GENERAL PRINCIPLES OF SIGNALLING SYSTEMS FOR HIGH SPEED LINES AROUND THE WORLD

The article deals with the general approaches for construction and today’s trends in development of train control systems for high-speed rail lines, taking into account the data transmission principles, such as cable loops, track circuits and radio, as well as the general architecture of train control systems for high-speed rail lines. The paper shows that advanced train control systems for high-speed rail lines feature significant adaptation and integration of legacy command and control systems, as well as hybridization of control loops providing for the redundancy of radio control loop with coded track circuits to increase the safety and resilience of the systems.
