What is Plan Bee?

  • Plan Bee, is an amplifying system imitating the buzz of a swarm of honey bees to keep wild elephants away from Railway Tracks.


  • For Plan Bee, Northeast Frontier Railway (NFR) earned the best innovation award in Indian Railways for the 2018­19 fiscal year.

Why Plan Bee?

  • There are 29 earmarked elephant corridors with the operating zone of NFR spread across the north-eastern states and parts of Bihar and West Bengal.
  • Trains are required to slow down at these corridors and adhere to speed specified on signs
  • But elephants have ventured into the path of trains even in non ­corridor areas, often leading to accidents resulting in elephant deaths.
