- Listen as 3000 horses come to life! This is a 1972 EMD SD40-2 coming to life! enjoy the sounds! here are some specs on the engine
16 cylinder two-stroke 45 degree V-engines. Each cylinder is of 645 cubic inches (10.57 liters) displacement, hence the name; with a bore of nine and one-sixteenth inches (230.2 mm), a stroke of ten inches (254 mm) and a compression ratio of 14.5:1. This engine features a turbocharger.

I agree SD40-2's were bulletproof. I worked as a train dispatcher for L&N/CSX for a number
of years and they were always my favorite locomotives. They very seldom had problems
and would not quit. They could get a tonnage coal train over the road better than any other locomotive. One of my favorite quotes is "give me a good engineer and 4 SD40-2's
and we will move some freight".
I work for a Class 1, and Dash 8s are about the worst GEs you can possibly get. I'll gladly take an SD40-2... those things pull well and are built to last!
SD40 is my favorite sound engine. The pitch of the turbos just is awesome.
sd40-2 's are bulletproof, they almost never have any problems.
THIS IS THE TUFFEST ENGINE THAT I HAVE EVER HEARD. THIS SOUNDS TUFF.
Very cool, the SD40-2 is one of the best sounding locomotives from EMD. Thanks for sharing!
Love the sounds of the engine idling! Best locomotive ever!
Nice shot of the layshaft lever. I ran a EMD NW2 with a 12V567A in it. The layshaft was going the opposite way. You had to pull the layshaft towards you to open up the fuel rack until it started. Then hold the layshaft 1/2 way until the oil pressure was high enough to keep the govenor (over speed relay) from over reving the engine. After about 2 minutes you could let go. But until that time, you could feel the governor trying to open the throttle.(Continued)
Well if you've ever wanted to know how to wake up 3000 horses at one time, this how. Much easier than I ever would have thought that's for sure! AWESOME SOUND HENCE AN AWESOME VID!!!!!
I'm in love again, there's something about the idle note of an early EMD that's just 'right' can't explain it, it just sounds like it's meant to be.
I love the sound and the sheer power of these things
Those SD-40-2's were the greatest. Theyre like a 73 Chevy Impala 350!!!!
nice job the sound of those 645 engines comin to life is awesome
thanks for uploading this i love the sound of any classic EMD
You should always run the layshaft through full travel once primed to ensure no sticking racks - helps avoid the excitement of an overspeed.
Dear lord thats a nice sounding primemover.
Really nice Sound of a big engine!
Some governors (as in this example) are marked Sardello Inc, but these are designed the same as a Woodward governor.
It is apparently standard practice to crank until combustion is achieved and the governor revs the engine slightly. Thereafter, the engineer/driver may use the "layshaft" to manually rev the engine, usually twice.
However, the governor (a complicated analog computer) has already confirmed proper operation of the engine, and this manual revving is not actually necessary.
AH I LOVE THE SOUND OF A TRAIN STARTUP IN THE MORNING!
Sounds awesome, gotta love the SD40-2's
@tigermki No. That was the "Layshaft Lever". It is a "hand throttle" used in starting up a diesel locomotive engine. Diesel don't have a carburator, distributor, spark plugs or ignition wire. The heat of the compression stroke heats the air so hot that the diesel fuel ignites on it's own. Diesel can use, jet A fuel, kerosine, home heating oil#2, corn oil, vegitable or even crude oil IF you heat it enough. Diesels don't have an octane rating, they have a Cetane rating=how slow the fuel burns.
@silicon212 You are correct there, I can't think of another engine more reliable or longer lasting than EMD's 645s when you're talking around 3000 HP.
Sounds great for me for the EMD motor sounds
I love the sound
@2008FORDF450V8 EMD still makes 2 stroke diesels. GE makes the 4 strokers.
And the C40-8C and AC4400CW! I LOVE EMD and GE locomotives equally!
@strobx1 We had to go to the electrical cabinet in the cab where we pulled out the PC, Battery Field & fuel pump slide switches. The starter button was there also & when it was pushed there was a loud pop with sparks. We turned the fuel pump on first, then I'd walk on the left side cat walk open the door & see that both the fuel pressure & return line fuel pressure was 15PSI for both guages. Then I'd tell the engineer to push the starter button while I worked the layshaft. You have it easy.
WOW! Beautiful sound.
Very nice! Thanks for posting!
When this engine was built EMD stood for Electro-Motive Division of General Motors.
EVERYTHING ABOUT THIS IS TUFF.
Only on marine and stationary engines.
Locomotives always use dual electric starters. Generator field on early models. I believe this has to do with the fuel system "priming" function, where the fuel itself is utilized for Unit injector lubrication and cooling, and this subsystem is a prerequisite to starting.
The SD40-2 is the standard by which all others are measured.
Many have been rebuilt several times, and are still in operation.
The same cannot be said for GE's pre-Dash-9 locomotives.
@strobx1 i figured that out in one of his other videos and i wasnt asking what the engine ran on but thx for that i always figured it was diesel fuel only
WOW...nice sound...
GREAT SOUND! I love this.
usually an idea to push the layshaft in to assist starting.. rather than allow the starter motors to keep turning until the engine fires.
Wow this thing sounds very reliable do they have starting problems sometimes
wow amazing startup man
It's a common Misconception that a Transmission comes of fo the Engine that goes to the trucks. The Engine actually drives a Generator that drives the Electric Motor going to the Trucks.
OMFG!!! Yess!! I love that high pitched whine!
These EMD vs. GE wars HAVE to stop. I'm a EMD guy, but I'll take a GE any day. Especially a Dash 8.
EMD especially when it was the Electro Motive Division of General Motors sounds way better than even the old GE Uboats
not to mention it also sounds almost like a dash-7 too!
@doctorfeelucky It lets them carry over dimensional loads, like say pre cast concrete slabs for building factory walls or machinery items tilted on the edge and still stay inside the allowable train 'profile'. Anything that protrudes outside the profile could, and in Australia would for sure, hit bridge structures, platforms, or passing trains.
love the SD40's good motor!
Like the sound of a sweet muse
You should pushed that PG regulator handle a bit more! Awesome, the mighty, reliable and powerful SD40-2, the most popular and numerous Diesel locomotive of all times! Same with the EMD GT26CW-2, which is an EMD export locomotive for Europe (it has the same frame like SD40 and the engine, generator and D77 traction motors, except the body is different), just love it, hauls freight with no problem, but from 14 engines we had only 1 is left in operating condition.
Nadajmo se da ce NRE i preuredit 001 pa da i treca bude...
Music to my ears!
THIS IS THE BEST VIDEO EVER THIS ENGINE IS SCARY, IT SOUNDS FUCKEN TUFF !
This is in the engine room of the locomotive. This is turning on the main diesel engine..
do they make 2 stroke diesel engines anymore or could u tell me why they dont use 4 stroke diesels in locomotives please thanks
I just love that Diesel engine
I LOVE THIS SOUND!!!
On this engine is compressed air used for starting or is the generator connected as a motor to start it ?
I'm sure glad their lasting!
I always thought some EMDs did use air starting. If the air start air tank is completely independant from the main air supply it will hold air for weeks. From my own experience air starters are a lot more reliable than electric starters as long as you perform basic maintenance,
Sorta off topic, but I was wondering, what are those train cars that have nothing but a wall in the center and what is the purpose of that? Can anyone tell me?
is this a Norfolk Southern sd40-2
how many cars can one SD40-2 locomotive pull?
That sounds nice.
@skyav8r These load up a HELL of alot quicker than the GE does.. awesome for working a local.
LISTEN TO THAT BOOM BOOM BOOM BOOM NOISE AS IT'S TURNING OVER AND THE TURBO GOING OFF IT'S FUCKEN NUT THIS ENGINE IS FUCKEN TUFF !
Where is that apu unit that was mentioned on that caution tag?
can SD-40's work in dpu? or do they work as a MU setup?
What is the high pitch whining sound later EMDs there make? Turbo Charger?
Yep, turbocharger!
+Patriot1776 need that turbo on my diesel
Good stuff. None of that other crap.
THIS ENGINE SOUNDS FUCKEN TUFF ! THIS IS THE TUFFEST ENGINE IN THE WORLD !
its a 150 litre diesel engine?
I have the same horns that this train came with they came off of a Union Pacific sd40-2 that was scrapped
Who reved the engine at start up around 57 sec i know u did later
not a problem starting
was that the inside of the train?
i should use this for my computer start-up noise
Dual electric starters, of the very same type which Charles F. "Boss" Kettering invented while he was a founding partner of DELCO, later absorbed into GM.
Stationary engines usually have air starters in the very same position as the locomotive's electric starters,
Air starting is not used on locomotives as the Gardner-Denver or WABCo air compressor is mechanically driven from the engine, and one cannot depend upon the availability of air for starting.
Very much a chicken-before-the-egg issue.
wow love me some sd40-2
Could you video an F40PH starting up?
So that's how it's done. I wondered how locomotive engines were turned on and off.
what was that lever for choke
Eu amo SD40!
@RayVal53 Not to mention that many people do not know that it is actually electric motors that provide all the torque to the wheels. If I was a betting man I could take a 5 HP motor and win bets all day against a 15 HP gas engine in a stall shaft duel off; just because of the massive torque of the electric and the fact that the majority of the population is so ignorant of the electric motor's abilities so many people would bet money that the gas engine would win. LOL
freakin' badass
What are you doing under my truck hood.
Anybody know if any ho scale dcc decoders have a startup sequence for the SD40-2? BTW awesome video and that is a totally awesome sound in my opinion lol 3,000 horses waking up
Austin Brodzinski gotta make it yourself saddly
Really? I'm surprised Loksound hasn't done that yet.
I have an inter mountain with lok sound. It has the starter but that’s all. I’m good with that though because I don’t want to wait that long before I go.
never seen a mechanical start EMD before, the Marine ones I work with are all air start.
A lot of the good old EMD's are similar to this. flip a few switches in the cab, loosen all the relief valves, turn her over a few seconds without fuel to make sure no water is in the cylinders, close the valves, prime her, and crank her up.
Some Sd70's are air start (I think they are called SD70AC, but the air tanks easily lose pressure when the engine is off. The starter is off of the same tank as the brake's are. In event of pressure loss, another locomotive with the engine running can be connected to the consist hose and the six hose's located on the plow on either end of the loco, then after the pressure is built back up, the loco can be started and the hoses are disconnected.
@2008FORDF450V8 Umm, no. Sorry, the EMD two stroke 16-645E3 (what this locomotive has) is one of the most reliable diesel engines ever designed.
@mt90945557 hey, the GE C44-9CW sounds pretty damn good.
@Train2590 Yes! And with pride too!
whats the screaming is that the gearbox?
Locomotives do not have a gearbox
i sound like an idiot but what does emd stand for
he just want to hear it roar
@tigermki nevermind i found out great video
you should put a cummins QSK60 V-16 engine would be a lot more reliable trust me
@Train2590 I did, now. But I like a B40-8 start better.
intresting
it is giggling like it is being tickled
And I thought that even start up was done from the comfort of the cab.
OMG IT IS
@jaggass turbo unit most likely
@jaggass Locomotives DO NOT have a gearbox!
Sounds way better than GE junk!!!!!!!!!!!!!!
