Measurements of track stiffness and track irregularities todetect short waved support conditions

open access: yes, 2006
Short waved vertical irregularities of the track can cause high dynamic train-track interactionforces. These forces cause several problems, for example deterioration of track geometry anddamage of components.

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.

Influences of cement asphalt emulsified mortar construction on track slab geometry status [PDF]

open access: yesRailway Sciences, 2023
Purpose – The construction of cement asphalt (CA) emulsified mortar can obviously disturb the slab status after the fine adjustment. To decrease or eliminate the influence of CA mortar grouting on track slab geometry status, the effects of grouting ...

The interaction between railway vehicle dynamics and track lateral alignment [PDF]

open access: yes, 2016
Track geometry deteriorates with traffic flow, thus it needs to be regularly restored using tamping or other method. As the deterioration is mainly in the vertical direction this aspect has been widely studied and models for its analysis developed ...
