Mumbai-Ahmedabad Bullet Train: Over 200,000 Noise Barriers Installed
Mumbai-Ahmedabad Bullet Train: Over 200,000 Noise Barriers Installed
Over 200,000 noise barriers have been installed along more than 100 km route of the Mumbai-Ahmedabad Bullet Train, as announced by the National High Speed Rail Corporation Ltd (NHSRCL). These barriers are engineered to minimize operational noise while maintaining the stunning views available from the train, ensuring passengers enjoy a smooth and scenic journey.
The noise barriers being installed along the Mumbai-Ahmedabad Bullet Train viaduct are based on advanced Shinkansen technology. These barriers consist of concrete panels, each 2 meters high and 1 meter wide, placed on both sides of the viaduct. The design is specifically done to address the unique challenges of high-speed rail operations.
The main purpose of these noise barriers is to lessen the sound produced by the train’s high-speed travel. As the bullet train moves, it generates aerodynamic noise due to its interaction with the air. Additionally, noise is created by the train’s wheels making contact with the tracks. The concrete panels are strategically placed to reflect and disperse these sounds, effectively reducing noise levels.
These barriers not only aim to decrease operational noise pollution but also ensure that the scenic views along the route remain unobstructed. By managing noise effectively while preserving the beautiful surroundings, the project strikes a careful balance between technological advancement and environmental awareness, providing a more comfortable and peaceful experience for passengers while minimizing disturbances for those living near the train route.
Improved noise barriers and train design will help reduce sound impact along the Mumbai-Ahmedabad High-Speed Rail. In residential and urban areas, the noise barriers will be taller, reaching 3 meters in height. These barriers will consist of a 2-meter concrete panel topped with an additional 1 meter of clear polycarbonate material.
The train is also engineered to minimize internal noise. Its structure is made from a double-skin aluminum alloy, which contributes to lowering the noise levels inside.
The train features a long, pointed nose designed to decrease aerodynamic drag, which in turn helps lessen the loud sounds generated by pressure waves when the train exits a tunnel.
Of the total 508 km length of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) line, more than 465 km will be elevated, running on viaducts.
