From the Chron via Rough & Tumble:
System can prevent train accidents, rail industry slow to adopt -- Faced with a huge increase in hazardous oil-carrying trains, California is urging quicker implementation of technology that would prevent train accidents caused by human error. Bill Lambrecht in the
San Francisco Chronicle -- 7/28/14
If I digest the somewhat random writing correctly, BNSF had PTC more than 10 years ago, but killed it to make more profits. AAR had a study describing the costs and benefits, for more than just safety, of PTC many years ago and killed (destroyed) it to make PTC harder to justify. And FRA is so completely in the pocket of the evil railroads that it won't enforce the law requiring PTC. Sounds like an Evil Thomas and Fat Cats conspiracy, right? The Press strikes again.
