As I sent to a friend (and fellow FTer) who works for CBS News in NYC a few days ago on this exact subjecft:

If nothing else cures you of 100% trust in the media, it’s watching them report on a topic you actually know something about. (and I say that as a journalism major...)

Drop speed from nearby 80 miles/hour to 30 miles/hour, I think that's a horrible design, a death trap on the track.
This addresses that assertion: https://www.wsj.com/articles/the-dea...ove-1513952658

If WSJ is putting up a paywall on that article, this one touches on the same topic: https://nypost.com/2017/12/22/train-...-deadly-curve/

Right, but it also doesn't have any 80mph stretches. Can they still speed? Sure. Could they hit an oncoming train? Possibly (but a yellow-followed-by-red signal is a little harder to miss than a small speed-restriction sign). But the chances of them accelerating to a speed where they can then hit a curve at 50mph over the rated speed and then topple off the track and a couple dozen feet down are pretty slim. The lack of PTC on the Point Defiance route is virtually a non-issue.
