SURAT (Metro Rail News): TBM S78 or TBM Narmada of the Surat Metro recorded its first “Hidden” breakthrough at the Labheshwar Chowk station. 

Assignment 

The TBM completed a 1.5-kilometre-long drive from Kapodra Station’s western shaft to the unique 4-level Labheshwar Chowk Station’s box. It was on task to complete a down-line tunnel as its very first assignment. 

Further Plans 

Further, the excavation at Labheshwar Chowk Station will be taken up only after Narmada and sister machine TBM Tapi pass through. 

Labheshwar Chowk Station 

The Labheswar Chowk Station will be built 30 meters deep with two concourse levels & 2 platform levels. It will be 2nd deepest metro station in India after Howrah Metro station of Kolkata Metro’s East-West Corridor.

Further Scope of Work 

The construction project for Package CS2/UG1, spanning 3.46 km and awarded by Gujarat Metro Rail Corporation (GMRC) in March 2021, involves the creation of six tunnels by both S78 and S94 in Surat. Additionally, Gulermak – Sam India JV is tasked with building three stations at Kapodra, Labheshwar Chowk, and Central Warehouse as part of their scope of work.

Status of S-78 

TBM S94 lags behind S78, and both machines will eventually be recovered from the eastern shaft of Surat Railway Station
