Ahmedabad Bullet Train Project Sound Barriers Operated to Reduce Noise

In a significant development, the National High Speed ​​Rail Corporation Limited which is overseeing the ambitious Mumbai-Ahmedabad Bullet Train Project on Tuesday said that work is underway to install sound barriers on the Mumbai-Ahmedabad Bullet Train Corridor. These sound barriers are installed to reduce the noise generated by the train and civil structure during operation. A press release from NHSRCL said that as of September 10, noise barriers have been installed in an area of ​​87.5 km and more than 1,75,000 noise barriers have been installed in Gujarat. According to NHSRCL, about 2000 sound barriers have been installed on either side of the viaduct for an area of ​​1 km.

2000 noise barriers have been installed on either side of the viaduct for an area of ​​1 km. Three precast factories have been set up for this modular element in Surat Anand and Ahmedabad for manufacturing the noise barriers, the press release said. The noise barriers are concrete panels 2 m high and 1 m wide from the rail level. Each noise barrier weighs around 830-840 kg. They will reflect and distribute the aerodynamic sound generated by the train and the lower part of the train mainly the sound generated by the wheels running on the tracks, NHRSCL said. These are designed in such a way that they will not obstruct the view of the passengers enjoying the train ride, the release said. The viaducts passing through residential and urban areas will have 3 m high/high noise barriers. Apart from the 2 m concrete panel, the additional 1 m noise barrier will be of 'polycarbonate' and translucent in nature. Earlier on July 31, Minister of Railways, Information and Broadcasting and Electronics and Information Technology Ashwini Vaishnaw told the Lok Sabha in a written reply to a question that the entire land - 1389.5 hectares - has been acquired for the Mumbai - Ahmedabad bullet train project. It is written in the reply, so far 350 km of pier foundation, 316 km of pier construction, 221 km of girder casting and 190 km of girder launching work has been completed. Work on about 21 km long undersea tunnel has also started.
