Railway Minister Ashwini Vaishnaw will inaugurate the underground tunnel-boring work from Vikhroli to the Bandra Kurla Complex station in Mumbai on Sunday, marking the maiden use of a tunnel boring machine for the country's first bullet train project, between Mumbai and Ahmedabad.
Imported via the sea route from China in March 2026, the two customised German-made tunnel boring machines (TBMs) are owned by Afcons Infrastructure Limited, which is constructing a 20.37-km tunnel, including a 7-km undersea stretch. The tunnel will be built at a depth of about 65 metres below ground level.
