The construction of the Mumbai-Ahmedabad bullet train project is progressing steadily, with significant progress recorded across viaducts, track infrastructure, electrification, bridges and tunnels, according to the latest progress update released by National High Speed Rail Corporation Limited (NHSRCL).
The 508-km Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor, which is India’s first bullet train project, is being implemented by NHSRCL.
According to NHSRCL’s July progress update, pier work has now been completed over 453 km of the corridor, while viaduct construction has reached 359 km.
Work on systems that will eventually support train operations is also advancing, with Reinforced concrete (RC) track bed construction completed over 215 km, while track slabs have been laid with Cement Asphalt Mortar (CAM) injection completed over 91 km.
Further, electrification infrastructure is also expanding, with over 9,000 Overhead Equipment (OHE) masts installed across 200 km of the corridor, according to the update.
These masts will form part of the overhead traction system required to supply power to high-speed trains.
Additionally, substantial progress has been recorded on measures aimed at controlling operational noise.
Noise barriers have been installed along 297 km of the alignment.
The barriers are being placed along the viaduct to reduce the transmission of noise generated during high-speed train operations.
Bridge construction has also progressed on the corridor with a total of 17 river bridges completed, along with 15 steel bridges.
The steel structures are being used at locations where the high-speed rail alignment has to cross existing railways, highways and other infrastructure where conventional viaduct construction may not be suitable.
Tunnel construction in Maharashtra has also moved ahead, with the July update showing that four mountain tunnels have been completed, while 5 km of tunnel constructed using the NATM method has also been completed.
The Mumbai-Ahmedabad corridor will run for about 508 km from the Bandra Kurla Complex area in Mumbai to Ahmedabad, creating a high-speed rail link between major economic and industrial centres in Maharashtra and Gujarat.
