Dynamical analyses with different conditions of turning radius and velocities were performed and the L/V coefficients were calculated. The results have shown that there was not a best configuration for all conditions of velocities. The magnitudes of the L/V coefficients in the three-point configuration depend on the direction of the movement of the rail car. The fourpoint configuration showed an intermediate performance in all velocities. The best performance could be achieved with the development of a switch system that changes the configuration of the three-point system according to the direction of movement and velocity of the rail passenger car.
