Viral footage shows the moment that commuters in New York City's famous Grand Central Terminal were plunged into darkness on Thursday night after a voltage drop cut power across parts of the iconic Manhattan hub. The Metropolitan Transportation Authority (MTA) confirmed the blackout struck at around 8:30 p.m., dimming lights across portions of the building while leaving train services untouched. No train service was impacted, officials said, noting that Grand Central Madison remained fully operational.
