India's First Undersea Rail Tunnel Advances with Giant TBM Launch under Thane Creek
The Mumbai–Ahmedabad Bullet Train Project reached a milestone with the launch of a second Tunnel Boring Machine (TBM) to excavate India's first undersea rail tunnel under Thane Creek. The 7-km undersea stretch is part of a 21-km underground tunnel, with the new TBM starting from Sawli (Ghansoli) towards Vikhroli. The project promises faster connectivity and reduced surface disruption in the Mumbai suburban section.
