Ballasted tracks are essential for transporting goods and passengers between major urban areas and ports, but they suffer breakage, fouling and excessive deformation from repeated train loads. This study investigates the effect of loading and frequency on ballast deformation and degradation through lab tests and numerical modelling. A coupling model based on the finite element method and discrete element method is introduced to predict load-deformation behaviour. DEM represents ballast grains, while FEM models the subgrade, accounting for their interactions. The model is applied to analyze a Singleton, Australia track, with numerical results compared to field data for validation.
