Bullet train project: India installs tunnel hoods – how they keep your journey smooth

India’s ambitious Mumbai-Ahmedabad Bullet Train project is introducing tunnel hood technology for the first time, enhancing high-speed rail travel. This innovation manages air pressure changes in mountain tunnels, significantly reducing noise and ensuring smoother, quieter journeys for passengers and surrounding communities. The technology employs pressure-relief vents to gradually equalize air, mirroring global best practices for advanced rail infrastructure.
