The electrification of the French railway network was made in four phases. First, at the start of the 20th century, there was a phase of testing and technological exploration. Third rails and overhead lines were on trial in some lines in France; different voltages were tried.
In 1909, the Compagnie du Midi launched a vast program of electrification of its lines under the impetus of the engineer Jean-Raoul Paul (1869-1960). It was a huge challenge for the time because it went far beyond the scope of railway operations alone. It was necessary to build infrastructure such as dams, power plants and distribution systems.
Railway electrification is the development of powering trains and locomotives using electricity instead of diesel or steam power.The history of railway electrification dates back to the late 19th century when the first electric tramways were introduced in cities like Berlin, London, and New York City.
A freight train bound for the ArcelorMittal plant in Saint-Chély-d'Apcher crosses the Garabit viaduct. The railway line is currently a single track along its entire length. Previously, it was double-tracked in sections from Millau to Saint-Laurent-d'Olt, and from Le Monastier to Saint-Sauveur-de-Peyre. The route features a challenging profile ...
The locomotives were built by SEECF, the research company for railway electrification. This company, created in 1920, brought together French manufacturers, such as Schneider and Jeumont, and American companies, such as Thomson-Houston, which held General Electric patents.

The four classes each took a different approach to the use of the AC supply current. [1] The first, the BB 12000, used DC traction motors with ignitron rectifiers; the BB 13000 used new 50 Hz AC traction motors; the CC 14000 used DC traction motors with rectification by rotary converters and the CC 14100 used three-phase AC traction motors, again with rotary converters.
The Paris suburban rail services represents alone 82% of the French rail annual ridership. [1] [2] With a total of 100.2 billion passenger-kilometres, [1] [2] France has the fifth-most used passenger network worldwide, and second-most used in Europe after that of Russia. [8] France is a member of the International Union of Railways (UIC).
The advent of High Speed Rail added to the "classical" problems of railway electrification standards, gauge, loading gauge and "classical" signaling the additional problem of train protection systems, which are necessary for any train exceeding the speed limit of legacy signaling (79 mph in the United States, 160 km/h (99 mph) in much of ...
