This paper presents the possibility to improve the dynamic performance of trucks by semiactive control for rail vehicles. According to the direction of vehicle motion, the truck parameters are switched in a longitudinally asymmetric manner. A realistic method of semiactive control has been proposed in order to give compatibility between the dynamic stability and perfect steering around curves, i. e., the primary longitudinal stiffness of the trailing axle is larger than that of the leading axle and the primary yaw damper is set only on the leading. The switch for bidirectional operation is made by the change of the damping force of the yaw damper. Another truck for parameter control has been proposed: a truck with unsymmetrical interwheelset structure equipped with the trailing axle rotating independently. This truck is better in high-speed stabildty than a conventional truck if the ability to steer around curves is the same.
