To safeguard elephants, NFR will install acoustic technology throughout the rail network.

B O News Desk : The Northeast Frontier Railway (NFR) has announced plans to implement advanced acoustic-based technology across its network by April 2026 to prevent elephant fatalities caused by speeding trains, officials said.

NFR Chief Public Relations Officer Kapinjal Kishore Sharma said the Intrusion Detection System (IDS), which uses optical fibre sensing to detect elephant movement near railway tracks, has already been successfully trialled in four key sections.

The system generates real-time alerts for train drivers and control rooms, allowing timely preventive action.

“This initiative is aimed at ensuring the safety of elephants while maintaining smooth train operations across forested and elephant-inhabited zones,” Sharma said.
