GPs are 4 axle and SDs are 6. That I know but from what I looked up, SD9s and 7s are very similar but one of the big spotting differences is where the class lights are positioned. Looking back at a picture of the box this is indeed an SD9. Also funny how mine fits right into your roster!
I'm not up on the spotting features of the SD7 vs. SD9, but I have noticed SD7's have a ladder on both sides of the front high hood and the SD9 only has 1 ladder.

Actually the ladder thing varies from road to road, and time frame to time frame.
I'm not an expert on every variation, on every road, but on the B&O alone I can show you photos of every possible variation of those ladder positions or lack thereof.
