MMRDA invites bids for ₹4,882 Crore Rolling Stock & Systems Contract for Mumbai Metro Line 12

Mumbai, India (Metro Rail Today): The Mumbai Metropolitan Region Development Authority (MMRDA) has invited bids for a major integrated systems contract worth ₹4,882 crore for the upcoming Mumbai Metro Line 12, marking a significant step forward in the development of the city’s expanding metro network.

The tender covers a comprehensive package involving rolling stock, signalling, telecommunications, power supply, depot equipment, lifts, escalators, and associated metro systems required for the operation of the corridor. Industry observers view the package as one of the largest systems contracts awarded under Mumbai Metro’s ongoing expansion programme.

According to the tender issued by MMRDA, the selected contractor will be responsible for the design, manufacture, supply, installation, integration, testing, and commissioning of the complete metro systems package. In addition to project execution, the contractor will also undertake five years of comprehensive maintenance following the completion of a two-year defect liability maintenance period, ensuring long-term reliability and performance of the corridor’s critical infrastructure.

The tender has been issued under Tender No. MMRDA/ML-12/MMRP/CA-315 with an earnest money deposit (EMD) requirement of ₹24.40 crore. A pre-bid meeting has been scheduled for 5 June 2026, while bid submissions will close on 25 June 2026.

The scope of work includes the supply of metro trainsets, implementation of Communication-Based Train Control (CBTC) signalling technology, telecommunication systems, traction and power supply infrastructure, depot machinery and plant, electrical and mechanical systems, as well as passenger convenience facilities such as lifts and escalators. The integration of these systems will be critical to ensuring safe, efficient, and reliable operations once the line becomes operational.

Mumbai Metro Line 12 forms an important part of MMRDA’s broader strategy to strengthen public transportation across the Mumbai Metropolitan Region. The corridor is expected to enhance connectivity between rapidly developing residential, commercial, and industrial areas, while providing commuters with a faster and more sustainable alternative to road-based transport.

The project is also expected to support Mumbai’s long-term mobility goals by reducing traffic congestion, lowering travel times, and encouraging a shift toward mass transit solutions. As the metropolitan region continues to witness rapid urbanisation, investments in advanced metro infrastructure are increasingly being viewed as essential for maintaining economic productivity and improving quality of life.

The inclusion of state-of-the-art CBTC signalling technology will enable higher operational efficiency, improved safety, and the ability to run trains at shorter intervals, thereby increasing passenger carrying capacity. Similarly, the deployment of modern rolling stock and energy-efficient power systems is expected to contribute to a more reliable and sustainable urban transit network.

Commenting on the development, Mrs. Mamta Shah, MD & CEO, Urban Infra Group, said: “The launch of this integrated systems tender demonstrates the scale and ambition of Mumbai’s metro expansion programme. Advanced signalling, modern rolling stock, and robust power infrastructure will be crucial in delivering safe, efficient, and passenger-centric urban mobility solutions for the growing Mumbai Metropolitan Region. Such investments are instrumental in building sustainable cities and strengthening India's urban transportation ecosystem.”

With the issuance of this high-value systems package, MMRDA has taken another major step toward the realization of Mumbai Metro Line 12, reinforcing its commitment to developing a world-class metro network capable of meeting the future mobility needs of one of the world’s fastest-growing urban regions.
