Trial towards simple and informative wayside equipment in East Japan Railway


  • Expectations to DAS
  • Informative one optic fibre cable: Experiences toward train detection and disaster prevention
  • Future prospects of research regarding DAS


Introduction to expectations of the DAS system and the latest research. JRE are developing the applications with the expectation that the DAS can be a simple and informative wayside equipment. The detection of natural phenomena is already effective and we examined the method of train detection for safety application. Although the research phase is preliminary, we confirm that the DAS system can change wayside equipment dramatically.
