What To Do With Railroad City?

Railroad City has evolved over the years to include any and all "things that go" and a range of "building materials" including tracks, blocks, lincoln logs, musical instruments, cardboard boxes, and prefab buildings.  It is Dexter's creative outlet where he can build a world and direct the interactions of its inhabitants.  Sometimes it makes me think that this is what I sounded like playing with my dollhouse as a kid (nice that boys' pretend worlds extends beyond the home). But Railroad City is continually creeping out of its designated corner. And, now, its designated corner is going to be temporarily given over to the Christmas tree. I have a feeling that we will all be living in Railroad City through the new year.
