The paper considers the development of the simulation models of trains and making calculation of their aerodynamic drag at various speed, load and number of cars in the train. For simulation the finite-volume method in Ansys software was used. The finite-volume method calculation results were compared to analytical calculations and the experimental results. Methodology has been proposed for determining aerodynamic drag of several train consists formed out of gondola cars.
