Mumbai-Ahmedabad Bullet Train: Full Corridor Completion by 2029
The dream of high-speed rail travel in India is rapidly approaching reality as construction on the Mumbai-Ahmedabad bullet train project hits significant milestones. The National High-Speed Rail Corporation Limited (NHSRCL) has reported a massive surge in progress, signaling that the corridor is moving steadily toward its completion targets.
Massive Progress and Technical Milestones
As of late July 2026, construction work on the high-speed line has reached 62.16% completion. When including land acquisition, the overall project progress has exceeded 80%. This state-of-the-art corridor is designed to operate at speeds of up to 320 kilometers per hour, utilizing cutting-edge Japanese Shinkansen technology.
The technical specifications of the line include:
- A 1,435 mm rail gauge for high-speed stability.
- A 25 kV AC electrification system.
- Extensive infrastructure including 456 kilometers of piers and 371 kilometers of viaducts.
- The installation of 9,300 overhead equipment masts.
Key Infrastructure Achievements
Significant engineering feats have been accomplished in recent months. On October 4, 2026, a massive 480-meter-long and 36-meter-high bridge over the Sabarmati River was successfully completed. Additionally, by October 12, 2026, all 14 portal beams were installed on the Delhi-Mumbai main line in Vadodara.
Subterranean work is also advancing, with four mountain tunnels already excavated and 5 kilometers of NATM tunnel work finished. While civil works are already complete at eight stations, teams are now shifting their focus to the intricate architectural finishing stages.
"BEML Limited secured a ₹5,400 crore contract—the largest in its history—to supply and maintain 16 high-speed trains for the project."
Timeline for Operations
The project, which is supported by Official Development Assistance (ODA) from the Japan International Cooperation Agency (JICA), has a clear roadmap for commuters. Passengers will first experience the high-speed technology on a 50-kilometer stretch between Surat and Bilimora, which is scheduled to open by August 15, 2027.
Following the initial phase, the entire 508-kilometer corridor is expected to be fully operational by 2029, fundamentally changing the landscape of travel between Mumbai and Ahmedabad.
