Simulation of Delamination Evolution of Slab Ballastless Track under Vertical Impact [PDF]
Shock and Vibration, 2021 During the running of a high‐speed train, the wheel may bounce on the rail due to the track irregularity. The wheel bounce could generate a vertical impact, leading to the initiation and expansion of delamination between layers of the track structure.

Collision derailments on bridges containing ballastless slab tracks [PDF]
Engineering Failure Analysis, 2019 Train derailment on bridges is an infrequent event, yet when it occurs, it's usually catastrophic. These incidents can toss-out part of the derailed train from the bridge deck and collapse whole or a part of the bridge. Understanding the derailment mechanisms of trains on bridges and identifying the dynamic characteristics of bridges subjected to the ...
