When I was little my father always did a Christmas layout on a 4x8 3/4 sheet of plywood. So I was raised with trains always running on a 4x8. Thank you for another great video! 👍
There is nothing wrong with a 4'x8'. Some of these empires that you referenced are never close to being finished, not that any layout is ever "finished." It is a double edged sword. I hope you had a good 4th of July.
