RAILWAY-TRAIN EMERGENCY BRAKING APPARATUS, RAILWAY-TRAIN EMERGENCY BRAKING SYSTEM, AND RAILWAY TRAIN PROVIDED WITH RAILWAY-TRAIN EMERGENCY BRAKING APPARATUS

摘要

Provided are a railway-train emergency braking apparatus, a railway-train emergency braking system and a railway train provided with the railway-train emergency braking apparatus, which are capable of causing a railway train running at an extremely high speed to stop after travelling a predetermined distance in cases of emergency such as when an obstacle, person or car exists in front of the railway train in the direction of forward movement thereof and when an earthquake has occurred, the predetermined distance being about the same as a distance conventionally required in such cases. In a railway train (100), each of cars (201 to 206) is provided with at least one or a plurality of jet engine devices (300 and 400). Propulsion from these jet engine devices (300 and 400) is generated toward the direction of forward movement of the cars (201 to 206) (a direction indicated by either one of arrows (H1 and -H1)).
