Monitoring railway rail roughness using on-train vibration measurements
The growth of roughness on the rails of railway tracks is a significant problem that leads to increased noise and vibration emissions that affect residents near the railway. This study is devoted to a novel method of measuring rail roughness to inform maintenance operations. Unlike existing …

A Polynomial Chaos Approach for Stochastic Modeling of Dynamic Wheel-Rail Friction
… (CoF) is essential to accurately modeling railroad dynamics, reducing maintenance costs, and increasing safety factors in rail operations. The assumption of a constant CoF is popularly used in simulation studies for ease of implementation, however many evidences demonstrated that CoF …
