Abstract
A rail vehicle system that has connecting bogies, supply units, control units, and transportation units, which can be placed on said connecting bogies in order to form a train with a modular construction. The connecting bogies contain at least two axles, one of which is equipped with an electrical drive/brake unit, and which are configured to be separable. The supply units may contain vital devices such as current collectors, transformers and power converters for extracting power form a contact line and feeding it back into the contact line or converters of primary energy into electrical energy. The control units can be configured to be independent of current and load. The transportation units may differ according to whether they are for transporting passengers or goods and according to the type of good being transported. The interfaces of all of the units are uniform and are configured in such a way that the units can be interchanged quickly and easily. The resulting consistent division of train into functional units enables the driving power to be better adapted to the load, creates possibilities for generating and using energy and reduces operating/maintenance costs.
