Here are some photos of my indoor layout. It runs around the living room, ( The bridge in front of the fire place is Centered on the room, the fire place is not) Through the wall into our hall closet, then through the Bathroom, through our Bedroom closet, around our Bedroom then across the Hallway and into our Office then back in the living room. I still have a lot of work to do on it to finish it up, but the train runs good.
