Human errors caused a subway train car to jump its track, slightly injuring 19 passengers, authorities said Sunday.
At least 16 of the injured were taken to area hospitals and treated for minor injuries, said Laura Gillig, a spokeswoman for Metropolitan Atlanta Rapid Transit Authority. All were released, she said.
The accident occurred Saturday evening.
MARTA officials said the first mistake was made by the driver, who decided to move the train past a red signal. The command center then allowed her to back the train up, which bent a track switch and caused a car in the middle of the six-car train to jackknife. The car remained upright.
