Abstract
Strong wind is really a problem that is directly relevant to a safe operation of trains. There have been about thirty wind-induced accidents of train/vehicles since transport service was started in 1872. The regulation rule for train operation was revised frequently after the accidents. Then in strong wind areas hardware measures like wind fences have been installed on railway lines to improve the safety of train operation after the Amarube Bridge accident in 1986. This report presents the regulation of train operation and measures against strong winds in railway lines.
