SNCF engineers have been using mathematical models for many years to simulate the dynamic behavior of railways. These models have not been able to take into account large portions of the track have ...

Results of an EPFL study on ballast projections in exceptional winter conditions have enabled SBB to set-up measures to improve safety around the tracks. SBB transports close to one million passengers ...

Track ballast, made of hard grey stones like granite, stabilises railway tracks by distributing weight, aiding drainage, absorbing vibrations, preventing weed growth, and easing maintenance. Indian ...

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 ...
