West Japan Railway Company continuously conducts research and development for further safety of the car from various aspects and has developed the passengers' fall from platform prevention equipment at the coupling section between head cars as one of the valuable result. Already the anti-falling safety barriers at the coupling section of intermediate cars had been equipped, but there was no such measure between head cars coupling section. Just simply attached side cover in front of the head car may prevent driver's visibility and capture strong wind influence that will cause the head car specific technical problems. But there was the passenger falling down accident between head cars coupling section. It strongly promoted the development of countermeasure preventing such accident for further safety improvement. At the developing stage, we analyzed the passengers falling process from the platform as in three phases which are "precaution against falling", "prevention against falling" and "countermeasure at falling" As the result, we decided to introduce on the service cars by developing the "falling prevent sound alarm system" as the precaution meaning and the "falling accident prevention equipment" as the falling prevention measure. This paper will introduce the developing process of the passengers falling down preventing measures at the between head cars coupling section.
