SNCF Class BB 10003 locomotive was used as a test machine for operations of the TGV-TMST on 750 V and 3000 V. In 1998 the locomotive was converted back to a non-experimental class - as SNCF BB 15007. (SNCF Class BB 15000) The results were not as good as synchronous motor technology; it was not until the introduction of GTO transistor technology that series production of an asynchronous induction motored locomotive began in France, as the "Eurostar" TGV (1992), and later the BB 36000 "Astride" (1996).

SNCF Class BB 75000 reduce emitted particulates). This will change the external appearance of these locomotives. All new locomotives built thus will be numbered from 200 onwards, i.e., BB 475200 and upwards in number. SNCF Class BB 75000 The SNCF BB 75000 (also known as the SNCF BB 475000) are 4 axle, Bo′Bo′, diesel electric locomotives ordered in 2000 by SNCF for freight operations to renew its aging fleet. The locomotives are also classified as Prima DE30BAC They are similar in appearance to the SNCF Class BB 27000, but are in fact the result of a collaboration between Alstom and Siemens.
