Dynamic effect of high speed railway traffic loads on the ballast track settlement [PDF]

, 2011
The traditional ballast track structures are still being used in high speed railways lines with success, however technical problems or performance features have led to non-ballast track solution in some cases.

Dynanics of a vehicle-track coupling system at a rail joint [PDF]

, 2015
The dynamic behaviour at a rail joint is examined using a two-dimensional vehicle–track coupling model. The track system is described as a finite-length beam resting on a double-layer discrete viscous-elastic foundation.
