Intrusion Detection System (IDS)

Source:  IE

Context: The Northeast Frontier Railway (NFR) has implemented an Intrusion Detection System (IDS) across key elephant corridors to prevent elephant deaths caused by train collisions.

About Intrusion Detection System (IDS):

What it is?

  • An AI- and sensor-based surveillance mechanism that uses optical fibre cables to detect movement of elephants or other wildlife near railway tracks and alert control rooms instantly to prevent collisions.

Launched by: The initiative has been launched by the Northeast Frontier Railway (NFR) under the Ministry of Railways.

Aim:

  • To reduce elephant fatalities due to train collisions in sensitive wildlife corridors.
  • To ensure safe train operations and improve human–wildlife coexistence.
  • To integrate technology-driven conservation measures into railway management.

How it Works?

  • The system uses vibration-sensitive fibre optic cables laid along railway tracks.
  • When an elephant or large animal moves near the tracks, the vibrations trigger real-time signals.
  • These signals are transmitted to control rooms and train drivers, enabling immediate speed regulation or halting of trains.
  • The alerts are also used to monitor wildlife movement trends for long-term conservation planning.

Key Features:

  • Coverage: Operational in four pilot sections across Alipurduar, Lumding, Rangiya, and Tinsukia Divisions, covering 64.03 km of elephant corridors.
  • Expansion Plan: To be extended to an additional 146.4 km by April 2026, taking the total network to 210 km.
  • Dual Functionality: Provides wildlife protection while maintaining operational efficiency.
  • Real-time alerts: Allows instant communication between field sensors and central monitoring systems.
  • Data integration: Enables long-term data collection for route planning and habitat preservation.
