Boy, does this topic touch a nerve!
I live in California so no basement. I have a 4x8’ layout squeezed in our extra bedroom.
I have stuff stored away from when we moved out here from Ohio eleven years ago that I have never touched since.
I have sold tons of stuff over the years - Ebay - which my wife is active on. She nags me constantly about selling my trains. She is right, of course, but still...
I have a rather complete PW collection if you count original and remakes. I’d hate to part with this childhood memory stuff. Recently, I have been on a scale rolling stock kick, so now I have a large bunch of that. Neat looking pieces!
I sell off things I just “had to have” but never used to make room for new stuff I “have to have” but probably won't use, either. I dunno. One thing I am determined to do is buy only a few roadnames from now on. Northwestern lines.
I dump rolling stock boxes for the most part nowadays but keep engine boxes. Box storage is a terrible problem. I keep all my trains in plastic tubs with content listed on paper taped to the sides which is helpful. Necessary, actually.
I share a storage locker with my son which has been a lifesaver - keep the big set boxes over there. My garage shelves are packed with boxes as well.
And as bad as it is, it used to be worse storage-wise. Now it is at least static because I have no choice. One comes in, one must go out.
At least Lionel is helping me out by making things I either can’t afford or am not interested in. I’m getting two boxcars from their newest catalog.
Now I just have to figure out two cars to sell to make room.
Cursed by an abundance of riches. Truly.
