In this paper, it is aimed to model aerodynamic force that acts on the train running at high speed in tunnel sections. An analytical model of the aerodynamic force is developed from the pressure data measured on car-body sides of a test train running at the maximum operation speed. The running simulation of 8-car train subjected to the modelled aerodynamic force shows following results. The simulated car-body vibration corresponds to the practical ones in quality and also in quantity, for the cars connected in the rear of a train. The separation of airflow at the back end of train increases the yawing vibration of the tail car while it gives little effect on the car-body vibration of adjoining car. And, the effect of moving speed of aerodynamic force on the car-body vibration is made clear, that is the simulation with the assumption that the aerodynamic force does not move can enlarge the car-body vibration most remarkably.
