PremiumFor Mumbai’s first fully underground metro project which is the Colaba-Bandra-SEEPZ Metro's line 3, the city's first fully underground corridor, French rolling stock manufacturers Alstom has indigenously designed and manufactured, and commissioned 31 lightweight, fully furnished modern passenger train sets of 8 cars each. These metro trains are estimated to reduce 35% of overall traffic and help in reducing air and noise pollution.
The Alstom’s Metropolis trainsets set the standard in energy-efficient, and safe operations. Themed on ‘Dynamic Fluidism’ that takes inspiration from the city, these trains prioritize high interior density layout to maximize space efficiency, enabling each trainset to carry 3,000 passengers per trip. It offers a unique design, and a wide range of configurations and ensures the highest performance due to the perfect combination of proven and reliable components and innovations. These metro trains are a testament to the company’s superior eco-design principle, with 96% of the mass of materials and components used being recyclable, and 99% recoverable.
In a nutshell, the ecodesign performance achieved for Mumbai Line 3 are as follows:
Energy consumption: 8.40 kWh/passenger/km. This is the energy required in kWh to transport one passenger for 1 kM. Alstom is targeting to achieve 25% reduction in energy consumption for overall product lines by 2025.
Noise level: While 82 dBA @ 75 km/h is the approved limit, Alstom has successfully reduced the noise levels below this level.
Recyclability and recoverability potential: As per calculations based on ISO 22628 standard, these trains are 96% recyclable and 99% recoverable.
Use of Clean materials: No prohibited substances have been used in this project, as per the applicable regulations.
Alstom is also equipping this line with the latest generation of CBTC signaling technology (Urbalis 400). This is Alstom’s proprietary technology that results in increasing average capacity by 30% in manned services and unattended train operations (UTO) and helps reduce energy consumption by 30%.
Meanwhile, the DMRC will be responsible for the day-to-day operations of the metro line, including management of operation control centre, depot control centre, stations, running trains, maintenance of trains and all metro systems infrastructure, and ensuring the safety of passengers, MMRC in a release said. “They will be governed by key performance indicators (KPIs) to ensure clean, efficient and hustle-free services to Mumbaikars," it stated. Awarding the operation and maintenance contract was a “significant milestone for the MMRC in making the line operations", the release said. The DMRC is a pioneer in the metro rail sector in India, having successfully operated and maintained the Delhi metro for over two decades, it said.
