SNCF Class BB 69000 was a class of two prototype high power diesel-hydraulic locomotives numbered BB 69001 and BB 69002. They were built at the same time as the diesel-electric version, Class CC 70000. The use of hydraulic transmission saved 30 tons in weight and enabled the locomotives to run on four axles instead of the six axles of the diesel electric.

These locos should not be confused with Class BB 69200 which was a rebuild of Class BB 66000.

Powertrain

There were two diesel engines and each drove one bogie through a hydraulic transmission unit.
