As you know, I love my trains. I also love storms. Here is a video showing what happens when you mix the two together. From my understanding of this video, this tornado occurred in Illinois back in 2008. There was no way for the train to avoid the powerful storm as it crossed its path. The end result is predictable.
While watching the video, look at the upper right- and left-hand corners. You can see how conditions change real quick by the way the trees suddenly wave out of control. Very impressive!
