India's Long-Awaited Khurda-Balangir Railway Line Set for Final Completion
The Khurda Road-Balangir railway line, a monumental 301-kilometer project first conceived even before India gained independence, is finally approaching its full operational status, with completion targeted for early next year. This initiative stands as one of the nation's oldest pending railway endeavors, weaving through five districts of Odisha—Khurda, Nayagarh, Boudh, Sonepur, and Balangir—and already bringing rail connectivity to three of these regions.
Engineering Excellence Meets Environmental Stewardship
Hailed as an engineering marvel, this railway line exemplifies a profound commitment to environmental safeguards. A significant 75-kilometer segment between Daspalla in Nayagarh district and Purunakatak in Boudh district traverses alongside the Baisipalli Wildlife Sanctuary, an integral component of the Satkosia Tiger Reserve, and skirts a proposed Brutang irrigation project in Nayagarh.
To mitigate habitat fragmentation and reduce human-animal conflicts in these dense forests, the railways have constructed seven tunnels spanning 12.76 kilometers, alongside numerous wildlife underpasses and overpasses. The project's crowning engineering achievement is a viaduct stretching 4.77 kilometers, with piers soaring to heights of 26 meters. Upon commissioning, it will rank as the second-longest viaduct in the Indian Railways network, following the Bogibeel bridge in Assam.
Protecting Wildlife and Preserving Ecosystems
This viaduct doubles as a wildlife underpass, specifically designed to facilitate the unobstructed movement of elephants—a critical feature in Odisha, which reports an average of 85 elephant fatalities annually. Beyond elephant-specific passages, the entire project, constructed at an approximate cost of Rs 5,000 crore, incorporates dedicated wildlife corridors and systems developed in consultation with the forest department to ensure the free movement of elephants and other wild animals. Post-construction, many tunnel roofs will be transformed into grazing grounds.
According to the East Coast Railway (ECoR), the project area serves as a vital corridor for Odisha's elephant population. "Strategically placed underpasses and elevated viaducts allow animals to move freely without risking track collisions," a railway official emphasized. Between Mahipur station in Nayagarh and Jhatarabha station in Subarnapur, there are 12 elephant/wildlife underpasses and six overpasses, predominantly located in the Daspalla and Purunakatak sections.
Official sources highlighted the ecological significance: "Elephants are landscape animals and keystone species that maintain ecological balance over vast areas. They transform forests, create water sources, and disperse seeds, supporting biodiversity. The construction of viaducts and elephant passes ensures forest reserves and the sensitive ecological balance evolved over millions of years are not destroyed by human activities."
Eco-Friendly Construction Practices
To minimize environmental impact, ECoR adopted eco-friendly construction methodologies. "The use of high-rise viaducts instead of massive embankments saved approximately two lakh trees from being felled. Because of the viaducts, we conserved a substantial amount of soil that would have been used for earthwork between Buguda and Banigochha stations," the railway officer added.
Current Operations and Regional Impact
Presently, train services are operational on a 226-kilometer stretch of the new line, from Khurda Road to Daspalla and from Balangir to Purunakatak via Sonepur, covering 20 stations. With four trains running between Khurda Road and Daspalla and three between Balangir and Purunakatak, approximately 5,000 passengers travel on this route daily on average.
The project has already revolutionized connectivity for three districts: Nayagarh, which gained rail access for the first time post-independence in 2017; Sonepur, connected in 2024; and Boudh, linked last year.
A Vision of Transformative Connectivity
ECoR's General Manager Parmeshwar Funkwal remarked, "The Khurda-Balangir railway line stands as an engineering marvel that balances technological excellence with ecological responsibility. Executed through challenging forested and hilly terrain, the project incorporates tunnels, major bridges in sensitive stretches, dedicated elephant passages, and scientifically designed viaducts to protect wildlife corridors, natural water flow, and ecosystems. It reflects our commitment to delivering transformative connectivity while upholding the highest environmental safeguards under Indian Railways."
