The SNCF BB 75000 (also known as the SNCF BB 475000) are 4 axle diesel electric locomotives ordered in 2000 by SNCF for freight operations to renew its aging fleet. The locomotives are also classified as Prima DE30BAC
They are similar in appearance to the SNCF Class BB 27000, but are in fact the result of a collaboration between Alstom and Siemens. The internal electrical components are similar to those found in the Siemens 'EuroSprinter' made for ÖBB; the Rh 2016, and the bodyshell, bogies and other equipment being of the Prima type made by Alstom.
