Funny thing too is the GE's of equivalent power redline at abound 1050 RPM if I remember correctly. But they're 4 stroke so they sound like they're going slower!
@@BenjaminEsposti bear in mind GEVO engines have quite a bit more displacement for this reason. A 2 stroke will always have a better power to weight ratio than an equivalent four stroke of the same displacement as a result of two power strokes per single four stroke cycle with a single power stroke and one exhuast stroke. Though thanks to the much higher expansion ratios acheived in four stroke, the efficiency is tremendously higher. It's all about trade offs. Here it's about power density vs carnot efficiency.
@@scenicdepictionsofchicagolife.... Actually, The power to displacement ratio is Much higher than on comparable output 4 cycles (as You, pointed out), regardless of overall displacement. You have to consider (which 95%+ of "laypeople" do Not) also, that on these engines, the actual Power stroke is just slightly HALF, of the overall stroke length, before the exhaust valves begin to lift and scavenging begins. They produce (basically) the same output numbers (hp/torque) as the 4 cycles... on generally 33% Less, Total engine displacement. Also, I'm NOT "directing" this comment/reply, to yourself (SDofCL), as much as I'm "adding" to yours for the benefit of those who do not really understand the subject..... as "abbreviated" as our comments are, in comparison to the whole.
EMD engines just OWN all other prime movers!!! 4-strokes are ok, but they chug like a washing machine that's out of balance. God I love EMDs! I just hope caterpillar keeps their engines out of them. It would just make me cry to see them get rid of 2-strokes engines! I could listen to these all day long. My only complaint on these later model 710 engines is they muffle them a little too much for my liking. The 645s exhaust was less restrictive. A 710 engine w/645's plumbing = HEAVEN! Damn EPA !!
I know this is a 5 years old post, but I would like to point out that 2-stroke engines cannot be fuel efficient and make low carbon emission in their combustion cycle. Like it or not, 4-stroke is going to be mainstream for the upcoming Tier 4 regulation. But then again, still in many other countries, that 2-stroke EMD 710 would probably still the star of EMD's lineup. As well as their legendary reliability. So don't think the 2T will see going away anytime soon.
@@Xyb3rTeCh the entire concept of 'tier 4' emissions regulation is a fraud. Air pollution levels in the US are at 'background' , ie pre-industrial levels now, and have been since the early 90's. Cleaner and cleaner engines will have NO EFFECT on air quality whatsoever. The rationale is that it's being done on 'principal'.
@@jimrennison1 You're right on target, a big con job! Plus, Class 1 train traffic in the US is at an all-time low while trucks clog up every highway in sight, and they want to talk about the environment? It's all one huge scheme to boost trucks, the big wigs in the EPA, truck companies, and more don't care about the environment. We're all being screwed thanks to their evil greed.
the v16 EMD's are the best sounding prime mover to ever hit the rails. That engineer doesn't waste any time putting the "pedal to the floor" and tearing out of there. Nice good sound depth too. Good recording. That rumble is just lost on a lot of videos. Hard to catch but for me it's the soul of these things.
I can't stop coming back to this video. The sound of an EMD 710 is just the most memorable diesel engine song to me, with it's high-revving jet engine sound (I know, EMD 2-cycles predate jet engines) and deep thunderous rumble. Long live EMD!
This is definately one of the best EMD demos. Earth shattering vibrations on notch up then the sound of the Auxiliary fan and Turbocharger no full notch. That howling sounds so badass.
Its an amazing sound to hear through your device, but to live it in person is a whole different story. When you are there you can feel that rumble course through your insides and if you're near a metal structure, it may even give it a good rattle just by passing by.
Imagine working on a tugboat with 2 EMD 645-20 E7B's working full ahead @ 800rpm - it's like having 2 locomotives in your living room! Crowley built 25 "INVADER" Class twin-screw 140' deep water line-haul tugs at McDermott in Morgan City, LA. in the 70's with twin EMD 645-20 turbos. These were the finest long haul tugs in the world at the time. We towed 450' x 100' oil barges with crude from Valdez to Seattle, The Bay Area, and Long Beach constantly with these great boats.
@megs905 They are not necessarily in Notch 8. All EMD's with 710's rev up to full rpm's as soon as you hit Notch 6. Then after about 15-20secs if the throttle hasnt been increased, they idle back down to Notch 6. You will hear that happen around 2:25 as they idle down.
You should live where I do and then you'd hear beautiful GE 4-stroke/cycle music all day long and you'd love it. Hard to compare a 2-stroke/cycle with a 4 stroke/cycle as well. The GE's sound beefier but quieter than the typical EMD 710 fare when they're coming up the hill by my house and that's the sound of a lot less #1 diesel being expended. A real treat for me is hearing the rare turbocharged 645E3 go by. I grew up on Dash-2's and I sure miss them.
TheTheratfarmer Actually, a 16-710 produces 4300 horsepower at the crank. A GEVO-12 produces 4400 at the crank with a quarter less jugs. The 1010J looks interesting, though - 4600 horses at the crank with twelve jugs.
Awesome!! that is music to my ears!! I've been a huge EMD fan for years. Nothing beats the sound of turbo 645!! If you catch some SD40-2W doing the same thing...UPLOAD!!! Cheers, WCR
An EMD 710 would be awesome down here in New Zealand. Unfortunately they probably wouldn't fit into our trains. We use EMD G18C and G22AR models down here, built by Clyde Engineering in Australia. The G18s used to use the 567 series but were then retrofitted to use the 'blown 645 seires. The G22s initially used a blown 645 but then converted to a turbo when NZR realised they needed more grunt. At Notch 8 they sound spectacular and man are they loud!
Very cool yeah! For those who like 645s turbocharged, check the Metra MP36PH-3S. Since the prime mover drives a huge alternator for HEP, and HEP power is generated from 3rd notch and up, the sound has more lower frequencies than the F40PH (screamer) having to stay at high speed for HEP. Enjoy!
mrbillmacneill It's either headed toward Prince Rupert or Vancouver. Next home terminals going west are Prince George and Fruitloops, and crews trade off halfway between those - so either Blue River or McBride.
At notch eight she sounds like the 071 class loco that we have here in Ireland. They're used on freight mostly but they also serve other duties when needed.
Check out 36 thousand horses.m4v! on youtube It is about the Rogers pusher terminal in BC when Cp Rail used up to 12 SD40-2 locomotives to push west bound trains up the east side of the Selkirk mountains so they could go on their own through the connaught tunnel!! You will enjoy it!!!
I hear ya. The SD60s seem to have the best unrestricted 710 sounds. You can hear the turbos whining on them at notch 8 which you don't seem to get as much on the newer SD70s
Love it....the EMD 2-cycle sound was always one of the best. There is always a preponderance of loud fan (or turbo blade) humming with 710's...what gives. Still give the edge to a trio of unmuffled SD-40's storming up Keating Summit, but I'll surely take this. Five stars.
If you like the turbo 645, then you should have a look to my CN532 (at 4:30) or my CN 534 (2:32) videos. I think you will like my video "NSB Di4 ..." too. There you can see a loco, Germany built for Norways state railway. It's powered by the 16-645 E3B prime mover.
The rumbling noise is from the engine, the white-noise and whining sounds are from the turbo, and also some of the white-noise sounds are from the cooling fans. I don't think the traction motors are loud enough to be heard over the engine noise.

@UP5140SD70M I like the sound of a good GE chug, and they seem to have more of a personality than EMD. I'm not saying that because im a GE fan, but they just do.
