A protection system of a railway vehicle traction system includes an electric motor and an electrical power supply circuit. The system further includes: a mechanical coupler between first and second components of a transmission line, the first component being connected to an output shaft of the electric motor and the second component being connected to an input shaft of an axle of the railway vehicle, the coupler being able to be in an engaged or disengaged state; and a controller able to apply a disengagement signal to the coupling signal, to switch from the engaged state to the disengaged state if a failure of the power supply circuit and/or the electric motor is detected.

Protection system of a railway vehicle traction system, associated transmission line and associated railway vehicle

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