Starting a Locomotive Engine : EMD SD40-2 engine Start up

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".

[@stumper661]

SD40 is my favorite sound engine. The pitch of the turbos just is awesome.

[@NS6677]

Love the sounds of the engine idling! Best locomotive ever!

[@TrainTrackTrav]

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!!!!!

[@BNforever2009]

Those SD-40-2's were the greatest. Theyre like a 73 Chevy Impala 350!!!!

[@Canesfan7012]

thanks for uploading this i love the sound of any classic EMD

[@TheGingerBuff]

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!

[@skyav8r]

@2008FORDF450V8 EMD still makes 2 stroke diesels. GE makes the 4 strokers.

[@RRYankfan]

not to mention it also sounds almost like a dash-7 too!

[@admydragon]

Dear lord thats a nice sounding primemover.

[@strobx1]

@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.

[@strobx1]

@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.

[@Tzed250]

When this engine was built EMD stood for Electro-Motive Division of General Motors.

[@BR218fan]

Really nice Sound of a big engine!

[@bnsfjay]

Sounds awesome, gotta love the SD40-2's

[@Cnw8701]

And the C40-8C and AC4400CW! I LOVE EMD and GE locomotives equally!

[@thesportbikeman]

EMD especially when it was the Electro Motive Division of General Motors sounds way better than even the old GE Uboats

[@bait28]

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.

[@ThePainTrain765]

GREAT SOUND! I love this.

[@whorayful]

@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.

[@fixierider97]

wow amazing startup man

[@kyletheangrygamer9148]

AH I LOVE THE SOUND OF A TRAIN STARTUP IN THE MORNING!

[@thespwillliveforever]

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.

[@radar15627]

love the SD40's good motor!

[@shadowknight227]

i should use this for my computer start-up noise

[@Silentroller93]

I have the same horns that this train came with they came off of a Union Pacific sd40-2 that was scrapped

[@silicon212]

Very nice! Thanks for posting!

[@MultiBrainsmart]

I love the sound

[@Thetrucky69]

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 !

[@Triplex5014]

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.

[@railfancroatia1141]

Nadajmo se da ce NRE i preuredit 001 pa da i treca bude...

[@Dansvideos03]

I just love that Diesel engine

[@Mike_Turcott]

That sounds nice.

[@Thetrucky69]

THIS IS THE BEST VIDEO EVER THIS ENGINE IS SCARY, IT SOUNDS FUCKEN TUFF !

[@TrainCamera]

@skyav8r These load up a HELL of alot quicker than the GE does.. awesome for working a local.

[@flyingscrapyard]

Good stuff. None of that other crap.

[@dougd120]

not a problem starting

[@adamchoruzek5726]

I LOVE THIS SOUND!!!

[@bait28]

@mt90945557 hey, the GE C44-9CW sounds pretty damn good.

[@SOU6900]

Where is that apu unit that was mentioned on that caution tag?

[@dontstealmacosx]

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.

[@2008FORDF450V8]

do they make 2 stroke diesel engines anymore or could u tell me why they dont use 4 stroke diesels in locomotives please thanks

[@NS9045]

is this a Norfolk Southern sd40-2

[@Pilotguy251HC]

Wow this thing sounds very reliable do they have starting problems sometimes

[@Thetrucky69]

THIS ENGINE SOUNDS FUCKEN TUFF ! THIS IS THE TUFFEST ENGINE IN THE WORLD !

[@P51ride]

On this engine is compressed air used for starting or is the generator connected as a motor to start it ?

[@tigermki]

@tigermki nevermind i found out great video

[@SOU6900]

And I thought that even start up was done from the comfort of the cab.

[@tigermki]

@jaggass turbo unit most likely

[@jaggass]

its a 150 litre diesel engine?

[@immortal1266]

Eu amo SD40!

[@shadowknight227]

@Train2590 I did, now. But I like a B40-8 start better.

[@elevatorfreak112]

ok well thanks

[@sorindncs]

@jaggass Locomotives DO NOT have a gearbox!

[@re49991]

@mt90945557 now ge has a tier 4 locomotive lets see emd beat that

[@RayVal53]

@foxden1992 Yeah well thats just people who dont have even fundamental knowledge of what a diesel truly is, especially one this massive.

[@dougd120]

but known for doing well

[@GeneralRELee]

can SD-40's work in dpu? or do they work as a MU setup?

[@jaggass]

whats the screaming is that the gearbox?

[@sorindncs]

Locomotives do not have a gearbox

[@sorindncs]

@foxden1992 In my contry poeple don't think that locomotives run on steam they think all the locomotives run on electricity

[@tigermki]

@Polybun and i found out what it was so get off my back about it

[@kaifriedrich1763]

Fallout 4 Intro

[@BroadwayLTDProductions]

Why? Because I don't like GE's? That makes perfect sense!!!!!!

[@thelogicalracer1036]

how is it a two stroke I think it would have to be a four stroke

[@CharredSteak]

Unlike the two stroke you might have in a weedwacker or chainsaw, the EMD two stroke still uses regular engine oil and the crankcase isn't pressurized. Since diesels have direct injection, only exhaust valves are needed. Intake air enters through the side of the cylinder at the bottom of the stroke and fills the cylinder which also gets rid of combustion gasses. Two stroke diesels can produce more power, have higher operating speeds, and have been known to have less mechanical failures than caterpillar four stroke diesels because of the substantial decrease in moving parts.

[@thelogicalracer1036]

Dominic Tellone okay thank you for the info

[@Rainhill1829]

Also, the aspiration is via either roots blower or EMD's own overrun clutched turbochargers.

[@thelogicalracer1036]

***** ok cool

[@tyfrank3427]

Steve Walker, General Motors made an entire line of 2 stroke diesel engines for decades. Detroit Diesel. Now they make 4 stroke engines as well. EMD engines are an extension of this line. General motors, on all their 2 stroke diesels, are designated by the number of cylinders-displacement of each cylinders. For example,there is the 6-71 which means 6 cylinders, 71 cubic inches per cylinder 426 cubic inches The supercharged only 6-71 normally has 238 horsepower giving tremendous volumetric efficiency. Likewise the EMD 16-645 means 16 cylinders that displace 645 cubic inches each. The 2 stroke diesels are always supercharged. They have sometimes 4 exhaust valves per cylinder which open at the bottom of the power stroke and the supercharged air from the blower is forced through the intake port in the bottom of the cylinder and forces the exhaust gases out. And then the valves close before the piston goes above the intake port and the blower and turbo (if equipped) force the intake air into the cylinder. Then it compresses with the piston travelling above the port. I disagree with Charred Streak that they are more reliable than a 4 stroke like a Caterpillar of Cummins as I have owned them all. 4 strokes have more torque than 2 strokes and run quieter. 2 strokes do not have fewer moving parts. Although they don't have intake valves, 4 strokes do not require a supercharger either. They have a full pressure lubrication system as a 4 stroke and use the exact same oil as 4 strokes do. I don't know about the locomotive engines because the only other application for the 16-645 I know of is the Terex Titan truck, but the smaller Detroits can be configured to run the opposite direction, and all parts that access is needed for can be moved from one side of the engine to the other, making the engine extremely versatile. A 4 stroke engine can't do that. Yet despite this, 4 stroke engines are way more popular today and EMD's main competitor, General Electric does use 4 stroke engines and the EMD's are going to 4 strokes now too, especially now that Caterpillar owns them and Caterpillar has produced 4 strokes capable of powering locomotives for years.

[@SchnelleKat]

16 cylinder two-stroke? Must be a Detroit..?

[@fatal-bert]

Kyle H82 it's an EMD 645

[@pahogger]

Very cool, the SD40-2 is one of the best sounding locomotives from EMD. Thanks for sharing!

[@Thetrucky69]

THIS IS THE TUFFEST ENGINE THAT I HAVE EVER HEARD. THIS SOUNDS TUFF.

[@jeffreymoss6329]

You should always run the layshaft through full travel once primed to ensure no sticking racks - helps avoid the excitement of an overspeed.

[@Thetrucky69]

EVERYTHING ABOUT THIS IS TUFF.

[@302derek]

sd40-2 's are bulletproof, they almost never have any problems.

[@TrainCamera]

This is in the engine room of the locomotive. This is turning on the main diesel engine..

[@gm16v149]

@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.

[@AUSSIETRAINDRIVER]

usually an idea to push the layshaft in to assist starting.. rather than allow the starter motors to keep turning until the engine fires.

[@strobx1]

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)

[@tigermki]

@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

[@silicon212]

@2008FORDF450V8 Umm, no. Sorry, the EMD two stroke 16-645E3 (what this locomotive has) is one of the most reliable diesel engines ever designed.

[@2008FORDF450V8]

you should put a cummins QSK60 V-16 engine would be a lot more reliable trust me

[@EETechs]

@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

[@Elicsrg]

eu eres conductor y otra cosa más es el mismo sonido que el un juego que se llama train simulator

[@doctorfeelucky]

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?

[@gm16v149]

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,

[@BroadwayLTDProductions]

Sounds way better than GE junk!!!!!!!!!!!!!!

[@shadowknight227]

@theGUYwho1 you get the audio file and set it up. Search for it on Google

[@beaman220]

What are you doing under my truck hood.

[@komododragon2007]

Who reved the engine at start up around 57 sec i know u did later

[@pumpmaster760]

@PhOeNiXpIoLe Electro Motive Diesel

[@elevatorfreak112]

was that the inside of the train?

[@AGDemo]

It's ALIVE! Bahahaha!

[@CentralALSirens]

he just want to hear it roar

[@tigermki]

what was that lever for choke

[@Pilotguy251HC]

I'm sure glad their lasting!

[@PhOeNiXpIoLe]

i sound like an idiot but what does emd stand for

[@WARD5KUSTOMZ]

thats looks to be a 645

[@tupai776]

WOW...nice sound...

[@ilikepie1974]

and you thought your truck had a big engine...

[@CentralALSirens]

OMG IT IS

[@stormspotter67]

intresting

[@MIZUch.]

Could you video an F40PH starting up?

[@menslady125eif2590]

So that's how it's done. I wondered how locomotive engines were turned on and off.

[@shadowknight227]

@Train2590 Yes! And with pride too!

[@Landaux]

What is the high pitch whining sound later EMDs there make? Turbo Charger?

[@Patriot1776]

Yep, turbocharger!

[@squidwardtentacles9276]

+Patriot1776 need that turbo on my diesel
