Default EMD SD70 ACe

I have yet to see the new EMD SD70 ACe in action, and I wanted to know it sounds. Does she have the EMD whine at idle? How about the rumble at throttle up? I read that EMD has kept the 16-710 engine (with minor modifications) for this loco, and hope it sounds better than the loco looks!

I would assume it sounds similar to an SD70M.

They are VERY quiet. In fact, the first time I approached one, I was not sure it was running with the other units around making noise until the APU shut it down. Under load, they are still quiet. That was a major complaint with the early SD70's is that they were too loud.
