The article is devoted to the study of dynamic interaction of rail track and freight wagons under increased axial load. In conditions of increasing the freight traffic volumes and axial loads, the importance of accurate understanding of the mechanisms affecting the wear of rail track elements becomes especially important. In this paper the authors have carried out experimental research and comparative analysis of freight wagon trolleys of different models. As a result of dynamic tests of the freight wagon trolleys, the necessary parameters of dynamic qualities of different models of wagons and their optimal values of axial loads of freight wagons are obtained. The necessity of improving the current design of wagon trolleys and reinforcing the design of railway track with the use of R65 type rails and reinforced concrete sleepers is substantiated. According to the data of trolley design comparison of different models, the bending moment and maximum load indices are established.
