Abstract: Railway is the most prominent and most economical way of transport. Majority of people depend on railways for transportation. Rail modes are most commonly used and very effective mode of commuting and goods carriage over long, short distances. In this paper, we are preparing a system in order to prevent the disasters which happen due to unmanned level crossing in the railways. For this system, Arduino Uno is used as the platform with ATMEGA16U2 as the microcontroller. In order to detect the train as well as the obstacles ultra-sonic sensors are used. When the train approaches the unmanned zone, ultrasonic sensor will detect the arrival of train which is kept 2 KM away from the railway crossing zone. The input of ultrasonic sensor is sent to Arduino Uno to activate the railway gates operated by DC motors. These gates are controlled or driven by motor driver circuit. If any obstacles are detected on the track can also be detected by the ultrasonic sensors which are kept at the gate and it will alert the train, with the help of led signal. Due to this led signal, the train will slow down the speed mechanically or even the train can stop if it’s necessary. This system is demonstrated to prevent and stop the disaster at railway crossing zones.
