An analysis of wars and armed conflicts shows that the share of railway traffic during mobilization and operational deployment can make up from 70 to 85% of the total traffic volume, which significantly increases the requirements for the stability of the entire railway transport infrastructure [1]. In this case, the safety of railway transport infrastructure refers to the state, where there is no unacceptable risk associated with causing harm to the life or health of citizens, property of individuals or legal entities, state or municipal property, as well as the environment, life or health of animals and plants [2, 3]. Railway troops of the Armed Forces of the Russian Federation are intended for technical cover, reconstruction, demining and blocking of sections (objects) of the railway transport infrastructure within the area of responsibility of the Armed Forces, increasing its survivability and traffic handling capability, as well as planning guidance and operation of floating railway bridges. When reconstructing railway infrastructure facilities, management work organization and rapid recovery of interrupted train traffic are quite important. In turn, this largely depends on the preparation and decision making, which require certain engineering calculations, as well as the provision of a certain spare parts, the lack of which can be replenished through the use of additive manufacturing technology.
