The SNCF class BB 15000 is a class of 25 kV 50 Hz electric locomotives built by Alstom and MTE between 1971 and 1978. Initially 65 locomotives strong, the class was widely deployed on the whole French 25 kV network before being replaced by TGV trains when the LGV Est went into service in 2007.

The electrical power equipment is directly derived from the first machines using Jacquemin concepts, the BB 12000: 25kV / 15kV auto-transformer, auxiliary transformer and traction transformer, rectifiers with ignitrons, later replaced by silicon diodes, and smoothing chokes, shunt resistors on the inductors of the 4 traction motors, and Arno three-phase converter to supply hotel power.
The SNCF Class BB 8500 class are part of a series of electric locomotives built by Alsthom for SNCF. They are the direct current version of the 25 kV alternating current SNCF BB 17000 and dual system SNCF BB 25500. The locomotives are fitted with monomotor bogies with two different gear ratios. This allows them to increase their tractive effort ...
Each locomotive had over 5,000 metres (16,000 ft) of wire for the series-wound electric motors. The driver would start the engines in series , with only 1 ⁄ 4 voltage applied at 350 A. The resistance applied to the engines was progressively removed and the locomotive's speed increased, then switching to series-parallel operation and finally ...
The CC 21000 was a class of electric locomotives in service with the French railways SNCF, built by Alsthom in 1969 and 1974. It was a dual voltage version of the CC 6500 class working off both 1500 V DC and 25 kV 50 Hz AC.
The BB 22200 is a class of electric locomotives in service with the French railways SNCF, built by Alstom between 1976 and 1986. They are a dual voltage version (1500 V DC and 25 kV 50 Hz AC ) of the BB 7200 and BB 15000 Nez Cassé classes.
