Carrying out transportation of oil products, there is a danger of having a negative impact on the environment - a leak of liquid can create an environmental problem for a certain area. Transportation of oil-containing cargoes to Ukraine, during martial law, is carried out by multimodal transport, namely, road, sea and rail modes of transport.As of June 2023, there are 14 border railway stations connecting Ukraine with five countries: Poland, Slovakia, Hungary, Romania and Moldova. International railway transshipment stations were studied, which allow oil products to be transshipped into tankers for further customs clearance and transportation to warehouses, civilian or military recipients. The distance of the transportation path is not always decisive in the matter of energy saving. Environmental friendliness and energy consumption during the transportation of petroleum products are also affected by the topography of the road, the landscape of the area where the roads pass, and the traffic on the roads with other vehicles.

Purpose. The main purpose of this work is to provide theoretical support for the need to expand data on changes in the material behaviour under dynamic loads when railway track risk assessment over time due to railway track elements deformability. Methodology. For the research, an original model of railway track design described using the original method based on the ability of elastic waves to propagate energy of power pulses in space and time, as well as a model describing materials as discrete substances were used. Findings. It has been established that the properties of the material affect the deformability of the elements and the design of the railway track; the main parameter in the study of deformability processes is time; material, as a substance, consists of atoms and molecules, and therefore is not continuous; internal physical processes determine changes in the behaviour of the material of an element. Originality. It has been proposed to develop classifications of changes in the physical properties of materials according to the probability of irreversible deformations and the impossibility of deformations, as well as classifications of changes in the mechanical properties of materials according to the probability of the defect appearance and changing the material structure. Practical value. The ability to simulate analytically any physical processes occurring inside elements due to the proposed method allows combining the influence of mechanical and physical effects into a single calculation. This enables to assess the probability of appearing defects in elements under certain dynamic loads when assessing the railway track risk over time due to railway track elements deformability.

The hostilities in Ukraine have significantly changed the logistics of petroleum product supply. Overland routes via EU countries, in particular Poland, Romania and the Baltic states, have become the main transport solution. Rail transport remains the main mode of transportation for petroleum products, providing significant volumes, but faces the challenges of low capacity and delays at the borders. Road transport is showing growth due to the flexibility required in the crisis. The relevance of the work is determined by the need to increase the efficiency of logistics in the face of rising costs of transport resources and economic challenges that may be associated with a large number of both direct and indirect factors (economic, technological, political, security, etc.), the analytical set of which indicates the vulnerability of the security system for the transport of high-risk cargo.
