The environmental noise and the wear of rail occur, because the railways run while rolling wheel on the rail. Recently, the railway truck without the sleeper and the ballast is being used. The occurrences of the rolling noise and the wear of rail may be different from the previous generation. Therefore, in this study, the effect of the sleeper and the ballast were examined through experiments and analyses, when a wheel runs on the rail in passing through the connection point. As a result, the damping ratio of the truck with sleeper is higher than that without sleeper. And it was shown that there was a setting condition of ballast for the increase of damping ratio. Furthermore, it was shown that the natural frequency of rail was changed by the displacement of wheel on the rail.
