Allan, the layout will run along four walls. At the far left, the layout butts right up to the north wall of the utility room which is 10' long. Like my last layout, it will have a ~3' aisle in the center. There will be several duckunder locations along the front of the layout. The engine yard section will be 3' to 4' in width with a wider bump-out for the roundhouse. My old engine yard was 5' deep.
I have been kicking around the idea of some reverse loops with a (flat) crossover in the center of the layout. That might look pretty cool and could be the source of a few interesting sidings. Maybe someone might have a better idea?
I should probably show a rough outline of the benchwork edges.
