History The locomotive BB 10003 was created from an earlier experimental machine BB 7003 in 1982. It was used to test the use of aysnchronous induction motors in locomotives.[note 2][3][2] From 1986-7 the locomotive was used in experiments testing the viability of a diesel electric locomotive with asynchronous traction motors; the locomotive was coupled to a remotorised SNCF CC 72000 locomotive which acted as an electrical generator.[1] In 1990/1 the locomotive was used as a test machine for operations of the TGV-TMST on 750 V and 3000 V.[4] In 1998 the locomotive was converted back to a non-experimental class - as SNCF BB 15007. (SNCF Class BB 15000)[3][4] Legacy 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),[2] and later the BB 36000 Astride (1996).

A contemporary prototype, the BB 10004 which was used to test synchronous motors gave better results with the available technology (lower mass, and an easier implementation of regenerative braking) was preferred, and led to the SNCF BB 26000 class.[2] References "BB 10003". fc30.pagesperso-orange.fr (in French).
