Railway accidents and accidents caused by derailment of railway rolling stock, always and everywhere in the world, account for the highest share of all rail incidents. The experiences, research and scientific contributions of our country, respectively, the Transport Research Institute of BDZ, to avoid or reduce the cases of derailment of the railway rolling stock relate primarily to operating speeds to the maximum permissible. The experience of the BDZ and the tests carried out by the Scientific Research Institute for Transport (SRIT) show that some of the railway vehicles are at risk of derailment at operating speeds due to particularly intense horizontal oscillations normally obtained in resonant mode. Objects of the present study are mainly wagons prototypes in the first embodiment, such as: two-axle freight wagons of different base types from 4 m to 6 m, four-axle wagon for gauge 760 mm, open-cargo freight wagon type Eads, open rail wagon for track gauge 760 mm and specialized hopper Coal type Falns. Indicate directions for creating new, more sophisticated constructions and technologies to increase security against derailment of rolling stock. The new constructions cover mainly bogies and the frame of the wagon and consist of the modernization of the same in recent decades and the introduction of new ments for their construction and repair.
