SNCF's CC 7100 class are part of a series of electric locomotives built by Alsthom. The prototype 'CC 7000' (7001 & 7002) were built in 1949 and the production series locomotives CC 7101-CC 7158 followed during 1952–1955. Two of the class are notable for setting world rail speed records: CC 7121 reaching 243 kilometres per hour (151 mph) on 21 February 1954, and CC 7107 reaching 331 kilometres per hour (206 mph) on 28/29 March 1955. Developed from the CC 7000 class prototype, these locomotives were the first DC electric locomotives on the SNCF to run at more than 100 kilometres per hour (62.1 mph). During the 1950s, SNCF investigations into high speed rail saw some CC 7100 class locomotives specially modified for operation at speeds far higher than their regular service speed. These experiments provided valuable test data for the SNCF to develop increasingly more rapid regular services, including the 200 kilometres per hour (124 mph) Mistral of 1967, and ultimately the TGV. CC 7121 broke the rail speed record when it achieved 243 kilometres per hour (151 mph) on the PLM mainline between Dijon and Beaune on 21 February 1954. Preparations for further high speed tests proceeded, and
