Lionel O Gauge 8568 "Preamble Express" F3a diesel locomotive in box.  Train has a strip of missing/flaked paint in the channel of a roof panel edge.  White is whiter than normal, but does have some very light signs of age and handling.  Train looks lower C7 with very light run time.  Box shows very light shelf wear to surface, bright, clean, square and solid.  Excellent styrofoam.
