Аннотация

This article analyzes the main types of wagons used in railway transport, their structure, and functional tasks. Each type of passenger and freight wagon is considered separately, and their operating principles and practical application areas are highlighted. The influence of modern technologies on the efficiency of wagons is also analyzed.

Rail transport occupies an important place in the national economy and is one of the most efficient and reliable means of transporting goods and passengers. Railway wagons are specially designed for the transportation of various types of goods and passengers, each of which performs itsown functional tasks. A wagon is a unit of railway rolling stock intended for the carriage of passengers or cargo. The modern wagon fleet is distinguished by the diversity of their types and structure. This stems from the need to meet various requirements in transportation: ensuring domestic comfort for passengers, maintaining the quality of perishable cargo, protecting fragile cargo from collisions, protecting some cargo from atmospheric effects, universality, maximum utilization of load, and others. Taking these factors into account, the complexity of the wagon structure is determined, which is equipped with high speed, the necessary level, low resistance, automatic seals, and automatic brakes during movement. Based on designation, technical characteristics, and place of use, wagons are divided into two main types: passenger and freight wagons. page2036 INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE ISSN:2692-5206,ImpactFactor:12,23 AmericanAcademicpublishers,volume05,issue05,2025 Journal: https://www.academicpublishers.org/journals/index.php/ijai Passenger wagons, as a rule, must meet the requirements of comfort and safety. These include General Wagons, Coupe Wagons, SV (luxury) Wagons, Platskart Wagons, Restaurant Wagons, and Special Passenger Wagons. Common wagons are the cheapest passenger cars and have a large capacity. They are often used on long-distance roads and local traffic. As an example, one can cite the wagons used fordomestic flights inUzbekistan. Coupe wagons are wagons with more comfortable conditions, with 4 beds in each compartment. They are usuallyintended forlong-distance travel. SV (luxury) wagons are wagons that provide a high level of personal comfort, with two beds and modern services. page2037 INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE ISSN:2692-5206,ImpactFactor:12,23 AmericanAcademicpublishers,volume05,issue05,2025 Journal: https://www.academicpublishers.org/journals/index.php/ijai Platskart wagons are open coupe-shaped sleeping cars that have a relatively low price andserve as publictransport. Restaurant wagons - provide passengers with the opportunity to dine on long journeys. They have akitchen and service staff. Special passenger wagons - for example, special wagons adapted for people with disabilities orequipped forofficial delegations. Freight wagons are designed totransport various goods andhave different designs. Platforms - used for transporting large and bulky cargo, including automobiles, agricultural machinery, and bulky containers. For example, container platforms are widely used ininternational cargo transportation. Tankers - used for transporting special liquids, such as petroleum products, chemicals, or food products. For example, there are special isothermal tanks for gas, liquid fuels, and dairy products. page2038 INTERNATIONAL JOURNAL OF ARTIFICIAL INTELLIGENCE ISSN:2692-5206,ImpactFactor:12,23 AmericanAcademicpublishers,volume05,issue05,2025 Journal: https://www.academicpublishers.org/journals/index.php/ijai Covered wagons are designed for transporting various types of dry cargo, such as food products, furniture, and industrial equipment. They have a closed structure to protect cargo from weather conditions, and their doors comply with safety requirements. For example, covered wagons are used fortransporting grain products. Open-top wagons are mainly used for transporting large-volume cargo such as coal, ore, and gravel. Their side walls are relatively low, facilitating loading and unloading. For example, coal extracted from mines or gravel for construction is delivered using thesewagons. Carriage wagons - used bylarge car manufacturers ordealerships for thedelivery ofcars. Forexample, cars produced by"Avtozavod" are transported inthese wagons. Special wagons are designed for the transportation of special cargo and are divided into thefollowing types: Refrigerated wagons are used for transporting meat, dairy products, and other perishable food products. For example, seafood or frozen vegetables are delivered in thesewagons. Temperature-retaining wagons are designed for transporti
