**Summary:**
The Ministry of Railways announced a significant milestone in the Mumbai-Ahmedabad High-Speed Rail (MAHSR) project (Bullet Train project) with the opening of the first section of the 21 km undersea tunnel between Ghansoli and Shilphata in Maharashtra. This announcement, dated July 14, 2025, also highlights the planned introduction of the next-generation E10 Shinkansen trains, a product of the India-Japan partnership, which will debut simultaneously in both countries. The entire 508 km corridor is being developed using Japanese Shinkansen technology, aiming to establish new standards for speed, safety, and reliability.
Construction is progressing rapidly, with 310 km of viaduct already completed. Fifteen river bridges are finished, and four are in advanced construction stages. Out of the 12 stations planned, five are complete, and three are nearing completion. The Bandra Kurla Complex (BKC) station is notable for its underground construction (32.5 m below ground) and foundation designed to support a 95 m high building above. Procurement of systems for operations and control is also advancing well.
The successful execution of the MAHSR project is paving the way for future bullet train corridors in India, which are currently under active consideration. The project exemplifies India's capacity to execute world-class infrastructure with cutting-edge global technology, with Japan as a key partner.

The bullet train project has achieved a major milestone of opening the first section of the 21 km
undersea tunnel between BKC and Thane. The bullet train project recently achieved a major
milestone by completing 310 km of viaduct construction. Track laying, construction of overhead
electrical wires, stations, and bridges is going on at a rapid pace. The construction work in
Maharashtra has also picked up pace. In parallel, the progress on procurement of systems for
operations and control is also going on well.Rolling Stock: Japanese Shinkansen is currently running E5 trains. Next generation trains are E10. In the
spirit of strategic partnership between Japan and India, the Japanese government has agreed to introduce E10
Shinkansen trains in the Mumbai-Ahmedabad Bullet train project. It is noteworthy that E10 will be
introduced simultaneously in India and Japan.Japanese Technology: The entire 508 km corridor is being developed with Japanese Shinkansen
technology. It will set new benchmarks for speed, safety, and reliability. This reflects the deep
strategic and technological cooperation between India and Japan.
Construction at Rapid Pace: Civil works are progressing at a rapid pace across the alignment. 310 km
viaduct is constructed. 15 river bridges are completed and 4 are in the advanced stages of construction. Out of
12 stations, 5 are completed and 3 more are now reaching completion stage. The station at BKC is an
engineering marvel. The station will be located 32.5 m below ground and the foundation is designed to
support the construction of a 95 m high building above ground.Future Corridors in Pipeline: The success of the Mumbai-Ahmedabad High-Speed Rail (MAHSR)
project is laying the foundation for future bullet train corridors in India. Future corridors are also
under active consideration.
This remarkable pace of development showcases India’s capability to execute world-class infrastructure using
cutting-edge global technology, with Japan playing a pivotal role as a trusted partner in this transformative
journey.
