Ultrasonic wheel inspections for railway infrastructure face significant limitations, particularly in detecting subsurface defects due to masking effects from shallow cracks and limited coverage during inspection. This study aims to address these drawbacks by investigating the application of ultrasonic guided waves for rail inspections, which have the potential to enhance defect detection and inspection efficiency. A detailed evaluation of guided wave propagation characteristics is conducted, revealing their capability to interact with critical internal defects while traversing beneath shallow cracks, thus increasing detection efficacy. Furthermore, the mid-frequency range of 20 kHz to 1 MHz allows guided waves to penetrate alumino-thermic welds, enabling the identification of weld-related defects. The research highlights how guided waves improve coverage and inspection speed over traditional methods by allowing simultaneous assessment along the rail length. However, effective management of guided wave propagation behavior poses challenges for implementation. Overall, the findings suggest that incorporating ultrasonic guided waves into rail inspection protocols can significantly bolster safety measures and maintenance practices for railway systems.
