Wind-Induced Accidents of Train/Vehicles and Their Measures in Japan

Since train vehicle accidents caused by strong winds sometimes occur in Japan, Japan railway companies requested the Railway Technical Research Institute to promote research and development of preventive measures. To respond to this request, we have investigated aerodynamic forces acting on train vehicles and characteristics of strong winds and proposed several software and hardware preventive measures. This report presents the results of our investigation and the measures adopted in Japan Railway lines.
