The Interaction Between Railway Vehicle Dynamics And Track Lateral Alignment [PDF]

open access: yes
This thesis examines the effect of vehicle dynamics on lateral deterioration of the track alignment. As rail traffic runs along a route, the forces imposed upon the track cause the ballast to settle, and hence the track geometry deteriorates.
