The JOUEF CC 6500 is a series of electric locomotives of the French National Railway (SNCF), manufactured by Alstom of France. The CC 6500 was the flagship of single-current locomotives in France from the 1970s and was the most powerful locomotive at the time. These locomotives were the most powerful models in a large series of locomotives that later became known as "Nez cassés (broken noses)," and their variations were delivered in France and around the world from 1964 to 1999.
