Railway safety is a crucial aspect of rail operation across the globe. In our country, there are no strong steps are taken against the unmanned level crossings and due to this accidents are increasing day by day. There is a huge increase in number of accidents as compared to last decade. India's railway system is the biggest railway network all over the Asia. And this huge network cannot be handled manually. To manage each and every railway crossing manually is not possible. Our paper basically deals with a prototype model of automatic railway barricades and discussed its working and construction. To avoid these accidents and to save road users time we have designed it. In this research work, we have placed two sensors near to the gate and these sensors will detect the arrival of the train and road users will be informed using traffic lights about the status of the train. This whole operation is automatic there is no need of human powers and is less risky and less time consuming. This automatically operatable railway barricades has increased safety of users. There are many countries in which this automatic gate control system has been implemented. In Japan, it is labeled as Automatic Train Control (ATC). Other countries with successful implementations of this system are South Korea,United Kingdom,United States, Africa etc.
