Keywords:Railway, Ballast, Subsidence

Railway track ballast is discrete granular material which is an important constituent of track bed substructure. Ballast layer transfers and distributes the load induced by moving train to subgrade and provides drainage layer. Understanding the response of ballast particles to train induced cyclic loading becomes an important aspect of ballast engineering. This study uses the Discrete Element method (DEM) to model the track with ballast particles.
