Plant communities responses and effects in railway environment
Abstract Weed control in rail environment is essential to ensure safe and efficient train operation. Until May 2019, the RATP Group (Régie Autonome des Transports Parisiens, Autonomous Parisian Transportation Administration) exclusively used glyphosate for weed management on its open‐air railway network.

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

Short‐term prediction of railway track degradation using ensemble deep learning
Abstract Short‐term prediction of track degradation facilitates flexible and efficient maintenance, thereby meeting the railway system's escalating demands for track safety and smoothness. However, the track condition evolution presents challenges to accurate prediction, with diverse influential factors resulting in heterogeneous degradation patterns ...

Job order assignment at optimal costs in railway maintenance [PDF]
Tamping is an important part of railway maintenance. Well tamped ballast reduces track irregularities and increases travel safety and comfort. But if the ballast is in a bad condition, the train speed must be restricted, which leads to delays and penalty

Modeling and Characterization of Complex Dynamical Properties of Railway Ballast
The nonlinear mechanical properties of ballasted tracks along railways result in complex dynamics of the vehicle–track systems. Employing localized characterization of ballast and a simplified model might underestimate the vehicle–track system’s ...
