MMRCL completes 18% of track laying work


MUMBAI (Metro Rail News): The Mumbai Metro Rail Corporation Ltd (MMRCL), the project implementing authority for the underground Metro Line 3 (Colaba-Bandra—SEEPZ), stated that overall 18% of track laying work has been achieved far.  On the entire corridor, a total of 66.07 kilometres of the track will be laid.

The Head Hardened (HH) rails of a total of 10,740 tonnes manufactured by Japanese company M/s. Nippon will be utilised for Metro-3 track work.  Last year, M/s. Mitsui imported all of the rails from Japan in three lots. M/s Larsen & Toubro has been commissioned with the track installation and construction.

For the first time in India, Low Vibration Track (High Attenuation) technology is employed for track work. M/s Sonneville AG, a Swiss company, devised this device to reduce greater levels of noise and vibration in the range of 22VdB (vibration measurement) generated during train operations on this line.

Because Metro Line 3 will travel beneath different heritage and ancient residential structures once it is completed. This technology will improve passenger comfort while also protecting the existing heritage structures on the ground.

The sleepers for the tracks are made in a specialised sleeper casting plant at Wadala explicitly built for this purpose. According to the MMRC, 201,600 sleeper blocks will be required for the entire project.

While overall, work on Metro Line 3 has been 71 per cent so far. A total of 97 per cent of the tunnelling work has been finished. The construction of the station is in full swing, with 77 per cent of the work completed thus far. According to the MMRCl, 34% of system development has been performed.

  1. Great work. Let’s hope that Aarey depot location is acceptable to a few NGOs and these NGOs allow our commute to happen.
