Well, when I finally had a decent trainroom, my first step was to just start unpacking stuff and putting it on the first set of shelves I put up, those were in the stairway to the trainroom.
Unfortunately, even with all the additional shelves I've since erected, there are countless boxes of stuff under the layout, in the closets, and in the shelves in the garage! I hope I live long enough to unpack them all!
