The tariff policy of freight transportation in the context of railway transformation in Uzbekistan

This abstract examines the tariff policy of freight transportation in the context of railway transformation in Uzbekistan. Given the changes taking place in the country's railway sector, particular attention is given to analyzing and assessing the impact of transformation on freight tariffs and transportation conditions. The study explores factors influencing tariff formation, such as changes in railway company structure, infrastructure modernization, reforms in government policy, and private investment attraction. The importance of establishing optimal tariffs and creating competitive conditions for freight transportation in times of transformation is emphasized, and recommendations are provided for improving the tariff policy considering the changes in Uzbekistan's railway sector. This study aims to provide useful information and practical recommendations for railway companies, government authorities, and stakeholders to facilitate the development of an effective tariff policy and contribute to the sustainable development of railway transportation in Uzbekistan

Calculation of the speed of movement of the car along the entire length of the path profile with different inclines of the sorting slide

In the article, a formula derived on the basis of the kinetic energy change theorem for a non-free material point in a finite form is used to calculate the speed of movement of the car on various sections of the sorting slide. Examples of calculations show that in the intermediate section of the sorting slide to the dividing switch, the relative calculation error is 10.3%, in the section of the switching zone of the sorting slide of the second dividing switch – δv6s2 ≈ 9.0 %, in the section of the first sorting path – δv7 ≈ 16.1%

Analysis of the movement of an empty railcar on the longitudinal profile of the sorting slide

The article uses analytical formulas derived from the application of the basic law of dynamics for non-ideal connections (the Dalembert principle), the calculation of the kinematic parameters of the rail carriage movement (acceleration, time, braking path) in the braking zone on the site of the first braking position of the sorting slide is performed. All over the world, it is becoming increasingly important to design and build modern sorting stations, as well as to choose the right height for sorting slides. The main function of the sorting slide at railway stations is the disbanding of trains, as well as the formation of new trains. Sorting will depend on how rationally the profile of the descending part of the slide is designed. Calculation of the height of the descending part of the slide and design work is carried out according to the existing method, according to which the movement of the railcar on the slope of the sorting slide, the speed is determined by the expression of the rate of fall of the railcar vertically, taking into account the inertia of the rotating masses. This, in turn, creates several problems. In developed countries, including the US, Germany, Sweden, China, India, and Russia much attention is paid to the development of methods, such as mechanization and automation of sorting ways of stations that affect haul transport and local rail network [1-7]

Optimization of transport flows of the grain storage

Ensuring uniform supply of wagons for loading and unloading of goods is one of the main tasks of the transport process. Existing methods for solving the issues of ensuring the rhythmicity of the supply of wagons for loading grain are not often allowed to identify the causes of the technological shortage of wagons. In this regard, within the framework of this work, the aim of the study is to increase the efficiency of the organization of providing grain storage with wagons using models
