Floating slab tracks (FST) are mass-spring systems that are used to reduce groundborne vibration generated by trains. The effectiveness of FSTs can be estimated using the single degree-of-freedom (SDOF) model. More detailed study of the modes and shapes of the FST are sometimes performed using Finite Element Method (FEM) models. This paper also explores the suitability of a natural rubber (NR) based elastomeric spring for FST designs that require relatively high deflection and good performance at low service temperatures (-40 °C). The paper also evaluates the utility of simple SDOF models as a prediction tool, and the potential factors that would result in higher damping at the resonance frequencies (f0).
