Nice research...I was wondering why I hadn't spotted NS using it much if at all. They have some other color schemes in the flamethrower style that I have seen on video of some of their trains.
Nice video. I heard rumors that one of the reasons it failed was be because it was improperly transported and the wheels locked up resulting in flat spots.
