Railway maintenance workers face high accident risks due to poor visibility and lack of real-time alerts. This project proposes a LoRa-based Smart Safety Alert System with a train transmitter and a wearable wristband receiver. The system provides instant alerts through LED, vibration, and display, and uses two-way communication to estimate worker distance using RSSI. It is low-cost, energy-efficient, and works without internet, making it ideal for remote railway areas while improving worker safety.
