The goals of rail defect management are to prevent rail flaw related operating accidents and to minimize track maintenance costs. This study focuses on the development and evaluation of a novel nondestructive testing (NDT) technique utilizing high-energy lasers to introduce ultrasonic signals into the rail, evaluated by Tecnogamma SPA and the Transportation Technology Center, Inc. (TTCI). The main objective was to enhance detection capabilities of rail defects differing from conventional methods by using a non-contact approach. This laser-based ultrasonic inspection system targets defects located under damaged rail surfaces and allows speed inspections up to 60 mph (96.5 km/h), overcoming limitations of contact methods. The prototype is undergoing testing at the Rail Defect Test Facility (RDTF) in Colorado, where it is designed specifically for various rail profiles and capable of detecting numerous defect types. Ongoing evaluations aim to improve efficiency in rail flaw detection, expecting significant reduction in maintenance costs and prevention of derailments, thereby achieving estimated annual savings of approximately $40 million. The research highlights the potential advancements in rail inspection technology to ensure safer transit operations.
