India installs tunnel hoods on Mumbai‑Ahmedabad bullet train to cut noise

The Mumbai‑Ahmedabad high‑speed rail project has added tunnel hoods along its route. Tunnel hoods are aerodynamic structures that smooth airflow in tunnels. Their installation aims to reduce pressure waves that generate noise. Engineers say the modification will improve passenger comfort on the line. The hoods also help protect the train’s exterior from wear caused by rapid air movement. Construction crews completed the fittings ahead of the scheduled launch. Officials expect quieter journeys to increase public acceptance of the service. The project remains on track for commercial operation later this year.
