"We were going down the tracks between 70 and 80 miles an hour, I would say, and we heard a creaking, a little bit of a creaking sound," Karnes, who was not seriously injured, told ABC News.

After that, the "train started to wobble for a moment," he recalled.

"And then we were catapulted at the seats in front of us, and the next thing that we knew, our car had crumpled at a portion at the top, and we were down an embankment," he added.

After the derailment, Karnes said his car, which had about 10 other passengers aboard, "came to rest on a hill."

"There was water, and a ton of dust flew up into the air," Karnes recalled.

"I don't know how to describe the noise. There was a crash. We knew that something had happened," he added.
