Okay, so I got the go ahead to claim some sacred space in the house as mine and this is what I came up with. We're talking an N scale L. The bottom leg is 9 feet long and the top leg is 7 feet with the width of both legs at 2'4. The minimum radius is 9-3/4". I'm not much into operations but do like to piddle around every once in a while and so do not have a lot of industries but I have space for future industry additions. The layout will be capable of running two trains independently with one mainline staying at table level while the other mainline will be a folded dog bone. While I have never attempted this before, I plan on going DCC. There will be a large canyon on the upper leg with lots of steel truss and girder bridges. My era... hmmm..... let's just say early diesel on. I always see other plans on here and see them get great criticism and so thought I would give it a go. Wha'cha think? Oh, I forgot to mention that the height of the main level will be 36" due to a window in the room and the highest track level will be at 44". Thanks all.
