IIT-Kharagpur has made significant contributions to the development of a tamper-proof railway signalling system, enhancing the overall safety and efficiency of the Indian Railways. Here are the key points: 1. Research and development: IIT-Kharagpur has conducted extensive research to develop an advanced signalling system that utilizes artificial intelligence, machine learning, and internet of things (IoT) technologies. 2. Track circuit design: The institute has developed a new track circuit design that enhances the accuracy and reliability of train detection. This improves the efficiency of train operations and minimizes the risk of accidents. 3. Anti-collision system: IIT-Kharagpur has also contributed to the development of an anti-collision system for trains, which prevents collisions by automatically signaling trains to slow down or stop based on real-time data analysis. 4. Communication technology: The institute has worked on improving communication technology between trains and railway control centers. This ensures seamless and reliable transmission of data, enabling better coordination and monitoring of train movements. 5. Testing and validation: IIT-Kharagpur has established a state-of-the-art testing and validation facility to evaluate the performance and reliability of the tamper-proof signalling system. This ensures that the system meets the required safety standards. Overall, IIT-Kharagpur's contributions in developing a tamper-proof signalling system have played a crucial role in enhancing railway safety and efficiency in India.
