After my Dad passed away almost 12 years ago , I took trains that had been in storage for 30 years out of his attic.
They had been wrapped in newspaper from the 1970's and 80's and placed in cardboard boxes. To my surprise being the attic had zero heat or a/c ,the trains an accessories had little to no rust , corrosion or oxidation .
But I have stored a lot of items here at my house for the last 25+ years and have found the plastic foot lockers you can buy at Walmart holds quite a few trains . Then I use clear tissue paper then bubble wrap on the trains.
I put cardboard between each level of trains in the box to minimize the pressure of the weight that might create damage.
I store my trains in a finished basement , but still use a dehumidifier . It does make the room subject to more dust than usual , but remember moisture and excessive heat are enemies to your trains .
Oh and a avoid pushing the containers or boxes up against the block walls of a basement if you store them there, lesson learned boxes will over an extended period of time draw moisture out of those blocks no matter how dry you basement is.
I did have some trains in a cabinet that were in cardboard boxes that some how got pushed up against the block walls and caused minor surface rust on some wheels , not a big issue but beware.
