Larsen & Toubro (L&T) has won a major contract from the Mumbai Metropolitan Region Development Authority (MMRDA) for work on Mumbai Metro Line 4 and Line 4A. The project covers a total length of 35.2 km and will connect Wadala, Kasarvadavali, and Gaimukh, improving east-west and north-south travel in

the Mumbai Metropolitan Region.

The contract, known as Package CA-298, mainly focuses on power supply and traction systems. Under this package, L&T will design, manufacture, supply, install, test, and commission the power and traction systems for 24.72 km of the metro route. In addition, the company will provide the SCADA (Supervisory Control and Data Acquisition) system for the entire Line 4 and Line 4A network. This system will cover 32 metro stations, depots, and receiving substations, helping in the smooth monitoring and control of operations.
Electrical & Mechanical Work
All work under this contract will be carried out by L&T's in-house design and execution teams. The scope also includes setting up electrical and mechanical systems, as well as installing lifts and escalators at 22 elevated stations. L&T will also handle work at two metro depots. After completion, the company will be responsible for the comprehensive maintenance of these systems for a period of five years.
L& T's 3rd Contract
This is the third consecutive contract that L&T has secured for the Mumbai Metro Line 4 and 4A corridor. Earlier, the company had received Letters of Award for Packages CA-234 and CA-168, thereby strengthening its role in this important metro project.
Package CA-234 covers the supply of metro trains, advanced Communications-Based Train Control (CBTC) signalling, telecom systems, platform screen doors, and depot machinery for the entire Line 4 corridor. Meanwhile, Package CA-168 involves the construction of 19.5 km of ballastless tracks across 15 stations on Lines 4 and 4A.
