SCREAMING EMD'S! VERY LOUD!

[@floridianrailauto9032]

SD70M-2s are some of the best sounding engines (and best looking) out there

[@Fullsenddiesel]

What about the GP40'S and SD40'S?

[@floridianrailauto9032]

@@Fullsenddiesel Even though I love GP40s, they're pretty basic looking which isn't nessesarily a bad thing though

[@SteveO.1997]

You absolutely cannot beat that sound

[@Guillotines_For_Globalists]

Had a train come through like that earlier this year or last. Was so loud it made me jump up out of bed. Possibly much louder than this. People in the community were asking if it was some sort of siren. I thought it might have been a partially stuck horn, but this was exactly it, perhaps not quite the volume intensity but the sound itself was identical.

[@mbta1051]

It happens more frequently then you would think!! Many years ago there was a CSX SD70 (4787 I think) that terrorized all of Berkshire County MA. They initially thought it was a UFO, broken siren, stuck horn, or just a giant leaf blower as it could be heard throughout the county!

[@Goetterdaemmerung86]

I remember at one one place where I lived, the nearest railroad was at least a few km away, could hear this sound loud and clear, it’s amazing how much this sound carries.

[@chriswright6408]

hauntingly beautiful.

[@Crazeejay]

Awesome. I loved that sound!!

[@AlexanderTheSimmer]

1:59 Sounds like race car passing

[@Dorox97]

Great catch and sound

[@marycapok4247]

Awesome!

[@Luis-ys7fi]

Is that as a lot of weight of the wagons require more force and the engines of those locomotives work fast and that makes it move fast

[@dieseltrainfreek]

it's the cooling fan you can hear !

[@Kentucky_Trainiac]

dieseltrainfreek It's mainly the Turbocharger, but the cooling fans contribute to some of the noise.

[@AUSSIETRAINDRIVER]

Definitely mainly the turbocharger, the Globe aftermarket turbos have a distinct howl, but the fans do add to the noise also.

[@JaZu]

Yes, cooling fans. I really don’t understand why people think the turbos are causing that “howl” I have literally been on an overpass and witnessed them on start up.

[@floridianrailauto9032]

It's the alternator. Watch a video of some NS SD70s passing right next to the camera at a slow speed. You'll quickly realize that noise isn't coming from the exhaust and it's not coming from the radiator fans either

[@rooseveltmccarter6087]

That was fast.

[@FEROMODELISTAS]

Dynamic brakes sound
