Abstract

Our paper deals with the process of automatic working of opening and closing the railway gate by using sensors and PLCs to make the process easy. We have also added an additional safety alert system in order to save the people who accidentally or wontedly get trapped into the gate when the train arrives by alerting the people nearby using an alarm system to inform them and come to save the people.

Key words: PLC, Automatic Railway Gate, Sensors, WPL Software, Safety Alarm
