The SNCF Class CC 14100 was a class of 25 kV 50 Hz AC electric centre cab locomotives designed to haul heavy freight trains in the northeast of France and cross-border traffic into Luxembourg. A total of 101 locomotives were produced, numbered CC 14101 – CC 14202.
Introduced at the time when steam traction was being phased out, the torque of these locomotives was exceptional. During tests, a CC 14100 started a train weighing 1,850 tonnes (1,820 long tons; 2,040 short tons) on an 1.1% slope, and a 3,500 tonnes (3,400 long tons; 3,900 short tons) train on a 0.5% slope. Their slow speed of 60 km/h (37 mph) became a liability in later years and by 1986 individual locomotives were being withdrawn as they came due for overhaul or major repairs.[1] The last members of the class survived until 1997, mainly on shunting duties.[2]
