Did they ever make a Norfolk Southern AC6000 in real life, not counting model?
No.
No.
NS doesn’t deviate much from the 4000hp range.
It is only within the past 6 months that the NS has orderd any AC engines at all.
NS does have ex-Conrail, 5,000hp SD80MACs.
These were the only AC, above 4,000hp locos on NS’s roster until recently.
