Bullet train project: 2 lakh noise barriers installed along the 100-km viaduct

The MumbaiAhmedabad bullet train project has reached a significant engineering breakthrough with the installation of 206000 noise barriers along its 103 km viaduct corridor NHSRCL said in an official statement on MondayThe project has strategically placed 2000 noise barriers on each side of every kilometer of track demonstrating remarkable precision in acoustic engineering stated National High Speed Rail Corporation NHSRCLThese sophisticated noise barriers are meticulously designed to mitigate sound generated during train operations Measuring two metres in height and one metre in width each barrier weighs approximately 830840 kg and is engineered to reflect and distribute aerodynamic noise produced by train movementOver 200000 noise barriers installed along 100 km of MumbaiAhmedabad Bullet Train viaduct to mitigate noise during operations without obstructing scenic view from the train pictwittercomQRWQYUDBB4mdash NHSRCL nhsrcl December 23 2024Over 200000 noise barriers installed along 100 km of MumbaiAhmedabad Bullet Train viaduct to mitigate noise during operations without obstructing scenic view from the train NHSRCL said in a post on XIn residential and urban areas the project has implemented enhanced threemetre tall barriers featuring an additional 1metre translucent polycarbonate panel ensuring passengers maintain unobstructed scenic views while minimizing environmental noiseTo support this massive production requirement six dedicated manufacturing facilities have been established across Gujarat with three located in Ahmedabad and one each in Surat Vadodara and AnandThis strategic infrastructure development has not only facilitated barrier production but also created significant local employment opportunities NHSRCL saidThe projects construction progress extends beyond noise barriers NHSRCL stated that over 243 km of viaduct construction has been completed accompanied by 352 km of pier work and 362 km of pier foundation workThe project has already constructed bridges across 13 rivers and successfully crossed multiple railway lines and highways using five steel bridges and two PSC bridgesTrack construction in Gujarat is advancing rapidly with Reinforced Concrete RC Track Bed construction underway in multiple districts including Anand Vadodara Surat and NavsariSeventyone track kilometers of RC track bed have been completed with rail welding already commenced on the viaductIn Maharashtra significant milestones have been achieved including casting the first concrete baseslab for the Mumbai bullet train station at an impressive depth of 32 metresThe 21 km tunnel between BandraKurla Complex and Shilphata is progressing with a 394metre Intermediate Tunnel ADIT already completed to facilitate main tunnel constructionThe project is simultaneously constructing seven mountain tunnels in Palghar district using the New Austrian Tunnelling Method NATM with the mountain tunnel in Gujarat already successfully completedTwelve stations along the corridor are being developed with innovative thematic elements and energyefficient features promising a worldclass passenger experienceldquoThe MumbaiAhmedabad Bullet Train Project continues to set new benchmarks in highspeed rail infrastructure by combining cuttingedge technology with environmental considerations The project is not only transforming connectivity but also creating significant social and economic benefits including the generation of thousands of jobs the development of local industries and improvements in regional infrastructure It will also help in reducing travel time enhancing mobility and fostering regional development The project is set to drive economic growth and elevate the quality of life across Gujarat and Maharashtrardquo said Vivek Kumar Gupta Managing Director NHSRCL
