The kinetic energy of cuts changes under the influence of natural interactions and deliberate human actions. Accelerating and braking a cut causes changes in its dynamic state. The efficiency of speed regulation depends on the accuracy of forecasting changes in the dynamic state of the cut. A factor disrupting the regulation process is operator interference in the system’s operation. New, fully automated speed regulation systems should enable a quasi-continuous assessment of the dynamic state of cuts and effective energy absorption, as well as eliminate human participation in the implementation of the regulation process.One of the essential phases of train processing carried out at a marshalling or shunting yard is the process of shunting wagons. Depending on the station’s equipment, shunting can be carried out in various ways. At stations equipped with marshalling humps, the cut moves as a result of the conversion of potential energy into kinetic energy. For the safe movement of the cut to its destination on the classification track, it is necessary to control and appropriately regulate its speed. Automatic speed regulation systems are used for this purpose, which include braking devices that reduce the kinetic energy of rolling wagons. (…)
