He was most likely if he fled the scene and was headed in a southerly direction. Happens all the time in border states like Texas. Insurance? We don't need no feelthy stinkin' insurance or CDL (Commercial Drivers License).
I did not see any comments about the engineer’s condition or status after the collision. It would be interesting to hear what he has to say.
Locomotive engineers have to have nerves of steel knowing that they cannot stop a speeding locomotive in a very short distance. They dread the day when they see an impending collision and must decide whether to ride it out or abandon the cab (jump and run). Neither option is very good. Thank G_D the truck was not loaded with anything explosive or flammable.
