| Abstract: | The feasibility of adopting 25t axle load freight cars is discussed from the aspects of quasi-static effect, vertical dynamic effect, and vibration influence of track. The heavy mass and low stiffness track structure is proposed. It is shown that low wheel/rail interaction and low vibration in case of heavy axle loads could be obtained by using modern railway operating experiences and advanced techniques. |

| Keywords: | large size freight car heavy axle load track dynamic interaction feasibility |
