South of Dallas north of Corsicana. This is the old SP/Houston Texas Central line. http://www.wfaa.com/media/cinematic/gallery/74526078/train-derails-in-navarro-county-flooding/
The crew had stopped the train when they saw the trestle was coming apart but the water washed the ballast out from under them causing the locomotives to roll over. The crew was rescued with a boat.
It's good that crew is safe. But this also clearly demonstrates a very negative aspect of these coupling systems, a the entire train is sucked in by pullover. That's a lot of additional damage, time and cost.
One "news" commentator on TV stated that "both conductors escaped injury." No engineer? Kidding, I know the news people don't know about crewing.
I remember on of a college kids who was a car host/attendant on the Rocky Mountaineer trip that my wife and I took last year. He was on the car PA pointing out a trackside monument we were passing honoring the casualties in a collision between two trains along the Frasier River in British Columbia. He was trying to use all the politically correct terminology while describing the train crew. Engineer was still engineer but he called the fireman the gender neutral term "Fire Fighter". All us old timers cracked up and he could not figure out why.
