Supporting seamless operations across underground and elevated corridors, ABB’s advanced electrification and motion-control solutions have been deployed across key metro infrastructure facilities. Today, the 72-km metro system operates more than 300 train trips daily and serves over half a million passengers, playing a vital role in easing traffic congestion and promoting sustainable mobility in the city. A wide range of ABB Electrification solutions, including low-voltage and medium voltage gas-insulated switchgear, lightning protection systems, distribution boards, and variable frequency drives (VFDs), have been deployed across various station and tunnels throughout the network. These solutions are designed to optimize space, reduce downtime, support efficient operations, and enable safe ventilation, contributing to operational continuity. ABB Motion's HVAC-dedicated packaged drives help control critical cooling and ventilation infrastructure, supporting passenger comfort and safety during daily operations and smoke extraction functions during emergencies within the metro station, while making noticeable energy savings – on average of 25 percent. Kiran Dutt, President – Electrification, ABB India said “As India accelerates its journey toward low- carbon, smart urban transit, the need for highly efficient and intelligent solutions has never been more urgent.
