The development of a tamper-proof signalling system by IIT-Kharagpur for railways holds significant importance for the following reasons: 1. Safety enhancement: A tamper-proof signalling system can minimize the chances of human error and malicious interference, thus reducing the risk of accidents and ensuring safer railway operations. 2. Prevention of signal tampering: Traditional signalling systems are vulnerable to tampering and malicious activities, which can lead to catastrophic accidents. By developing a tamper-proof system, IIT-Kharagpur aims to eliminate this threat and improve overall railway security. 3. Increased reliability: With a tamper-proof signalling system, the reliability of railway operations will be enhanced. It ensures that signals cannot be altered or manipulated, ensuring smoother and more accurate communication between train drivers and control centers. 4. Minimal downtime: The implementation of a tamper-proof signalling system can lead to reduced downtime caused by signal failures or inconsistencies. This can result in improved efficiency and fewer delays in train operations. 5. Technological advancement: Developing a tamper-proof signalling system showcases the technological prowess of IIT-Kharagpur. It demonstrates the ability to innovate and implement cutting-edge solutions for critical infrastructure like railways. Overall, the project's significance lies in enhancing safety, improving reliability, reducing downtime, and showcasing technological advancements in the railway sector through the development of a tamper-proof signalling system.
