Well the attic has another pair of windows. One of which will have a air conditioner in it. Still all is not right yet. I need to put a door between the attic hallway and the train room. I will make a single pocket door between the two. I'll have to move the layout 2 1/2 feet to build the pocket part. I will get right on it.It will be a awhile before I can run my trains and make a movie. To much going on right now.
