SNCF Class BB 25100

The BB 25100 is a class of electric locomotives in service with the French railways SNCF, built by Materiel de Traction Electrique (MTE) in 1967. They are dual voltage locomotives working off both 1500 V DC and 25 kV 50 Hz AC with a top speed of 130 kph. The class was designed by André Jacquemin.

Originally allocated to Chalindrey, they were used on the Dijon to Metz route until supplanted by Dijon-based BB 22200. Subsequently, they operated express passenger and freight services around Dijon and also in the northeast of France. The class was eventually withdrawn by 2006.

4 of the class were sold in 2007 to GFR - Grup Feroviar Român, Bucharest of Romania (25109 and 25123 to 25125). Three have been renumbered to 425 109-2, 425 123-3 and 425 125-8. The fourth loco 25124 is believed to have been purchased by GFR for spares.
