Embodiment Construction

[0030] The figure schematically and partially shows a railway vehicle 10 according to an exemplary embodiment of the present invention.

[0031] Railroad vehicle 10 is used to travel on a railroad that includes at least one tunnel, and typically includes a plurality of tunnels.

[0032] Railroad vehicle 10 includes a shielding system 12 for shielding from pressure waves and is configured to hermetically isolate the interior of railroad vehicle 10 from the exterior of railroad vehicle 10 when pressure wave shielding system 12 is activated.

[0033] The general principles of such a pressure wave protection system 12 are known per se and therefore will not be described in more detail. Such a pressure wave protection system 12 is capable of sealing and isolating any passageway between the interior and exterior of the rail vehicle 10 such that pressure changes on the exterior of the rail vehicle 10 do not affect the interior.

[0034] For example, the pressure wave protection syst...

Abstract

A railway vehicle (10) is intended to run on a railway including at least one tunnel, wherein it includes a system (12) for protection against pressure waves, and is configured to hermetically isolatethe interior of the railway vehicle from the exterior of the railway vehicle when this protection system (12) is activated. The vehicle (10) includes a geolocation unit (16) providing instantaneous geolocation coordinates of the railway vehicle, wherein a database (18) includes fixed geolocation coordinates of an entry point of this tunnel for each tunnel of the railway, and a unit (19) 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.

Description

technical field [0001] The invention relates to a particular system for equipping a railway vehicle for traveling on a railway comprising at least one tunnel. Background technique [0002] When a rail vehicle enters a tunnel, pressure waves are generated which are a source of discomfort for passengers, especially in their ears. [0003] In order to overcome this drawback, prior art pressure wave protection systems are known which are configured to hermetically isolate the interior of the railway vehicle from the exterior of the railway vehicle when the pressure wave protection system is activated. [0004] For this purpose, beacons are usually placed on the railway track close to the entrance and usually the exit of the tunnel. [0005] Railway vehicles then include means for detecting these beacons. When such a beacon is detected, ie when a rail vehicle approaches a tunnel equipped with the beacon, a signal is sent to the driver of the rail vehicle so that they can manual...
