Great video! That is a sad sound to hear, as this howling noise (known as the EMD Turbo Howl) is a bad sign of a turbocharger about to call it quits on an EMD 710 Engine, this has been happening for SD70ACCs and SD70M-2s and SD70ACes for a while now, hopefully this won't be an issue in the future, regardless of the locomotive dying, the sound is a heavenly noise to hear, it is very rare, and to be cherished, you are lucky to hear that, wonderful video man! It is still hearable today from the SD70 rebuilds into SD70ACCs
So loud it almost drowns out the horns! I’d say it’s the fans, but they’re not typically THAT loud I don’t think, maybe there’s a problem with bearings? Either way it’s very interesting and eerie sounding
@@NS6677 hmmmm, I’m hearing some say that when locomotives howl like this it’s an out of balance turbo, deposits maybe cause it, and thus the turbo vibrates like crazy. Makes sense I guess, reminds me when I’d use my Dremel with a cutting disc, if I set the rpm too high, it’d vibrate like crazy and make an awful and loud noise.
Where I'm standing, you wouldn't be seeing much. Couple of trees in the way. I always stand on the embankment. Best place for Videos and Pictures. No where to step back further without being on a big dirt hill. I mainly take stills and video is my secondary thing.
You can hear the pure power in that SD70 Trying its hardest!

Not a turbo howl. It’s the main generator howling.
If there was ever a horror movie made about a killer train, that would be the perfect sound that it's coming.
Agree with you 100% sir
Lol
2572 is sure a screamer, I've caught it at Alley Hill, you could here it for miles, great video!
I bet the people at horseshoe curve we’re like what the heck is that noise when they heard it out in the distance.
man than likely! Plus that Thunderstorm moving in made things better.
That is an absolute symphony!

Best sound hearing that at the Horseshoe. Won't hear that engine again. NS retired it. Not exactly sure what the noise is

Those tracks look so good
Amazing sound! Feel bad for the crew though, having to sit in the thing for 12 hours while it does it.
Usually only sounds that open the throttle was wide open. And it didn't last too long with 5 cars! Haha.
Bad fan bearings.
GO EMD!!!
That sound might be heard 20+ or more miles in an open area
Probably, also if there is wind I'd imagine it'd carry quite far indeed
Must be a problem with the turbo charger, or motor fans! What a short freight train!
Awesome video Marc! That SD70 sounds awesome solo up Horseshoe!
Something sounds wrong with the fans for the turbo, though can't be sure. It's a familiar sound for locos with an EMD710.
gorgeous scenery !
You actually saw this engine earlier this year, when it was leading 23Z in February, the 2572
Just subscribed, you do great work
Thank you. Glad you enjoy everything.
dude! you should have zoomed in all the way to the curve where you could catch a closeup of the locomotive rounding the corner!!

A True Gem with an awesome sound!
How do you get to that spot at horseshoe curve?
Lots of hiking up the side of the mountain from the opposite side of the tunnel from the Park.
Ok. Thanks!
Creepy sound..
Cool! Sounds different though!
Nice catch Marc
Cool. Where is this located at?
Locations at MP 225 in Tipton PA and Horseshoe Curve in Altoona PA
@@NS6677 Thanks. I may have to visit that spot one day. It would be a long drive, but worth it.
To bad that lead SD70 is a thing of the past now :( Great catch & sound :)
Always why I told people, "Go out while the old classic stuff is still out there".
Cars can go on tracks?
Railroad cars........
NS6677 I meant pickup trucks
Definitely hauling ass.
its short
as it says in the description..
DC Traction problems, need to invest in more A/C Power to avoid this.
Creepy 😮🤮😵🤢
Hows that?
@@NS6677😳really insane
Badddddd 😳
