In the wake of the worsening air quality in the Mumbai region, three city stations—Ghatkopar, Khar and Kandivli—where infrastructure upgrade work is underway have got green net cover. Mumbai Railway Vikas Corporation (MRVC) which is handling these three key projects said on Thursday that special measures have been taken not just for Mumbai, but also for all other projects across the MMR. The green net, which is technically called scaffolding netting cloth, is used at construction sites, as these nets help in controlling the spillage of debris and the spreading of dust.
