Mumbai-Ahmedabad Bullet Train: 300 Km Of Viaduct Work Completed, Says Union Minister Vaishnaw.

Union Railways Minister Ashwini Vaishnaw today announced a significant milestone in India's ambitious Bullet Train Project, confirming the completion of 300 kilometers of viaduct.

The high-speed rail corridor project is being executed by the National High-Speed Rail Corporation Limited (NHSRCL).

Further progress has been made on the Mumbai bullet train station at Bandra Kurla Complex (BKC), which is the sole underground station on the Mumbai-Ahmedabad High-Speed Rail Corridor. Approximately 76 percent of the excavation work for this station has been completed, with 14.2 lakh cubic meters already excavated out of a total requirement of 18.7 lakh cubic meters.

To support the extensive concrete work, three batching plants with a capacity of 120 cubic meters per hour are operational at the site. These plants are equipped with ice and chiller facilities to maintain controlled concrete temperatures, crucial for the project's demanding specifications. A modern concrete lab is also present on-site, conducting various tests including Water Permeability and Rapid Chloride Penetration tests, with intermittent sample verification at a reputed external laboratory.

The station's base slab is being cast with M-60 grade temperature-controlled concrete. Each base slab casting requires a substantial 3,000 to 4,000 cubic meters of concrete, produced by the in-situ batching and chiller plants.

The platform for the BKC station is planned at a depth of approximately 26 meters below ground level. The station will feature three floors: the platform, concourse, and service floor. Excavation work is progressing to a depth of up to 32 meters (approximately 100 feet) from ground level, equivalent to a 10-storey building.
