The locomotive SNCF BB 10003 was an experimental prototype locomotive converted from a SNCF BB 15000 unit and used to develop the use of asynchronous induction traction motors.
Contents |
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 1][1][3]
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.[2]
In 1990/1 the locomotive was used as a test machine for operations of the TGV-TMST on 750V and 3000V.[4] In 1998 the locomotive was converted back to a non-experimental class - as SNCF BB 15007. (SNCF Class BB 15000)[4][1]
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 asychronous inudction motored locomotive began in France, as the Eurostar TGV (1992),[3] and later the BB 36000 Astride (1996).
