It will expedite a high-speed railway, as is that the proven technology in metro and similar projects. Work has already begun on 325 KM out of the 508 KM corridor between Mumbai & Ahmedabad. More than 97% of the land has been acquired for the project in Gujarat, Dadra & Nagar Haveli, and 30% of the project will improve skillset in various rail construction technologies.
