So I am not 100% sure yet. Agree on the "ride up" motion... thanks for the info Thanks Scott – over on subchat most are saying that there was no single-tracking in the area where the accident took place.

If you look at photos and a map you will see that the two trains collided at an area where there is a sharp bend in the tracks. According to Wikipedia, both trains de-railed and then collided. I have not heard any substantiated evidence for this de-railment theory though. Two trains being piled on top of each other is severe, but the trains are designed to ride up on each other in the event of a collision so that the "accordion" type force that causes a lot of injuries is mitigated...
