Hi Ken,
It really is a deluxe plan .. but David and Carl and a few others did most of the work!
To answer your questions there is room to move the layout around as I mentioned in an earlier post .. also the way the yard tracks connect to the layout is very flexible and depends on how I position the layout . I also want to leave enough room for a comfortable sitting area with a couple of overstuffed chairs a table or two ..you get the idea.. Somwhere awhile back I made a scale drawing of the room including all doors..windows..poles etc. I'll have to try and find it and scan it in..or I guess I can duplicate it in RRT....
