Stopped by a sidewalk sale at a hobby shop and found an O Scaler running this donut car he'd created!
The car's owner had a really nice FM 4-Axle diesel with sound by Lionel in Central of Georgia colors. It's a fine looking unit and looks right at home on smaller radius curves.
The local donut shop makes these amazing chocolate cake donuts, affectionately known and self-titled as "Bearscat": https://www.bearscatbakehouse.com/
