tompm's 2021 Do Something Challenge part 3

A quick update on the Bachmann Diner. I have pretty much given up on the car for now. From everything I can figure the solution will be removing the coupler box and replacing it with a body mounted one that does not swivel. At the moment I am not in the mood to deal with such drastic measures.

I found another Diner online for a reasonable price. Tonight I was changing out the hook and horn couplers and guess what? It has the same problem with the same coupler box as the one I already owned. Now I am wondering if there is some defect in the way these were assembled or designed.
