Chris Karnes, a passenger on the train, described the scene to CBS news affiliate KIRO-TV. "We had just passed the city of DuPont and it seemed like we were going around a curve. All of a sudden, we felt this rocking and creaking noise, and it felt like we were heading down a hill. The next thing we know, we're being slammed into the front of our seats, windows are breaking, we stop, and there's water gushing out of the train.

We all tried to stop quickly to avoid running into each other, to be honest.
