Introduction One of the most important tasks of railway transport is ensuring a stable and uninterrupted transportation process. As it is stated by Čižiūnienė et al. (2024) and Koshel et al (2023), in modern operating conditions, this task is not only important from an economic point of view, but also from a strategic point of view. Gerlici et al. (2023) described that an open wagon is the most common type of wagon in operation for a long time. This wagon type is usually used for the transportation of goods that do not require protection from atmospheric influences. At the same time, open wagons are also used for the transportation of goods that require shelter. For this purpose, this wagon is equipped with a removable roof or awning. It is important to note that open wagons are one of the most damaged types of wagons. At the same time, a significant amount of damage occurs to the body wall shells. As it is described by Dižo et al. (2015), Ézsiás et al (2024), Fischer (2025) and Mikhailov Abstract The article highlights the results of determining the feasibility of using corrugated sheets as a wall covering for an universal open wagon body. Such a solution will help to reduce the damage of the wagon body walls under operating conditions. Possible options for their implementation were considered to determine the most rational configuration of the corrugations. It is proposed to use a rectangular configuration of the corrugations of wagon body walls, because this technical solution has the greatest moment of resistance of its cross section. The thickness of the wall sheet is determined by the Bubnov-Galyorkin method. Since it will be formed by rectangular corrugations, the thickness of the sheet was δ = 1.8 mm. A finite element analysis of the open wagon body walls formed by rectangular corrugations was performed. It was established that, considering the proposed solution, the stress in the side wall is lower by 7% than in the typical version of the side wall. The conducted research will contribute to develop and to improve the technical and economic performance of wagons, as well as to improve their strength under operational load conditions.
