- The Worlds largest diesel locomotive the Union Pacific DD40X #6936 is turned on the old turntable in Cheyenne, Wyoming. The locomotive was built in 1971, weighs 270 tons, and is rated at 6,600 horsepower. This is a active locomotive mostly pulling excursion trains with the Union Pacific #844.

@TravelingTom Your link is broken!... error code 404...
I love the wail of the turbos. As with many of the big, slow turning diesels, you can hardly hear the engine itself, only the turbochargers! What a machine!
They are turbosuperchargers.... The clutches are still engaged making them superchargers driven off the engine. At higher rpm the dog style clutches disengage and the exhaust takes over
A lot of what you hear with an EMD is gear noise, surprisingly enough. The pump drive on the front, and the cam and turbo drive on the back end are all straight cut spur gears. I like the sound still, listened to it for 41 years. :-)
@@BilgeDweller .. Wow great info there ma Man .. .
@@robby844 .. You seem to know your stuff, Nice one Man .. .
...so THAT'S what that sound is(!)
The UP really takes the saying "go big or go home" to the next level
Big boy is another example
@@generalprincecodyhedgewolf2944 Union Pacific really loves huge locomotive, i guess....
I agree. 😊
Yep took the pipelines away
@@sutriosujianto5792It was kind of by necessity thanks to the Wasatch mountains, and Archer and Sherman Hills.
By the sound, outward appearance, and clean exhaust, obviously impeccably maintained.
...AND LIGHTLY USED-(?)
That's one of the coolest sounds ever when it revs up. Thanks for sharing this.
That iconic EMD645 sound. Then when it is at full throttle, that scream!
Wanna hear an even better sound, punch in Tehachapi (1990) sp coal train 13 locomotives
And people say diesel locomotives don’t have personality!
Oil companies : how many tons of Diesel do you want sir?
This DD40x: yes..
Airliners like A380 drinks around 2 litres of fuel every second whike cruising, during takeoff its around 3 litres per second.
That's nothing jet fighters consume 385 gallons per minute at afterburner.
Also the oil companies: “WOO HOO! We’ll have plenty of money to bribe a college admissions faculty member to get our average IQ kid into Stanford (or maybe Northwestern, CalTech or University of Chicago)”
How many barrels of diesel? Steam would be how many gallons of water.
..one ugly monster..back off kids..
Anyone else hear the 844 having a good time blowing her whistle? good to hear her again and see this legend.
It's actually the Roar from the turbos than the actual engine itself the sound clearly justified it's massive power its treat to hear.. Love from india♥️♥️♥️
Wanna see this and 4014 pull an 8 mile long train like an absolute boss. So much power.
theshapeexists you
ME TOO!!
Talk about POWER! 4014 and 6936 I believe are the most powerful locos.
@@eva.cassidy YOU BETCHER LIFESAVERS- THEY ARE 2 OF THE MOST POWERFUL LAND VEHICLES IN THE WORLD!!!
You need to remember that the 4014 is a very old machine, and it has spent many years outside in the rain!! You can't expect it to have the strength and stamina that it had when it was originally in service!!!
...I'm betting that the 4014 would explode if they tried to operate it at its full rated design capacity(!)
I work for Progress Rail and EMD prior to the company name change; also work in North Platte and seen these operate prior to this fleet their retirement. The 47 were built from 1969 - 1971and built at the request of Union Pacific in honor and celebration of the 100th anniversary of the laying of the Golden spike and essentially the 100th year operation of Union Pacific. UP also wanted these locomotives to be 100ft long from the front coupler to the rear coupler, but due to the constraints of the manufacturing plant in La Grange, IL, they could only be built 98 ft long. The fleet averaged 22,000 miles per month during the 1970's era as I have been told with some accumulating almost 24,000 miles per month. During that era, there would be a 4 unit consist. The consist was made up of 2 of these on either end with 2 SD40-2's in the middle of the consist. The Centennials would be connected such that the rear Centennial would be facing in the opposite direction of the front Centennial which would not require the consist to be turned. These would run from North Platte, NE to the west coast, primarily Los Angeles and then return. As the trains would come within 30 miles of their termination, the dispatcher would call and ask the crew how the consist was performing. If there was not a problem, there would be plans made then to quickly fuel and service the consist, and route them in the yard so that they could be used for the next train going in the opposite direction. These have 8200 gallon fuel tanks, essentially being two four axle locomotives on the same underframe. These accumulated in the neighborhood of 2,000,000 miles before retirement. These locomotives had a lot of equipment that are either unique to this particular model or experimental in nature which eventually became standard equipment. There is the UP6922, which is the road number that is used for the model train sets. The locomotive with that road number is in a city park at North Platte and resides along side of the UP3985, the one and only UP Challenger steam locomotive on display in the world.
I call BS .. can provide links to web pages documenting these statements?
Jesse C all true, do your own research if you don’t believe him
Jeffrey Paulsen..... Ooops! I think you meant to say the 3977 is on display with the 6922.... Not, the 3985 which is in the roundhouse in Cheyenne, and now officially retired from service and will never be under steam again. : (
3985 should be put on static display somewhere.
@@tomanderson3279 Literally NOTHING he states isn't common knowledge to anyone who followed the history of the UP and their motive power. Plenty of pictures of these in operation back then that back up his claims. Just do a simple search. The only thing i will correct him on is the length. UP didn't want these loco's to be 100' long. The simply insisted that they would NOT be LONGER than 100' for obvious reasons of logistics and curve radius. The frames were so long on these they were made by an outside contractor for EMD and yes, they barely fit in the buildings.
My father road this rail for 33 years
RIP Pop.
My Grandfather and my Dad were both U.P. Engineers and my Uncle was a U.P. Trainmaster. I really miss them all a lot!
Who would have thought that 2019 will again be a big boy on the rails.
What an absolute behemoth! Hearing the loud horn and the engine sound gave me the chills.
Thank you for the upload. Greetings from India :)
@Colorodo Strong lol thats not in india u must have watched some fake news channels
Its fake!! Watch when it's backing in, look closely at the chassis between 'union' & 'pacific' you can see it's just a hollow shell. Its a non functioning unit .. busted!! Though I still haven't figured out how it's moving with no engines, probably a tow cable just off camera.
The horn heard is most likely from the steamer firing up at the end of the clip.
@@tomanderson3279 Really.... learn a bit before posting tripe. There is a passageway between the two engine compartments....
Tinoo I thought the horn sounded like one from a steam loco.
It's basically 2 locomotives on one frame. Imagine having to run that thing long hood forward.
Basically a nightmare in hood forward mode
need a spotter up front, at 60mph!!
Sounds like something only NS would do
Filler up please. Sure thatll be $100,599 dollars And 34 cents, cash or debit card lol
That's why we here in Sweden have the cab sticking up over the hood.
Awesome! Seeing the largest most powerful diesel locomotive ever built.But hearing 2 645 V16s is even more amazing! Glad Union Pacific preserved and uses one of these EMD behemoths for excursion service!
*32 CYLINDERS!*
@@LegoWormNoah101 Yep!, two V16 of 3300 HP.
Most powerful American diesel, at least. There are stronger elsewhere in the world, especially the all electric freight locomotives.
@@ve2cnl.... They were originally set at 7,200hp... but the extra fuel costs, outweighed what they gained in power, so they were de-rated 300hp each, back down to the 3300hp ratings.
@@Romans--bo7br The DDA40X was never built as anything more powerful than what it was. From the first unit delivered to the last the HP never changed. Ideas on increasing the HP above what it is were discussed in the planning stage but they never made it into production. And it wasn't even the slightly higher fuel consumption issue that stopped them from doing it. It was reliability and traction issues.
This is the Big Boy of the diesel world..... wow
...AND THIS ONE DOESN'T HAVE ALL OF THE MAINTENANCE HEADACHES OF A STEAM LOCOMOTIVE(!)
@@daleburrell6273 and it's made with precision parts.
@@mattlf9120 I suppose-!!
@@mattlf9120 Of course implying that steam locomotives didn't have "precision parts"...which is an obvious fallacy.
@@robertgilmore8339 steam locomotives had plates stamped out, rolled and riveted, very crude by today's standards.
New locomotive frames are cnc laser or plasma cut, and welded in a jig, panels are also cnc laser cut, then bent with a pressbrake which is also cnc controlled +/- .003 of an inch.
Modern parts interchange 100%
100 years ago parts were fitted to the machine with almost no interchangeabilty.
I actually worked manufacturing for years, so what's this "fallacy" you speak of?
I dig the horn. Like an old Steamer. This is a diesel incarnation of a BigBoy. ; ] Fitting that it's Union Pacific.
Bill Holt.... Just so you know, the Whistle you heard, sounded like a "steamer".... because it was. The 844 was outside the roundhouse, getting ready to go out on another "tour". The 6936 never sounded the horn in this video.
I remember seeing this behemoth rolling north through Kent, WA, many years ago. Once seen, never forgotten. I climbed all over another in Portola, CA. All you can do is shake your head at the kind of audacity that would create such a machine.
...I WOULDN'T CALL IT "AUDACITY"-(!)
I was able to see that DD40 at the Portola Museum as well. Got to climb aboard and see inside the cab (without any other people or kids making noises) and take some pictures. I think I was actually the only visitor at the museum at the time I was there. I was able to drive two locomotives. I had a picture of the DD40 locomotive in Panaramio or Panoramio which was used with Google Earth before they shut down Panoramio. I should try and get the picture back up in Google maps and Google Earth if I can find the picture.
Me Railfanning:
Me: oh I hear a locomotive, think its a CSX GP40-2.
Train: (comes around the corner)
Me: HOLY SHIT!! THE HELL IS THAT??!!!
Wow thats some locomotive. I've never seen an 8 axle one before. I imagine that beast can pull thousands of tons of freight easily.
Sadly probably only pulls passengers now
A Beast...grew up around trains...dad worked 4 railroad, husband working on trains....loves the sound....lady loves trains...
Love those Centennials. Watched them many times in late 60's pulling hauls out of Los Angeles.
Wow. She's a big girl. "Yes, the force is strong with this one."
As much as I love steam locomotives. The diesels seem alive too. Mechanical beasts of awesome power.
I was fortunate enough to catch this motor on a VIP special, SAVBL-14 in 2008. From Parsons KS to McAlester OK. (MK386 to MK566). It was quite the ride. This thing will cruise at 70mph with little to no effort. However, I have to say it is the roughest riding motor I've ever been on to date. This thing will beat you to death.
Crap tracks in that area. That line is used for freight, no pax service. In the 21 years I lived in that area, I only saw them once redo the beds and replace rotten ties.
Nighthawke70 What time frame were you in the area? They undercut and re tie the Cherokee and Choctaw subs every 5 years. This is a major Texas coal corridor. Dont get me wrong, it's not 100mph track, but it'll handle 50mph coal buckets all day long.
Guess you have never ridden in the cab of a Baldwin before... If you had you would change your opinion...

My Favorite locomotive! Such an awesome honor to see one working and sounding perfect!
That UP car....it's not a toy. Its actually quite large in fact, but the DD40AX.....dwarfs it. Stunning🇺🇸
I rode on one...my Grandfather and uncles all passed now worked all there lives for union pacific...they all died wealthy...railroad treatment was really good.
I guess this old girl has been rebuilt more than once. I grew up on a main east west line of UP through the Arkansas River Valley next to the tracks. We even had the original rail bed left over from the 1800s line on our land near the river. I am glad that she is still around. I was built in 1968.
This sound is so soothing. If I ever wake up too early, this helps ease me back to sleep 🙂
Finally got my hands on one of these in N scale. Should get some interest at my club!!
Me too, just a month ago in jun 2019. And i want a second one with a different road number. In the Netherlands were i live, US rolling stock is rare and this one is very rare. In 20 years of railroad modeling/internet use for the hobby, i only saw 5 passing by on the Dutch N scale market.
Jp I have 3 in n scale 2 are spectrum models 6941 and one is a Bachman 6926
the most wonderful locomotive ever built! respect that it is preserved in working condition. I love to run in in Train Simulator
I believe the Illinois Railroad Museum in Union, Illinois has one of these beautiful giants in their collection
It does and I've climbed all over it. :)
Thanks! Found it, Kenefick Park.
Union Pacific #6930
@Doug Kirk y0l
There is one in Pomona, CA at the Railgiants Museum. Where the 4014 lived before its restoration
That beautiful 645 sound brings me back to my childhood
Its good to see its still kept in running condition. While it would make an awesome museum piece, its better to see it in action.
Absolutely agree. As an engineer who works around a hospital power plant, I love big machines. It just breaks my heart when I see old rolling stock, but especially old locomotives, rusting away abandoned in some yard or on a forgotten spur line. I always wish there were ways to rescue ALL of them and restore them to their former glory.
YOU BETTER BELIVE IT!SHE IS STILL A CLASSIC DIESEL!AND FOR HER TO STILL BE RUNNING AFTER ALL THESE YEARS, IS TRULY AMAZING! SHE LOOKS GREAT ,AND SHE SOUNDS GREAT,TOO!
idk why I hear the Thomas and friends turntable song in my head while its spinning....and watching James spin like a top. lol.
That's an old episode
That's an old episode
Without question my favorite locomotive. On my bucket list to see
That must be some feeling sitting up in the cab of that machine damn.
Swinging 260 tons like a champion..
Don’t you think that is a bit overkill for moving a baggage car around a yard?
It’s For show duh 🙄
Super power switcher. ♡ T.E.N.
This will help you understand how she is used.
en.wikipedia.org/wiki/Union_Pacific_6936
No
I mean....if you had a choice between a little switcher and a DD40AX....wouldn't you? ;)
Looks like a 2-in-1 loco! Very impressive piece of engineering!
Holy shit I thought this thing was a myth it's like 2 units in one
No myth. There's a number of them scattered around the country in museums. IRM in Union, IL, National Rail Museum in Green Bay, WI, Museum of Transport in St. Louis. And it pretty much is two units in one; UP did a lot of experimentation with that idea years ago. Got to see it in person north of Peoria, IL in 2008, quite the beast. en.wikipedia.org/wiki/EMD_DDA40X
İt's 8.000 horsepower
6.600, Mehmet. Each 16-645E3A was rated at 3, 300 horsepower. If you tried to run rack settings to get that much power, things would start coming adrift. :-)
It is two units in one. It is pretty much two GP40 locomotives, 3,000 horsepower each, assembled on one giant frame. I believe this is the only one still in operation, though others are preserved.
Farmboy Gaming yep, that’s exactly what it is
so good to see , i used to work on the UP M&W , and see consist of 6900 - SD45- 6900 what a sight it was never forgot it
I am so pleased that this milestone engine is still in operation. Now all we need to do is to get one of those gas turbine engines going too. These are the sorts of things that DID make America great.
If UP wanted to, I'm sure they could. I'm sure the 4014 Big Boy project takes top priority at the moment.
No, America was already well on the way out by then. We are still making plenty of impressive stuff technologically speaking, but not like when we were the real leader in the world. We did that ourselves. Intentionally. The best way to make lots of money is to show the rest of the world how to copy us, and we can make money trading with them. We will worry about the long term results when the long term comes. Now it's arriving.

This is my absolute favorite locomotive from the new era thank you very much for posting
You are welcome.

Those are the turbochargers that your listening too,two of them to be exact,one for each of the V-16 engines.This road diesel holds 9,000 gallons of fuel by the way.
@@4gauge10 probably more then two. This loco has 2 prime movers, and if I am not mistaken the 645's have a turbo per cylinder bank.

I'll just say I've seen this locomotive on an earlier video on UA-cam I think it produces 12,000 horsepower with a two engines it has in one engine it's the biggest they ever made thank you.
It’s 6,600 HP. Each engine produces 3,300 HP
@@FFred-us9tw thank you.
One of the most interesting jobs in Locomotive maintenance was spinning engines on the turntable, if you screwed up, you'd know about it.
I love these machines, they are incredible ….
That locomotive is HUGE holy cowl
Look at the riveted construction of the turntable: That shows it was built BEFORE the 1950's. It is REALLY OLD !
It was built in 1941.
Honesty Counts The turntable was built for the UP Big boys.
It sounds old too...
So handling this much weight was no sweat when it was new, The Big Boys and tender weighed twice as much.
what does it weigh-how long-tall is it
Union Pacific is a LEGEND FOR AQUIRING P-O-W-E-R!!!!!
God damn that's a pleasant sound.
...I WONDER IF THE OPERATING CREW THINKS SO?! THEY ARE RIGHT ON TOP OF IT!!!
That's one big mother of a Locomotive ,Size is everything looking at this big behemoth of a beast of US Traction 😮Wow ❤️❤️🇬🇧❤🇺🇲
I would love to see that thing start on a cold day. 😁
cellogirl11RW They Probably never kill it! 🙀🌈 100 miles per gallon! Uh, 100 gallons per mile!
I'm sure the little boy seen in the cab of 6936 was getting the ride of his life! What a thrill! Very nice.
My favorite diesel locomotive
Diesel ELECTRIC locomotive, you moron!
Just the sound alone of this beast is enough to let you know that it is the biggest badass most powerful diesel loco on the face of the planet! Very cool vid!
Diesel ELECTRIC locomotive!
UP's got themselves some real gems, don't they?
Yes they do!
Union Pacific should have started on the big boy a decade ago, then they would have the time to complete the heritage collection and possibly have time to get x-26 GTEL restored, imagine that at the 2019 golden spike celebration. Big boy, big blow, and big jack. Just like the poster when the centennial came out “BIG THEN, BIG NOW 👍🏻”
Fun fact. Power (pulling strength) of a locomotive is not limited by the size of the engine. They can all be fitted with bigger engines. A locomotive's maximum pull is 25% of what it weighs. It is a traction issue. Weight is the factor that determines how much a locomotive can pull.
Exactly right!
They need to put Big Boy 4014 and DD40X 6936 together!
That would be a lot of horses!
This 2 stroke beast is turbocharged and superchaged! Amazing engineering. Only in America!!!
That's about 5 megawatts of electricity.
Joe Bledsoe it has potential power to feed a small city easily
@@luciocosta8155 Do all the wheels have traction motors, or do they have a dummy wheel? I would love to see the bogie without the engine.
@@ferdinandfrancis9673 all axles are powered... remember this was 1969 so 8 traction motors were needed to put that much electrical power to the rails. It's only recently that 6 traction motors could handle that much power, and using a/c power to boot....
I can watch this stuff all day we put our sound system on every time and would give anything to ride on her for a day
This unit looks like two SD-38's built on one chassis.
Richard Gerlach I
+Ian Moodie- What?
Its 2 GP40's, literally. The 38 and 40 series have different engines.
+Zack Boone- I figured it was a 40 or 38. The rear end looks like a 40 and the left front (behind the cab) looks like a 38. I called Heads. Came up Tails. Thanks for the info!
GP40's. And the DD35a was twp GP35's on one frame. I love the DD units. There is a DD40X not too far from me in a rail museum. Need to get up there and take a look.
I live in Summerville, Ga and we have an operating turntable in our city. We have steam trains come down on weekends from Chattanooga during the Spring and summer and also during Christmas.
I was at EMD LaGrange when this was built. 103 long over the coupler pocket but the erecting bay was on;y 100 feet column to column. They used two 250 cranes and moved it station to station on an angle. Finally straightened out at the truck station and then forward into the air brake shop. Two special 645 E3 engines. 3300 HP each.
I have the original Maintenance manual and spec sheet here in front of me. These were 98.5' from coupler pulling face to coupler pulling face. So the frame pockets were less than that. But i know the stories of the challenges it caused during construction.
Cannot beat that EMD sound, esp the 16 cylinder 645!..
It’s a big magnetic compass trying to point north.
Their getting it ready to go pull on Superman’s cape.
Bill Bright ua-cam.com/video/E0iIlE5P7XY/v-deo.html
I built this exact roundhouse and turntable style in N scale 40 years ago. Never seen one work for real lol.
You can count on UP doing it right and doing it BIG!
That thing is huge. Probably could handle a monster train of 300 cars by itself.
When I went engineer school we had a different calculation for tpoa,tpa, tpob for this bad boy
Tropical paper engineer with no professional record can only recall courses, not actual work.
I'm impressed but still in love with the Big Boy. 😊
2 GP40Xs on a common frame.
This is really something too see.
I can't imagine the horsepower and torque it has
It's powered by Two, 16V645 E3A prime movers - or - Two, 16 cylinder engines with 645ci per cylinder (9-1/16" X 10" B&S) each with single Axial flow turbocharger, 45 degree with "fork & blade" connecting rods, coupled to the engine via the cam drive & thermatic clutch. With the exceptions of No's. 6901 & 6902, they were delivered at 6600hp (3300hp per prime mover)... 6901 & 02 were delivered rated at 7,000hp with 20% over, injectors... but were de-rated back to 6600hp with the 10% over, injectors.
The 6936 in this video (and the only one in active service through the Heritage fleet operations), has been de-rated further, to 6000hp since it was retired from active "hot shot" freight service, and used strictly for "Special Moves" help save fuel costs as much as possible, considering it's usage in "retirement".
As far as torque, each prime mover, rated at 3300hp at 900 rpm should develop about 19,257 ft lbs of torque. I know that the 20 cylinder 645 engine, rated conservatively at 3600 hp, developed 21,008 ft lbs of torque at 900 rpm.
"Listen to the engine, the rumble, and the roar ....." From the song Wabash Canonball. Hear this rumble .... feel it ..... love it!

Huge & powerfull machines, american style !! What a beauty !
I love it
however impressive, it is still a diesel, after all. thanx for sharing.
Wow. That sound of engine is fantastic!
Brilliant I thought all turntables were gone ages ago. It's great to watch the diesel engine on it. The vintage steam engined come out maybe four times a year. Thanks.,😃
Not many turn tables left. Even the ones that are still around and not used very often.
That's just all the power in the world inside of a box

@@rearspeaker6364 amazing how they manufacture these heavy items is incredible, even more than 100 years ago they made such big equipment. Look at the documentary about building the Titanic, people have such wonderful skills
I've been wondering if I would ever see an eight axle locomotive anywhere except Brazil. Thanks!
There are locomotives like that in Brazil that takes a American locomotive shipped from America like a sd70ace or sd40-2 that's would sometimes be converted to have 8 axles instead of a 6 axle frame
This is some of the good stuff Humans do, think invent, build , overcome. We can do some cool stuff!
...THAT'S THE TRUTH-!!!
Nice recording of the DDA40X, the biggest EMD product ever made with two separate supercharged V-16 645 engines. 8 axles and the biggest diesel-electric on record.
It uses Turbochargers, not Superchargers.
@@FFred-us9tw
I know all EMD 40 series diesel engines were turbocharger powered. I read in Trains magazine to get those two separate engines up to 3300 horsepower they had to build superchargers for them. They were the only ones built like that. They really saw no more use for a supercharger after that one model and returned to standardized parts. They were in a battle with GE and failing Alco.
@@dblkrailfan not sure what article you read because it sounds like you may be confused, but I assure you these engines use the typical EMD Turbochargers on them. I have the engine and maintenance manual for these loco’s sitting on a bookshelf behind me. Traveling Tom (who posted this video) also has an in depth video about these locomotives where you can actually see the turbochargers on them.
Truly the titan of trains
when the engines last wheels left the turntable @3:41 the camera jerked
Thanks- I needed help falling back sleep. 👍
Can't wait to see the centennial in the Silvis shops back in action
Esa si es una gran locomotora 👍
Sat in the cab of 6936 at the Portola Western Pacific RR museum
When 6936 showed up to our shop my boss and I checked out the electrical cabinets. I'm going to get to fix some electrical issues on it this year. I've been trying to convince the museum to let me rewire the thing. lol
Nice DDA40X
UPRR is great at preserving vintage and historic power!
They had the monster ALCO U50’s but unfortunately none survived…..always thought how great if one of those was still operating 😎🇺🇸🇺🇸
That's one big beautiful beast. Wonder how often, if ever, they fire up the second prime mover.
Both engines are always running. I do not believe you can run the locomotive on one engine.
There is almost assuredly a way to operate the locomotive with one engine running, in case the other was to fail enroute.
They always use it.
they actually used it to haul a grain train that had it's power break down. this happened while it was out on a heritage trip.
ua-cam.com/video/71JsIhh4jDc/v-deo.html
In that video at around 2:06, there's an isolation switch for both movers. I assume that would mean you could operate it with only 1 engine.
Such a gigantic locomotive !
