The paper presents the main results of multivariate modeling of the movement of gondola cars on bogies with axle loads of 23.5 tf (bogie 18-100) and 25 tf (bogies 18-9855 and 18-194-1) in various combinations of track design and technical condition of both cars, and the railway track. Based on the modeling results, recommendations were made for optimizing the running parts in terms of reducing wear on the wheel flanges, and a functional diagram was provided for assessing the service life of the running parts ofcars.
