Railways installed sound emitting system to drive away elephants

The Railways have installed a sound-emitting system to scare away elephants at Walayar.

Elephant deaths on the railway tracks had increased recently, raising concerns from various sections of people. Railway officials commissioned the new alarm beacons on Tuesday. The new system will function on solar energy.

The system will make the buzzing sound of honey bees and the roaring sound of tigers. The sound emitted from the beacons can be heard up to 500 metres. Railway officials said that the device, during trials, was found to have been successful in preventing elephants from approaching the rail tracks.

The trigger unit of the system will function at Walayar Railway Station. The sound generator unit functions at a field near the track at the mouth of a cutting. The trigger unit and the sound generator unit communicate through a GSM modem.

An SMS is sent for every control command from the trigger unit, and the sound generator unit acts accordingly and sends feedback commands through SMS. A female elephant and two calves were killed after being hit by the Mangaluru-Chennai express train while crossing track A on November 26.

The railways and the forest department are taking preventive steps to avoid such incidents. Solar-powered lights were installed at some places and plans are afoot to install solar-powered fences to block the entrance of elephants.
