On the basis of the analysis of statistics of the incidents which have occurred on the railroads of Russia and connected with collisions of trains with obstacles, the most probable scenarios of development of an emergency situation are allocated. Modern methods of investigation of kinematics and dynamics of vehicles are analyzed. By methods of solid-state computer modeling the estimation of the dynamic loadings acting on the locomotive and passenger cars at collision of the passenger train with an obstacle in the form of the lorry on the railway crossing is carried out. For this purpose solid-state computer model of a passenger train and a cargo car. The obtained results indicate a high dynamic load of the locomotive in a collision. At the same time, passenger cars are affected by low dynamic loads that do not lead to damage to the load-bearing structures of passenger cars. The obtained results can be used in the creation of modern passenger rolling stock, characterized by high demands on safety in emergency situations. The work was carried out within the grant of the President of the Russian Federation for the state support of young Russian scientists MK-2881.2018.8.

The analysis of the causes of low efficiency of existing knowledge about the dynamics of the locomotive traction drive. It was found that the use of scientific information is difficult because of its inconsistency and lack of systematization. The classification of dynamic phenomena in the locomotive traction drive to facilitate the search for new technical solutions. Classification is used to create a new design rubber-cord coupling protected by a patent.
