It's a matter of who has the misfortune of buying a" hidden" bad/defective casting.
Do the other scales have regular issues with crumbling trains as well?
Yep - I picked up a small lot of N scale items and got an InterMountain SD45 that had zinc pest do a number on its frame - I was put on a waiting list for over a year, and they eventually ran a new batch of models and Intermountain kindly sent me a replacement chassis.
