Systems and subsystems of track, control and management of high-speed railway

Abstract

Abstract The article discusses the following issues: according to the current level of development and equipment of the existing network of railways in Ukraine, it is necessary to state the determination of the gauge of the high-speed line; the main characteristics of the highspeed rail system and the general requirements for laying the line; track systems and subsystems, as well as including their movement and control on free terrain, ensuring the safety of operation and transportation of passengers with the declared conditions of comfort and speed; the distance between the centres of the tracks increases in proportion to the speed of movement of passenger flows, which requires additional arrangement of the roadbed, taking into account the radii of the curves, the elevation of the outer rail, the angle of descent and ascent of the track, the equivalent taper, the slope of the rail, the profile of the rail head, such as rail and sleepers; lateral and vertical forces acting on the track. In order to ensure traffic safety at the maximum permissible speeds, it is necessary that the indicated vertical and lateral forces (static and dynamic) meet the requirements, which in turn depend on the above factors.
