefore with a maximum axle load of 18t.
Initially referenced as 040 DG, they have all be renumbered as BB 66000 on January 1st, 1962.
Several are still in service today after several modernizations.

Engine: MGO 16 cylinders
