Conceptual approaches to the selection of the route of high-speed highways. Determined rationality of network performance evaluation for high-speed trains. Obtained results of the most characteristic of roadbed, bridges and track structure in the areas of high-speed traffic. Proposed design for the Ukrainian railways. Obtained results of the interaction of the track with roadbed based on overseas experience. The recommendations with respect to the stabilization of the roadbed and reduce strains in different operating conditions. The methods of evaluating the reliability of the roadbed, bridges and track structures. Submitted way engineering strength calculations, the results of which established the possibility of laying of jointless track for different operating conditions with the introduction of high-speed trains. The necessity of creating a regulatory framework to ensure performance reliability of the path. Development of technical and economic approaches to the establishment of optimal directions of highways in Ukraine. Proposed the construction of the permanent way, bridges and roadbed conditions for high-speed traffic. The mathematical model of the power dynamic between rail track and rolling stock, as well as the model of accumulation of deformation of subgrade. We propose a dynamic calculation spans with a variation of the speed of passage of rolling stock. On the basis of mathematical models developed engineering methods of calculation of strength, stability and durability of elements of railway track and rolling stock. The results used to justify the permissible speed of trains, as well as the development of regulations for the implementation of high-speed movement in Ukraine. Established recommendations on the choice of parameters railway track and proposed the standards of maintenance lines in areas of high-speed trains. Product Description popup.authors Байдак С.Ю.
