Numerical simulation has been made to predict the aerodynamic loads on a passenger car model. The relation between aerodynamic coefficients and yaw angles is calculated. At the same time a math model of train's overturning is built based on moment balance, and the relationship among the highest safe running speed of train and wind speed and direction is studied. At last train speed regulation is put forward based on the side wind speed and wind direction. The results show that speed regulation based on wind speed and direction will greatly improve the transportation capability of the railway line.
