The Mumbai-Ahmedabad slug bid task has achieved different milestone with the excavation of a upland passageway successful Maharashtra's Palghar, which is the 3rd successful the territory successful the past 5 months, officials said connected Tuesday (June 2, 2026).
The National High Speed Rail Corporation Limited (NHSRCL), which is implementing the project, said this important breakthrough was achieved connected June 1.
Engineers successfully completed the excavation of the 3rd upland passageway (MT-07) astatine Ambesari colony successful Dahanu taluka of Palghar district, marking a important measurement guardant for the Mumbai-Ahmedabad slug bid project, the NHSRCL said successful a connection connected Tuesday.
With this latest achievement, the task has successfully excavated 3 upland tunnels wrong the past 5 months alone, signaling accelerated operation advancement successful 1 of the corridor's astir geographically analyzable stretches, it said.
The newly-excavated passageway spans 417 metres successful magnitude and features a monolithic width of 14.4 metres. The operation has been specifically designed to accommodate some the up and down tracks of the high-speed slug bid corridor, according to the statement.
To carve done the rugged terrain, the NHSRCL utilized a highly coordinated controlled drilling and blasting method, executing the excavation simultaneously from some ends.
Given the logistical challenges of upland excavation, precocious monitoring systems and geotechnical instruments were deployed to guarantee full structural stability, it said.
The tract featured real-time monitoring technologies, including Surface Settlement Points (SSP) and 3D targets to way crushed movement; strain gauges and seismographs to continuously show vibrations and passageway behavior, protecting adjacent structures.
Strict information protocols were successful spot for workers, including state-of-the-art ventilation systems, occurrence information measures, and controlled entree arrangements, the NHSRCL said.
The palmy excavation of MT-07 officially completes each 3 upland tunnels (MT-08, MT-07, and MT-06) located betwixt the Vapi (Gujarat) and Boisar (Maharashtra) slug bid stations.
This circumstantial conception of the corridor cuts done a captious concern belt.
The accelerated completion of these tunnels ensures that the high-speed nexus betwixt these 2 large economical hubs remains connected track.
The ambitious task requires a full of 8 upland tunnels, with 7 located successful Palghar and 1 successful the Valsad (Gujarat).
The 508-km railway task connecting Mumbai and Ahmedabad, which passes done Gujarat, Maharashtra, and Dadra and Nagar Haveli, is India's lone high-speed obstruction task designed to run slug trains astatine a velocity of 320 kmph.
The task is being executed with method and fiscal assistance from the Japanese government.
The corridor volition link large cities, including Sabarmati, Ahmedabad, Anand, Vadodara, Bharuch, Surat, Bilimora, Vapi, Boisar, Virar, Thane, and Mumbai. Once completed, the task volition trim question clip betwixt Mumbai and Ahmedabad to conscionable 1 hr and 58 minutes, officials person said.
The task achieved its 2nd passageway breakthrough successful February this twelvemonth adjacent Saphale colony successful Palghar district. A period anterior to that (in January), different breakthrough of the MT-5 passageway was achieved adjacent Saphale.
