Research of Typical Schemes of Conversion of Stations for Speed Passenger Traffic in Comparison with the Variant of the Bypass Construction

The development of railway high-speed passenger traffic in Russia under conditions, when the construction of a high-speed line is still at the stage of justification, is an actual and rather difficult task, requiring a thorough feasibility study. This task is sometimes even more complicated than the construction of a new line for the implementation of high-speed traffic, as it requires taking into account a large number of factors, for example, procedure of construction work at a large number of separate points with track development, even small ones, of intermediate stations and divert stations. As a suggestion, the authors review, as an alternative to reconstructive measures, the principle possibility of using detours for the passage of high-speed passenger trains, which in practice are often used for transit traffic organization, more often freight traffic, less frequently - passenger traffic. Previously proposed typical schemes of the conversion of intermediate separate points with track development for high-speed passenger traffic are being analyzed; conclusions about the possibility of using bypass lines instead of reconstruction are being made. The article may be useful to specialists, who make researches in the sphere of high-speed passenger traffic organization from the point of view of preparation of existing highways in general, and railway stations in particular.
