Research on ultrasonic guided wave-based high-speed turnout switch rail base flaw detection

Proceedings of the Institution of mechanical engineers. Part F, journal of rail and rapid transit
Turnout switch rail fracture detection is currently a serious issue in the field of railway transportation. Guided wave detection, a non-destructive testing method, is a good way of studying this issue and looking for a suitable solution. For this paper,

The Design of a Non-Contact Inspection System Integrated With the Time of Flight-Based Flaw Detection (TOFFD) Criterion to Investigate the Structural Integrity of the Rail Track

IEEE Transactions on Instrumentation and Measurement
Rail flaws can be initiated either from manufacturing or service-related anomalies. These flaws may lead to train derailment while in service if not detected timely.

Method for detection of a flaw or flaws in a railway track, and a rail vehicle to be used in such a method

2013
Rail vehicle (1) having rail wheels (3,4) accommodated to guide the rail vehicle along a railway track (2) and said vehicle comprising means for detection of a flaw or flaws in the railway track, wherein the rail vehicle is provided with a noncontact vibrometer (9,10) which is arranged to measure vibrational movement of the railway track surface.
