Lateral force on trains due to local acceleration of the wind is investigated by using the three-dimensional vortex method. Local acceleration of the wind was simulated by a vortex rinrg. In case of blowing down, it is sound that the numerical results of lateral force coefficient becomes peaks when the group of vortex sticks whose direction of vorticity is the same as the vorticity of the separetion region behind the train are taken in the separation region. On the other hand, in case of blowing up, it is found that the effect of the vortex ring is small.
