Seven elephants were killed and one was critically injured on the night of December 17, 2025, when a passenger train struck a herd while it was crossing the railway tracks in the Hojai district of Assam. The incident occurred in a known elephant corridor that intersects the railway line, highlighting the recurring and deadly conflict between railway infrastructure and wildlife movement in northeast India. Assam is home to approximately 5,700 Asian elephants — nearly 22% of India's entire elephant population — and the state has reported multiple train-elephant collision deaths over the past decade. Wildlife conservationists and the Wildlife Crime Control Bureau have repeatedly flagged that railway lines bisecting elephant corridors in Assam, West Bengal, and Odisha represent one of the gravest threats to elephant survival in India. Key demands include mandatory speed restrictions on trains passing through elephant corridors at night, real-time monitoring systems, improved coordination between the Forest Department and Indian Railways, and construction of underpasses and overpasses to allow safe elephant movement. India is a signatory to the 'Gaj Yatra' elephant conservation initiative and has designated several Elephant Reserves across the country, but ground-level implementation of protective measures remains critically inadequate. The incident renewed calls for urgent action under Project Elephant, launched in 1992, to address the human-elephant conflict and infrastructure encroachment on traditional wildlife corridors.
