An electric vehicle receives electrical power continuously from a remote source, e.g. from live conductor rails or overhead wire, and comprises an electric motor, a flywheel, means to drive the flywheel from the electric motor, and means to propel the vehicle from the flywheel with or without the electric motor. As shown, the vehicle collects power from the overhead wires 11 by pantographs 12 for electric motor 21, which may be used to drive wheels 22 directly and is used to drive the flywheel 23 via automatic gearbox 24. Flywheel 23 may be used to drive wheels 22 via gearbox 25, independently of or in combination with the electric motor 21. |
