Mumbai: The ambitious Mumbai-Ahmedabad High-Speed Rail (MAHSR) project has marked a significant milestone with the installation of over 175,000 noise barriers along the Gujarat segment of the corridor. This development underscores the project’s commitment to minimising environmental and residential impact as the bullet train project progresses towards completion.
The installation of these noise barriers is a key component of the ongoing construction, which currently spans 87.5 kilometres of the viaduct. Work is actively progressing in both the Gujarat and Maharashtra sections, reflecting substantial advancement in India’s inaugural bullet train venture. According to officials from the National High Speed Rail Corporation (NHSRCL), the noise barriers are engineered to address both train-generated and structural noise. Each barrier stands 2 meters high and 1 meter wide, with individual panels weighing between 830 and 840 kilograms. These barriers are designed to mitigate aerodynamic noise and reduce the impact of wheel-on-track noise.
In densely populated areas, the barriers will extend to 3 meters in height, with the upper meter constructed from translucent polycarbonate. This design not only helps in noise suppression but also allows passengers to enjoy unobstructed views of the landscape. To support the manufacturing and installation of these barriers, six precast factories have been established across Gujarat. Three are located in Ahmedabad, with additional facilities in Surat, Vadodara, and Anand. This infrastructure enables efficient production of modular units, which are being installed at an impressive rate of 2,000 barriers per kilometer of viaduct. The installation of noise barriers is a crucial step in the development of the MAHSR corridor, aiming to ensure that the high-speed rail project delivers both operational efficiency and environmental sensitivity. As the project progresses, these barriers will play a vital role in enhancing the quality of life for residents and ensuring a quieter journey for passengers.
