SNCF's BB 25500 class are part of a series of electric locomotives built by Alstom. They are the dual system version of the BB 17000 (AC) and BB 8500 (DC) locomotives (17000+8500=25500). They are fitted with monomotor bogies with two different gear ratios.[clarification needed] This allows them to have increased tractive effort in exchange for a reduction in top speed. This makes them suitable for both freight and passenger trains.[3]

They were built in three distinct batches leading to detail differences. They remain in use as mixed traffic locomotives, mostly with TER and Transilien.

Romania[edit]

Locomotives 25517, 25518, 25523, 25528, 25572 & 25576 have been exported to Romania. They work with former SNCF Rio carriages for Regiotrans.[4] Services worked are:

The locomotives have been renumbered by adding 400,000 to their SNCF numbers.
