Abstract

Railway safety critically depends on the structural integrity of tracks, where undetected cracks or fractures can result in derailments and severe casualties. This paper presents a Voltage Standing Wave Ratio (VSWR) based railway track crack detection and prevention system utilizing high-frequency transmission line principles. Railway tracks are modelled as transmission lines through which a controlled radio-frequency (RF) signal is injected. Structural discontinuities such as cracks, fractures, corrosion, or material degradation introduce impedance mismatches, leading to measurable changes in VSWR. The proposed system continuously monitors VSWR variations using an RF signal generator, directional coupler, VSWR sensing unit, and a microcontroller-based processing module. When abnormal VSWR values exceed predefined thresholds, the system generates real-time alerts and can initiate preventive actions by interfacing with railway signalling infrastructure. The system provides a continuous, non-invasive, and scalable solution for railway track health monitoring, reducing dependence on manual inspection and enhancing operational safety.
