Development of rail transportation with rely on increasing speed and axle loadin recent years has been encountered with significant progresses. If the induced noise and vibration due to rail way system wasn’t controlled, it would effect significantly on the residential areas and other sensitive places.Although in the technical literature the inserting the in filled concrete trenches on both sides of the rail lines has introduced as one of the strategies to reduce ground born vibration but the avalibale studies shows that the effect of trench shape on the vibration reduction hasn’t been investigated. So in the present study three types of rectangular shape, v-shape and step-shape in-filled concrete trenches have been compared in terms of efficiency with equal areas
