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 10003 The locomotive SNCF BB 10003 was an experimental prototype locomotive converted from a SNCF
SNCF Class Y 8000 SNCF Fret livery. The locomotives also are certified for use in Italy, limited to shunting work: Y 8120 has been operated by SNCF subsidiary "CapTrain Italia". After 1989 production shifted to a mechanically identical Y 8400 type, which incorporated a radio control system for shunting. SNCF Class Y 8000 The SNCF Class Y 8000 is a class of diesel shunter built between 1977 and 1990. The locomotives were developed by SNCF for shunting duties. Initial construction was by Locotracteurs Gaston Moyse until that company ceased business, then by Fauvet Girel. Y 8000 machines were used to replace older shunting engines,
