[6] At approximately 17:40 on 13 November 2013, an Assam-bound passenger train travelling through the Chapramari Forest, Udaipur City–Kamakhya Kavi Guru Express (19709), approached the Jaldhaka River Bridge at ~80 km/h and collided with a herd of 40 to 50 elephants, killing five adults and two calves and injuring ten others.

[10][11] In an unrelated statement by West Bengal's forest minister, Hiten Burman, it was noted that official requests to a similar effect have been disregarded by railway authorities in the past.

[8] The crash reignited discussion over the history and administration of the 168 km track, which runs from New Jalpaiguri to Alipurduar and also passes through Buxa Tiger Reserve.

[1] Animesh Basu, a coordinator for the Himalayan Nature and Adventure Foundation, criticised the government's response to the issue of its national heritage animal being frequently hit by trains, highlighting the irony of Indian Railways' use of an elephant calf as its mascot.

[12] Electric fencing, stationary lighting, and motion sensors have each been proposed as technical measures to prevent similar incidents in the future.
