Unless you have proof of any of this, its probably not true. We like to see hard facts, not word that gets scrambled through a game of telephone. Considering the FRA would have inspected the designs for the Nebraska plant before it started production in America, AND the fact that the FRA rejected the original design because it didn't meet safety standards, I would imagine they spotted that error, and that the trains come with PTC pre installed. Considering these trains are built in the 21st century, with modern microprocessors, a PTC unit shouldn't take up that much space, which I doubt it does.
