A remarkable improvement in energy management is secured by the use of a simple, but effective, engineering device – the flywheel.
The flywheel allows the direct capture of brake energy (on slowing down or descent) and its re-use on pulling away and acceleration.
And since acceleration is provided by the flywheel, the primary power unit can be small and operated within a narrow and optimal speed range. |

Experiences with smaller railcars indicate a fuel consumption for the 80 passenger vehicle of half that of the equivalent bus.
The small power unit and relatively simple mechanics result in easy maintenance with modest equipment.
