The electrical infrastructure of the New York City subway experienced a major power outage in 2024 due to a malfunction at a Brooklyn substation dating from the 1930s. The outage affected thousands of passengers on the A, C, F, and G lines, leaving trains unable to move for an extended period.
The Metropolitan Transportation Authority (MTA) operates 225 substations across the city, many of which are nearly 100 years old. The inefficiency and difficult maintenance of old equipment negatively impact the system's reliability. MTA officials say such failures cause serious disruptions to subway services.
To address these issues, the MTA plans to invest $4 billion by 2029 to renew 75 substations. It also aims to deploy the new Communications-Based Train Control (CBTC) wireless signaling system to make trains run more reliably and at frequent intervals. These investments are expected to increase the reliability of subway services and reduce passenger disruptions.
