First Claim
1. A railroad network comprising:
- a track,a network energy supply, anda plurality of trains, each train comprising;
a plurality of vehicles,a propulsion unit able to generate electric energy by braking,an internal electric energy storage system designed to store electric energy originating from the propulsion unit of the train and from the network energy supply, and to supply electric energy to the train and to the network energy supply,a set of ancillary equipment, anda connector connecting the train to the network energy supply, the train being energized when the train is connected to the network energy supply via the connector, the internal electric energy storage system of the train being connected to the network energy supply, and powered down when the train is not connected the network energy supply, the train being able to switch between an operational state in which the set of ancillary equipment of the train is connected to the network energy supply or to the internal electric energy storage system of the train and the train is configured for moving along the track, and an idle state in which the set of ancillary equipment of the train is disconnected from the network energy supply and the internal electric energy storage system and the train is unable to move along the track,wherein one or more trains are in the idle state and energized at the same time, the internal electric energy storage system of the one or more trains in the idle state and energized at the same time being connected to the network energy supply,one or more trains being in the operational state, the one or more trains in the operational state being distinct from the one or more trains in the idle state and energized,the one or more trains in the idle state and energized being configured for storing all or part of the electric energy generated by the one or more trains in the operational state in the internal electric energy storages system of the one or more trains in the idle state and energized,all or part of the electric energy generated by the one or more trains in operational state being transferred via the network energy supply,the one or more trains in the idle state and energized being configured for supplying, via the network energy supply, all or more part of the electric energy stored in the internal electric energy storage system to the one or more trains in the operational state.

Abstract
A railroad network (10) having a track (12), a network energy supply (14) and a plurality of trains (16) that are connectable to the network energy supply (14) via means (20) for connecting the train (16) to the network energy supply (14) and each have an internal energy storage system (24) for receiving and storing energy originating from said train (16) or from trains (16) of the railroad network (10) and for supplying energy to said train (16) or to trains (16) of the railroad network (10). Each train (16) is able to switch from an operational state in which it is able to move along the system of rails (12) and an idle state in which it is unable to move along the system of rails (12) and vice versa.
At least one of the trains (16) of the railroad network (10) is in the idle and energized state at the same time, its internal energy storage system (24) being connected to the network energy supply (14).
