Railways in the Himalaya and the north-east run through young, fractured mountain geology, steep slopes and heavy rainfall.
Prof. (Dr.) H. R. Yadav's experience includes Himalayan NATM tunnel design on the USBRL and hill-terrain railway structures on Northeast Frontier Railway.
Engineering challenges
- Tunnelling in fractured, faulted rock
- Slope stability and drainage on hill sections
- Access and logistics in remote terrain
