Various parts and equipment are attached to the bogie of the railway vehicle. These parts are subjected large vibration during running. The accident rarely happens that the parts are fall by this vibration. Therefore, the vibration prediction technique of the bogie is needed. The authors have proposed a method of predicting the vibration at the evaluation points in the bogie from the impact test carried out with the vehicle stationary. It was confirmed that the proposed method could predict the vibration during the running on the commercial line up to 100km/h. In the previous research, only one vehicle was examined. In this paper, the results of applying to the other two vehicles were shown. As the result, the proposed method could be applied to two vehicles. However, it was shown that the best condition of the impact test was different according to the type of vehicle or the evaluation point. Therefore, the running test results in the depot were used as a new excitation method. The accuracies of the prediction were improved by using the results of running test in the depot. However, it was needed that the multiple coherences between the vertical acceleration of the axle boxes and evaluation point were sufficiently large.
