January 29, 2026: Mumbai’s urban rail network is set to take a technological step forward with the award of a major contract for next-generation traction systems on Metro Lines 5 and 6. The move signals a focus on improving reliability, energy efficiency and long-term sustainability as the city scales up mass rapid transit across the metropolitan region. Global electrification and automation major ABB India has secured the order to supply integrated propulsion and control solutions, reinforcing the push towards low-emission and resilient urban mobility.
The contract has been placed by rolling stock manufacturer Titagarh Rail Systems Ltd and covers equipment for 40 six-car trainsets planned for the Orange Line (Line 5) and the Pink Line (Line 6). Line 5 will connect Thane and Kalyan via Bhiwandi, while Line 6 will run from Swami Samarth Nagar to Vikhroli, linking densely populated residential and employment zones. The scope includes traction converters, auxiliary converters, traction motors and Train Control and Management System (TCMS) software.
Urban transport specialists highlight that traction systems form the backbone of metro performance, governing how electrical power is converted into motion and how onboard systems are managed. Efficient integration of propulsion hardware with control software can deliver smoother acceleration, reduced energy losses and more responsive train operations, translating into improved commuter experience and lower operating emissions.
A notable feature of the project is its emphasis on localisation. Traction converters will be manufactured in Bengaluru, while traction motors will be produced in Vadodara, supported by domestic engineering, testing and service teams. This approach aligns with national manufacturing initiatives such as Make in India and Atmanirbhar Bharat, aimed at strengthening indigenous capabilities in critical infrastructure technologies and reducing reliance on imports.
Industry observers say the contract could help build a more robust local supply chain for metro rolling stock components, an area that has lagged behind network expansion in many Indian cities. For Mumbai, Lines 5 and 6 are strategically important corridors where enhanced metro connectivity is expected to ease road congestion, link suburban hubs and encourage a shift away from private vehicles.
As implementation progresses, coordination with track, signalling and depot readiness will be crucial. If executed smoothly, the project could offer a blueprint for future metro expansions nationwide, combining advanced engineering, domestic manufacturing and climate-aligned transport goals.
