“`html

Introduction

National High Speed Rail Corporation Ltd (NHSRCL) has awarded Larsen & Toubro (L&T) a contract to construct a 156 km section of the Mumbai-Ahmedabad High Speed Rail (HSL) project, with track-works spanning from Mumbai (Bandra-Kurla complex) to Zaroli village in Gujarat.

Contract Details

The contract, designated as Package T1, encompasses the design, supply, construction, testing, and commissioning of track-works on a design-build lump sum price basis. This includes over 21 km of track-works in underground sections, corresponding to Civil packages of C1 and C2, and 135 km of track on elevated viaduct sections (Package C3).

Larsen & Toubro’s Involvement

This marks the second track-work package L&T has secured for the Mumbai-Ahmedabad HSL project. In April 2022, NHSRCL awarded L&T the contract for the design and construction of 116 km of the high-speed line (Package T3), extending from south of Vadodara city to Sabarmati depot. According to L&T, the project is progressing rapidly, and with this latest order, the company now holds responsibility for over 50% of the track-works within the Mumbai-Ahmedabad high-speed railway.

Technology and Implementation

The track-works will utilize Japanese Shinkansen J slab track technology, designed to facilitate speeds of up to 320 km/h. This technology aims to improve ride quality, increase service life, and enhance maintainability. S.V. Desai, Director of the Civil Infrastructure division of L&T, stated that the company’s success in the T3 package, which involved rapid technology absorption, indigenization of plant and machinery, and value engineering, has been a key factor in their approach to this new order.

Project Overview

The Mumbai-Ahmedabad HSL project represents India’s first bullet train corridor and is approximately 508 km long. It will connect Mumbai in Maharashtra with Ahmedabad in Gujarat, reducing travel time between the two cities to approximately two hours. The project is supported by technical and financial contributions from Japan, and incorporates Shinkansen technology. The National High-Speed Rail Corporation Limited (NHSRCL) manages the project, which will feature elevated tracks, dedicated stations, and advanced safety systems.
