What is it about?
This article show a study on the load deformation of ballasted rail tracks subjected to cyclic loading using a large-scale track process simulation apparatus and numerically through a combined discrete element–finite-difference approach.

Why is it important?
This is an important study that could help railway practising engineers explore more in-depth into the micro-mechanical behaviour, such as contact force distribution, fabric and anisotropy changes of railway ballast contaminated by clays under train loadings.
