Train under the Christmas tree

It was always O scale in our house.. but I love all trains.. I think theres something relaxing and theraputic about them... lol
The first year we had it set up it took us a day or two to convince our Irish Setter that it was not her toy. A few years once we had it all set up we left the train running til we took the tree down.
My Dad built a layout that took up one room in the basement. Had 3 layers. An AFX track as well. He had it configured so you could run 3 different trains at once, park on a section of track and turn it off. Took My Dad and my Uncle George a couple of weekends to wire it all up. It had 4 different transformers. Of course, it started out as my Christmas present one year. Once he got it set up he locked the door to the room it was in when he was not home.....and even when he was he would not let me in that room....
