Objective: To determine the main approaches to safety management of high-speed railway transport on the basis of modern international and domestic practices in the specified sphere. Methods: Analysis methods of security risks on railway transport were considered in accordance with modern international standards of management of interconnected indices’ complex, which include reliability, availability, maintainability and safety and cost (Life Cycle Cost – LCC) at all stages of transportation systems’ life cycle: EN 50126 (IEC 62278), EN 50128 (IEC 62279), EN 50129 (IEC 62425) and IEC 60300-3-3. Results: The main approaches to safety measures of high-speed railway lines (VSM) were detected. The former involve using a lifecycle concept of engineering systems and facilities, management methodology of RAMS/LCC interconnected indices’ complex at all stages of a life cycle, wide application of the process approach and the tools of quality and safety management systems, development and implementation of technological maturity assessment methodology for security management activities, as well as object-oriented and coherent improvement of regulatory base, the systems of administrative and control and permission authorities, technical and technological development, management of external, inland and allocated risks under market relations. Practical importance: The examined approaches of VSM safety control make it possible to obtain a priori estimates of safety control processes and thus determine the achieved level of safety together with the levels of technological maturity of railway organizations’ processes.

The Beijing-Shanghai High-Speed Railway (HSR) is one of the most important railways in China, but it also has impacts on the economy and the environment while creating social benefits. This paper uses a life cycle assessment (LCA) method and a life cycle cost (LCC) analysis method to summarize the energy consumption, carbon emissions and costs of the Beijing-Shanghai HSR from the perspective of life cycle, and proposes some corresponding suggestions based on the results. The research objective of this paper is to analyse the carbon emissions, energy consumption, and costs of the rail system which includes the structure of the track and earthwork of the Beijing-Shanghai HSR during four stages: conception stage, construction stage, operation and maintenance stage, and disposal stage. It is concluded that the majority of the carbon emissions and energy consumption of the entire rail system are from the construction stage, accounting for 64.86% and 54.31% respectively. It is followed by the operation and maintenance stage with 31.60% and 35.32% respectively. In contrast, the amount of carbon emissions and energy consumption from the conception stage is too small to be considered. Furthermore, cement is the major contributor to the carbon emissions and energy consumption during the construction stage. As for the cost, the construction stage spends the largest amount of money (US$4614.00 million), followed by the operation and maintenance stage (US$910.61 million). Improving production technologies and choosing construction machinery are proposed to reduce the cost and protect the environment.
