Accurate prediction of the mechanical behaviour of railway tracks subjected to train-induced repeated loading is crucial for their effective design and maintenance planning. Various approaches have been developed to accurately simulate key aspects of railway track behaviour. This keynote paper highlights recent advancements in computational modelling techniques and their application in predicting railway track performance. Firstly, the finite element (FE) technique is utilised to assess the load transfer mechanism between rigid concrete piles and adjacent subsoil supporting a railway embankment. The influence of spacing between concrete piles on the mobilisation of soil arching is assessed. The FE method is also applied to evaluate the performance of both ballasted and slab tracks, comparing the vertical stress variations and cumulative settlement in each track type. Additionally, an innovative computational technique based on a geotechnical rheological model is showcased that can be employed to predict the long-term performance of standard railway track sections and transition zones.
