Study of Bypasses for High-speed Passenger Trains, as an Alternative to the Reconstruction of Railway Stations

Nowadays, in order to organize the movement of passenger trains with speeds up to 200 km/h, it is necessary to reconstruct existing highways, which requires the need, in addition to performing a huge amount of work, to do it “under wheels”, i.e. in conditions of continuous movement, when it is often impossible to take trains to other routes (parallel passages), due to the lack of the last ones. As an alternative, the authors propose to consider the principal possibility of using bypasses for the passage of high-speed passenger trains, which in practice are often used for the organization of transit freight traffic, both individual railway stations and railway junctions in general. This allows not only to remove obstacles (“barrier places”) on the way of train traffic, but also to “unload” the existing infrastructure of railway stations and nodes. For this purpose, at the first stage, the factors that can affect the feasibility of using bypasses to perform such a task as the organization of high-speed passenger train passes were considered. The article can be useful for specialists, researchers who are engaged in the solution of issues on the organization of high-speed passenger traffic in terms of the preparation of existing highways in general, and railway stations in particular.
