Warming up CSXT 8361 4/10/13 Great EMD 645 sound!!!

[@christophermattox3972]

I love the SD 40-2 EMD’s. The best sound ever. I had a dream about me driving one. I am blind and yes I love trains.

[@Kai01191-t]

Keep up the love man, I wish you the best

[@christophermattox3972]

I will.

[@Shane-Singleton]

That low frequency rumble at notch 2-3 is what I love most about the big EMD 2-stroke prime movers.

[@lassekristensen385]

I does have an incredible sound! No doubt- but WAUV! shit these old machines pollute! Its quite disgusting.... 2stroke is ANCIENT at this point and extremally dirty and un-healthy. Its gonna get exciting that many new US trains are getting the Siemens with a 4 stroke 95l quad turbo Cummings. You cant even see the smoke comming out of those and they have 4400 HP.

[@QuinnDickinson2610]

2:36 The sound of pure American Pride!

[@easternroutemainlinevideos6823]

Agreed

[@EdmontonRails]

+Quinn Dickinson what about the CP SD40-2s roaring up the rocky mountains.

[@privateerbouncher9622]

Then you should also listen to this video :) kzbin.info/www/bejne/fmO4YoF5eb2Vlc0 It's the Danish variant of SD40's ;) BTW Skip to 2:50 in the video, then hear the pride of EMD/GM ;)

[@TrainTrackTrav]

Tier -2. LOVE IT! She even did the EMD bark at 2:42! So cool. Awesome catch.

[@Shane-Singleton]

What's happening when it does that? Some kind of pre-detonation?

[@TrainTrackTrav]

Sorry for the late response. I believe that sound is caused by the turbocharger momentarily stalling.

[@silicon212]

It's turbo surge, or 'turbo bark'. Most common cause is a plugged air filter.

[@railroadrick6060]

There should be a good petition where a 12 hour version of this is uploaded 😊. Certainly, it would help all of us with 12 hour shifts. I support it.

[@dylanruppert4547]

The best EMD sound ever made!

[@MilePost106]

Wish this sound was for 8 hours! I can never get enough of this!!!!!

[@hakeemsd70m]

That 2-stroke 645 prime mover means buisness. What beautiful, mechanic instrumental music. Thanks for sharing.

[@SpeakerPolice]

This guy is pumping up air! EDIT: He's got major turbo or overrun clutch issues. That turbo is having difficulty keeping up properly, hence the belching black exhaust at some points.

[@silicon212]

It probably has a plugged air intake filter. That will also cause a surge condition, leading to the 'bark'.

[@pootispiker2866]

@@silicon212 I'd put money on the railroad "saving" money by not maintaining the engine air filters.

[@silicon212]

@@pootispiker2866 that seems very likely.

[@pootispiker2866]

@@silicon212 This also happens if the exhaust screen is plugged up

[@ralfie8801]

It also can happen when you take the engine up too quick before it’s warmed up. The governor hunts and the turbo burps because the engine is too cold to be revved that high yet.

[@PaulNoake]

Nothing finer than working at a locomotive Depot and hearing the siren song of an 16-645E3B powering up

[@d2sfavs]

so cool you got this load test on video.i love it when it burps near throttle #8 maybe thats why the engine was set out you dont see this kind of stuff anymore.

[@LocosPorLosTrenes]

the best sound you can have a diésel engine EMD 16-645 is perfect

[@BritishRail60062]

Music to my ears! Shame that the UK HST's weren't repowered with the EMD645E3 units instead of those MTU units. These EMD locomotives sound like a beast! ;).

[@dylanruppert4547]

***** trust me you have no idea lol its amazing hearing them go by my house lol

[@HotForgeChaos]

We got the E3C's in our DFT class diesels here in NZ. Damn they sound sweet

[@BritishRail60062]

I totally agree with that statement folks :).

[@zodiotekgaming]

Well those American engines are a bit heavy, which wouldn't really do the BR Class 43 any good

[@TestECull]

They last forever, make plenty of power, are exceptionally reliable, and don't require all that much upkeep. I'm pretty sure that earns them the right to carry a bit of heft. Besides, that weight just means more tractive effort.

[@955redavenger]

Look at those fumes. well, we all know that the engine is cold and it's suppose to do that. great vid

[@williammadona7668]

Parabéns pelo vídeo, adoro esse som, tanto que o estou utilizando no meu Train Simulator, perfeito.

[@BenjaminEsposti]

Seems like a somewhat unhappy engine! The "barking" noise is from the turbocharger clutch, it is worn out/failing. I'm guessing the black smoke is caused by the turbocharger not running at the proper speed, hence starving the engine of air slightly.

[@silicon212]

It's probably surge due to a plugged air filter.

[@jimolsen8632]

You're right; it's pretty hard to tell by just watching a Video and listening as the Engine is Notched Up. First thing I would do would be to check the Turbo Screen to see if it is plugged. When the Engine goes to Notch 8 and drops off the Clutch, if the Turbo Screen is plugged it can Burp like that. If you rev the Engine up using the Lay shaft, you can carefully get into the RPM range where the Clutch comes in and out and a Clutch failure is proven. Good catch, the Locomotive Tech probably caught it too and called it in so it can swapped out and come to the Shop.

[@amessman]

Last comment was 2 years ago but whatever, Jim kinda explained it, I've heard the turbos are clutch driven till notch 5-6, then they run like a normal turbo, sometimes the clutch gets stuck where it doesn't disengage properly, causing that smoking, as the turbo can't spin up to the proper speed, can't deliver enough air, and the engine runs rich.

[@fireshorts5789]

@@amessman just wanna say its nice to see comments from people who actually know how these engines work (and clearly have experience working on them) versus the usual train fans and their commentary. Thanks for that, even if it was a 2 year bump.

[@jessesager9460]

This sounds awesome on a home theater system.

[@1918dawson]

The last minute or so is the best 👌👌

[@Dragunov1Bros]

Sounds/looks like it needs a rebuilt turbo clutch, it's making it bark (Like at 2:42).

[@rogertycholiz2218]

Bark or no bark still music to my ears!

[@tylersteffen200]

The Barking is more likely caused by a cylinder not hitting the way it should (misfire). When Diesels are cold its very hard for them to combust sometimes, when you hear the bark you see black smoke come out of the stack, Thats unburnt fuel going through the exhaust side of the turbo and exiting the exhaust stack.

[@silicon212]

@@tylersteffen200 Unburnt diesel is a whitish-gray color. That's what you see when a cold diesel is started up - the cloud, or 'clag' as referred to on the other side of the pond, is pure unburnt diesel. The black is diesel that is improperly combusted, usually due to a fuel rich condition where not enough oxygen for the burn is available, resulting in the formation of carbon soot. The turbo can surge if it has an issue with a bearing, or it can surge if it doesn't have enough intake air on the impeller side. Either cause results in the same outcome - the surge, or bark followed by black smoke due to a momentary fuel rich condition.

[@tylersteffen200]

@@silicon212 could also be the turbine of the exhaust side of the turbo could be havely worn. Aswell as bad bearings as you've said

[@Clear333track1west]

The same EMD 16-(cylinder) 645-E3 is standard on an SD40-2.

[@TheNWClassA1218]

I caught that same loco as 2nd unit on a trash train!

[@irasthewarrior]

5:01 Where is that high pitch sound coming from ?

[@silicon212]

that is the clutch coupled turbocharger on the EMD 645 engine. You hear it at low RPM at a sustained note for a given RPM, because it's a two stroke diesel engine and needs to have charged air to run. At speeds below the 6th power setting (notch), exhaust gas velocity and heat alone is not sufficient to run the turbo, so the compressor/impeller is run off of the camshafts, at an increased speed through gearing, via an overrun clutch. When the exhaust pressure is high enough to run the turbo, the impeller decouples and runs off of the turbine in the exhaust as a true turbocharger.

[@irasthewarrior]

Do you enthusiasts like the EMDs better than the GEs? I'm learning about the refurbishing of the EMD rolling stock on the Virginia Ave tunnel job in DC watching the freights roll by and I got a chance to chat with a CSX VP before I got yelled at to get back to digging

Daniel K.... what you heard is either the possible result of a plugged air inlet screen, or... the turbo dropping off the clutch and needs replacing (the turbo clutch). In regards to your question... "Had she sat for a while?".... it was shut down over-night.

The SD40-2 uses a turbocharged EMD 16-645E3 engine, or prime mover.
