Nice video Trav, you caught a lot of action at many locations. I recognize many of them. Be safe, happy rail fanning. Ron//

[@TrainTrackTrav]

Thank you, Ron! Lot's of awesome locations to film the mighty ACes.

[@GarrettsTrains95]

The ACe is amazing

[@TrainTrackTrav]

I agree. The best part is that they'll be around for quite some time. We still have many more years to enjoy them!

So what’s the deal with the one at 6:41? Sounds like a stuck horn.

[@TrainTrackTrav]

Not a stuck horn. That noise was coming from the engine compartment. My best guess is that it's the turbo bearing ready to call it quits.

[@paulspomer16]

@@TrainTrackTrav Hmm that could be but not sure. One thing that leads me to believe it was the horn was that the pitch and volume didn’t fluctuate. It stayed constant the whole time. It was also VERY loud and I don’t think a bad turbo bearing could be THAT loud. And there’s no way to tell if the sound was coming from the engine bay or not from just a video.

[@danielsebring6220]

@@paulspomer16 turbo bearing howl is quite common in the SD70 series, and happens in other locos too, but not as often. I will agree that does sound like a horn, though, because the principles are similar. You have a turbo shaft that's spinning at about 18-20,000 RPM. If there is an imbalance from the bearings, or carbon deposits, the shaft vibrates, creating a frequency. The design of the exhaust stack amplifies this, which causes the sound to carry the way it does. Hope this helps!

[@orbitsrailfanvids]

@@paulspomer16 its a blown turbo.

[@VisionsofEd]
