MUMBAI (Metro Rail News): Mumbai Metro Rail Corporation (MMRC) has now achieved the 40th breakthrough at Mahalaxmi Metro Station out of the total 42 breakthroughs planned for the 33.5 km long Colaba-Bandra-Seepz underground line (Line-3) of Mumbai Metro.
The Robbins Company made TBM (Tunnel Boring Machine), named Tansa-1, operated by Doğuş and Soma JV has completed a downline drive of 1135.5 meters from Science Museum Metro Station to Mahalaxmi Metro Station. TBM Tansa-1 took 325 days using 757 concrete rings to finish the breakthrough.
Package-3 (Mumbai Central–Worli) includes five stations namely – Mumbai Central, Mahalaxmi, Science Museum, Acharya Atre Chowk and Worli Metro stations. It is the longest stretch of the corridor and has now witnessed total four breakthroughs out of six breakthroughs planned under this package. The four breakthroughs which are completed are – (Science Museum to Worli – upline-2072m and downline-2057m) and (Science Museum to Mahalaxmi – upline-1117.5m and downline-1135.5m).
Two more breakthroughs are remaining, both under Package-3, finishing of these breakthroughs will mark the completion of the tunnelling work on this 33.5 km long fully underground line with 27 stations on the route.
“We have now completed twin tunnels beneath the western railway track between Mahalaxmi and Lower Parel Station. Also, the tunnels are in close proximity of 17m deep MCGM underground sewer pumping station at Jacob Circle. I must say, our team has accomplished this daunting task skilfully”, said Mr. Ranjit Singh Deol, Managing Director, MMRC.
With this breakthrough, the overall tunnelling completed on the project is 53 km out of the total 54.50 km double line which is approximately 97% of the total project.
