Following the videos at Youtube the train symbol is #056, a generell train symbol for high&wide specials on the NS network i think...

Is Boeing or Triumph Aerospace the customer ? Where's their plant ? (Or are these cars from Florida, from Triumph Aerostructures ex(Vought Aircraft) @ Stuart, FL ?)

These go to Gulfstream in Savannah Ga.
