context_page_description: SNCF's CC 7100 class are part of a series of electric locomotives built by Alsthom. The prototype 'CC 7000' 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 on 21 February 1954, and CC 7107 reaching 331 kilometres per hour on 28/29 March 1955.
context_section_description: The CC 7100 class were the first SNCF high-speed locomotives in which all the axles were motorized, i.e. with powered bogies rather a rigid frame. As delivered their top speed was 150 kilometres per hour (93.2 mph).
  The CC 7100 were contemporaries of the 2D2 9100 for express passenger service on the PLM. From the outset it was apparent that bogie locomotives represented the future and so only a third of the anticipated 2D2s were built, in favour of the CC 7100.
