L&T bags major electrification and systems contract for Mumbai Metro Line 4 project

Mumbai, India (Metro Rail Today): Larsen & Toubro (L&T)’s Transportation Infrastructure business vertical has secured a significant contract for the Mumbai Metro Line-4 project, further strengthening its position in India’s fast-expanding urban transit market.

The latest contract – Package CA-298, awarded by the Mumbai Metropolitan Region Development Authority (MMRDA) – covers the electrification of the 24.72 km-long Line 4 corridor connecting Bhakti Park (Wadala) to Cadbury Junction, comprising 22 elevated stations.

Under this package, L&T will undertake:

• design, manufacture and supply of traction and power supply systems

• installation, integration, testing and commissioning across 24.72 route km

• provision of SCADA system for Metro Line 4 & 4A, covering 32 stations, depots and receiving substations

• complete electrical and mechanical (E&M) works

• five years of comprehensive maintenance

L&T has stated that the entire work will be executed by its in-house design and project execution team, reinforcing its end-to-end capabilities in metro system delivery.

Third consecutive win on Line 4 & 4A corridor

This is the third successive order that L&T has won in the Mumbai Metro Line 4–4A corridor.

Earlier contract wins include:

• Package CA-234: rolling stock, CBTC signalling, telecom, platform screen doors, depot machinery & plant

• Package CA-168: 19.5 km ballastless track works across 15 stations

With Package CA-298, L&T now commands a substantial role across track, rolling stock, signalling and electrification for the corridor.

Mumbai Metro Line 4 is designed to:

• improve connectivity between Wadala, Ghatkopar, Mulund, Thane and Wadala–Kasarvadavali

• reduce traffic congestion along the eastern express corridor

• provide faster, cleaner and energy-efficient mobility

• support transit-oriented urban development in the metropolitan region

Mrs. Mamta Shah, MD & CEO, Urban Infra Group, said:

“L&T’s latest systems contract for Mumbai Metro Line 4 underlines the growing maturity of India’s metro engineering ecosystem. With integrated responsibilities spanning rolling stock, signalling, track and electrification, such large turnkey packages help accelerate project timelines while ensuring higher reliability and passenger safety. Mumbai’s suburban commuters stand to benefit significantly as Line 4 and 4A move closer to completion.”

With multiple metro projects progressing simultaneously in Mumbai, including Lines 2A, 2B, 3, 4, 4A, 5, 6 and 7, the city continues to witness one of the largest urban transit expansions in India. L&T’s repeated successes in the corridor reflect the infrastructure major’s strong execution capability and competitive edge in the EPC metro systems space.
