“…During movement along the section, this train collects unloaded and loaded wagons at intermediate stations and replaces them with wagons intended for loading and unloading operations at these stations [5]. The following operations are performed with wagons brought to intermediate stations on a local train: separation from the train, transfer to the freight front for loading and unloading, transfer from one loading-unloading place to another, assembly of loadedunloading wagons and connecting to the train [3,[6][7][8].…”

In the mentioned article, an analysis was conducted on the delay in providing services to local wagons due to the distance of up to 200 km between the sections located in the “UTY” joint-stock company. In this regard, works to improve the schedule of local trains have been carried out by extending the distance between two technical stations to 600-800 km. As a result of analyzing the options for transporting local wagons to technical stations in this article, movement schemes for local trains have been developed. The proposed schemes specify the movement of local trains from the initial station to the final station within the sections, as well as determining the movement from the initial station to halfway through the section. Through these schemes, operations carried out at intermediate and freight stations between two section stations in a mathematical manner have been investigated. These operations include operations such as coupling, uncoupling, and providing technical and cargo services to the wagons within the movement composition. In providing services to local trains on the section, two options were analyzed to obtain results: with the help of the second scheme we developed, during the movement of each train within the section, a possibility of saving 16 minutes of time was created.

At present, in the existing methods for determining the height of a hump, the height is calculated based on the most difficult conditions - winter temperature and head wind, and a four-axle empty covered wagon is selected for a poor runner. Based on the basic law of dynamics (D’Alembert’s principle) as applied to weak links and the use of analytical formulas in the article, the calculation of the kinematic parameters of the movement of cars in the braking zone of the section of the first braking position of the hump is carried out. A sorting hump 3.08 m high is considered, for a four-axle empty covered wagon the winter temperature is -100, the headwind speed is 5 m/s m. When calculating the height of the marshalling yard, it is necessary to take the technical characteristics of a four-axle empty gondola car as a poor runner, since the headwind also acts inside the gondola car and prevents the car from rolling down the hill. It is recommended to study the effect of a headwind on a four-axle empty gondola car.
