The much-anticipated bullet train project is set to commence on August 15, 2027. After more than four years of delay, the project is finally moving forward with technical and financial support from the Japanese government. Initially estimated at ₹1.1 lakh crore, the project's cost has escalated by 83%, bringing the total to ₹1.98 lakh crore.
Construction begins in Palghar district, and the full 508 km corridor between Mumbai and Ahmedabad is expected to be completed by December 2029. The high-speed rail will pass through Maharashtra, Gujarat, and Dadra & Nagar Haveli, running at speeds of 320 kmph and completing the journey in approximately 2 hours and 17 minutes.
The project recently achieved a major milestone with the breakthrough of the tunnel in Palghar district, Maharashtra. A total of eight mountain tunnels are under construction - seven in Maharashtra and one in Gujarat. The longest tunnel in Palghar, measuring around 1.5 km, lies between Virar and Boisar stations. In comparison, another 5 km tunnel is being constructed underground between Thane and BKC, which was completed in September 2025.
