Saw this interesting Twitter thread with some data yesterday. In fact it doesn't seem derailments are unusually high compared with history. It seems they may even be decreasing.

The complaints about precision scheduled railroading are valid though. Every foamer has been talking about it. And again as your link shows this derailment (like many) had absolutely nothing to do with the overturning of the breaking rule that has frustratingly grabbed everyone's attention. (I guess everyone loves a simplistic explanation that blames government officials even if it's wrong.)
