In paper has been carried out to develop a load-bearing floor to increase the carrying capacity of the solid-body rail freight car. An analysis of the structures made it possible to formulate the hypothesis that the load-bearing floor of the solid-body rail freight car should have a different cross-sectional shape. As a result, the load-bearing floor of the solid-body rail freight car was proposed, making it possible to reduce the consumption of materials by 1 to 2%. The maximum equivalent stresses (according to Mises) of the proposed load-bearing floor of the solid-body rail freight car in static analysis are 210.7 MPa, which is less than the yield limit of simple carbon steel. The proposed technical solution allows one to increase the carrying capacity of the solid-body rail freight car by 1.4-1.7 tons. The proposed technical solutions for the future operating conditions of rail freight cars make it possible to reduce the number of units in a train by 1-2 units while maintaining the gross weight of the train.
