Abstract
This study presents a novel approach for detecting fouling in rail bed ballast using an embedded, passive wireless sensing technique. The system utilizes a passive wireless sensor based on a harmonic transponder design, which generates a measurable signal when interrogated. By analysing the attenuation in the received signal moisture levels in the fouled ballast can be assessed, which provides a reliable indicator of ballast fouling. Through a series of controlled laboratory experiments on ballast at different percentages of fouling and moisture, we are characterizing the response of the sensing device.
