Stiffness of concrete tie track can be reduced by introduction of resilient pads under the rail; yet, if too much flexibility is introduced, there is danger of losing stability of the rail. Thus arises the problem of selecting optimal resilience of the pads. The system of the interaction of wheel and rail can be represented as a system with six degrees of freedom. Selection of values for the various parameters is quite complex. The author assumed the masses of various components taking part in the oscillation to be proportional to their deflection under a single concentrated force. It was concluded that: the reduction of joint stiffness for more universally used track reduces dynamic effect of wheel to rail action, reduces stresses in wheel and acceleration input to the car, the recommended value of stiffness is of the order of 100 x 10 to the third power Klg/cm, and the values of inertia force can be considered as a linear function of speed.
