A second tunnel boring machine has started excavation for the rail tunnel beneath Thane Creek in Maharashtra, marking another step forward for the Mumbai-Ahmedabad bullet train project. Officials said the machine began work on Saturday on one of the corridor’s most important engineering stretches.
The Thane Creek section is especially significant because it is set to become India’s first undersea tunnel for any rail corridor. That makes this part of the high-speed rail line a major milestone, both for the project itself and for large-scale transport construction in the country.
According to the available details, the newly deployed machine is among the largest tunnel boring machines used for rail tunnel construction in India. Its launch adds momentum to excavation work on a section that is expected to play a central role in linking key parts of the route.
The start of a second TBM also suggests a faster push on this technically demanding portion of the bullet train corridor. As tunneling progresses beneath Thane Creek, the project continues to highlight the scale of engineering involved in building India’s planned high-speed rail network.
