The prototype cars, being in passenger service, had 36" wheels, but
the wheels on the model weren't even 33". Replacement 36" Code 88
wheels wouldn't fit until I took the trucks apart and re-machined the
journal bearings. Then when I got the trucks back together I put the
car on the track to check coupler height (something I always do
before a project like this is very far along). Way too high off the
track, and no easy way to fix it. I had to cut down and re-bush the
truck mountings on the bolsters to get the car to ride at the correct
height - and then the screws that hold the side frames to the truck
bolsters interfered with the body bolsters and the wheels dragged on
the crossties. It took a good deal of filing (and, of course,
repainting) before those problems were corrected. ...


That is the reason some just move to Proto:87. When we attach
essentially non-scale trucks and couplers to nearly scale size car
bodies we run into clearance problems you describe. :-).

But Bob, I don't have similar problems with the RTR products of most
other manufacturers. I convert all my rolling stock to Code 88
wheels and Kadee scale couplers, and usually the most I have to do to
get coupler height correct is add one or two Kadee truck washers.
I'll hazard a guess: on the Walthers express reefers, the Chinese
ran into problems with coupler height and instead of fixing what was
wrong, they just put smaller wheels on it - smaller, even, than scale
33" wheels. The trouble started when I put the right diameter wheels
on the car.
