The author explores various theoretical aspects of railway vehicle riding performance as an aid to the rationalization of bogie design. It was shown that low ride index values can be retained by minimizing the natural frequency and/or the amplitude of the oscillation. The importance of damping with respect to amplitude ratio is shown and it is pointed out that dampers are actually undesirable at speeds in excess of 1.41 of the resonance speed. It is also pointed out that damping is of relatively little importance with short swing links. In order to determine the ride index of a rail vehicle, the magnitude of excitation amplitudes, the natural frequency and the damping factor of the system must be known.
