SNCF Class BB 60000 SNCF Class BB 60000 The SNCF class BB 60000 are a class of 4 axle heavy shunting and light freight diesel electric locomotives built at the Vossloh Espana works in Valencia. Since the class is primarily used as a freight locomotive the class is commonly referred to as SNCF BB460000. SNCF made an initial order for 160 locomotives in 2004. The manufacturer's designation is GA 1000 AS. Two further machines have been ordered (2009) by Egenie of France. At the end of the 1990s SNCF was faced with a diesel locomotive fleet of which the larger part was older than
SNCF Class BB 26000 simplicity of equipment, and price. Two locomotives SNCF BB 20011 and 20012 were used to develop and test the dual voltage traction system, microprocessor control systems and auxiliary motors, BB 20012 was used to develop and test the pneumatic and electrical braking system. The Paris-based industrial design group MBD Design contributed to the design of the locomotive. 264 of the class were ordered by SNCF, only 234 were built, the last 30 of the order were instead built as a new triple voltage design capable of also operating on 3 kV DC; these used asynchronous electric motors and became the
