India and Japan have decided to accelerate the launch of the country's first bullet train corridor by beginning operations with an indigenous high-speed train before Japan's next-generation E10 Series Shinkansen is ready. The move reflects the two nations' shared commitment to ensuring that the Mumbai-Ahmedabad High-Speed Rail (MAHSR) project becomes operational at the earliest, even as construction continues at a rapid pace.
Under the agreement, Japan will supply its next-generation E10 Series Shinkansen trains in the early 2030s after the model, which is currently under development, is ready for commercial deployment. Until then, the initial operational section of the corridor will use an Indian high-speed train, allowing passenger services to commence without waiting for the arrival of the new Japanese rolling stock.
The decision is aimed at avoiding delays in India's maiden high-speed rail service while maintaining the long-term plan of operating the advanced E10 Series trains once they become available. It also highlights the strong strategic and technological partnership between India and Japan in the field of modern railway infrastructure.
Union Railway Minister Ashwini Vaishnaw has announced that the first phase of the Mumbai-Ahmedabad bullet train project will be inaugurated on August 15, 2027. The inaugural section will connect Surat and Bilimora in Gujarat, marking the beginning of India's high-speed rail era.
Speaking at the HYSEA GCCS & IT Roundtable held at the Novotel Hyderabad Convention Centre, Vaishnaw said the 508-km corridor would be commissioned in phases. After the Surat-Bilimora stretch, operations will gradually be extended to Vapi, Ahmedabad, Thane, and eventually the entire Mumbai-Ahmedabad route.
According to the Railway Minister, nearly 80 per cent of the project has already been completed, and work is progressing in line with the planned schedule. Once the full corridor is operational, trains are expected to achieve speeds of up to 320 kilometres per hour, dramatically reducing travel time between Mumbai and Ahmedabad.
The Mumbai-Ahmedabad High-Speed Rail corridor is India's first bullet train project and spans 508 kilometres. Built using Japan's globally acclaimed Shinkansen technology, the corridor is expected to cut travel time between the two financial hubs to approximately 2 hours and 7 minutes, compared to the current travel duration of several hours by conventional rail.
The project is also expected to transform inter-city transportation by offering faster, safer and more efficient travel, while boosting economic activity, business connectivity and regional development along the route.
While Japan's E10 Series Shinkansen will eventually become the flagship train for the corridor, the interim use of an Indian high-speed train demonstrates India's growing capabilities in railway technology and its determination to meet project timelines.
The phased operational strategy ensures that infrastructure already nearing completion can be put to use without waiting for the next-generation Japanese trainset. Once the E10 Series enters service in the early 2030s, it will replace or complement the interim Indian trains on the corridor.
The Mumbai-Ahmedabad High-Speed Rail project is largely funded through an Official Development Assistance (ODA) loan from the Japan International Cooperation Agency (JICA), which has played a crucial role in supporting the ambitious infrastructure initiative.
However, officials have clarified that the project's additional cost escalation—estimated at nearly Rs 90,000 crore—will be fully borne by Indian Railways through gross budgetary support, with no proposal to seek additional financial assistance from Japan.
As construction gathers momentum and operational milestones draw closer, the India-Japan collaboration on the bullet train project is entering a decisive phase. With the first services scheduled for Independence Day 2027, the project is poised to usher in a new chapter in India's transportation history while laying the foundation for a nationwide high-speed rail network in the years ahead.
