A tamper-proof signalling system for railways, currently being developed by IIT-Kharagpur, holds significant importance for the following reasons: 1. Safety: Such a system ensures enhanced safety by minimizing human error and preventing unauthorized access to the signalling system, reducing the risk of accidents and collisions. 2. Prevents sabotage: A tamper-proof signalling system makes it extremely difficult for any malicious actor to tamper with or sabotage the railway infrastructure, ensuring the smooth and uninterrupted operation of trains. 3. Reliable communication: The system improves communication between different sections of the railway network, enabling real-time sharing of information about train positions, speed, and track conditions. 4. Improved efficiency: With a tamper-proof signalling system, railways can optimize train schedules, reduce delays, and improve overall operational efficiency. This can lead to increased passenger satisfaction and cost savings. 5. Enhanced monitoring and maintenance: The system provides continuous monitoring of the railway infrastructure, allowing for timely identification of faults or defects, and facilitating proactive maintenance actions. In conclusion, the development of a tamper-proof signalling system by IIT-Kharagpur promises to enhance safety, reliability, efficiency, and maintenance in the railway industry.
