The French SNCF electric locomotive CC 40101 from 1964.
The SNCF CC 40100 was a French class of quad-voltage 4,340 kW (5,820 hp) electric locomotives. They were intended for high-performance passenger services on the Trans Europ Express (TEE) routes of the 1960s and 1970s. This non-stop international working required them to support the electrical standards of several networks. They are significant for combining three innovations in locomotive design: quad-voltage working, three-axle monomotor bogies and the new ‘Nez Cassé’ body style of French locomotives.
