The article presents an overview of modern plastics for use in rail vehicles. The analysis of plastics and composites in the constructional aspect was analyzed. The trends in the development of polymer materials, technologies and constructions used in the manufacture of vehicles, on the one hand, are determined by the technical and economic requirements of industry and, on the other, by the continued emphasis on reducing fuel consumption and CO2 emissions. Further development will be subject to pre-impregnation techniques, particularly in the form of different types of reinforcement. Full use of the advantages of reinforced polymer materials in vehicle production will only be achieved when further optimization of the resin properties and development of automation will result in the widespread use of composite components in series production. Observing the trends and pace of development, it is possible to predict that there are still restrictions on the use of polymeric materials in the transport sector, such as relatively high prices, technological constraints and the hindering automation of large-scale production. Modern construction and material solutions, in particular those using reinforced plastics, are primarily designed to reduce vehicle weight and have better noise and vibration damping properties. Rail vehicles are becoming more environmentally friendly at the time and travel comfort is higher.
