The Northeast Frontier Railway (NFR) is set to roll out an advanced acoustic-based Intrusion Detection System (IDS) by April 2026 to prevent elephant fatalities caused by trains. The IDS uses optical fibre sensing to detect elephant movement near railway tracks, generating real-time alerts for train drivers and control rooms to take timely action. Trials of the system have been successfully completed on four important sections, covering 64.03 km of elephant corridors and 141 km of railway block sections. NFR plans to extend the system to cover the remaining 146.4 km of elephant corridors in its network. This initiative balances wildlife conservation with safe and efficient train operations in forested, elephant-inhabited zones, reaffirming NFR’s commitment to sustainable development and environmental stewardship.
This national-level project sets a benchmark for responsible railway operations in biodiversity-rich areas. It integrates technology with conservation to ensure passenger safety while protecting elephants from train collisions.
