Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
The precise tamping mode plays a crucial role in determining the maintenance effects on railway ballasted tracks. Previous studies have focused separately on either the mechanical response or the geometric evolution of tracks, which limits their ...
