The Importance of Rail Inspections in the Urban Area -Aspect of Head Checking Rail Defects [PDF]
Procedia Engineering, 2015 AbstractControl of railway noise is very significant part of the urban traffic policy. An increase of railway noise could significantly reduce the quality of life of citizens. This paper analyzes and suggests necessary measures for managing railway noise and traffic safety by rail inspection and grinding.

Dynamic Wheel–Rail Interaction Over Rail Squat Defects
Acoustics Australia, 2015 Dynamic interaction between wheel and rail generates vibration and acoustic radiations transmitted through other media such as structural track systems, air, and rolling stock. Noteworthy, both wheel and rail irregularities often induce additional impact vibration and noise along the rail corridor.

AN APPROACH FOR RISK ASSESSMENT OF RAIL DEFECTS
International Journal of Reliability, Quality and Safety Engineering, 2010 Rail defects appear in a greater variety and frequency due to higher axle loads and increasing traffic density in passenger and freight trains. Many of these rail defects, if left undetected, can develop into rail breaks, which may lead to train derailments.

Method and instrumentation for detection of rail defects, in particular rail top defects
, 2011 A method and instrumentation for detection of rail defects, in particular rail top defects, in a railway-track by measuring an axle box acceleration signal of a rail vehicle, wherein a longitudinal axle box acceleration signal is used as a measure to detect the occurrence of said rail defects, in particular rail top defects.

Evolution of the Contact-Fatigue Defects Caused Rail Failure Rate
Вестник Научно-исследовательского института железнодорожного транспорта, 2015 There is discussed current situation and problems of rail damageability in operation. It has been indicated that contact-fatigue defects coded as 10, 11, 17, 21 in the standing catalogue of rail defects represent the main type of rail defects responsible

An Intelligence Method for Recognizing Multiple Defects in Rail [PDF]
Sensors, 2021 Ultrasonic guided waves are sensitive to many different types of defects and have been studied for defect recognition in rail. However, most fault recognition algorithms need to extract features from the time domain, frequency domain, or time-frequency domain based on experience or professional knowledge.

Extending service life of rails in the case of a rail head defect [PDF]
Journal of the Croatian Association of Civil Engineers, 2021 Rails are subjected to the processes of wear, corrosion and contact and bending fatigue during their lifecycle. As a result of these processes, various types of damage and defects are formed in rails. The residual life of rails depends on the size, position, and orientation of defects.
