Intrusion Detection System:

The Northeast Frontier Railway (NFR) has successfully completed trial works of the Intrusion Detection System (IDS) in four key sections.
- The IDS initiative aims to strike a balance between operational efficiency and environmental protection.
- It is designed to protect wildlife and maintain operational efficiency, especially in areas where railway lines pass through forested and elephant-inhabited zones.
- It runs parallel to tracks at a distance of 10 metres.
- This initiative has been launched by the Northeast Frontier Railway (NFR) under the Ministry of Railways.
- It uses advanced optical fibre sensing technology to detect elephant movement near railway tracks,
- It generates real-time alerts for train drivers and control rooms to take timely preventive action.
- When elephants come close to the railway tracks, the vibrations generated by their movement are detected by the sensor cables, which then transmit signals to the control room.
