Abstract
Development of proposals for adapting the existing methodology for calculating the available throughput to the operating conditions of the railways of Uzbekistan, taking into account the factors that ensure traffic safety when passing high-speed passenger trains. Methods: Grapho-analytical approaches and a comparative analysis method were used to determine the throughput of railway lines with mixed train traffic. Results: The main factors influencing the capacity of lines, advantages and disadvantages for each existing method for determining the capacity of railway lines are given. To assess the quality of transportation processes on railway lines, experimental train schedules were constructed. Based on the analysis of their indicators, a formula was proposed for calculating the throughput on double-track lines when passing high-speed passenger trains. Practical significance: The application of the proposed methodology improves the calculations of the performance indicators of sections with an unparalleled train schedule.
Highlights
The technical capability of railways to ensure the transportation of passengers and goods is determined by the throughput of the main devices and structures [1]
With insufficient development of transport infrastructure on the railway line, mixed train traffic is organized, which is the passage of high-speed, high-speed passenger and freight trains on one track
According to [1], to calculate the maximum possible number of freight trains, set mass and length that can be passed along the line per day with a non-parallel traffic schedule, the following analytical expression is recommended: Nmгрax
Summary
The technical capability of railways to ensure the transportation of passengers and goods is determined by the throughput of the main devices and structures [1] This characteristic makes it possible to determine the possibility of developing the existing and future traffic volumes under various scenarios of the development of the economy of Uzbekistan. With insufficient development of transport infrastructure on the railway line, mixed train traffic is organized, which is the passage of high-speed, high-speed passenger and freight trains on one track. This organization is the most widespread in the world and the most complex. Special attention is paid to the technological issues of operating railway sections with mixed traffic
