Track transitions such as slab track to ballasted track, level crossings and bridge abutments are common locations of accelerated track geometry degradation (differential settlement). In this paper, we studied the mechanism of wheel load variation caused by the change of track stiffness and loose sleepers using a track dynamic model based on the results of the measurements. Then we evaluated countermeasures such as larger sleepers, resilient sleepers and track lifting process.
