The noisy bit

[@Rocketboy1950]

We all suffered from industrial deafness in the early days. Management had to be dragged kicking and screaming to soundproof those cabs but we forced the issue. I can still remember when the brake valves exhausted in to the cab.That was the most ear piercing noise you can imagine.

[@nikosjk1]

Fantastic video! I love the sound of turbocharged EMD's. I wouldve loved to hear it go all the way up to run 8 from inside the engine room but i guess you would have probably gone deaf then!

[@dontstealmacosx]

The standard air compressor is a three-cylinder Gardner-Denver unit. There have been alternates in the past, however. If the unit has the G-D logo, then it is a Gardner-Denver.

[@timberhustler]

they are driven by engine crank via spring loaded turbo drive gear until it reaches proper RPM and exhaust pressure. Then it is driven only by exhaust pressure. It is really a turbo and supercharger in one. They really are a cool engine.

[@produKtNZ]

Last time I read any stats about these Turbo's: They are mechanically assisted, so they create boost from the get go via a shaft & gear system from the crank, and flow around 800P.S.I and then some.

[@bricub72]

It's the lay shaft, the lever you see them pushing, that controls the fuel flow

[@Rocketboy1950]

Been there, done that. In the good old days we used to just wander through. The only thing that concerned me was a crank case explosion or a rod coming through the side. And yes I have significant hearing loss as a result.

[@proprietary1]

you are right gear driven to 80 percent then a sprag clutch disengages therefore making it a true turbo I worked as a mechanic rebuilding these monsters 645's, 710's 28000 rpm, weight over 3000 pounds, the turbine and compressor wheel alone weigh 125lbs awesome turbos

[@produKtNZ]

Cheers for that =). It's always good when people get together and combine their knowledge about such things =)

[@dontstealmacosx]

Technically, it is not un-silenced. There are no silencers on these engines. What has been removed is all the piping between the engine block's exhaust ports (which are water-cooled) and the input to the turbocharger. The output of the turbo is, of course, the exhaust stack. So, the turbo's turbine input is horizontal, whereas the turbo's turbine output is vertical.

[@thisisbloody]

@gm16v149 You're correct, the UK 66's are 12 cylinder, the EMD 16 cylinder engine in the video is the same as the UK 59's.

[@dontstealmacosx]

EMD 567, 645 and 710 are constructed identically. The basic design of ca. 1936 was so fundamentally sound, from an engineering perspective, that it could be very easily "scaled". Because certain dimensions remained the same between the 567 and the 645, 645 service parts may be employed on 567s The 710 changed many of those critical dimensions. Should, say, an 800 be forthcoming, I would assume that new design would retain as many 710 dimensions as possible.

[@kdlehel]

the emd engine is an art in railtraction.

[@KSE828]

wow they must have some serious sound deadening material in the cab. It's so quiet compared to the engine room directly behind.

[@rich200tdi]

Nice clear video mate! Sounds quite alot like our GM built Class 66 here in the UK. If only Vauxhall vans sounded like those engines too!

[@Rocketboy1950]

Hooray for creep cranking, saves running around cracking them all open pre start up. I must admit to a strong liking for the old ALCO's but it's hard to beat the sound of EMD's.

[@Rocketboy1950]

No Valentas down under as far as I know. We have the XPT's in NSW which came with them but I think ( could be wrong ) that they have been re engined with something else.

[@Rocketboy1950]

No Brian it is as I had already answered. That is by placing the reverser in to direction.

[@Rocketboy1950]

The overspeed trip would have saved the day if I had been silly enough to lean on the layshaft

[@DounutCereal]

@Rocketboy1950 Thanks. They sound pretty good on the inside too!

[@Rocketboy1950]

@mckerraljamie Took me all of 5 seconds but YT will not allow a link in this box so just search EMD 567 engine and you will find one. The bigger engines are basically the same but......bigger as in 654 or 710 cubic inches per cylinder

[@Rocketboy1950]

@ZetanCrisp Pretty much like an SD40 or one of our old Victorian GT26C C class units.

[@bnkwupt]

Nice video. The turbocharger is massive and sounds great! Please post more videos with the engine under load if you can. :)

[@SyrusWolfe]

how amazing that sound!

[@Rocketboy1950]

It should sound like a 66, the 66 is based on that unit albeit minus a dynamic brake I believe.

[@megs905]

thanks for video that is really cool I enjoyed it thanks for the tour of the EMD!

[@gm16v149]

I'm pretty sure that's a 16 cylinder you got there (bit hard counting the cylinder covers), I know the UK 66s are 12 cylinder, 710 series engines (710 cubic inch per cylinder). I believe the 16/645s are about the same HP (around 3300) as the 12/710s which are later technology with electronic fuel injection etc. The new SD 70s they've just bought in the Pilbara are 16/710 series EMDs, about 4500 HP a guy that drives one told me. I'm no expert, so correct me if I'm wrong.

[@MichaelSullivanPhoto1985]

North America, Europe, Australia, anywhere. The EMD 645 always sounds best.

[@jerry91a]

damn, that alternator is huge!!!

[@choirboyfromhell1]

0:48, those are actually drain cocks to insure there's no water in the cylinder before starting. Yes, EMD's sound constantly boringly nice, but I'll take an Alco or BR Class 50 anyday.

[@railbum]

love that whistle baby!

[@dontstealmacosx]

A 16 cylinder engine weighs approximately 38,000 pounds. The corresponding alternator weighs approximately 19,000 pounds

[@formidable38]

LOL what a great answer! :) You do get 'em on here dont you!

[@Rocketboy1950]

That may well look like a QR sticker but I can assure you it was a PN loco on Victorian broad gauge.

[@np560]

Excellent sounds. I love it when you touch the layshaft and she revs a bit. Here in the states we gotta open a whole lotta doors to see all this good detail. Your recorder apparently has an excellent sound system! What brand & model is it?

[@Rocketboy1950]

I imagine you mean the three cylinder one which is the air compressor.

[@Rocketboy1950]

Put the reverser from centre in to direction.

[@ZetanCrisp]

Search for this video on youtube: Loco 66542 cold start attempt 3 It has the silencer removed!!! Always wanted to know what they sounded like unsilenced :)

[@Rocketboy1950]

In response to comments re not being able to hear me and as a result of the new service available I have added annotations.

[@MrGrumpygit488]

The class 57`s(ex class 47)have this power unit, why they changed the Sulzer for one of these i`ll never know.

[@FFCCDirecto]

It sounds similar a spanish 333.incredible!!

[@roadwolf2]

good old vline g class nothing beats em

[@mckerraljamie]

@NewJerseyBill... Hey thanks for the reply, I think it's a fascinating piece of engineering. Even tho I understand engines these beasts have made me realise how little I really understood, fascinating. I'd love to see a diagram of the internals, anybody know of some diagrams on the interweb...?

[@Rocketboy1950]

@bolts1111 I don't know why the sticker is there. It was a PN loco........maybe somebody being or attempting to be funny.

[@Rhys9586]

g class? it had a fairly sharp exhaust note but a N/G cab. 2 locos wich have a smooth note

[@Rocketboy1950]

And just where do you think the design of the 66 came from ? :-) This one's better, it has a dynamic brake.

[@Rocketboy1950]

OK so now I have done that and it has gone very quiet in here. Now what do I do.

[@PaulNoake]

Purrrring like a kitten

[@clagfest]

Is this a G Class? Had a drive of one of those. Ace piece of kit

[@bolts1111]

I thought the air compressor would be a shite load bigger than that. Why is there a Qld Rail sticker on the wall?

[@Rocketboy1950]

you need to find a way to add subtitles or something so we can hear you a bit better You're right, I do. This is all pretty new to me, still got learner plates on.

[@mckerraljamie]

Question for you? Is the low drone Whoop Whoop Whoop the noise from the turbo gearing that is on EMD engines to combat turbo lag? Or is it the shaft running between the crank and the generator, nobody seems to know..........?

[@keithode1737]

I'd grab the lay shaft and give it a good yank.

[@MrRandom750]

hey whats that littel engine at the end of the large one? very awsome video

[@dewmellon]

I have been in there @ notch 8.

[@Rocketboy1950]

Question; how do you go from low idle to high idle. Answer ; move reverser from centre to direction. I can't make it any easier to understand.

[@jasoncaves7092]

with these high turbo engs they can idle at 180 -190 rpm in super slow idle ... ad 70s used to be on fec railway ,,,also 430 -434 mid 80s era did . Woodward gov. chip to save fuel

[@Thetrucky69]

THIS ENGINE SOUNDS FUCKEN TUFF !

[@silicon212]

Looked and sounded more like a 710 than a 645.

[@bolts1111]

@dodgeramb59 Are you for real? Thats a bit over a tonne! It only looks to be the size of a carton of beer?

[@enginemasterbuilder]

ruston v16 and that engine sound alot alike

[@Rocketboy1950]

That was in a G class

[@tiptopsound]

badass!

[@Rocketboy1950]

@mckerraljamie You can include me in the nobody seems to know section.

[@Rocketboy1950]

@DounutCereal G class

[@redbullracingktm]

how big is the turbo in that train?? u had zoomed in to far to see the hole thing. plz reply about info ion the turbo. :)

[@aroncbds]

Diesel forever!!!!

[@SemnalMec]

Imi cer scuze pt confuzia din measjul precedent! Eu sunt mai mult cu partea de infra "specializat"..scuze..credeam ca-i vorba de alta locomotiva

[@Rocketboy1950]

yep

[@ac83052]

So if it's in neutral it will high idle but if it's forward it will low idle? I drove a GP40-2 and that did not happen

[@SemnalMec]

Urat zgomot.Locmotivele astea de tranzitie nu vor reusi sa egaleze prestigiul si frumusetea clasicului Sulzer de pe 60-62-uri

[@Rocketboy1950]

Define "how big". In terms of physical size/dimensions/boost. Maybe somebody can give you an accurate answer. I just drive the things.

[@ac83052]

How do you move the engine from low idle to high idle? I know it's not the throttle...

[@class313]

so its the turbo that makes EMDs YING?

[@bennyboyracing2974]

What class loco was it?

[@Landaux]

Be in there @ notch 8 under a full load, and see how deaf you get. :-)

[@rhondaw1]

thanks... interesting.

[@formidable38]

Ive done it and made a video of it. Couldnt stand it without ear protection though Lol! Its prety f*****g loud !

[@DounutCereal]

What class is that?

[@roadwolf2]

what class of loco is that rocketboy

[@Raune88]

Try pulling the lay shaft very hard:D

[@31144]

This engine sounds just just like our 66's (british loco) not a sound I love to be honest,take the silencer off and it may sound ok

[@jamez920]

sounds kinda like a class 66...

[@Rocketboy1950]

So have I. We're both idiots.

[@Rocketboy1950]

NO !

[@Rocketboy1950]

Nope, PN but absolutely no difference.

[@adam1234a]

ha ha ha

[@Rocketboy1950]

absolutely not, spend enough time on real ones
