In India, the railways offer more than just transportation for human passengers; they have become an unexpected transit route for wildlife. Recent research indicates that king cobras (Ophiophagus kaalinga) may sometimes find their way onto trains, particularly in western regions like Goa, a state celebrated for its stunning beaches.
A study published in Biotropica by Dikansh S. Parmar and his team analyzed two decades of snake rescue data and local observations. They found that while most king cobras appeared in their expected habitats--lush, forested areas of the Western Ghats--there were notable exceptions.
Five unusual cases involved king cobras spotted in locations deemed unsuitable by their species-distribution model, all situated near railway infrastructure.
One such incident occurred at Chandor railway station, where a king cobra was discovered hiding among stored rails. Other sightings were reported near stations in Vasco da Gama, Loliem, Patnem, and Palolem--all areas not typically associated with these forest-dwelling snakes.
The prevailing theory suggests that these snakes may inadvertently travel long distances on freight trains, which pass through their natural habitats before reaching drier regions. Rail yards provide ample cover and a food supply, making it feasible for a large reptile to board a train at night and emerge in unfamiliar territory.
Documented instances of snakes on trains, including cobras, highlight this fascinating phenomenon. One striking photograph captures an Indian cobra peeking from a train window, illustrating the curious intersection of wildlife and rail travel.
While this unexpected journey may seem benign, it poses risks for both the snakes and humans. For the cobras, arrival in unsuitable environments can lead to stress and potential starvation. For people, encountering a king cobra in unexpected places can be hazardous, as bites from these snakes can be life-threatening, with no specific antivenom available in India.
The researchers advocate for further investigation, suggesting genetic testing and monitoring of railway hubs to better understand this intriguing pattern of travel.
Rather than merely fragmenting habitats, railway infrastructure may also be inadvertently connecting them in surprising ways.
