Research conclusions: According to the characteristic of the Chinese high-speed railway , the real-time requirement of the disasters information is very important to reduce railway loss in disaster. So Chinese prevention system should be established on the basis of Chinese railway traffic characteristics so as to define the monitored information on disaster and upon which the train must be directly controlled.
