Abstract
The invention relates to equipment including fixed fire detectors (10) along the track (100) and fixed extinguishing stations (20) installed in the tunnel. Each station is provided with fire detectors (23) for locating the source, an automatic configuration system for targeting the area to be sprayed, individually controlled spraying devices (22), and a device for remotely or locally activating the spray. The station is preceded by a train stopping area (ZA) in which the train (TRO) starts a stopping sequence and slows down from the safety speed thereof to the zero speed thereof. A control center (30) manages the operation of the equipment and in particular orders a reduction of the train (TRO) running speed when the detectors (10) have detected a fire (flames, smoke, CO). The reduced speed (safety speed (Vs)) enables the train (TRO) to run as quickly as possible while mitigating the progression of the fire.
