The Mumbai-Ahmedabad Bullet Train Project achieved a major milestone with the successful breakthrough of the second mountain tunnel in Palghar, Maharashtra on 3 Feb 2026. This tunnel is 454 metres long with a width of 14.4 metres, and will accommodate both up and down tracks for the Mumbai-Ahmedabad Bullet Train project.
The mountain tunnel (MT-6) was excavated from both ends using New Austrian Tunnelling Method (NATM), a cutting-edge drill-and-controlled blast method. The excavation is completed within 12 months.
As per the Release,Union Minister Ashwini Vaishnaw congratulated the entire high-speed rail team for their remarkable progress. He said the pace at which the team is working has instilled new confidence in the country. The project is drawing global attention and appreciation due to several new innovations in construction and technology. He highlighted that many advanced construction technologies and large machines being used for the project are manufactured in India.
In Maharashtra, construction work is advancing rapidly across multiple sites. Currently, seven mountain tunnels are currently underway in Palghar district. The current status of the tunnel have been mentioned below:
| Sr. No | Mountain Tunnel No. | Length | % Completion | Remarks |
| 1 | MT-1 | 0.820 | 16% | |
| 2 | MT-2 | 0.228 | Preparatory works underway | |
| 3 | MT-3 | 1.403 | 41% | |
| 4 | MT-4 | 1.260 | 32% | |
| 5 | MT-5 | 1.480 | 57% | Breakthrough achieved on 02 Jan 2026 |
| 6 | MT-6 | 0.454 | 47% | Breakthrough achieved today |
| 7 | MT-7 | 0.417 | 29% |
