Loco 66542 cold start attempt 3...

[sandraealex]

best sound

[jaggass]

wheres the body gone? They dont rev high dont need to all the torque from like 600rpm.

[jnewbon00]

hahaha i could actually see the carbon foot print AWSOME

[GordonFreemanD40]

whoa up close it sounds like a DD50...

[aussietraindriver]

hahahaha ALCO start with an EMD!!

[GordonFreemanD40]

@aussietraindriver not much...

[Johnny64ism]

@ Jim40135 that yinging sound is the gear drivin  turbo charger it runs off the crankshaft till about 500 RPM then the clutch kicks off and lets the exhaust take over driving the turbo

[22fret]

three zillion hp @ 37rpm...:D

[midlantic1]

How many GMP does this burn?

[ttrainmixx]

Nice !

[AccAkut1987]

sounds like a Star Wars pod racers round the 0:18 minute mark

[Blackphoenix0704]

was at 1:39 the airfilter?

[gobigblue911]

I was wondering an emd is a 2 stroke... how would it run with out the turbo hooked up? doesnt it require forced air to scavenge the burnt fuel out of the cylenders? is the turbo on some kind of centrifical clutch for low rpms or something...

[silicon212]

@gobigblue911 The turbo is geared to the crankshaft through an overrun clutch. It's geared to run at something like 12x crankshaft rotation.  This allows the engine to run at speeds of less than run 6, where exhaust gas pressure is insufficient to directly drive the turbo.

[251CE]

I'm an ALCo fan at heart, but I've got to admit that sounds seriously beaut! Any chance they could run that as is through Maryland East London at about 1 in the morning for my benefit...?

[skeezix91]

Almost sounds like an alco when it's throttled up.....weird.

[raymondrayban]

oh i do love the sound of aclass 66! ,...........i love that ying ying sound as it ticks over it comes in at,0"16 ying ying! ying ying ying ying ying ying ying ying,ying ying ying ying yingyingyingyingyingying , ying ying ying ying + so on !

[DARKJURNEY]

my favorite sounding engine ,no contest

[75Bird455]

That is awesome!



[pyronathanpyro]

tbh its a silenced v12 if im right well silenced when teh manifold and that are on nice things thow are sheds :)

[Porrly]

Sounds just like a dirty diesel. Chug chug chug.

[roadwolf2]

give her individual pipes for each cylinder

[BNSF5608]

It wouldnt run after about 470 RPM however, That turbochargers clutch would disengage and the engine would choke to death with no exhaust pressure pushing that turbocharger.

[silicon212]

@BNSF5608 It would run fine. The turbo clutch does not 'cut out' at a certain speed - the exhaust becomes strong enough to drive it beyond the geared speed. If there is no exhaust gas present (as in this clip), it will still run, even to run 8. It just won't make the power it should. It would more or less produce the power of a Roots-blown equivalent.

That's often how the railroad will convert a GP40-2 into a GP38-2 - by pinning the overrun clutch.

[Ruba81]

Моща!!

[Starfleet0]

can someone tell me the displacement of this engine? also how do i become a locomotive mechanic?

[Learnin2Fly08]

@Starfleet0 12 cylinders 710 cubic inch each

[Starfleet0]

i feel naughty having seen this, like its too awesome for human eyes.

[madmax200769]

Sounds a damn sight better without the stupid silencers

[nov3019892008]

Why don't cars sound like this? lol

[dempsey088]

Just like when preservationists get their hands on a class 60, the mufflers will be right off! Hellfire.

[GingerPhilG]

I was going to get some jump leads and my car booster pack, but I think you got it sorted now... lol...

lovely sound there..

[50046ajax]

This sounds realy nice with no silencer almost a class 37 or Ruston sound to the power unit thanks for posting

[adamswindells1]

I love as all the carbon comes flying out of the exhausts when she fies up :P

[drummerliam]

When starting do these engine's require another means of providing the charge/scavenging air. Say like an electrically driven blower or similar?I know the turbo charger is gear driven up to a certain rev range, so obviously no problem at low RPM once the engine is running. I can sometimes hear what to me sounds like a compressor just before the warning buzzer, would just like somebody to clarify that for me. Im fascinated by these engines and would love to know a little more about them.

[gmsd70mac]

sweeeeeetttttt!!!!!!!!!!!!!!

[NovioSites]

This is just great!

[namco21gamefreak]

EMD know how to make the best sounding engines

[lorirocks777]

Where's this?

[willispwool]

is it a ge

[buckshottfonk]

My god, what a great sounding engine, it doesn't sound like a 2 stroke, not much smoke either. Thanks very much for posting, great vid.

[rhondaw1]

...........love it............

[trainfanNL]

Is this a new locomotive engine received or is the engine look like? He worked here half open and there is a crane.

[DG19075]

Love that EMD sound!

[PauliosVids]

Brilliant

[normken]

The most beautiful sound in the world. Thanks!!

[kratos32godofwar]

and did u notice something fell in to the exhaust from the conection to silencer

[kratos32godofwar]

sounds nearlly like a 37

[okotokspaul]

my lordz wot a great sound

[jim40135]

But *something* is still making that annoying yinging noise. What is it?

[formidable38]

@jim40135 Mechanicly, gear driven turbo. Gear driven turbo= zero turbo lag as it behaves like a supercharger.

[hobbified]

@formidable38 if it's not exhaust-driven, it's not a turbo ;)

[formidable38]

@hobbified It is because it becomes exhaust driven after 500 rpm by means of an overrun / dog clutch.

[hobbified]

@formidable38 funky, but okay. Thanks for the info :)

[kleetus92]

@formidable38 And once it gets enough engine speed the overrunning clutch lets the exhaust take over and build full boost.

[formidable38]

@kleetus92 Yeah, you got it. All the 66's use the newer 710. Class 57 uses V12 645 and the 59 uses V16 645- the best of the lot!

[formidable38]

@jim40135 In addition, thats why you still hear it even though theres no exhaust manifolds connected becuase its mechanicly driven and not exhaust driven. This system is the EMD's strong point. No lag means spontanious power and low exhaust emisions in the from of no black smoke on throttle-up thats normaly caused by turbo lag / slow spool up of the turbo.

[jim40135]

@formidable38 Thanks for the info.

[goinghomesomeday1]

Did I detect a sticking exhaust valve in cyl #1 as you look at the video (right hand cylinder).

[pinza55007]

awsome. love this vid.

[Semifastslim]

Ohh Matron ! That does sound much better ! I`ll have one !

[GRIDMASTER6]

Interesting video,but sounds crap heard better with exhaust manifolds removed.Try a class 56!!.

[jim40135]

@GRIDMASTER6 Post some footage then chief!!

[trainlover658]

she's purring now

[Xantec]

whats the litreage of that puppy?

[formidable38]

@Xantec As its American it uses cubic inches. This is the "710". All EMD engines use those numbers to denote cubic inch per cylinder, eg, 567, 645 etc so this one is 710 cubic inch per cylinder which converted to metric is 11.634 litres per cylinder. X that by 12 eqauls 139. 6 litre. The V16 version of this is realy serious, 186 LITRE!

There is also a V20 710.

[Xantec]

@formidable38

thanks

I was expecting a big engine, just not quite that big.

[EWS60500]

What a beat, I have never heared a EMD engine sound so cool, I mean that was imence, got a vid of a class 60 starting like that?

Cool stuff mate

[kettle750]

Cold start after removal of exhaust manifold for gasket replacement.Thought it a good idea to flash it up and clear any debris from the ports.

[tpvalley]

@kettle750

so how was the blower driven here?

they run off exhaust gasses apart from at start up where they are mechanically driven dont they?

[monkehbitch]

@kettle750 Clear the ports out?you just wanted to be an antisocial bastard, more please! I love the sound of an unsilenced diesel!

[tpvalley]

@kettle750

so turbo is mechanically driven during start up?

[papabugs71]

@tpvalley Yes, the turbo runs off the crank up to +/- 500 RPM depending on load. After that the overunning clutch kicks out & the turbo runs off exhaust gasses. :)

[tpvalley]

@papabugs71

so if u revved it like this above that speed it would make tons of smoke and the rpm would drop to 500rpm?

[Rickstew86]

If only Class 66's sounded like this in daily service, it'd be far more interesting! Nice video. Great to hear the 66 engine unsilenced.

[panther590]

im supprised at the rough start 0:10 is this becouse these silancer has been removed? and sounds a bit rough why is this

[formidable38]

@panther590 well, after my 20 odd years of messing with stuff like this i would say she's just cold and maybe the fuel system has been disturbed. considering its cold it runs as sweet as a nut and very smooth. You need to see an EE power unit when cold, thats what you call 'sounding rough'!

[formidable38]

A 710 with no manifolds on, f****in awsome! Imagine the racket from that bastard under load........

EMD primemovers are the bomb proof daddys, end of!

[kleetus92]

@formidable38 That's a 710? Thought it was a 645? Either way... I could see it with 16 chrome pipes sticking up through the body!
