Note remote control "caboose".

This skyshot shows the layout of the tank cars just after most of the fires are out. The "remote control caboose" is among the five cars at the upper left. There are three tracks running out of the pile-up, and one coming in at the bottom, indicating the switch point contributing to the derailment.

What I haven't seen yet is an over view or skyshot showing where the engines and any attached cars ended up, and why. The story is that they stopped a couple of clicks prior to the entry to the town.
