Abstract—This article aims to assess the dynamic loads acting on railway track structures during the operation of open wagons in a degraded technical condition, particularly under increased axle load conditions. The study investigates the interaction characteristics between the open wagon and the superstructure of the railway track, focusing on how wear of components and assemblies in the bogie system influences the magnitude and nature of load transmission. A combined experimental and computational analysis of open wagon dynamics was conducted, considering both loaded and empty operating states, as well as varying levels of technical degradation. The findings allow for the identification of critical parameters that influence operational safety and track degradation. Additionally, the study offers recommendations concerning the permissible range of stability margin coefficients and the operating conditions for worn rolling stock under horizontal and vertical loading scenarios.

Keywords—dynamic loads, railway track, open wagon, horizontal and vertical forces, simulation of motion dynamics, carriage wear
