SNCF Class BB 10003
Encyclopedia
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.
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.
In 1990/1 the locomotive was used as a test machine for operations of the TGV-TMST on 750V and 3000V. In 1998 the locomotive was converted back to a non-experimental class - as SNCF BB 15007. (SNCF Class BB 15000

SNCF Class BB 15000
The SNCF class BB 15000 is a class of 25kV 50Hz electric locomotives built by Alsthom and MTE between 1971 and 1978. Initially 65 locomotives strong, the series was widely used on the whole French 25kV network before losing services to TGV trains when the LGV Est went into service in...

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.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.
In 1990/1 the locomotive was used as a test machine for operations of the TGV-TMST on 750V and 3000V. In 1998 the locomotive was converted back to a non-experimental class - as SNCF BB 15007. (SNCF Class BB 15000

SNCF Class BB 36000
The SNCF Class BB 36000 locomotives are a class of triple voltage 4 axle Bo'Bo' electric locomotives built by GEC-Alsthom between 1996 and 2001 for SNCF. Initially only to be a tri-voltage version of BB 26000 locomotives, it was further developed and became eventually a completely new locomotive...
