Abstract
Modern tendencies in the market of transport services for passenger transportation are the relative reduction of the role of railways and the increase of the value of automobile and air transport. High-speed carriage can change the situation in its favor. To enter a high-speed traffic on Ukraine's railways, we need to take into account many different aspects. The article deals with the problem of increasing the quality of the current collection at high velocities by providing a rational aerodynamic characteristic of the collector of the electromagnetic composition. The problems of current collection at high speeds, the effect of counter propagating current on the current collector, and the methods for controlling the contact pressing of a current collector of an electric rolling stock are considered and analyzed. The research of the aerodynamic forces of the current collector using the wind tunnel is described and the most promising method for improving the current collection is given. To improve the efficiency of Ukrainian rail transport, it is desirable to solve the main issues that are posed today.
