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 47000 SNCF Class BB 47000 The SNCF Class BB 47000 "Prima" electric locomotive is a locomotive, built by Alstom. This locomotive is the quadruple-voltage version of the Class BB 27000. So far, only one locomotive, numbered 47001, has been built and was tested by Fret SNCF with a view for further orders. In 2006 it became clear that SNCF wouldn't order this version anymore and the locomotive had passed on to Alstom as a permanent test bed locomotive for testing different Alstom technologies. In 2009, the locomotive was devoid of all technical components. Its bogies were re-used by the Prima II-prototype.
