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
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.
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!
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.
@@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
@@legostar55 ruclips.net/video/HI6nUAFV13U/видео.html This is about all we have left in Ireland These two are 40 years old and still looking good. made by EMD I believe
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.
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!
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!
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.
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.
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,
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.
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
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
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.
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.
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.
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!!
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. ruclips.net/video/HI6nUAFV13U/видео.html
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
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…
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.
Even though there is road/grade separation at 17th St. Some people would say this line is a branch line, yet busy enough to have target signals (red, yellow, green) here & there. There's a branch line with occasional fast moving trains & target signals similar to this one going east from Denver to Topeka & sometimes along I-70. Or you could say the Colo to Kansas line & this Idaho line are slightly used mainlines. That line went through Manhattan, KS where I was living.
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.
MMMMM LOVE it cant get the lever past that 8 click... done it a couple of times in Australia on tourist railway at the start of grade, then sit there all the way in 8 going up a 42 grade.
GTA V gamer He was referring to the amount of throttle that these particular units were hopped up to in this video, not their max which is indeed 8. I heard it hit notch 6 around the :30 mark, and I think this is as high as it went in this video. Aside: The turbos on these units just absolutely sing a killer song.
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!!!!!
James, the air is coming from the main reservoir(s) on the locos. They're called "spitter" valves. They keep moisture from gathering in the bottom of the tanks & getting into the rest of the air system. The tanks have a stand alone pressure relief valve in case of overpressure. Have a good one.
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
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

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.

The clicking noise are air valves on the locomotive releasing.

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
It is a great UP line, almost served exclusively by SD40-2's from Pocatello, and a few stationed at Idaho Falls
