Many years ago, all loads leaving WATMA were shipped TOFC.
The meant every load was loaded onto a railroad flatcar.
Be means of a giant front end loader, that picked up the whole trailer, tilted it back and then placed in on the flatcar.
We were getting so many complaints that we started taking pictures of every load, to prove it was done right.
The only way to halt the complaints was to spend the time to lock every load in tight.
I even placed smaller parcels at the top of each wall, forcing the top outer skin of the trailer to buckled outwards.
