This from JPVideos, a YouTuber I like. Jay's content mostly features historical rail and mining sites specifically in Pennsylvania that he travels to and documents by video. He offers much commentary, historical references, and of course speculation, to things there are no obvious explanations for. His videos are a good way to get a solid look at PA's mining and RR past in addition to the Pennsylvania countryside. I notice rail separation here. Likely the derailment cause in my opinion.
