Mumbai-Ahmedabad Bullet Train: Over 2 Lakh Noise Barriers Installed Along 100+ Km For A Quiet, Scenic Journey

The National High-Speed Rail Corporation Ltd (NHSRCL) announced the installation of over 2 lakh noise barriers along a 100+ km stretch of the Mumbai-Ahmedabad Bullet Train corridor.

These barriers, designed using advanced Shinkansen technology, aim to reduce operational noise while preserving the scenic experience for passengers.

The noise barriers consist of 2-meter-high and 1-meter-wide concrete panels placed on both sides of the viaduct. Their primary purpose is to mitigate sound generated by the high-speed train’s operations.

Aerodynamic noise, created by the interaction between the train and the air, and the sound from wheels making contact with the tracks, are effectively reduced by these strategically positioned barriers.

In urban and residential areas, the barriers are taller, with a 3-meter height that includes a 2-meter concrete panel and an additional 1-meter section made from clear polycarbonate material. This design ensures reduced noise pollution while maintaining uninterrupted scenic views along the route.

“These noise barriers not only aim to reduce operational sound pollution but also ensure that the scenic views along the route remain uninterrupted,” NHSRCL stated.

“By effectively managing the noise without obstructing the beautiful surroundings, the project demonstrates a careful balance between technological innovation and environmental consideration.”

The bullet train itself is engineered to further minimize noise. Its body is constructed from double-skin aluminium alloy, reducing interior noise levels. Additionally, the train’s long, sharp nose is designed to reduce aerodynamic drag and loud pressure waves when exiting tunnels.

The Mumbai-Ahmedabad High-Speed Rail (MAHSR) line spans 508 km, of which over 465 km will be elevated on viaducts. The project showcases a focus on both passenger comfort and minimising disturbances for residents near the train route.
