The article presents the results of determining the dynamic load of the load-bearing structure of the tank container placed on a roll-trailer during transportation by railway ferry. For this purpose, a mathematical model was developed, which takes into account the dynamic loading of the tank container during angular displacements of the railway ferry. It is taken into account that the roll trailer is rigidly fixed on the deck, and the tank container and the liquid cargo in the boiler have their own degrees of freedom. The obtained accelerations are taken into account when calculating the stability of the tank container on the roll trailer. Thus the stability of the tank container is provided at lurch angles to 240. The carried-out researches will allow increasing safety of transportations of tank-containers on railway ferries by the sea, and also the efficiency of functioning of combined transportations in the international communication.

A study of the dynamic loading of the carrying structure of a tank wagon during transportation on a railway ferry was carried out. The studies were carried out with the angular displacements of the railway ferry around the longitudinal axis (lurch), as the case of the highest load on the carrying structure of the tank wagon. It was found that the acceleration total value that acts on the outermost tank wagon from the bulwark is 0.31g. The resulting value of acceleration, as a component of the dynamic load, was taken into account when calculating the strength of the carrying structure of the tank wagon, taking into account the typical scheme of interaction with chain ties. The research carried out will contribute to the creation of recommendations for the safe operation of tank wagons in international rail and water traffic and increasing the efficiency of rail transport functioning.
