To analyze the results of study of dynamic parameters of the tank-car model 15-1900 and gondola car model 12-1905, equipped with the bogies model 18-1711 with axle loading of 25 ton and unified according to major parts and joints with the cars of previous generation. According to results of the study to conclude about the possibility of using bogies model 18-1711 as the running parts of the freight rolling stock of the new generation of 1520 mm track with increased axle loading. Methodology. The dynamic performance of the rolling stock running parts directly affects the safety of railway traffic. Experimental studies of the car dynamic qualities are an important step in the modernization of existing bogie constructions and in the creation of the new ones. These tests allow one to confirm the results of theoretical studies and to check the correctness of the constructive solutions. Findings. Basic results of dynamic studies are presented as the graphs of dynamic performance dependencies on the motion speed of the experimental train. Results show that the freight cars on the bogies model 18-1711 have satisfactory dynamic properties meeting current regulatory requirements. Originality. The dynamic characteristics of freight cars on bogies model 18-1711, which give a complete view of the car loading allow us to estimate the dependency of the car dynamic performance on the bogie design parameters. Practical value. The bogie model 18-1711 with axle loading 25 ton can be used as a freight car undercarriages of the new generation of 1520 mm track.
