MMRC completes 60% of Phase 1 track laying work on Mumbai Metro 3

2023-01-10

According to the Mumbai Metro Rail Corporation (MMRC), which is constructing this line, track laying work on the underground Mumbai Metro Line 3 (Colaba-Bandra-SEEPZ) is currently close to 60% complete.

Head Hardened (HH) rails, which can withstand approximately 50% more pressure than standard rails, were manufactured by a Japanese company and imported from Japan. For the first time in India, the Low Vibration Track (High Attenuation) technology is being used. These tracks will reduce the higher level of noise and vibration generated during train operations on this line, which is in the range of 22VdB (vibration measurement).

Recently MMRCL said that the first phase – Aarey to BKC – of the Colaba-Bandra-SEEPZ Metro-3 Corridor would be operationalised soon in 2023

According to MMRC, over 90% of the stations in Phase 1 are ready, and 55% of the system work is completed. The Metro 3 underground line has 26 stations in total, with nine underground stations in Phase 1. These stations are built at depths ranging from 20 to 29 metres.
