Evaluating infrared imaging and laser ultrasonics as detectors of rail foot flaws

Research Overview

Building on initial ACRI research to further inform rail operation performance and safety with evaluations of infrared imaging for detecting temperature changes in rail foot flaws, and laser induced ultrasonic guided wave techniques for rail foot flaw detection.

Despite significant technological advancements rail foot flaws resulting in breakages of rails still occur and can lead to train derailments.
