Ran trains with my son. We got out a few packs of trees, the kind you get for holiday village setups, and he placed them around the layout. I also have a bunch of plasticville buildings on the layout and he changes where they go depending on his mood.
He is really getting into this layout, and I made sure there is nothing on it that would break my heart if it breaks. I love to let him explore how he wants things set up and he loves to play with the figures that came with the polar express with the trains.
