This project presents a Smart Railway System Using IoT that enhances safety by automating railway gate control and train monitoring. It combines sensors, microcontrollers, and wireless communication to detect train movement, control gates, and provide real-time location updates through an IoT platform.

The Smart Railway Management System is an IoT-based project designed to enhance railway safety and automation. It consists of two main units — a Train Unit and a Station Unit. The Train Unit detects obstacles on the track using an IR sensor and sends real-time GPS location data to the Blynk IoT platform if any fault occurs. Meanwhile, the Station Unit automatically manages railway crossing gates using IR sensors and servo motors, displaying alerts on an LCD and activating visual and audio indicators. This system helps prevent accidents, reduces human intervention, and improves the overall efficiency of railway operations.

Train Unit
The train moves forward normally.
If an obstacle is detected on the track, the train stops and a buzzer sounds.
The train sends its GPS location to the Blynk app for monitoring.
Station Unit
When the train is approaching (detected by IR sensor), the gates automatically close.
Red LEDs and buzzer turn on to warn nearby vehicles.
After the train passes (detected by second IR sensor), the gates open, and green LEDs turn on.
