Mumbai-Ahmedabad Bullet Train Introduces Tunnel Hood Technology to Manage Pressure Waves
India's Mumbai-Ahmedabad Bullet Train project is introducing tunnel hood technology for the first time in the country to manage pressure waves and reduce noise as trains enter and exit mountain tunnels. Installed at both ends of eight tunnels across Maharashtra and Gujarat, these hoods feature pressure-relief vents that gradually release compressed air, minimizing tunnel boom and enhancing passenger comfort. This adoption aligns with international high-speed rail standards and aims to improve operational efficiency and environmental impact along the 508-km corridor.
