The design of these locomotives, with their so-called “nez cassé” (broken nose), was created by the Frenchman Paul Arzens, who was responsible for designing several SNCF locomotives around that time. Between 1971 and 1976, Alstom built a total of 65 locomotives. The locomotives are the first French main line locomotives with two driver's cabs that have only one current collector and were the last electric locomotives of the SNCF to be designed only for the alternating current system.
