Station details

Bandra Kurla Complex station to be engineering marvel

The station at Bandra Kurla Complex (BKC) is touted as an engineering marvel. It will be located 32.5 meters below ground with a foundation strong enough to support a 95m-high building above ground. "The success of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) project is laying the foundation for future bullet train corridors in India. Future corridors are also under active consideration," it added.
