Investigating Root Causes of Railway Track Geometry Deterioration – A Data Mining Approach
Frontiers in Built Environment, 2020 Railway track geometry deterioration indicates degradation in the underlying track structures. Monitoring and predicting this behavior are important as is investigating the root causes contributing to the deterioration.

Detecting Embankment Instability Using Measurable Track Geometry Data
Infrastructures, 2020 The British railway system is the oldest in the world. Most railway embankments are aged around 150 years old and the percentage of disruption reports that feature them is frequently higher than other types of railway infrastructure.

International Journal of Rail transportation, 2023 Ballast layer defects are the primary cause for rapid track geometry degradation. Detecting these defects in real-time during track inspections is urgently needed to ensure safe train operations. To achieve this, an indicator, the track degradation rate (

Railway defect detection based on track geometry using supervised and unsupervised machine learning
Structural Health Monitoring, 2022 Track quality affects passenger comfort and safety. To maintain the quality of the track, track geometry and track component defects are inspected routinely. Track geometry is inspected using a track geometry car (TGC).

MODELING THE TRACK GEOMETRY VARIABILITY [PDF]
Blucher Mechanical Engineering Proceedings, 2014 At its building, the theoretical new railway line is supposed to be made of perfect straight lines and curves. This track geometry is however gradually damaged and regularly subjected to maintenance operations. The analysis of these track irregularities is a key issue as the dynamic behaviour of the trains is mainly induced by the track geometry.

Prediction of track geometry degradation using artificial neural network: a case study
International Journal of Rail transportation, 2021 The aim of this study has been to predict the track geometry degradation rate using artificial neural network. Tack geometry measurements, asset information, and maintenance history for five line sections from the Swedish railway network were collected ...

A Methodology Linking Tamping Processes and Railway Track Behaviour
Applied Sciences, 2023 Today’s railway transport is built upon high-performance infrastructure. Cost-effective yet sustainable infrastructure presumes tracks with a precise and durable geometry. At ballasted tracks, the geometry is created and restored through tamping machines,
