NYC subway power surge investigation: Hochul on what went wrong, what's being done to fix it

A momentary power surge disrupted half of the New York City subway system for several hours and stranded hundreds of passengers, Gov. Kathy Hochul said Monday. During an investigation, the MTA found "a sequence of failures" in some of their backup systems, Hochul said. She directed the transit agency to have two independent engineering firms help them with a deep dive into what happened so they can make sure it doesn't happen again.
