context_page_description: The SNCF CC 40100 was a French class of quad-voltage 4,340 kW electric locomotives. They were intended for high-performance passenger services on the Trans Europ Express 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.
context_section_description: The CC 40100 was the first of Paul Arzens' 'Nez Cassé' designs. These used distinctive forward-tilted windscreens, intended to reduce sun reflections.  As an international locomotive, French practice was that a central third headlight was placed above the windscreens. For the CC 40100 class, the nose below was quite short and so the roofline overhung the nose. Later classes with this design style had a longer cellular bonnet ahead of the driver, which could act as a crumple zone in an accident.
  When first built, the driver's cab had side windows. In common with the other Nez Cassé designs, these were later plated over. Unlike the windscreen itself, these panels had been vertical and gave trouble with sun glare.
  The sides of the locomotives were decorated with ribbed stainless steel panels, described as the 'Inox' livery. These panels were unique to this class amongst the Nez Cassé.
