Larsen & Toubro (L&T), in partnership with Alstom Transport, has secured a contract to supply essential systems for Mumbai Metro's 35.2 km Line-4 and Line-4A (Green Line), which will connect Wadala, Kasarvadavali, and Gaimukh. Identified as Package CA-234, the contract includes the supply of 39 six-coach trains, totalling 234 coaches, along with Communication-Based Train Control (CBTC) signalling and train control systems, telecommunications infrastructure, platform screen doors, and depot machinery for the Mogharpada Depot.

This project comes after Alstom's previous withdrawal from a similar contract in 2022 due to delays in civil construction and depot finalization. Following the reissuance of bids by the Mumbai Metropolitan Region Development Authority (MMRDA) in February 2024, L&T emerged as the lowest bidder. The project is being financed by a €545 million loan from Germany’s KfW for the design and build component, which is expected to take approximately 3.22 years. MMRDA will finance the comprehensive maintenance phase, which will span 17 years.

The contract outlines a stringent delivery timeline, with the first prototype train scheduled for delivery within 52 weeks of contract signing. Subsequent deliveries are planned to ensure full deployment of the trains. MMRDA has set a target for Phase 1 certification for revenue operations by August 2026, although the impact of previous delays could affect this timeline.
