1955
Delivered in 1955, it is the last of the three prototype
locomotives delivered to the French National Railway Company - SNCF to test
the technologies suitable for the single-phase alternating current
electrification. The previously delivered prototypes are:
- the CC 6051 electric locomotive delivered in 1950;
- the CC 6052 electric locomotive delivered in 1951.
Of the three, it is the only machine that can operate at full power from the outset at both 25 kV / 50 Hz AC and 1500 V DC, but it is also undoubtedly the most complex.
Manufactured by the Electric Traction Equipment Company - MTE and the Creusot Workshops, it is mechanically derived from the BBB 6002 unit, a prototype intended for electrification of the Brive - Montauban railway line at the end of the war. The electrical equipment consists of a main transformer of 2'900 kV supplying an asynchronous motor of 3'800 hp operating no less than three direct current generators.
