Answer: Northeast Frontier Railway
Notes: The Intrusion Detection System (IDS) has been launched by the Northeast Frontier Railway (NFR) under the Ministry of Railways. It has successfully completed trial works in four key railway sections. The system aims to protect wildlife, especially elephants, while maintaining operational efficiency in forested areas. The IDS runs parallel to railway tracks at a distance of 10 metres. It uses advanced optical fibre sensing technology to detect elephant movements near tracks. The system sends real-time alerts to train drivers and control rooms for preventive action. Elephant-generated vibrations are detected by sensor cables and transmitted to the control room.
