Larsen & Toubro (L&T) has been awarded the contract for Package CA-234 under Mumbai Metro Line 4 & Line 4A, covering a 35.2 km stretch connecting Wadala, Kasarvadavali, and Gaimukh. The Mumbai Metropolitan Region Development Authority (MMRDA) declared L&T as the lowest bidder for this significant portion of the metro expansion project, with an estimated value of Rs 42.79 billion and a 19-year contract duration. 

The MMRDA had re-invited bids for this contract in February 2024. In November 2024, the technical bids revealed that two firms had submitted proposals for the contract. 

Under this contract, L&T will supply and install critical systems, including: 

Funding for the project will be provided by Germany’s KfW, which will loan € 545 million for the design and construction phases, expected to take 168 weeks (approximately 3.2 years). MMRDA will oversee the maintenance for 17 years, including 2 years for defect management.

 

The scope of work includes the design, manufacture, supply, installation, integration, testing, and commissioning of the rolling stock, signalling systems, telecommunications, platform screen doors, and depot machinery. This also includes 15 years of comprehensive maintenance after the initial 2-year defect liability period.

 

The delivery schedule for the 39 trains is as follows: 

This development comes three years after Alstom Transport, initially awarded contracts for trains and signalling for Line 4, withdrew from the project in 2022 due to delays in civil construction, particularly the train depot, which lacked a finalised location at the time.
