<h5>What is the KAVACH system?</h5><p>The KAVACH is an Automatic Train Protection (ATP) system. It was developed by the Research Design and Standards Organisation (RDSO) in partnership with other organisations. The development of KAVACH, first known as the Train Collision Avoidance System (TCAS), began in 2012 and was completed in 2022.</p><p>The trials for the system were conducted by the South Central Railways, which Railway Minister Ashwini Vaishnaw inspected.</p><h5>How does KAVACH work?</h5><p>KAVACH protects trains by preventing them from passing over the red signal and crashing with each other. It automatically activates the train's brakes if the driver fails to control the train within the speed limit. During an emergency, it also sends out distress messages. The Network Monitor System also provides live monitoring of train movements.</p><p>The TCAS helps communicate between the station master and loco-pilot by using various technologies on the locomotive and the stations.<br>The instruments in the train’s cabin notify the loco-pilot of the signal in advance and the permissible speeds to be maintained.</p><p>Furthermore, the train’s hooter engages automatically while approaching a level crossing. This helps the loco-pilots during foggy situations, which causes low visibility. KAVACH is an affordable technology with a very low chance of error.</p><h5>Where has KAVACH been deployed?</h5><figure class="image"><img src="https://firebasestorage.googleapis.com/v0/b/newsahoot.appspot.com/o/indian-railways-kavach-system%2FStation.jpg?alt=media&amp;token=6a83d746-071f-4570-8797-b9bb33a488f6"><figcaption>Train standing at the Siliguri station.

Currently, work is being done to implement the system on the Delhi–Mumbai and Delhi–Howrah routes (around 3000 Rkm). There are also plans to implement the system on another 6000 Rkm.</p><p>Recently, the newly launched second Varanasi-New Delhi Vande Bharat Express was equipped with the KAVACH system. However, railway officials say that installing only KAVACH’s loco component (the part of the KAVACH system installed in a train) is ineffective in protecting a train from collision. The whole system has to be installed on the train's entire route, such as stations, signal towers along the track, etc.</p><p>KAVACH will only work on railway sections with all the system components installed. So, the government must ensure KAVACH components are installed in all Indian railway sections to provide better protection to the people.</p>
