The Board has cited multiple curves along the route will not be suitable for a bullet train to run at 350 km per hour.
The feasibility study report was presented by the National High Speed Rail Corporation (NHSRCL).
The feasibility report proposed the corridor be built along the NH-2. It will help in the acquisition of land at cheaper rates and reducing the cost of construction.
However, NH-2 had curved sections at many places between Delhi and Varanasi would make it difficult for a train to run at 350 km per hour.
