Elephant deaths on and near the state's railway tracks are rising, with 36 fatalities recorded from train collisions in the past decade, according to official data.

Eleven of these fatalities occurred on two railway tracks near Madukkarai, where the forest borders the state of Kerala. These tracks intersect with the elephants' migratory route to neighbouring forests.

In 2021, the state's high court ordered the forest department and railways to prevent elephant deaths on these tracks.

The forest department has now installed 12 towers along two of Madukkarai's rail tracks, each equipped with an AI camera capable of thermal and visible light

Project manager Ashish Rajput said that the AI system's cameras, comparable to those used by the Indian Army along the nation's borders, are programmed to even detect humans near railway lines.

When elephants are detected within 100ft of the railway track, alerts are sent to forest and railway officials, who coordinate to slow down trains and guide the elephants away to prevent collisions. Four personnel continuously monitor the system in the control room near the railway track.

The project, launched in February, has been executed at a cost of 72.4m rupees ($867,758; £683,976), says Supriya Sahu, secretary of the Tamil Nadu Forest Department.

Previously, forest personnel conducted regular patrols along railway tracks to monitor elephant activity. Ms Sahu said this method had limitations, and ensuring complete elephant safety from accidents posed "significant challenges".

Within months of its implementation, the AI system has detected nearly 400 instances of elephants approaching railway tracks and promptly reported to railway authorities, thus preventing potential accidents, she said.

"Alerts are sent if any animal, not just elephants, is found nearing the track," say Mr Manikandan, who works at the control room.

This is not the first time AI is being used to protect wildlife in India. In December, India's federal railway ministry said it was implementing an AI-based surveillance system - called Gajraj - in elephant corridors across several states in the country.
