The CC 14100 is a series of heavy, six-axle electric locomotives operated by the French state railways Société nationale des Chemins de Fer Français (SNCF). The locomotives were used for heavy freight trains in the north and east of the country from the mid-1950s.

A special design feature of the CC 14100 is the position of the driver's cab in the middle of the vehicle. The two pantographs are attached by a projecting support structure above the driver's cab. In order to enable the view from the driver's cab, the locomotive has long hood-like stems at the front and rear , similar to the crocodile locomotives . Unlike the crocodile locomotives, the CC 14100 has a mono frame and no articulated frame. The four-axis sister series BB 12000 , BB 1300 , which were also manufactured in the 1950s, have a design similar to the CC 14100 . A conceptual predecessor is the heavy CC 1100 shunting locomotive , which was built from 1937 to 1948. The unusual appearance has earned the entire BB and CC series the nickname “iron” (fer à repasser). In the beginning, the locomotives were painted blue, later they were given a green color with a yellow front.
Electrical engineering
Until the early 1950s, the power supply of the electrical rail network in France was provided solely by direct current. The SNCF wanted to gain experience with an alternating current system and decided to carry out a large-scale test on the line from Thionville to Valenciennes . This route lay outside the other main arteries, it was hilly and it was an important connection in freight trains for the heavy industry in the region. It was decided to use single-phase alternating current with 25 kV / 50 Hz. The experiment was successful. It led to further routes being operated with alternating current and the country now has two different systems. When selecting the locomotives, a large-scale trial was also carried out and four different electric drive solutions were procured, two each for the four-axle (BB 12000, BB 13000) and two each for the six-axle (CC 14000, CC 14100) series.
The electrical equipment of the CC 14100 was supplied by Alsthom . A transformer first reduces the input voltage from 25,000 V to 3,000 V. Then a synchronous motor is driven, which is mechanically firmly connected to two direct current generators. The direct current feeds the six traction motors connected in parallel. The drive has proven itself for heavy freight trains in hilly terrain. The good controllability and the smooth start-up were also praised. The low maximum speed of 60 km / h was accepted. During tests, the CC 14100 pulled a train with a weight of 1850 tons a ramp with an 11 ‰ gradient and a train with 3500 tons a ramp with 5 ‰. Previously, steam locomotives had to be used in double traction in freight trains on the connection from Thionville to Valenciennes .

The locomotives were delivered between 1954 and 1958. They were mainly used to transport raw materials such as coal, iron ore, coke, lime and bulk goods such as steel and scrap between the industrial centers in Lorraine and northern France. With the decline of heavy industry in the region from the mid-1970s, the volume of transport also declined. The locomotives were considered reliable but slow. It was also said that the locomotives were quite noisy. There is an externally identical six-axis CC 14000 series , which has a fundamentally different electrical engineering and of which only 20 copies have been built. This series was considered to be much more susceptible to failure. After more than 30 years in service, the CC 14100 were gradually replaced by new machines from the mid-1980s, such as E.g .: BB 25100 , BB 22200 and BB 26000 .
The national railway company of Luxembourg CFL began some electric freight locomotives of the four-axle BB type. There they were numbered BB 3600 to 3619.
