Who told you that? Did you give any thought to what you wrote?
You have better ears than I have. I didn't hear any wheels squealing and even if I did, that is how Hi-Ad units get their pulling power. The traction control allows for a certain amount of slippage in order to achieve more pulling power.
"Joe: YN2 means Yellow Nose version 2." = Railfan lingo.
Jim, I was just going by what I heard. I've heard when the wheels make a squeal sound on the engines, and it's a straight track, means the units wheels are slipping. Now I could be wrong, but that's what I thought it was. As for the sound, it's so faint in the video, but when I was there in person you could hear it. It wasn't loud, but still I could hear it. As for YN2 Yellow Nose 2. Yea, that's what I've always known how to decipher the different CSX paint schemes. YN1 was known as the Stealth Paint Scheme. YN2 is what's in the video. YN3 is the dark blue with the CSX yellow and YN3b is the Boxcar Logo's. But, most of my life, that's what I've always heard for CSX units on how to know the different CSX paint schemes.
And yes, to walk a whole train, say if something happened at the rear and say the conductor has to walk all the way to the end, now I'm just saying this, I would wait till another train passing on the other track went by and he or she could get picked up and be taken down and once another train coming back the other direction would come to pick him or her up and take them back up to the front of the train. Now I'm just saying. I know this doesn't happen often, but that's just an idea.
