Ah, yes, I guess NS's response to AC current is "what's that?"
Of course, aren't the eastern roads the only ones to have 80MACs?
What's the real difference btw them and 90MACs?
CR was the only road to order the 80MACs. They picked up 28, then opted for the 2 demonstrators. CR actually did order another 30, but NS and CSX had hissyfits and the order was changed to 22 SD70s for NS and 15 SD70MACs for CSX.
The only external difference between the 80MAC and 90MAC is the rear sandbox on the 90MAC extends the entire height from the walkway to the dynamic brake fan. The 80MAC has a shorter sandbox to allow for the trademark CR class lights.
