Indian Railways is one of the largest and busiest railway networks in the world by carrying millions of passengers and freight every day. To manage such a complex and dynamic traffic, the Indian Railways use an interlocking system that controls the movement of trains and prevents collisions and derailments.
An interlocking system is a set of signals, points, and track circuits that work together to ensure that only one train can occupy a section of track at a time. The system also ensures that the points, which are devices that switch the direction of the track, are correctly set and locked before a train can proceed. The system also controls the level crossing gates, which are barriers that prevent road vehicles from crossing the railway tracks.
The interlocking system can be mechanical, electrical, or electronic, depending on the technology used. The most advanced and modern system is the electronic interlocking (EI) system, which uses computer-based software and hardware to process the commands and inputs from the yard and panel. The EI system can handle more complex and flexible operations, and can also detect and correct errors automatically.
The interlocking system is a vital safety mechanism that ensures the smooth and efficient functioning of the Indian Railways. It reduces the chances of human error and negligence, and enhances the security and reliability of the railway network.
