Back to the intent of the topic... 🙂
I agree with Lad Nagurney, Peytonville is just calling for a model train running through it. There have been a couple installments of the commercial - even including a domed football stadium https://www.youtube.com/watch?v=vG9j1S9tAI4 - so hopefully a model train will be in a future one.
The close-ups look HO Scale to me, but I don't care, ANY model train being shown on the TV medium on a nationwide scale (pun intended) with two very recognizable people, whether one watches football or listens to country music or not, is a good thing in my book.
