Summary
Alstom to provide 39 driverless trainsets & CBTC signalling system for Mumbai Metro Line 4, enhancing commuter experience & connectivity.
Alstom, a global leader in sustainable mobility, has secured a significant contract to supply 39 driverless trainsets and a Communications-Based Train Control (CBTC) signalling system to Mumbai Metro Line 4. The contract, valued at a few hundred million euros, includes maintenance services for five years. The Mumbai Metro Regional Development Authority awarded the contract to Larsen & Toubro India, which has partnered with Alstom for this project.
The 39 trainsets, each comprising 6 cars, will be manufactured in India, adhering to the 'Make in India' initiative. Alstom's expertise in CBTC technology will enable driverless operation across the 35.3 km stretch of Mumbai Metro Line 4, connecting Wadala and Kasarvadavali with 32 stations. This project aims to enhance connectivity in Mumbai, alleviate traffic congestion, reduce CO2 emissions, and improve public infrastructure.
The introduction of these driverless trains will offer passengers a unique design, enhanced comfort, and advanced safety features like electrical braking and cybersecurity measures. Alstom's maintenance services will ensure the reliable and safe operation of the fleet. The company's Urbalis technology will provide the highest Grade of Automation (GoA4), commonly known as 'driverless technology,' for efficient train operations.
The initiative underscores Alstom's commitment to sustainable and smart mobility solutions worldwide. With a proven track record in the mass transit market and extensive experience in CBTC technology, Alstom is set to elevate Mumbai's metro network with cutting-edge solutions. The company's past contributions to Mumbai's metro network, like the Aqua Line, signify its dedication to transforming urban transportation.
As Mumbai Metro Line 4 progresses towards completion, trial train coaches have already been deployed for testing on the tracks, signaling tangible progress in the project. The upcoming metro corridor, designated as the Yellow Line, is poised to significantly improve connectivity between Mumbai and Thane, offering a crucial link for commuters in the region.
The collaborative efforts of Alstom and Larsen & Toubro highlight a shared commitment to delivering world-class mobility solutions and enhancing urban infrastructure. The innovative technology, along with the focus on passenger comfort and operational efficiency, promises to elevate the commuter experience on Mumbai Metro Line 4.
