Richard helped me confirm that the trucks on the ERIE's "PS2*" hoppers, visible here:

http://www.rr-fallenflags.org/el/frt/erie21800b.jpg

Are 70 ton ASF A-3 "Ride Control" with roller bearings.

But he deferred on this question:
B) what model comes closest to that?
Saying:

I'm not much help here, as roller bearing trucks were developed long after the era I model. I

took a quick look on the

internet at Accurail, Atlas, Walthers, etc. and none of them appear to be quite right. You need

to confer with a

modeler

who knows more about RB trucks.

Well, I did the same looking around, but have not found a good candidate either. The Kato ASF A-3
has "solid" bearings, not roller bearing (or at least the ones I have do).

Is there a commercially available ASF A-3 with roller bearings available?

Thanks for any assistance.

[BTW, the trucks Athearn supplied on these cars, which this list helped me find a couple of weeks
ago, are RB trucks, but are not correct, thus this request.]

* Yes, Ben, I know they're not "real" PS2s.
