The first tenders for the Maharashtra leg of Mumbai-Ahmedabad Bullet train project were floated on Tuesday by National High Speed Rail Corporation Ltd (NHSRCL) for tunnel work between Mumbai-Thane. The tenders were floated for work, including testing and commissioning of a double line high-speed railway using tunnel-boring machines (TBMs) and a new Austrian tunnelling method (NATM).
