A while back I picked up a 5 car set of never-used PRR HW cars from a certain auction site. I'm finally getting around to trying them out but find some alarming issues with these trucks. When I open their boxes, wheelsets come spilling out, the sideframes do not seem to want to hold them and I wonder if I should just replace them. Also, I purchased the "extra coach" from AM and it has four wheel trucks which do not seem to have an issue. Has anyone any insight on this problem and what did you do about it? Thanks.
