India’s first high-speed rail project between Mumbai and Ahmedabad has achieved significant engineering milestones, with nearly 60 per cent of the viaduct already constructed and multiple critical segments underway across Gujarat, Dadra and Nagar Haveli, and Maharashtra.
The 508 km-long corridor—352 km in Gujarat and Dadra & Nagar Haveli and 156 km in Maharashtra—will feature 12 stations, connecting major nodes including Mumbai, Thane, Surat, Vadodara, and Ahmedabad.

Progress of around 143 km of track bed construction has been achieved so far in Gujarat.
3 lakh noise barriers have been installed over 150 km.
Rail welding work for 200-meter-long track panels is in progress.
Over 100 overhead equipment masts (OHE) have been installed between Surat and Bilimora bullet train stations.
Additionally, six of the eight stations in Gujarat have completed their structural work.
In Maharashtra, focus has shifted to complex tunneling and underground station development:
The 21 km tunnel between BKC and Shilphata has achieved 3.3 km of cumulative tunnel heading using the New Austrian Tunneling Method (NATM).
Seven mountain tunnels are also being executed in Palghar district.
Vikhroli and Sawli shafts have reached the required depths of 56 and 39 meters respectively.
At Mumbai Bullet Train Station, major excavation and foundation work is ongoing:
75 per cent of the total 18.7 lakh cubic meter earthwork is completed.
25,000 cu.m. concrete has already been poured for the base slab out of the planned 2 lakh cu.m., using temperature-controlled concrete from in-situ batching and chiller plants.
Secant piling work (3384 piles) is fully completed.
