In this paper, the effects of rail vibrations transferred from the ground to the building in the vicinity of the rail are studied. The additional forces mostly produced in the contact area of the wheel and structure’s rail influence on the building in the vicinity through the soil underneath. The building is a concrete chamber located between 2 high speed railroadand in 2 meters distance from them. The Ansys software was used which can model the train forces, soil, rail and building’s components. One of the ISO 14837-1 curves was used as a raw curve of train vibrations’ effect and was made ready to enter in the software by mathematical transformations. The results of the software model have been studied in case the vibration frequency received by the building is equal to one of the effective natural frequencies of the building, which leads to damage to the joinery of the building (if the building is old or historical, it will overturn). By using damping layers in the building, the effect of train vibrations on the building adjacent to the rails is greatly reduced, and with this solution, damage is not caused even in the joinery of the building. The damping layers are made of rubber and polyurethane, which is produced by the German company "BSW". Another way to reduce the resonant effect is to increase the damping of the structure in different ways.
