An initial investigation on the potential applicability of Acoustic Emission to rail track fault detection. [PDF]
, 2004 In light of recent accidents in the rail industry, the assessment of the mechanical integrity of rail-track is of vital importance. This encompasses the integrity of the track due to rolling contact fatigue and surface wear. Whilst numerous techniques

The Effectiveness of Distributed Acoustic Sensing (DAS) for Broken Rail Detection
Energies, 2023 Broken rails remain one of the main causes of railway accidents despite improved rail quality and inspections. Today, signalling system with track circuits are often used to detect broken rails, however new signalling systems such as the European Train ...

Characterization and mitigation of wheel-rail impact at a singular rail defect
Journal of Vibration and Control, 2022 Wheel-rail impact, which arises from structural discontinuities and short-wave defects, becomes more serious with higher train speeds and larger axle loads. The large impact load can accelerate the deterioration of vehicle-track components and induce a high level of impact noise.

Reliability of rail transverse flaw detection by means of an embedded ultrasonic based device
MATEC Web of Conferences, 2018 The main causes of train derailment are related to rail defects such as head surface defects, horizontal defects, vertical longitudinal split defects, star cracks at colt holes and diagonal crack in web. The most adverse form of these defects consists of

Signature analysis on wheel-rail interaction for rail defect detection [PDF]
4th IET International Conference on Railway Condition Monitoring (RCM 2008), 2008 Fibre Bragg Grating (FBG) sensors have been installed along an existing line for the purposes of train detection and weight measurement. The results show fair accuracy and high resolution on the vertical force acted on track when the train wheels are rolling upon. While the sensors are already in place and data is available, further applications beyond

Enhancing RCF rail defect inspection on the Serbian railway network [PDF]
Građevinski Materijali i KonstrukcijeThe interaction between the wheel and the running rails within the railway system introduces intricate stress patterns, resulting in the formation of rolling contact fatigue (RCF) rail defects. The magnitude of this stress is contingent upon factors such
