It is inevitable to take into account some measures to alleviate the influence of the train-induced vibration for utilizing buildings over a railway with quiet indoor environments. In order to develop a floating railway structure some experiments were carried out laying a short railway with an actual carriage. The effect on vibration reduction with several devices altering spring constant was quantitatively examined. It was found that this floating structure is effective on reducing the train-induced vibration. Also, it was discovered that the first natural frequency of the vibration system for train-running can be predicted by the single-degree-of-freedom system in consideration of total mass below the axle spring.
