- Great Diesel Sound of Revving Engines! Two EMD SD40-2's, Union Pacific 3320 & 3723, with EMD 645 Prime Movers, Accelerate From Stop at Full Power with A Heavy Manifest Freight, while setting out and picking up cars at the yard just North of Downtown Idaho Falls, Idaho. EMD SD40-2 3320 is called a " Snoot" or a "Fast Forty", with a long short nose. A limited number were built for Union Pacific by EMD, and were geared for 80 mph, which meant they lead UP's Fastest Trains at One Time. Idaho Falls Idaho February 2011.

That low frequency rumble around notch 4 or so is the reason why I love the big EMD prime movers so much. And the SD40-2 is one of my absolute favorite locomotives of all time.
It's pretty neat when they're at almost the same RPM, you get that pulsating hum which is due to a "beat frequency" as the frequencies are nearly the same.
@@BenjaminEsposti yeah i love that pulsating sound but it will only live in my memories now days bcs i cant find any register of a SD40 doing this in particular
I absolutely love the sound
Is mine too. Miss the flared radiators.
The EMD 645E3's & 710G3A's or 710G3B's are the best sounding two stroke prime motors. It's just that the GP40-2's & SD40-2's have proved and retained for soo many years now how reliable and versatile these units are. I can't say the same for alot of modern EMD units,espiecally in terms of tractive effort and dynamic braking. I will personally add that I miss the MP15DC's/AC's and the 645E's which will always be my favorite road switchers.
Damn, listen to that beauty. A machine might not love you back, but they are certainly something to be appreciated.
Sebastian Roll you know she loves you when she goes full throttle
Planetesimal Planetoid A machine can love you back. just like a car, it does its job well if taken care of.
Well, I wouldn't say that though.
A well-maintained machine will run like a clockwork, and that's how it shows you it's love.
a machine DOES love you back lol
@@S7VolTagE *you know she loves you when she honks while going past you
or the driver is telling you to duck off, whichever is true xD
Oh man, I love that sound. The whisting sound along with that deep deep rumble just sounds so mean.
When I worked for NS as a yard switcher, I'd always use a good ole SD40-2! Railfans loved to watch me switch cars, cause I would switch cars like this guy was, loud and proud!
awesome EMD sounds
great sound especially starting at 2:38, but there no comparison to being next to one when it does one of these full powers. You can feel it in your body there's so much raw HP.
Yeah I can imagine,
Love listening to it with headphones,
Will probably never get the chance to hear or see one for real.
Live in Ireland,
Real diesel locomotive are almost gone,
Used to see them as a school kid , always stopped to listen.
andyvdb6,
There are still thousands like this one in operation here in the USA. There were about 3000 SD40-2's ever produced, but there are also other's like the SD70 types that have a very similar sound - in fact, they're even more powerful and have a larger cylinder displacement.
It is amazing. I live where this video was taken
@@andyvdb6 I live not too far from the east coast US Mainline so I see these things from time to time but I do have to drive about 20 minutes to see them

This is about all we have left in Ireland
These two are 40 years old and still looking good.
made by EMD I believe
I always get goosebumps hearing the hum-whistling sound of a locomotive! So much raw power.
and NEW EMD locomotives STILL sound this way. its good to see that that classic sound hasn't died away
About every diesel locomotive i've heard sounds the same. Idle, low RPM: Roots blower (two stroke Diesel engines need constant boost to keep cycling). High RPM: Roots blower disengages, large turbocharger (often not coming w/ wastegate, there's no need to in such large turbos, so they start building up boost only at fairly high RPM) starts spinning. If four stroke, there's still a battery of turbos of increasing size (sequential turbocharging), so, again, loud whine at all RPM ranges.
+TeraVolt Two stroke EMD units sound nothing like a 4 stroke diesel. EMD's came one of three ways:
Naturally Aspirated
Supercharged
Turbocharged
Turbo EMD units utilize a clutch to spin the turbo impeller at lower RPM. At higher RPM, the clutch disengages, and the impeller free-wheels.
GE and Alco units do not utilize a turbo clutch, so there is a little bit of turbo-lag in older units, which is why they smoked under certain conditions.
I agree Raja!
@Scott E But nowadays the 70ACe T4s utilize the 1010J engine, which is four stroke! 😁
Saw some OnionPacific locomotives today while waiting at a rail crossing (long, long consist, moving just above a fast walk) and those thundering things did not sound like this at all. They had a most definite thunderous noise, as well as a little *soot* for a moment upon acceleration.
Love the sound of the 645! That deep rumble mixed with the turbo spooling is just amazing.
Sounds kinda like a C-5's jet engines while taxiing on the runway
Im listening on my studio monitors and this sounds amazing. Love the low end rumble coming from these massive diesel engines.
Strange enough, I happen to be a professional guitarist, but I'm truly fascinated with the EMD sound. They never cease to amaze me. I wish I could hear more of that EMD sound, as apposed to what's out there now. I live not too far from railroad tracks. Keep those classic videos coming, chief!
The clicking noise are air valves on the locomotive releasing.
railjames I think you will find that the clicking sound was the water dumps on the air reservoirs.
Thank you gravelydon, I think you are correct.
gravelydon Could that be for climate reasons? More moist for example. Here in Europe (the Netherlands) i have never heard this. Even not on American made locomotives like the class 66 which is actualy a SD70 or SD80 as far as i know. Only shorter (20 metres) and 12 cilinders (EMD 12-710G3B) instead of 20 (EMD 20-710G3B), but with the same EMD 710 series 2 stroke diesel engine. I notiched on vids that all American loco's do this clicking but no one here in Europe. I wonder about this difference.
jpsholland I have had both railroaders and railfans tell me it is too keep moisture out of the air brake lines. I do think you are right as to climate reasons, as it seems to be on railroads that operate in cold climates.
jpsholland An example is that CSXT runs from the warm humid areas of Florida up to wintery Canada. In winter time, water will freeze in the brake pipes. That can result in a dangerous situation. Even just in Florida we can have upper 80°s in the south to below freezing in the northern parts of the state at the same time. When an air compressor compresses the air it raises its temperature but the moisture level goes up as moisture does not compress. When the compressed air cools, the moisture condenses out of the air. The air tanks then fill up slowly with water. You can have high humidity even in colder temps.
At the bottom of the reservoirs are drains. They can be operated a number of ways. Old way was a manual valve. Not the best but the cheapest way but relies on the crews to drain them regularly.
Another way is to use bucket valves. When the water gets above a certain point and air pressure drops thru use below a certain point, the valve opens and dumps the water in the line or tank. Then closes till the next cycle.
Yet another way is that when an air compressor kicks out at the pressure setting, the air operates an air operated dump valve. Closes after a preset drop.
And in more modern systems, the dump valves are electrically operated along with the compressor clutches.
How effective are the automatic systems, better than nothing but if there is a large enough air draw, you still can get water in the brake pipes. Like when a string of cars are pumped off after setting at a remote location. And when pressures in the cars drop for an application, the moisture will also condense out.
100 scfm of air at 80°F & 75% humidity compressed to 100 PSI and cooled back to 80° will dump over 5 gallons of water in an 8 hour day.
EMD 645, baby! That is the sound that made me fall in love with EMD when I was just a little tike.
EMD's getting the job done. Great video of the EMD switching and "no horns" so can hear the beauty of the 2 stroke singing.
You're right! I don't like those 'all horn and no engine sound' type of videos.
I clicked on this video for one purpose: to hear that EMD Rev. Its Beautiful!
The sound of a SD40-2 is amazing so much raw power
What a privilege it must be to operate one of these
Raw power. Love that sound. It's almost like a plane's jet engine.
It sort of is! A turbine is injecting air into the diesel engine, producing the jet noise.
Nothing beats the sound and feel of these 645E SD40 series locomotives pulling or pushing upgrade in notch 8. Forever etched in my mind 👍
I love that sound of EMD's SD40-2's!!! I just can't get enough of it! I used to live right across from the locomotive bypass and would hear the EMD's on daily basis.
This is music to the ears!!! Should be out on DVD.....long live EMD :)
The Best sound so far of a SD40-2 ❤️☺️ LOVE IT
This is great! Just how I remember them sounding when I lived near the tracks. Thanks for posting!
G'day from Australia.....We love them here too Nothing sounds as good as an EMD 645 SD 40-2....PURE..... BHP Billiton still use them as helpers I believe on the ore trains which are massive trains .....over 5km long regularly...Thanks for sharing The SD40-2 is king..Cheers,
love the sound of those SD40-2's
I hear this train acceleration sound at night time I live right next to a UP main line. I love this sound at night time and when the train is real long and heavy it shakes my house. It is the best sound in the world!
i will never get tired of the sounds thes engs made they had a sound of there own i miss working on the rail road
Fantastic shots !
Now that driver knows how to drive his loco's! Great sound ! Im not a EMD locofan but this sounds great! A Big like!
I used to spend a lot of time photographing trains on UP's Nampa-Pocatello division. This back in the early 80s when I was junior high age. Your video brought back some great memories of those dash twos.
Been looking for this high quality sound for a vert long time and I FINALLY FOUND IT here.
Still watching it in 2019 .. for motivation and inspiration ... Amazing power 😍
This has to be one of the best sounding videos on you-tube hands down. Great sound !
Out standing sound !!!! Captured video along with this amazing sound. Hat's off to you James.
Yes, I have been to the train show in Idaho Falls. Nice operating layouts.
Those are beautiful locos, they made history!
Nicolas, the EMD 645 does sound sweet!
The sound is spectacular! Must listen with headphones!!
I live by a short line track where the railroad (I&O) uses hand me down SD40-2s, sometimes they'll stop and start by my house! Sometimes we get hand me down tunnel motors locos from the West too! Glad I can hear that classic sound before they're scrapped or whatnot
Thank you! Amazing vid and sounds, awesome power!!
That's my favorite sounding prime mover. Awesome.
I love this video. Love the sound of those sd40-2's...
Thats music to my ears, I love trains!.
Awesome sound! This is exactly what I am tying to get when I chase.
Thanks
One of the best sounding locomotives.
The very definition of POWER... Epic sound!!
The crossings along this line in downtown IF used to have old, vintage, Griswold cantilevers sans gates with vintage mechanical bells, for a long time. But further west on Broadway, there's a very lightly used industrial siding (usually just a small locomotive & 1 or 2 cars only once during the middle of the night from what locals tell me) that had newer signals with gates long before the regular Butte-to-Pocatello line did (at the downtown crossings). Same with the Capital Ave. crossing
This sound, 645 prime mover, and loco will go down in railroad history.
I LOVE that sound!
sound quality is great, probably the best I ever heard on youtube
My father used to work at the LaGrange EMD plant and would take me there on family day. Always was amazed by the workings there.
the revs up ...sounds very good
one of my favourites!
one of the best videos on you tube... simple raw power! and OOOOHHHHH THAT SOUND
Used to love the SD40-2's on the Harvard subdivision of the old C&NW, they sound even better at night. Greatest locomotives ever built!
NICE Video, one of the best ones out there. Crisp clean, sound is excellent, can clearly hear the turbos whining, air pumps, etc.
Thanks! I remember this sound perfectly ,my father was a driver for 24 years! This sound is amazing for me, since i was a child =D
Greetings from Argentina.
Martincho Chevy Thanks. Glad you enjoyed!
Music to my ears!
Used to be a time when you got sick of seeing those dang SD-40s! No it is always awesome! Glad they are still roaming! Good video.
0:14 "Fellas...I need more turbo!" Excellent sound! Might work as a ringtone...
EMD 645 prime movers! Nice love the sounds!
Oh. How I love that Stop.. Then It revs up..SOUNDS AMAZING! :D great video!
A Snoot, wonderful, very nice video, thanks for sharing it with us.
I love it! When I was a kid, you'd hear the humming of the locos at night leaving the station. Those were F40PH though and they'd take off a little faster since they were hauling commuters, not freight.
Lisa, great EMD sound. Glad you enjoyed.
In Chicago, Metra uses EMD F40PH with HEP. It’s nice to listen to the engine spooling up when they enable HEP, but then you will hear the loud engine noise the rest of the ride as it runs constantly at notch 8.
Even coming here as a car guy, these sound epic
Justin Noker once a car guy, everything mechanical is music to your ears.
Man what a awesome sound. Curious as to what you're using to record the audio as it is catching the full-on lower-end of the audio registry as well as the high-end. Nice job.
What a great sound!
Best video for sound that I've found so far...
Super cool Sound with bass boosted 🤩
LOVE that sound.
Great clip I Love the sound of the EMD with TURBOs
Saved to my favorites 👍
Simply awesome!
Something I've often pondered is why we find engine noise so appealing, why we associate it with power. Of course surely everyone watching this video, myself included, are railfans, and we associate the sound with the incredible power of these locomotives, but I suspect there's something more visceral to it than that, something about deep ground-shaking rhythmic rumbling that feels enlivening to us, and engines (especially big ones) sound similar to that. Drums have been popular with humans since prehistory, and are often played in a rhythmic manner that sounds similar to engines, all existing long before any sort of engine ever existed. Or EDM music that also sounds somewhat similar. I suspect that you could play this - especially with a good bass setup - to someone who has never seen a locomotive or any other engine, and they'd still feel something visceral about this.
Very true,
As a kid I loved having to wait at a railroad crossing waiting for the diesel locomotive to pass, adoring the engine sound,
Unfortunately where I live they are not often seen these days.

I remember having 5 of these in our consists (Burlington Northern) and cutting off from our train and then walking from the last to the lead unit while under full dead stop acceleration.....and the need to lean way forward while negotiating the walkways. It was exciting stuff. Just glad I never had a turbo go "poof" while I was doing that!!!!!
I used to hear this sound while at work each morning, as the company I worked for was rail served. Also they would switch with the handbrakes set on the tanker cars, so that made some interesting noise, too…
mmmmmm that EMD sound just can't be beaten!!
Reminds me of in 1974 listening to trains pulling out of Paraburdoo western Australia 160 cars loaded with 110 ton of iron ore 3 loco,s up front 2 at rear still feel the vibrations 38 years on
Whenever I pass through eastern Idaho & I go by this line, whether it be in Idaho Falls or Blackfoot, I never see any moving trains or activity on the crossings on this line. Now of course on the main line that goes through Soda Springs, Pocatello, American Falls, etc, I always see trains on that line. I've also seen trains on the line that goes through Burley & Twin Falls. But still, I have to spend time in IF or Blackfoot to see trains passing through.
It's awesome I love this sound...... I've listened with extreme Bass....I love it...😍 I like to listen it one after one time, I would listen the whole day ‼️...👍👍
We used to take these for granted.
These sound awsome......10/10.....thanks for posting
3723 Brings back old memories,it was in helper service in Victorville Ca,from 1982-1986,
it was grouped with it sisters 3720,3721,&3722,I did have the pleaseure of riding 3723 &3722
down Cajon pass one evening in 1984, a trip I will tressure!!
One HELL OF AN AWESOME Catch !.
Great looking and sounding locomotives.
Awesome microphone. Thanks!
Awesome! Love those 645's:-D
That sound! In 1080P too. Thanks!
Fantastic! That driver knows how to handle them loco's! What a power!
In the winter they use the broom to clear snow from switch points.
makes sense, being the frogs couldn't be cleared by a simple front end snow plow.
Great vid...loved the sound!
by God what that locomotive sounds !!! i love that sound!!! Greetings from Argentina 🇦🇷
MAN, and WHAT GREAT SOUND!!!! Those turbochargers sound soooooooooo good singing in notch EIGHT!!!! Thank you for sharing!!!!!!
Total awesome sound
Superb humming sound 0f emd
Love that sound..I live in between CSX Frontier yard and NS Bison yard in the village of Sloan...Hear those old gals all night chanting that song
God they sound so powerful!!!
What a great sound! Not bad to look at either!
Great sound spoilt by the wind noise. I couldn't turn it up for full effect but certainly one of the better vids sound wise.
True Hi-Fi sound - Nice!
That Old line is cool, including the bridge over the Snake River. Once saw a Idaho Eastern GP 35 go down that line. But had no camera!
Love the sound. Notch 3 sounds the best to me. The RPMs are still low enough to make out each and every distinct thud from the cylinders but still high enough to hear the whine of the turbos
