These locomotives, assigned to freight activity and attached to the
Chambéry depot, were used exclusively on the
Maurienne line for
banking freight trains. They ran exclusively as paired units. By 2005, the end of their career related to the reorganization of
Fret SNCF and pushed them quickly towards withdrawal. Banking locomotives became less necessary with the introduction of the more powerful
Class BB 36000. If the occasion arose, a
Class BB 7200 was used. ==See also==
