Significance of a detection of defects in rails
Non-Destructive Testing, 1970Abstract The article describes the principal types of defects which may be found in rails, and indicates those which are inherent in the manufacturing processes and those which arise as a result of service loads. The principles of resonance and pulse-echo ultrasonic flaw detection as applied to rails are given, and the current ultrasonic testing ...

Fatigue & Fracture of Engineering Materials & Structures, 2003
ABSTRACTFor about 150 years, the steel rail has been at the very heart of the world's railway systems. The rail works in a harsh environment and, as part of the track structure, it has little redundancy; thus, its failure may lead to catastrophic derailment of vehicles, the consequences of which can include death, injury, costs and loss of public ...

Automatic detection of defective rail anchors
17th International IEEE Conference on Intelligent Transportation Systems (ITSC), 2014Rail line anchors/fasteners are the metallic components that attach each line with the sleepers. These are essential rail components as absence of these often result in derailments. Therefore in order to prevent dangerous situations and ensuring safety rail lines are periodically inspected.

A Visual Detection System for Rail Surface Defects
IEEE Transactions on Systems, Man, and Cybernetics, Part C (Applications and Reviews), 2012Discrete surface defects are the most common anomalies of rails and they should be carefully inspected. However, it is a challenge to detect such defects in a vision system because of illumination inequality and the variation of reflection property of rail surfaces.

Morphological Detection and Extraction of Rail Surface Defects
IEEE Transactions on Instrumentation and Measurement, 2020Rail inspection by means of a visual system has been a subject of a number of publications in recent years. The main requirements with regard to such a system are that it has to be fast, nondestructive, and accurate. This article presents a system for rail defect detection and shape extraction utilizing morphological operations.

A dual-rail compact defect-tolerant multiplexer
Microelectronics Reliability, 2015Abstract As the dimensions of CMOS devices scale down to the nanometers, manufacturing defects are becoming a challenging concern in current and future technologies. This work aims at improving defect tolerance in FPGAs which are certainly affected by technology downsizing.

Risk Analysis, 1991
Existing approaches to routing hazardous material shipments by rail recognize that track condition is an important influence, but have not included it in the risk assessment and routing models. This note explores the influence of track condition based on predictions of internal defects in the rail.
