Metro rail connectivity between this city and the national capital may have provided relief for commuters, but the much admired public transport service is giving sleepless nights literally for many.
Residents living in colonies beside a small stretch of the metro track have been complaining of noise pollution due to frequent screech of train brakes at a sharp curve near Iffco Chowk metro station.
According to the residents of Pearl Court apartments in Essel Towers, despite assurance from the Delhi Metro Rail Corporation (DMRC) about putting greasing machine for lubricating the tracks, adequate measures are not taken to minimise the brake sound.
The DMRC also acknowledged that the curve with 282 metre radius from metro pillar no. 125 to 137 is sharper than the standard norm of 300 metre radius . It said the tracks had to be constructed within the limited space to save the nearby structures. Following complaints from the residents, the DMRC has increased the frequency of greasing of tracks at the affected site.
"We will be shortly installing an automatic lubricating machine as well. Further, the speed of trains has been reduced. If the situation does not change, other measures will be considered," DMRC chief E Sreedharan said in his e-mailed response to a RWA representative.
Meanwhile, the residents have threatened to move to court if the DMRC fails to install noise insulators as well as double or triple glaze glasses on their houses to minimise the impact of the disturbing sound.
As per the DMRC, at one of the hi-rise towers, the noise level varied between 73 and 74 decibels (Db) in the peak hours as against the prescribed norms of 45 and 55 Db.
