FEATURES OF INCREASING TRAFFIC SAFETY AND RELIABILITY OF USING GAS-TURBINE TRAINS IN HIGH-SPEED RAILWAYS

Background. The article considers the issues of increasing traffic safety and reliability of technical means of gas turbine trains (systems) in high-speed railways (HSR). Materials and methods. Complex indicators in the form of: probability of failure-free operation of technical means, availability factor, as well as time between failures (RAMS) and features of using gas turbine traction as a power plant (system element) of gas turbine rolling stock during operation on high-speed HSR are suitable for assessing and managing train traffic safety. To analyze the reliability and safety of gas-turbine motor-car trains in comparison with trains on diesel power plants and electric trains, magnetic levitation, etc., adaptive methods of comparative analysis of information, ranking are used. Results and conclusions. It is shown that the introduction of gas-turbine traction will reduce investment and operating costs of high-speed railways while maintaining the dynamic characteristics of trains, including the braking system.
