Construction and use

The locomotives were built in three batches. The first, of 20 units, was built between 1967 and 1968 and allocated to the depot at Chalindrey.These were numbered BB 25151–BB 25170. In 1974 a further 5 units, numbered BB 25171–BB 25175, were constructed and allocated to Chambéry. These were slightly longer and heavier than the first batch. Finally another 20, numbers BB 25176–BB 25195, were built between 1976 and 1977 and also allocated to Chambéry.[1]

The Chambéry locomotives were principally used on the Bellegarde to Evian-les-Bains and Aix-les-Bains to Saint-Gervais-les-Bains services. In the winter sports season Chambéry would be allocated BB 25168 and BB 25169 from Chalindrey to assist with the extra traffic.[1]

In 2009 the last members of the class were transferred to the depot at Venissieux for use around Lyon.

Disposal

In 2003, BB 25180, BB 25184, BB 25194 and BB 25195 were rebuilt to Class BB 25200. Withdrawals of the remainder started in 2003 and continued until December 2011. BB 25188 was reinstated in February 2012, finally being withdrawn in December 2013.[2]

Names

One member of the class, BB 25175, was named Le Creusot.[1]

Preservation

Two members of the class have been preserved, BB 25188 at Chambéry, and BB 25173 at Mini Rail Nantais.
