To keep safety to running on curve, it's very important to reduce wheel load variations of rolling stock on the track cant run-off section. In this study, the cant run-off section is laid on straight track in the yard. On the section, the wheel load variations are measured with various conditions of air spring control system at low speed of the actual vehicle. The results of the test, maximum wheel load variation rate at low speed is decreased very much by improvement of the air spring characteristics, the leveling valve characteristics and differential pressure valve characteristics. Concerning the test results, we suggested better characteristics of the air-spring control system.
