Research work on rail corrugation phenomena is mostly focused at trying to explain the mechanism by which these corrugations are formed and to some extent, the environmental consequences represented by the noise of trains passing corrugated sections of track. In this work, it is the effect of environment as a corrugation catalyst that is studied.
In certain countries of the Middle East, sections of some railway lines pass through dry desert areas where the dominant sand storms keep fine sand particles in continuous motion.
The work presented in this paper describes rail table corrugation phenomena observed in sections of Aqaba Railway Company track in light of the effect of moving sand as a ballast contaminant. Sand fine particles hinder the motion of ballast gravels by filling the voids between these gravels to result in increased track stiffness and damping.
