quote:I've used the 650, 800 and 1000 card boxes for 0-27 engines and stock cars and they fit nicely with room for at least a layer of thin bubble wrap for the larger pieces. I don't know how they'd work for all cars, but the interior sizes are listed. There are also some boxes with more than one slot.
To repeat what Happy Pappy wrote about using bubble wrap, perhaps with stronger words:
Bubble wrap is known to permanently damage the finish of "O" gauge trains.
It certainly should not be in direct contact with any of your trains. I don't use it at all.
