India’s bullet train project has achieved a major milestone with the successful opening of the first section of the 21-km undersea tunnel between Bandra-Kurla Complex (BKC) and Thane. This tunnel is part of the ambitious Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor and marks a significant step forward in India’s journey towards high-speed rail connectivity.
The project has also achieved the completion of 310 km of viaduct construction across the 508-km-long corridor. Construction activities such as track laying, installation of overhead electrical wires, and building of stations and bridges are progressing rapidly. In Maharashtra, the pace of work has picked up significantly, further accelerating the overall development of the project.
One of the most striking features of the project is the BKC bullet train station, which is being built 32.5 metres below ground. This station is considered an engineering marvel, with its foundation designed to support a 95-metre-high commercial building above ground.
Precision and progress towards #BulletTrain ! 🚅

Another major highlight is the introduction of next-generation E10 Shinkansen trains. As part of the strategic partnership between India and Japan, these state-of-the-art trains will be introduced simultaneously in both countries. Currently, Japan operates E5 Shinkansen trains, and the E10 models represent a significant upgrade in terms of speed, safety, and technology.
The entire corridor is being developed using Japanese Shinkansen technology, known for its unmatched performance in high-speed rail systems. This reflects the deep technological and strategic cooperation between India and Japan and sets new benchmarks in rail infrastructure.
So far, 15 river bridges have been completed, and four more are in the final stages of construction. Out of the 12 planned stations, five are complete, while three more are nearing completion.
The successful progress of the MAHSR project is laying a strong foundation for future bullet train corridors in India. Several new routes are already under active consideration.
This remarkable pace of development highlights India’s growing capability to execute world-class infrastructure projects using cutting-edge global technology, with Japan playing a vital role as a trusted partner in this transformative journey.
