The SNCF BB 20011 and SNCF BB 20012 were electric locomotives used for testing, built by Alsthom
between 1985 and 1986. The two locomotives were the synchronous dual-voltage prototypes for Class BB 26000
.
In 1994 the locomotives were re-used for work on the channel tunnel, then converted to standard class BB 22200s in 1995.
locomotives numbers 22379 and 22380 were modified to test dual voltage electric traction equipment, the microprocessor control, and auxiliary variable speed induction motors. 20012 was used to test the combination of pneumatic brake system and electric brake system.
