Abstract A simple test procedure is proposed to measure the stiffness of rail fastening systems specifically for the purpose of providing suitable input data to predictive models for ground-borne noise. It is therefore intended to provide stiffness data that is appropriate to the frequencies, amplitudes and types of fastening systems that are relevant to studies of ground-borne noise. The stiffness of the fastening system is found to be dependent on vibration amplitude within the range expected in track. The proposed test procedure allows stiffness measurements to be made over a suitable range of amplitudes and would represent only a small addition to existing standard tests for fastening systems in terms of the resources required.
