Well, the whole room is around 40 foot long, but the space for the trains is probably around 22-24 feet, there are the two areas at the ends that I won't have track. The one end will have my workbench and parts storage, the other end will have a TV and some seating. Of course, I have to find a spot for our secondary fridge, and it'll keep my beer cold and on-hand. 
Right before they sold the house, the previous owners put almost $100,000 into upgrading all sorts of stuff. All the bathrooms and kitchen are brand new. I didn't understand it as they just got market price for the unit anyway. I can only imagine that it REALLY needed it for some reason.
Here's a couple of shots of other parts of the house. All the floor covering everywhere has been replaced, amazing!
The light fixture has to go!
