Physica A: Statistical Mechanics and its Applications, 2001 We present a one dimensional model for the development of corrugations in roads subjected to compressive forces from a flux of cars. The cars are modeled as damped harmonic oscillators translating with constant horizontal velocity across the surface, and the road surface is subject to diffusive relaxation.

Study on a Heuristic Wheelset Structure without Rail Corrugation on Sharply Curved Tracks
Shock and Vibration, 2021 Rail corrugation on low rails of sharp railway curves is still a difficult problem to solve worldwide. Nearly all low rails of the sharp railway curves incur rail corrugation. In the present study, an active method to remedy rail corrugation was studied.
