July 16, 2025: The Mumbai-Ahmedabad bullet train project has reached a major milestone with the opening of the first section of its 21-kilometre undersea tunnel, according to an announcement by the Ministry of Railways. This section forms a critical part of the high-speed rail line between Bandra-Kurla Complex (BKC) and Thane, and includes a 7-kilometre stretch beneath Thane Creek.
This undersea tunnel is part of the broader 508-kilometre corridor being constructed to bring high-speed rail connectivity between Mumbai and Ahmedabad. The project is advancing rapidly in Maharashtra, with construction efforts gaining significant momentum. To date, 310 kilometres of viaduct construction have been completed. Additionally, 15 river bridges have been built, with another four nearing completion.
Of the 12 planned stations along the route, five have been completed, and three are in advanced stages of construction. Work on laying tracks and installing overhead electrical systems is also progressing at a steady pace. The BKC station, one of the key nodes in the corridor, is designed to be situated 32.5 meters below ground. Its structural foundation has been developed to support a 95-meter-high building above it.
The entire corridor is being built using Japanese Shinkansen technology, known for its emphasis on high speed, safety, and reliability. As part of bilateral cooperation, the Japanese government has agreed to introduce E10 Shinkansen trains in both India and Japan simultaneously.
The ongoing procurement of systems for operations and control continues to advance. The successful implementation of complex engineering feats like undersea tunnels not only demonstrates technical capability but also reflects the country’s focus on building modern and future-ready infrastructure. The Mumbai-Ahmedabad bullet train project is expected to significantly improve inter-city travel and set a precedent for future high-speed rail developments in India.
