Union of Soviet Socialist Republics (USSR): F

Between 1959 and 1960, the French industry delivered 50x AC (alternative current) electric locomotives. Designated as "F" locomotives (from "Franciya" - France), they are divided in 3 groups:
- 30x freight locomotives, registered F 01 - 30 (can operate in multiple units);
- 10x mixed usage locomotives, registered FR 01 - 10 (identical to freight locomotives but equipped with regenerative electric braking - "R" stand for "Rekuperatsha");
- 10x passenger locomotives, registered FP 01 - 10 ("P" stands for "Passajirs"; these units cannot operate in multiple units).

The mechanical parts are inspired by those of the CC 7100 electric locomotive of the French National Railways (SNCF).

In order for them to operate in temperatures ranging from -50 to + 40 ° C, almost all of the pneumatic equipment had to be reassembled in the body. As a result, the body has been significantly lengthened.

The bogies, with a welded tubular frame, are linked to the body by two oscillating pivots with elastic recalls. These pivots provide the secondary suspension in conjugation with helical springs and sliding pads. The primary suspension combines coil springs and leaf springs; the roller axle boxes are linked to the bogie frame by radial links.

Engines are nose-suspended on the freight and mixed locomotives; they are fully suspended on passenger locomotives.

The wheelbase of a bogie is 4.845 m on passenger locomotives and 4.670 m on the others.

Mixed and freight locomotives are ballasted by means of two thick metal plates welded to the body sides.

The roof, which can be completely dismantled between the cabin partitions, has five skylights. The two placed at both extremities serve as a base for the pantos support boxes, required by the great installation height of the Russian catenary; they also support the fans of the traction motors. "Miofilters" for the air intakes are installed in the long sides. In winter, the outside air intakes are closed and the air necessary for ventilation is taken from inside the body. Heating resistors are provided in the ventilation circuits, so that the motors, then operating in a closed circuit, ensure their own heating. All three versions of the F-Series feature ignitron rectifiers and the Westinghouse compressed air brake. Note some peculiarities specific to Soviet equipment: insulation of the driving cabins, air-conditioned by glass wool in the walls; double front windows; right-hand drive ; runners mounted in the body with an opening in the roof; equipment for continuous repetition of the so-called "auto-stop" automatic signaling; SA3 automatic coupling, of the Willison type.

During the tests in France, the F 01 locomotive towed a 2,500 t train!
