TTX/FBOX #504634 “Forward Thinking” Repaint: TTX/FBOX #504634 is a remarkable replica of this one-of-a-kind paint scheme.  ExactRail’s model has unique artwork to represent all of the repaint details of the prototype—unique on all four sides, all the way around the car!  This includes some of the unique idiosyncrasies of the prototype—including the way in which the prototype logo sort-of “haphazardly” wraps across the ribs.
