Further update re Sally the Yard Goat: I unleashed her onto the main line where she traveled passed the Popsicle Stick ball parks, then back onto her siding, and all was well. She also hauled 3 hoppers with coal loads during this run.
Later on, time permitting, I will post a video showing this positive new development in the continuing saga of - Sally the Yard Goat.
LOL, Arnold
