Railway vehicle comprising a perfected system of protection against pressure waves

A protection method of protection against pressure waves in a railway vehicle traveling on a railway including at least one tunnel, the railway vehicle having an interior and having a pressure wave protection system configured to hermetically isolate the interior of the railway vehicle from an exterior of this the railway vehicle when the pressure wave protection system is activated, the railway vehicle including a geolocation system providing instantaneous geolocation coordinates of the railway vehicle, a database comprising fixed geolocation coordinates of an entry point of the at least one tunnel for each of the tunnels of the railway, a comparator paring configured to compare the instantaneous geolocation coordinates with the fixed geolocation coordinates to indicate when the instantaneous geolocation coordinates of the railway vehicle correspond to the fixed geolocation coordinates of the entry point of one of the at least one tunnel, and at least one access door configured to be accessed from the exterior, said at least one access door being provided at a periphery thereof with at least one inflatable seal, the pressure wave protection system including an inflation device configured to inflate each of the at least one inflatable seal, the protection method comprising:

• providing the railway vehicle;
• geolocating the railway vehicle to provide instantaneous geolocation coordinates of the railway vehicle;
• comparing the instantaneous coordinates with the fixed geolocation coordinates of each of the entry points;
• and
• inflating each of the at least one inflatable seal, when the comparator indicates that the instantaneous geolocation coordinates of the railway vehicle correspond to the fixed geolocation coordinates of the entry point of one of the at least one tunnel.
