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 15000 with the BB7200 and BB22200 series and have even a great deal in common with cabs of other SNCF locomotives of the 1960s. This class was also the first to introduce the VI ("Vitesse Imposée") cruise control system which is now standard on all SNCF locomotives delivered after 1971. The electrical part consists of a single pantograph (type AM18U) which collects 25 kV from the catenary. Power is passed through a transformer which lowers the tension to about 1500 V AC and a bridge rectifier controlled by thyristors rectify it into DC, which is then fed into the traction motors.
