Summary
Approximately 83% of the line, about 104 kilometres, will run through tunnels, requiring 16 tunnels and 19 bridges to navigate the complex geology of soft mountain strata.
The railway will improve travel to pilgrimage sites such as Kedarnath and Badrinath and is considered strategically important because the terminal station lies close to the India‑China border.
India is now designing and manufacturing its own large‑diameter Tunnel Boring Machines, reducing reliance on imports and supporting many national projects.
