Really? I wonder why they did that. I'd think that if they wanted accurate sounds from American freight locomotives that they'd jump on that. Either way, all I know is that they DO need to work on their sounds of the horns and prime movers 'cause the AC44CW sounds just awful. To me, the prime mover sounds more "whiny" and thin rather than loud, low and rumbly like it should be. Anyone who's heard an American diesel-electric loco in person will tell you that you hear it MILES before actually seeing it.
