The MTA says 3,500 commuters were left stranded underground for hours after a sudden power outage affected the A, C, F and G subway lines in Brooklyn on Tuesday evening.

A TikTok video captured the scene as MTA workers assisted passengers, guiding them safely off the trains and onto the tracks to exit the station.

The FDNY says four people sustained minor injuries, with one person sent to a hospital for evaluation.

Commuters shared their frustrations as the problem affected their commute home.

"I waited for about 15-20 minutes, but no train came. Now, I’m just trying to figure out which other train I can catch," said LaVar Sprinkle from East New York.

Con Edison says the power disruption was caused by a feeder cable failure that powers the third rail on the A, C, F, and G lines.
