Thanks folks.
My wife actually bought the brown footrest, last year, to stake out more space. Also, once upon a time, there was a hutch on the left. When my wife wanted it moved, I wasn't expecting it to be replaced with the 2 units (I covet THAT space. I could get another loop, if that was in play). I can't complain though, she has supported each expansion. She made the hills. She sets up the village.
The empty space, where the new loop extends, was to leave the dog a path to the window. As long as I dont leave trains stopped under the window, it's worked out well. I think she will step through this track. We just don't want her thinking the easier path is through the farm, on the right.
As to expanding..... I can't have more floor space. I think a double raised loop in front of the fireplace will block too much, so I might be done. As to all year... We used to start Thanksgiving weekend and break it down on or before little Christmas. Lately it's been making late January and one year early Feb, because family was coming in to see it. I'm close to getting a room, but it will be effectively smaller, than this space.
I wish I could find 2006 - 2008. 06 and 07 was the original loco with 3 cars on 027. 08 was the year it was replaced by an MTH set and Realtrax.
