WATCH: Power Cut Leaves Commuters at NYC’s Grand Central Terminal in the Dark

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.

Power was gradually restored, first to the upper concourse at 8:53 p.m., then to the lower level by 9:17 p.m.. Officials added that no one was injured, although five Metro-North Railroad staffers were temporarily trapped in elevators until emergency generators kicked.

The MTA said it is working with Con Edison to identify the cause of the outage.
