Mumbai Bullet Train Station Hits Milestone with 1st Concrete Base Slab Cast
The first concrete base slab of the Mumbai Bullet Train Station was cast on November 30, 2024, at a depth of 32 meters—equivalent to a 10-story building. This milestone marks the beginning of foundational work for the station, located at Bandra Kurla Complex, Maharashtra, the only underground station on the Mumbai-Ahmedabad High-Speed Rail (HSR) corridor.
The station is being constructed using the bottom-up method, starting with excavation and progressing from the foundation. The slab, measuring 30 meters in length, 20 meters in width, and 3.5 meters deep, is the first of 69 slabs planned for the project.
Key details of the slab include the use of 681 MT of high-grade steel reinforcement, 6,200 rebar couplers, and 2,254 cubic meters of M60-grade concrete. Concrete pouring was conducted under temperature-controlled conditions, maintained below 25°C using ice and chiller plants. Two in-situ batching plants with a 120 m³ capacity each were deployed to ensure a steady supply.
The station, designed for efficient passenger movement, will feature three floors: a platform at 24 meters depth, a concourse, and a service floor. It will include six platforms, each 415 meters long to accommodate 16-coach bullet trains, with connectivity to Metro Line 2B and local roads via two entry/exit points.
Ample waterproofing measures and passenger amenities are integral to the design, ensuring a seamless experience for future users.
