India’s first undersea rail tunnel is part of the bullet train project - here’s everything else that’s extraordinary

India’s first bullet train project connecting Mumbai and Ahmedabad features a 21-km tunnel, including a 7-km undersea stretch. The corridor uses Japan’s Shinkansen technology for a 320 kmph speed. It includes earthquake detection systems and 12 modern stations. This ambitious project ensures safer, faster travel between the two major Indian cities.
