This paper presents a novel wayside rail monitoring system for real-time detection and quantification of surface cracks with sub-millimeter precision. The core innovation lies in mounting piezoelectric transducers on the web rail—an unconventional practical location that avoids interference wheel passages while enabling continuous real-world conditions. Moreover, to directly quantify crack depth, customized signal processing pipeline is developed, employing acoustic waves (SAWs) incorporating parallel reference transducer pair mounted an undamaged section calibration. auxiliary provides calibration baseline, improving measurement robustness accuracy. method experimentally validated samples verified through metallographic analysis. approach enables condition-based maintenance by accuracy offers potential reduce operational costs enhance railway safety.
