Abstract: The object of this study is the processes of perception and redistribution of longitudinal loads in the structure of a tank container placed on a flat wagon during a shunting collision. In this paper, the task was solved to ensure the strength of the tank container during rail transportation. In order to identify the stress concentration in the tank container, mathematical modeling of its longitudinal load under the condition of being placed on a flat wagon during a shunting collision was carried out. The resulting accelerations were taken into account when calculating the strength of the tank container. It was established that the maximum stresses occur in the zone of interaction of the paw with the vertical rack and amount to 938.2 MPa, which is significantly higher than the allowable ones. It has been proposed to improve the tank container by introducing reinforcing elements into its structure. The results of the strength calculation proved the feasibility of the proposed improvement. The maximum stresses in the tank container are about 215 MPa. Also, as part of the research, a modal analysis of the improved tank container was carried out. It was established that the safety of transportation of a tank container by rail transport from the point of view of modal analysis is ensured. A special feature of the results is that the strength of the tank container was improved by strengthening its frame as the most loaded element of the structure. The field of practical application of the findings is railroad transport. The conditions for the practical use of the results are the placement of braces of the reinforcing element of the frame at an angle of 45° to the horizontal. The results of this study will contribute to new technological advancements in the design of modern structures of tank containers, as well as to improving the efficiency of operation of container transportation
