Railways use AI alerts and Plan Bee to protect elephants
Northeast Frontier Railway is using AI-based intrusion alerts, speed restrictions, patrols and Plan Bee to prevent train-elephant collisions. An October report describes measures across Alipurduar, Rangiya, Lumding and Tinsukia divisions. Plan Bee broadcasts honeybee sounds to deter elephants, while wildlife underpasses and coordination with forest officials support safer crossings.

Why it matters
Elephant collisions threaten wildlife and railway safety. The reported approach combines technology with train-operation changes, habitat crossings and coordination between railway and forest personnel. For India, the policy question is how to build and operate linear infrastructure while maintaining wildlife movement. Alerts are useful only when staff receive them and can respond in time; they complement physical crossings and patrols. Comparing measures across vulnerable routes requires consistent records of incidents and interventions. The inconsistent rescue totals in the current report should not be used as a verified performance statistic.
Prelims pointers
- Northeast Frontier Railway (NFR): the zonal railway whose Alipurduar, Rangiya, Lumding and Tinsukia divisions reported the elephant rescues.
- Plan Bee: a railway deterrent that uses amplified honeybee sounds to keep elephants away from tracks.
- Intrusion Detection System (IDS): AI-based, uses DAS technology to detect elephant movement near tracks and alert crews in real time.
- Underpasses at identified locations give wildlife safer routes and reduce the need for elephants to cross railway tracks.
Practise a UPSC-style question
Consider the following statements about NFR's measures to protect elephants:
1. Plan Bee deters elephants by playing amplified train-horn sounds.
2. NFR has taken up the construction of underpasses at identified locations for wildlife.
3. Railway teams clear vegetation at vulnerable locations.
Which of the statements given above is/are correct?
- (a) 1 only
- (b) 1 and 2 only
- (c) 2 and 3 only
- (d) 1, 2 and 3
Show the answer
Answer: (c) 2 and 3 only
Statement1 is incorrect: Plan Bee plays amplified honeybee sounds. Statements2 and3 are correct: underpasses and vegetation clearing are reported measures. Therefore2 and3 only is the correct option.
