From what I saw- on the news clip that was from the news channel out in California- it was a large basketball size warehouse that had a bunch of larger O-Scale Lionel Train stuff. In the video clips that I saw, it looked like mostly larger scale stuff.
There was apparently a weekend only auction this past weekend for the stuff that was in this warehouse as well.
Someplace in Sacramento, California...
