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 25kV 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 in exchange for a reduction their top speed. This makes them suitable for both freight and passenger trains.
