Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters".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.
History
SNCF BB 26000 test locomotives
In 1985 and 1986 the SNCF BB 22200 locomotives numbers 22379 and 22380 were modified[1] 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.[2]
Channel tunnel machines
In 1994 the units were used in the Channel Tunnel as motor engines for TTU trains.[3][note 1] (Channel tunnel freight engines)[5]
Conversion to standard locomotives
In 1995 the locomotives were converted back to standard SNCF Class BB 22200 type.[3]
Miniature models
The locomotive 20011 has been produced by Märklin[6] and Roco[7][8] in HO scale.
