Summary. Nowadays, the Republic of Kazakhstan is dynamically forming up its transit policy, improving its directions and the development of new vectors. This article looks into the development of the transit and transport potential of the Republic of Kazakhstan. It presents the main conclusions on the development of a feasibility study for the construction of a logistics terminal in the seaport of Lianyungang (China) as one of the directions of building transit policy, improving its direction and the formation of new vectors. The urgency of building a logistics terminal is conditioned by the necessity for national interests and further expansion of political and economic advantages of Kazakhstan.
КЛЮЧЕВЫЕ ФАКТОРЫ РАЗВИТИЯ ТРАНЗИТНО-ТРАНСПОРТНОГО ПОТЕНЦИАЛА КАЗАХСТАНААннотация. Сегодня Республика Казахстан находится в процессе активного выстраивания своей транзитной политики, совершенствования ее направлений и формирования новых векторов. В статье рассматриваются вопросы развития транзитно-транспортного потенциала Республики Казахстан. Представлены основные выводы по разработке ТЭО строительства логистического терминала в морском порту Ляньюньган (КНР) как одного из направлений выстраивания транзитной политики, совершенствования ее направлений и формирования новых векторов. Актуальность строительства логистического терминала продиктована необходимостью реализации национальных интересов и дальнейшего наращивания политических и экономических преимуществ Казахстана.
The primary specific resistance to the movement of freight wagons is a key parameter for normalizing the time and energy consumption of trains. Although the “Rules of Traction Calculations” calls for dividing wagons into six groups when calculating this resistance, in practice (using the traditional method), appropriate regulations are developed based on the separation of train wagons into two groups (4th and 8th lips). One of the main reasons for this is the inability to account for the unique features of each wagon in a given train. To address this issue, a program was developed for determining the necessary parameters of wagons for traction calculations based on their identification numbers. This software can be accessed through the website https://trainlocomotive.netlife.app/. Using this program, a method for calculating the primary specific resistance to the movement of freight wagons has been developed. Field sheets of freight trains moving through the Uzbekistan Temir Yullari railway station were analyzed. As a result, it was discovered that nearly half of the freight train composition consists of empty wagons, while the proportion of loaded gondola cars and tanks is 23%. The primary specific resistance to the movement of wagons in such a mixed composition is calculated using both traditional and developed methods. The impact of the primary specific resistance on the energy costs of maintaining the train is evaluated. As a result, the feasibility of utilizing the developed method for normalizing electricity consumption based on traction calculations is demonstrated.
An algorithm for simulating the number and order of cars in a train arriving at an access track.
The paper presents an algorithm for randomly generating the characteristics of trains arriving at the access road. Trains are characterized by the following parameters: the number of uncoupling cars arriving at the internal stations of the access track, the number of cars in each uncoupling, the order of the uncoupling in the train. The number of detachments is formed randomly in the range from one to the value of the total number of internal stations of the access road. The number of cars in each uncoupling is formed randomly from zero to one-third of the size of the train composition. Moreover, the proportionality of the volumes of car traffic going to each station is observed. The number of options for the location of detachments (permutations) is determined by the factorial of the number of stations. The number of the permutation variant is randomly selected.
