A properly designed and manufactured vibration isolation system of railroads and civil engineering structures has a decisive influence on the reduction of vibrations caused by crossing trains, trams and subway transferred to residential buildings This article presents an overview of current vibration isolation systems of railroads and civil engineering structures. Based on the effectiveness of the protection of residential and industrial buildings from vibrations the ranking of vibration isolation systems was proposed. The article also attempts to assess the effectiveness of vibration isolation systems currently used in rail trails. For this purpose, a discrete-continuous model of vibration isolation system of railway and tramway rails was build. For this model, dynamic analysis was carried out. Performed analysis allowed determining range of the natural frequency of vibration isolation system. The results of dynamic analysis allow pitching shift the natural frequency of the system under consideration from the frequency of excitation, which in turn is a fundamental condition for the proper operation of the vibration isolation. As part of work on a physical model of vibration isolation system there was also developed one-level crossings of roads and railroads. The work was carried out in a research project 4875/B/TO2/2010/38 financed by Ministry of Science and Higher Education.
