Recently, vibrations occurring in the railway track and its neighbouring structures due to the running trains are attracting public attention as a main problem of pollution. In this study, magnitudes of vibrations generated in the infrastructure are compared by changing the material characteristics of each components of the track, and appropriate track characteristics for anti-vibration are suggested. Track and infrastructure are modelled as a multi-degree-of-freedom lumped mass system by using the effective lengths, and the unsprung mass of the wheel is assumed to contact with the rail through the Hertzian spring. Then, impact vibration response by the wheel dropping from certain height and the frequency response due to the periodic loading are obtained. From this study, it has been found that the proper way to reduce magnitude of vibration transmitted to the infrastructure is to increase masses of the track components and / or to make the fasteners and the mats more flexible. However, it seems that there should be the mechanical proof for their allowable limits considering running safety of the train.
