Netherlands Railways Ltd investigates energy recuperation, storage and re-use on board of electric commuter train sets. Two different types of energy storage flywheel units are being developed on the basis of both conventional and advanced techniques. A reduction of dimensions, weight and internal losses is being pursued by an integrated design of the electric machine and the flywheel mass. The flywheel units will be mounted under the coach of a commuter train set. The load on the bearings of the flywheel units can be limited by the use of a cardanic suspension. In order to increase the benefit of the energy storage system design studies for a refined streamlining of the train sets have been carried out. By the development of a retractable central automatic coupler, which required an extensive design effort, the streamlining of the front ends has been improved considerably. The adaptations described result in an energy saving up to 25%; 308,000 kWh per train set each year.
