Edward Bridges posted a car that was in an unusual box, and had foam
at the ends (see photo section of group). I believe that his box is
missing the plastic holders. I have found this type of box in Atlas
sets. The plastic holders have a number on them (1, 2, 3, or 4).
#1 for reefers, 2 for gondolas, 3 for flat cars, and 4 for cabeese.
I have posted photos in the photo section of examples for 1, 2, and
3. You can see the number through the lid. I have also posted a
photo of the holders out of the box.
The plastic holders were terrible. They tend to slip-out of place.
Replacing the plastic holders with foam would to protect the car.
Otherwise, the plastic holders would slip, and the car would move
around in the box when transported.
