After running these piggyback cars for the first time I have discovered that the trailers don't stay on the flat cars to well. I have been experimenting with making wheel chocks that  will better hold the trailers to the flat cars. These are 3D printed and mount to the slots on the flat car the same as the original wheel chocks.

I added a little hot glue to keep mine in place, you can always take it off if wanted.
