LRVs, The Next Generation

This article describes the problem of rail track flaws for the railroad industry, costing an estimated $109 million for derailment, $70 million for delays, $149 million for maintenance and repair, and $127 million for inspection annually- all of which point to the necessity of improving the technological efficiency of rail flaw detection. Specifically this article addresses the use of ultrasonic waves using transducer “injection” into the rail. Some limitations are also outlined: the system experiences excessive false readings, the inspection speeds remain slow, the necessity of a clean rail head, and imperfect defect estimation are among them. Research is currently being conducted to improve the speed and efficacy of this system, which remains one of the better analysis methods regardless of its limitations.
