The train that "passed over" Horne contained two engines and one car.
"She was just very fortunate," Capt. Lorenza Dorsey told Al.com. "I have never seen anything like it."
Dorsey said Horne's slight frame may have kept her from getting injured.
"The train went by her very quickly," Dorsey said. "It wasn't like it was a long freight train."
Horne was charged with disorderly conduct for causing a disruption because the train had to be stopped and an ambulance needed to be called. She was also charged with public intoxication.
The lucky lady was taken to a hospital for examination just in case.
