Here's the dimensions of the table, feel free to offer any suggestions.
I'm actually thinking of moving the liftgate over a bit as I am already planning on an extension at the lower left, I have a 12 foot open area there. Moving the liftgate is no problem now as I just move modules around. The one narrow section at the middle top will get a angled segment to allow more room to make the curves fit there.
This is the whole basement plan. The red is where the current layout will go, and it will also fill that back cavity, too lazy to draw that shape. The green is what I'm going to add for a yard, so I'll move the liftgate over about 4 feet to keep out of the way. The white triangle is also bench for the tracks to the yard.
