NHSRCL starts casting concrete segments for Mumbai-Ahmedabad bullet train project

A 21-km tunnel is under construction between the Bandra Kurla Complex and Shilphata for the bullet train project that will connect Mumbai to Ahmedabad. Of the total length, 16 km will be excavated using three Tunnel Boring Machines (TBMs), while the remaining 5 km will be built using the New Austrian Tunnelling Method (NATM) in the project undertaken by The National High Speed Rail Corporation.

High-strength M70 grade concrete is being used to ensure superior structural integrity and long-term durability. The casting and stacking yard, covering an area of 98,898 sqm (9.9 hectares) in Mahape, Thane district, Maharashtra, is currently being commissioned.

The yard is equipped with various cranes, gantries, and machines to automate and mechanize the casting operations, ensuring high-quality assurance during the casting and stacking of the segments. Additionally, the facility will include casting sheds, a stacking area, a batching plant, and a steam curing area.
