Abstract
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.
