Flywheels are proving to be an ideal form of energy storage on account of their high power density, cycle life and storage efficiency. This paper describes an energy storage system comprising a steel flywheel and mechanical variator, which provides the main drive power for a railcar, and which can be charged up either rapidly at stationary points on the route, or continuously at a constant rate from a primary low power source. By operation on rails at urban speeds, with brake energy recovery, energy losses and consumption are minimised. Comparison is made of energy consumption per passenger km with conventional vehicles. The results of laboratory tests on the energy storage unit are presented, along with the analysis of performance tests on a hybrid flywheel-battery rail vehicle.
