Method and system for providing electrical energy for rail vehicles on a rail network

The method involves determining current moving rail vehicles (6,8,10,12,14) of rail network (EB) and detecting their driving parameters. The load condition (L) and/or load distribution in rail network are determined. The speed of rail vehicle is decreased during optimum load state and/or load distribution while increasing speed of rail vehicle on planned scheduled routes. An independent claim is included for system for providing electrical energy rail vehicles.
