India has achieved a major milestone in its high-speed rail journey with the opening of the first section of a 21-kilometre undersea tunnel between Ghansoli and Shilphata in Maharashtra, part of the Mumbai–Ahmedabad Bullet Train project. The project has already completed 310 kilometres of viaduct construction, with parallel progress in track laying, overhead electrification, station development and bridge construction. System procurement for operations and control is also advancing steadily.
The entire 508-kilometre corridor will be powered by Japanese Shinkansen technology, setting new standards in speed, safety and reliability. Japan has confirmed the simultaneous launch of its next-generation E10 Shinkansen trains in both India and Japan, replacing the current E5 fleet. This decision reflects the depth of India–Japan strategic and technological cooperation.
Civil construction is progressing rapidly across the alignment. Fifteen river bridges have been completed and four more are in advanced stages. Out of twelve stations planned for the route, five have been completed and three more are nearing completion. The terminal station at Bandra Kurla Complex is considered an engineering marvel, built 32.5 metres below ground with a foundation capable of supporting a 95-metre tall structure above.
India’s swift execution of this transformative infrastructure demonstrates the country’s readiness to deliver world-class transport systems using global technology. The success of the Mumbai–Ahmedabad Bullet Train is laying the groundwork for future high-speed rail corridors across the country, with additional routes under active consideration. Japan remains a trusted partner in this journey, contributing cutting-edge rail systems and institutional expertise.
