"Sumwalt said that positive train control -- a GPS-based safety system that can automatically slow or stop trains -- could have prevented the accident."

For the love of God, what the hell is it going to take to make this system mandatory? Why do they keep putting it off? (Mostly rhetorical. I know why, but I'm still pissed off about it.)

Well when you have your passenger trains at the mercy of freight companies....

My one Amtrak trip may be our last unless something major changes. We loved the idea, but when I found out that it was so rough and slow because we were second class to the freight trains that owned the tracks, it’s just not worth it now.

Super important to note that they were on CSX tracks with CSX dispatchers for this incident. It's not clear if PTC would have helped.
