NEW DELHI (Metro Rail News): The ever-expanding Delhi Metro Rail Corporation (DMRC) has been plagued with a new problem regarding vibrations and noise caused due to its train movements.
To address the problem, the corporation is preparing guidelines to mitigate noise levels at its elevated stations and testing new technology to reduce vibration at its underground ones.
The DMRC has roped in the Central Road Research Institute (CSIR-CRRI) to prepare guidelines for measures to be taken along elevated corridors to ensure noise levels are within permissible limits.
Anuj Dayal, executive director of corporate communications at DMRC, said, “We have received complaints from various places regarding noise along our elevated corridors. We had asked CRRI to prepare guidelines about three months ago, as there is are no such guidelines available worldwide, specifically for Metro systems. Wherever there is a need, we are retrofitting the tracks to minimize noise and vibration levels.”
The guidelines will provide parameters for installing noise barriers depending on noise level, location of the station and distance of the buildings in the vicinity. There are 181 elevated stations in Delhi, with the Metro cutting through residential areas such as Karol Bagh, East of Kailash and Mayur Vihar.
With 68 underground stations, mostly in the south and central Delhi, DMRC has been receiving several complaints regarding vibrations.
Residents of Saket, Hauz Khas, Begumpur, Shahbad Mohammadpur, Sarvpriya Vihar have complained that they feel the vibration every time a train passes in the tunnel.
With four Metro corridors — Yellow line (HUDA city centre-Samaypur Badli), Blue Line (Dwarka Sector 21-Noida City Centre), Violet line (Kashmere Gate-Raja Nahar Singh) and Airport express line — passing through central Delhi, residents of Luytens’ Delhi too have complained about vibrations and rumbling noises inside their bungalows.
Earlier this year, BJP leader and former Mp, Murli Manohar Joshi, had complained to DMRC in this regard. “We could hear the sound of trains passing underneath the house. DMRC, however, was prompt to address the issue. Though the problem is still there, it has reduced substantially,” said Rajiv Belwal, personal secretary to Joshi.
