Abstract- Railway transportation is one of the most widely used and efficient means of transport worldwide. However, railway accidents due to track failures pose a significant threat to human lives and infrastructure. Cracks and irregularities in railway tracks can cause derailments, leading to catastrophic accidents. To address this problem, we propose a Smart Railway Safety and Track Monitoring System that detects track anomalies using ultrasonic sensors. And ultrasonic sensors are connected to 180° servo motor. The system is designed to continuously monitor the track condition, and if the distance between the track and the ultrasonic sensor exceeds 5 cm, it Indicates a crack or damage. Upon detection of an anomaly, the system triggers a series of safety measures: it sends an alert to the nearest railway station via the Blynk IoT app, transmits a text message with GPS coordinates using a GSM module, and initiates an automated phone call to the concerned authority. Additionally, signal lights positioned beside the track serve as a visual warning, turning from green to red upon detection of a crack. The entire process is controlled by an ESP32 microcontroller, ensuring real-time monitoring and efficient safety measures.
