The only scientific solution to natural calamities is the development of a system to predict, detect and take preventive measure using recent advancement in technology, Railway trail defence structure based on IoT. Using two types of sensor to sense and detect the obstacles. In this project, we implement an idea such as using a camera for live stream monitoring and the sensor to detect the obstacles. The main part of this paper is RPI3 which controls all the operation and passes the information through a webpage. The camera mounted on the front of the vehicle. PIR and ultrasonic sensor are used for sensing the moving and non-moving obstacles. Detecting any obstacles the signal will be sent to RPi3and it will transmit the signal to the webpage. The webpage will be transmitted to the monitor within the monitor the image of the object will appear and the locomotive pilot will turn off the engine. We also used GPS to track the train through the entire path and in which it stops due to any problems.
