SNCF BB 13000 SNCF BB 13000 The BB 13000 class were electric locomotives operated by SNCF in France. They were one of four classes, together with the BB 12000, CC 14000 and CC 14100 classes, that formed an experimental group for studying the practicality of the new French electrification. The standard French electrification system before WWII was 1,500 V DC, beginning with locomotives such as the 2BB2 400. Post-WWII, France occupied the south-west of Germany and the . This line had been electrified with one of the first systems to use 50 Hz, the standard commercial distribution frequency, rather than the lower Hz
SNCF Class BB 10003 SNCF Class BB 10003 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. 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
