Methodology of substantiation of innovative technologies of railway track design and maintenance

Background: The most important priority for ensuring the economic efficiency of transport is to increase revenue from freight and passenger transportation, as well as reduce one-time and operating costs during the life cycle of railway infrastructure development projects. The study reveals the expediency of using innovative technologies for the design and maintenance of railway tracks to ensure various effects when performing rail transportation. Aim. Development of the basis for the application of innovative technologies for the construction and maintenance of railway tracks, ensuring high operational performance and reducing costs associated with the creation and operation of transport infrastructure. Materials and methods. The research methodology is based on the theory of economic efficiency, which makes it possible to evaluate both individual effects from the use of innovative railway track construction technologies and the integral effect during the project life cycle. Results. Development of a methodology for determining the effects of the use of innovative railway track design technologies during the life cycle of the project. Conclusion. The developed methodology has practical application in substantiating the use of innovative technologies for the design and maintenance of railway tracks during construction, reconstruction, capital and routine repairs.
