The
SNCFClass BB 27000"Prima"electric locomotives were built by
Alstom between 2001–2005. These are dual-voltage freight-only locomotives; they are not fitted with a 1500 V DC electrical line for train heating and accessories. One hundred and eighty of the locomotives, numbered 27001–27180, were built for
Fret SNCF, for use on freight traffic. Their introduction led to the withdrawal of several elderly electric types, including Classes
CC 7000,
CC 7100,
BB 8100 and
BB 12000. They have also made significant inroads into Classes
CC 6500,
BB 8500,
BB 16500 and
BB 25500.
They can be seen largely in North and Eastern France and the lines through
Dijon to
Lyon, and the lines to
Rouen and
Caen.
