So if the 53 ft. long that Claire saw earlier today (above) was a domestic box at 102" = 8’-6" wide, and the 40 ft. long box underneath was an ISO box at 96" = 8’-0" wide, then the 53’ would overhang the ISO by about 3" on each side, and by about 6’6" on each end, correct ?
Hi Paul,
Yes they would overhang about as much as you calculated. These photos (especially the 3rd) show a bit of that effect.

Next time I get out on the yard at work, I’ll see if I can snag a photo of the double aperature under the boxes. Its a pretty cool casting. One thing related to the casting that most folks will never see is an IBC hung up under a box. Sometime the mechanism (rod) that turns the 2 bayonettes on the IBC gets twisted and the IBC hangs onto the bottom aperature of the top box. It can hang there even after the box is on a chassis. If a driver isn’t careful, he can leave the rail ramp that way and get on the street with that 13 lb steel monster hanging there and waiting to drop. I know of 2 instances where that happened. 1 resulted in a fatality, the other just vehicle damage to a following van.
I get my donut $ helping make those big boxes move, so I have a little extra access to equipment and insight… hence the handle.
If one pays attention to the train that starts moving toward the camera at 2 mins 30 sec into the following clip, you will see a variety of stack mounting…including one of a 53 foot on the bottom and a 48 foot on top.

Great couterexample! I’ve never seen one. It makes sense because the 53’ and the 48’ are both domestic.
Exactly right Claire - both domestic.
