Indian Railways has introduced a cutting-edge technology named 'Gajraj' to prevent elephant accidents on railway tracks. It uses an AI-based algorithm and a network of sensitive optical fibre cables to detect elephants getting close to railway tracks. Gajraj Suraksha senses pressure waves generated by the movement of elephants along the tracks. As elephants move, the optical fibres detect vibrations caused by their footsteps. These vibrations trigger signals within the optical fibre network, enabling the system to identify the presence of elephants up to 200 meters ahead of their arrival on the track
