Hi all, I have been working on my layout plans for years and still have a few things to work out. I am going to build an around the walls layout in my 16X21 train room. I don't want duck-unders or access hatches. I am getting older and don't want to deal with access when I start to suffer from mobility issues when I get old. I am thinking about planning on a depth of three feet for my layout. I want to maximize the depth for plenty of scenery/building area and plenty of room for track, yet still want to easily reach the back of the layout for cleaning, maintenance, etc.
For those of you that have around the walls style layouts, what depth did you use, do you wish you had made it a different depth and what would you do different if your depth and height are not satisfactory for you?
