Mumbai-Ahmedabad Bullet Train Introduces India's First Tunnel Hood Technology
India's Mumbai-Ahmedabad Bullet Train project is introducing tunnel hood technology for the first time in the country to enhance passenger comfort and reduce noise. Installed at both ends of eight mountain tunnels across Maharashtra and Gujarat, these structures manage pressure waves generated by trains traveling over 300 kmph. Tunnel hoods feature pressure-relief vents that allow gradual air release, minimizing tunnel boom and improving aerodynamic performance, while supporting safer and quieter high-speed rail operations.
