    The Advisability of Using Dual Gauge for Expansion of the International Traffic
    (Printing House “Technologija”, Kaunas, Lithuania, 2020) Kurhan, Mykola ; Kurhan, Dmytro ; Husak, Marina ; Hmelevska, Nelya
    ENG: The possibilities of railway transport for the organization of transportation between the countries are not used to the full extent, since there are a number of technical reasons. The usage of dual gauge (1435/1520 mm) is one of the solutions. As an example of using dual gauge is the international project "Rail Baltica", Lviv railway and etc.

    Impact of The Variable Stiffness Section on The Conditions of Track and Rolling Stock Interaction
    (IOP Publishing Ltd., 2020) Kurhan, Dmytro ; Kurhan, Mykola ; Husak, Marina
    ENG: Railway track stiffness is one of the main parameters that determine the track and rolling stock interaction. The inelasticity of the rail base may occur for two reasons: either as a consequence of the deteriorated condition of a track or due to the structural features of a section. As a rule, areas before bridges or tunnels are treated. Today, there are several options for relevant design solutions. The main purpose of this work is to determine the characteristics of a "railway track" object with which it can be represented in the rolling stock models in the simplest way possible but adequate for sections of transient stiffness. The railway track is introduced into the rolling stock model as a sequence of elements with which the wheels of the rolling stock interact. It is assumed that a single element in its characteristics must be equivalent to the track response when passing the wheel from one inter-sleeper section to the next one, that is, to reproduce a sequence that is cyclically repeated. Such a track element will be characterized by reduced mass, stiffness and dissipation factor.
