Mumbai–Ahmedabad High-Speed Rail Tunnel

under construction

Construction of the underground section of the Mumbai–Ahmedabad high-speed rail corridor has entered a crucial engineering phase with the installation of a second tunnel boring machine assembly near Mumbai. The project involves creating a deep tunnel network through densely populated urban terrain and challenging geological conditions, using specialised slurry-based tunnel boring systems to maintain excavation stability and minimise surface disruption. The tunnel will accommodate both directions of the high-speed rail alignment, improving connectivity between Mumbai, Surat, Vadodara, and Ahmedabad.
