Mathematical models are extremely limited at modeling ballast, the gravel layer located under railway tracks. Researchers have shown that a large part of the energy introduced by a train passing is trapped by the ballast. Their work shows that this trapping phenomenon, which is very dependent on train speed, could cause accelerated ballast degradation in railway tracks.
