These bogies were designed to resist temperature extremes
ranging from - 40°C to + 40°C. Each of them includes
3 axles, 6 braking units and 3 engines with a power output of
1650 kW each.

Once running, the locomotives on which these bogies will be
fitted on will be able to reach a maximum commercial service
speed of 120km/h. Capable of pulling loads of up to 8000
tonnes, with a power output of 9600 kW, these will be the most
powerful locos in the world.
