The old Blue Box model was not overly correct for either version if I recall, labeled as a GP9 but closer to being a late production GP7 if my memory is correct.

I seem to recall that Blue Box models were packaged such that the "GP-9" models had dynamic brakes, and the "GP-7" models did not. However, the body was the same except for the brake blister (or not), and was not completely correct for either locomotive.

Yes, the Blue Box GP-7 and GP-9 used the same chassis.

Can anyone tell me if Athearn GP7s and 9s ran on the same chassis?

 

Are you asking about the current GENESIS model or the old Blue Box or Ready to Roll model?

Considering the degree of similarity of the prototypes, I would think the GENESIS models would be on the same chassis. But I don't own any to check. All my GP units are Proto2000.

The old Blue Box model was not overly correct for either version if I recall, labeled as a GP9 but closer to being a late production GP7 if my memory is correct. Since only one shell was ever offered for the Blue Box model, yes they all had the same chassis - that is at any specific time, because the drive did go thru a number of up grades over the many years it was produced.

Being quite uneducated about the GP7 and 9 versions, how does the same chassis matter?

Yes, ironically, just like the prototypes.
