Mumbai-Ahmedabad High-Speed Rail: On Monday, the casting of a full span pre-stressed concrete (PSC) box girder to be used for upcoming India’s first, Ahmedabad-Mumbai Bullet Train corridor was launched. Minister of State for Railways Darshana Jardosh who was present during the inauguration was quoted saying in a PTI report that the first trial run of the high speed train between Surat and Bilimora stations in Gujarat was likely to take place by July 2026. On Monday, the casting of the girder was initiated at a casting yard near Naslipore village, and it was the second PSC box girder being developed for the Bullet Train corridor, said the project’s implementing agency- National High Speed Rail Corporation Limited (NHSRCL).

Four days ago, the first such full span girder was built in a casting yard in the district of Anand, the agency said, adding that the box girder of 40 meter span will weigh approximately 970 tonnes. According to NHSRCL, the PSC box girder, which will be the heaviest in India’s construction industry, is being cast as a single piece, that is without any construction joint, with 42 tonnes of steel and 390 cubic metres of concrete. Jardosh also said this is the first time that such a large girder will be cast in India. As the launching process of the former was seven times faster, full span girders were preferred over segmental girders, NHSRCL said. It further added that 23 casting yards, on plots ranging from 16 acres to 93 acres, have been set up along the high speed rail corridor’s alignment.
