The Mumbai HSR station is the only underground station on the Mumbai-Ahmedabad High-Speed Rail corridor. It will have 6 platforms, each approximately 415 meters long, which is sufficient to accommodate a 16-coach bullet train. The platform is planned at a depth of about 24 meters from the ground level, and the station will have three floors including platform, concourse, and service floor.

Two entry and exit points are planned—one to facilitate access to the nearby metro station of metro line 2B and the other towards the MTNL building. The station is designed to provide ample space for passenger movement and amenities at both concourse and platform levels. Dedicated skylight provisions have been made to allow natural lighting inside the station.

The station will offer modern passenger amenities including security, ticketing, waiting areas, business class lounge, nursery, rest rooms, smoking rooms, information kiosks, incidental retail, public information and announcement systems, and CCTV surveillance. Additionally, integration with other modes of transportation such as metro, buses, autos, and taxis has been planned to ensure seamless connectivity.

Construction Update (12/09/2023): The land required for constructing the BKC station, approximately 4.8 hectares, has been handed over to the contractor by :contentReference[oaicite:0]{index=0}. The station will be constructed using the bottom-up method, where excavation begins from ground level and concrete work starts from the foundation. The excavation will reach a depth of about 32 meters, involving approximately 18 lakh cubic meters of earthwork.

To ensure safety during deep excavation, a ground support system is being implemented using 3382 secant piles, each with depths ranging from 17 to 21 meters. These piles are reinforced with ground anchors and walers at intervals of 2.5 to 3.5 meters as excavation progresses. Currently, around 559 labourers and supervisors are working at the site round the clock, and this number is expected to increase to nearly 6000 during peak construction phases.

The primary ongoing activity at the site is the installation of secant piles, with 14 piling rigs deployed for this purpose.
