In a landmark achievement for Indian infrastructure, Larsen & Toubro (L&T) has set a new world record in tunnel construction for the prestigious Rishikesh–Karnaprayag Rail Link Project, a vital rail corridor through the Himalayas. The feat was accomplished on June 29, a day ahead of its baseline schedule, using advanced tunnel boring technology.
The Rishikesh-Karnaprayag Rail Line, a 125-kilometre route being developed by Indian Railways, is one of the most ambitious railway infrastructure projects in the country. Traversing the rugged terrain of Uttarakhand, the line aims to improve connectivity to the Char Dham pilgrimage circuit and significantly reduce travel time to the upper Himalayan region.
Among the most technically challenging parts of the project are the numerous tunnels — with nearly 85% of the route passing through mountainous terrain.
On June 29, L&T achieved a world record in tunnel construction using a single-shield hard rock tunnel boring machine (TBM) — a technology specifically suited for high-pressure, mountainous conditions. This milestone was marked by breakthrough precision, speed, and safety, all while working under difficult geological environments.
The record showcases India’s growing capabilities in complex infrastructure execution and reaffirms L&T’s position as a global engineering powerhouse.
The entire rail link project is expected to be completed by end-2026, and once operational, it will not only boost tourism but also enhance strategic and economic access to India’s northern frontier.
Speaking on the achievement, an L&T spokesperson said,
“Breaking this world record is not just a win for L&T, but for India’s vision of modern and resilient infrastructure. We’re proud to contribute to a project that will redefine Himalayan rail travel.”
This achievement is a significant step forward for sustainable development in India’s hilly terrains. It highlights how engineering innovation and national ambition can come together to overcome nature’s toughest challenges.
