uBus is an electric rail vehicle on steel wheels designed for urban and suburban routes on string-rail overpasses with prestressed track structure based on the innovative uSky rail.


All uBus models are controlled automatically and propelled by means of an electric traction drive powered by catenary system or from an on-board power storage device. Electric motors of the traction drive are combined with the wheels into a single unit, the motor-wheel.
