Abstract: The characteristics of railway flood disasters in China are analyzed, and the statistical models of the whole country and four main railway bureaus (Chengdu, Zhengzhou, Harbin and Shenyang) are established, respectively by using line break time and frequency from 1980 to 1995 and total days of heavy rain and torrential rain at the same periods. All these efforts would lay the base for assessing the impacts of abnormal climate quantitatively on railway transportation.
