Larsen & Toubro (L&T) on Monday said it has secured a deal from the National High Speed Rail Corporation Limited (NHSRCL) to construct 156 route kilometres (RKM) of ballastless track for the Mumbai–Ahmedabad High Speed Rail (MAHSR) corridor.
While the construction major did not reveal the specifics of the contract, it classified it under a 'large project', which it states falls under a ₹2,500-₹5,000 crore deal.
The deal covers design, supply, construction, testing and commissioning on a design-build lump sum basis on the section between Mumbai’s Bandra-Kurla Complex and Zaroli village in Gujarat (package T1), the company said in an exchange filing. The order involves over 21 km of underground track and 135 km on elevated viaducts.
This is the second track-work order L&T has secured for the corridor. In April 2022, the company was awarded a contract covering 116 km from south of Vadodara to the Sabarmati depot (package T3). With the addition of the new contract, the firm said that it is now responsible for more than half of the total track works on the project.
It added that the Japanese Shinkansen J Slab Track technology will be used for the project, enabling train speeds of up to 320 km per hour and offering longer service life, improved ride quality and easier maintenance.

"Our success in T3 package involved rapid technology absorption, indigenisation of plant & machinery and value engineering. This has been a key factor in our approach to this new order, and we are confident of delivering on time," said SV Desai, whole-time director and senior executive vice president (civil infrastructure) at L&T.
L&T has previously worked on ballastless track projects for metro networks in Bengaluru, Chennai and Mumbai, and internationally in Jakarta, it added.
The Mumbai–Ahmedabad bullet train project spans a 508 km corridor and is designed for trains running at speeds of up to 320 km per hour, connecting Mumbai and Ahmedabad through 12 stations. According to NHSRCL, 320 km of viaduct has been completed so far, along with 17 river bridges, nine steel bridges and five concrete bridges. In addition, 202 km of track bed has been constructed.
