Statistical analysis of cone penetration resistance of railway ballast
EPJ Web of Conferences, 2017 Dynamic penetrometer tests are widely used in geotechnical studies for soils characterization but their implementation tends to be difficult. The light penetrometer test is able to give information about a cone resistance useful in the field of ...

Risk Analysis, Volume 45, Issue 5, Page 973-980, May 2025.Abstract Unexploded ordnance (UXO) from the World Wars on the North Sea floor pose an uncertain occupational safety risk for dredging and cable installation. At present mitigation strategies are based on an interpretation of the precautionary principle that uses a worst‐case approach, that is, assuming that UXO will be encountered, will explode, and ...

Impact of wheel shape on the vertical damage of cast crossing panels in turnouts [PDF]
, 2015 Impact forces generated in the load transfer area of railway crossing panels lead to a range of degradation modes from wear and fatigue of the contacting materials, fatigue of supporting components to ballast/subgrade deterioration.

Plant communities responses and effects in railway environment
Weed Research, Volume 65, Issue 3, May/June 2025.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.

Short‐term prediction of railway track degradation using ensemble deep learning
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 10, Page 1314-1343, 18 April 2025.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 ...

Prediction of approaching trains based on H‐ranks of track vibration signals
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 5, Page 614-631, 17 February 2025.Abstract This paper introduces a method for forecasting the arrival of trains by analyzing track vibration signals. The proposed algorithms, based on H‐ranks of track vibration signals, can generate early alerts for approaching trains. These algorithms are robust to additive noise and environmental conditions.
