Flaw detectors for high-speed railway rails. Flaw detection for railway rails in China is mainly performed by a large-size rail flaw detection car and smaller multi-channel flaw detector. The large rail flaw detection car is technologically sophisticated, efficient, and highly adaptable, but inflexible, which will be supported by manual inspection. Magnetic induction was the method used on the first rail inspection cars. This was done by passing large amounts of magnetic field through the rail and detecting flux leakage with search coils. Since then, many other inspection cars have traversed the . Sperry ° Service. In , Dr. Elmer Sperry established Sperry Rail Service after successfully developing the world's first non-destructive method of testing rail, saving countless lives in the process. Today, Sperry is the largest provider of Rail Health® services in the world, having inspected well over 12 million miles of track and. The rail flaw detection vehicle includes carriage, wheel probes, ultrasonic modules and software.

Rail Flaw Detection has an important part to play in ensuring the safety of the world's railroads. Recent accidents caused by broken rails have focused attention on the technologies that enable the detection of flaws in railroad rail. This paper reviews the technologies currently employed, along with examples of recent field by: In an effort to reliably scan rails, it was found that grease instead of couplant has some advantages. Chapter 6 provides potential techniques that can be considered to monitor rail base corrosion, particularly with a rail flaw detection vehicle.
