This invention concerns a railway vehicle (), including: a power supply device (), an electrical traction engine (), first electrical auxiliary equipment (), and a connector () for connecting to an electrical power source external to the vehicle. The power supply device comprises: an electrical converter () suited to supply the electrical traction engine with high-voltage current, wherein the electrical converter is connected to the connector; a first medium-voltage electricity network () to which the first auxiliary electrical equipment is connected, and a first electrical storage element () connected to the first medium-voltage electricity network so as to supply electricity to or draw electricity from the first network. The electrical converter is connected to the first medium-voltage electricity network so as to supply the first network with electricity.

Railway vehicle equipped with an electrical storage body

The railway vehicle is intended to run on a railway including at least one tunnel, wherein it includes a system for protection against pressure waves, and is configured to hermetically isolate the interior of the railway vehicle from the exterior of the railway vehicle when this protection system is activated. The vehicle includes a geolocation unit providing instantaneous geolocation coordinates of the railway vehicle, wherein a database includes fixed geolocation coordinates of an entry point of this tunnel for each tunnel of the railway, and a unit for comparing the instantaneous coordinates with the fixed coordinates, and wherein it is configured to indicate when the instantaneous geolocation coordinates of the railway vehicle substantially correspond to the fixed coordinates of the entry point of one of the at least one tunnels.
