TL;DR: In this article, the influence of longitudinal quasistatic tensile and compressive forces in gondola cars arising at stationary and transient modes of train movement on their main dynamic indicators and interaction indicators of rolling stock with a rail track, taking into account the possibility of speed increasing.

TL;DR: The practical significance of the obtained results is the use of such a calculation method that does not require significant time for its implementation and can be used as a subsystem of the on-board train control system capable of performing calculations taking into account changes in the current train situation.

TL;DR: In this article, the authors present the procedure used for establishing the cause of the wagon derailment, which is based on the mathematical models of longitudinal oscillations of a train and the spatial vibrations of wagons, in particular of tank wagons.

TL;DR: The authors proposed a method of determining the reliability indicators and solving scientific and applied problem of calculating the elements of freight cars, taking into account the operation features and the loading mode impact, which allows determining their durability at the design stage.

TL;DR: In this article, the authors clarified the existing method of determining the factor of stability from the tire longitudinal forces to ensure the sustainability of cars with increasing speeds of the rolling stock, and developed proposals for the refinement of existing methods for determining stability coefficient of longitudinal forces squeezing cars in a train, can reduce the number of retirements cars derailed by taking into account in the calculation and design of important parameters and characteristics that increase their stability in the rail track especially with increasing speed of freight traffic.
