ARTICLE ANNOTATION

quote
This article describes in detail the technical parameters of two-track sections with mixed traffic of high-speed passenger and freight trains at JSC “Uzbekistan Railways”. In addition, the maximum movement speeds of freight and high speed passenger trains on existing sections in each section, the results of timing observation of train timetables. Also, the kinematic parameters of trains in the process of mutual crossing are explained in detail. In this context, recommendations were given on how to eliminate lost time spent in the process of crossing trains at the sections. It is known that in the process of dispatching high-speed passenger trains on two-track sections with mixed traffic, the freight trains that need to be sent from the station stand still for a long time during the observations. there is a need to calculate all kinematic indicators. From this point of view, the mathematical description of the time lost during the intersection of high-speed passenger trains and the process of replacing it in the most optimal sections is explained in detail. In short, there is a possibility of safe crossing of trains based on the set speed of high-speed passenger and freight trains in JSC “Uzbekistan Railways”. The development of mathematical models for calculating these indicators and the regulation of the train movement schedule during the modeling of this process, as well as preventing freight trains from standing idly in the sections, creates the possibility of effective use of the train carrying capacity of the sections.
