I know I haven't. I know someone who's been in two. He was involved in a small one in Vermont where the Vermonter derailed an engine and a car, nothing over turned, no serious injuries, the only fatality was the truck driver. He was in the Auto Train wreck, we all know how that went. He was downstairs in the smoking lounge for the coaches at the time. He'd just showered after making up the train in Sanford yard, well the shower's effect didn't last long. He was nearly buried alive in ballast as the car toppled, but he walked away with a few bruises, and "I didn't realize it til I left, but I had rocks in my pockets."
