I believe some CSX units have 8521's style of truck, too. Mr Nutbar makes an interesting point -- there used to be a definite spotting difference between the 9-44CW and the AC4400, which was what I think is called the inverter box behind the cab on the conductor's side. Earlier 9-44CWs did not have this box, and instead had an air conditioner here:
From remarks on the West Coast Rail Forums and elsewhere, it sounds as if GE would like to standardize on all AC locos. I would guess that putting the inverter box on the 9-44CW but not using it would be a step in that direction, and all I can think is that this took place late in 9-44 production.
