- The Northeast Frontier Railway (NFR) has launched an Intrusion Detection System (IDS) to protect elephants near railway tracks.
- The system uses optical fibre sensors to detect elephant movement and sends real-time alerts to train drivers and control rooms.
- Pilot installations cover 64.03 km of elephant corridors and 141 km of block sections across four railway divisions.
- The next phase will expand the IDS to 146.4 km of elephant corridors, with full implementation expected by April 2026.
