On the basis of theoretical prerequisites and experimental studies, to substantiate the choice of factors that determine the formation of a dynamic load on the track from modern rolling stock for high-speed and high-speed traffic. As a result, a method for determining the vertical design force acting from the wheel on the rail is given. Methodology. Fundamental structural changes in high-speed and high-speed trains, a significant increase in the speed of movement lead to the need to revise the methods for calculating the effect of rolling stock on the railway track, the ratio of standard deviations of various dynamic forces, and assessing the influence of various factors for different speeds of movement. The paper also investigates the change in the dynamic load based on the results of experimental measurements. Results. The dependences of the average and calculated vertical forces on the speed of movement for modern passenger trains. Using factorial dispersion analysis, numerical characteristics of the impact of various factors on the value of the effect of the vertical force of the wheel on the rail are obtained. The degree of influence of various factors on the formation of the value of this force is established.
