SNCF Class BB 25200

The BB 25200 is a class of electric locomotives in service with the French railways SNCF, built by Materiel de Traction Electrique (MTE) between 1967 and 1976. They are dual voltage locomotives working off both 1500 V DC and 25 kV 50 Hz AC. Designed by André Jacquemin, the class is a development of the earlier BB 25100 and BB 25150 locomotives with a higher top speed, being capable of 160 kph. It is the dual voltage equivalent of the BB 9200 and BB 16000 classes.
