Abstract

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
Curved railway tracks are susceptible to lateral instability due to the combined effects of centrifugal forces, reduced ballast confinement, and thermally induced stresses in continuous welded rails. These factors increase the risk of track misalignment, ...
