A railway track model with the tuned rail damper (TRD) is developed to simulate the system's dynamic response. Two criteria are proposed to estimate the inherent performance and practical effects of the TRD on railway rolling noise. Analysis and simulation results demonstrate that the inherent property of the TRD does not change, but its practical effects may vary with environmental conditions. The theoretical predictions are validated by in-situ measurements. The proposed methodology, which combines the simulation results with the measurement data, is straightforward and easy to use for estimation of the practical effects on rolling noise reduction of the TRD to be used.
