Union Pacific 6900 made its maiden voyage from Omaha to Ogden Utah in May 1969 to celebrate the 100th anniversary of the golden spike. 47 of these units were built, given the name "Centennial" and numbers in the 6900s.
These EMD DD-40X are the worlds largest single unit diesel locomotives. They have not one, but two turbocharged v16 diesels and 8 traction motors on 4 axle trucks. They had 6600 horsepower and a top speed of 85 miles per hour. The X in the model name stands for experimental. They are 98 feet long and were testbeds for technology that would go into future EMD products.
All of the centennial locomotives were retired in 1985 after hauling around 2 million miles each. Union Pacific 6936 was operated in the heritage fleet until 2016. There are currently 11 survivors.

If you go the wrong way and end up on an old man's property, he spoke like a tour guide and told us it is very normal for people to take the wrong turn into the garden. I swear best wholesome interaction I ever had.
I got to run the UP 6936 back in 2007. Well .... sort of. I worked for the Soo Line Railroad as a locomotive engineer at the Soo's former Milwaukee Road yard at Bensenville, IL (now retired). There is an annual event held around Memorial Day called Railroad Daze in nearby Franklin Park, IL. The Soo's tracks go by where the event is held and consequently brings down the locomotives several Chicago area railroads provide for the public to view on the outside and inside. It was in 2007 I believe when the UP brought in the 6936 for the event. I came to work on a late May, sunny, warm afternoon and there she was sitting on the service track at the east end of Bensenville (waiting to be moved to Railroad Daze the next day). When my lunch break came up, I used it to inspect the idling Centennial. Seeing that there was about 300 ft of clear track ahead I thought, "what the heck." So, I took off the handbrake inside the cab, positioned both isolation switches to "Run," inserted my reverser on the control stand and moved to forward, released the independent brakes and away I went about 100 feet, stopped and then tied it down. It wasn't a mainline run, but hey, at least I can say I operated the largest and most powerful diesel locomotive in the world!
Beyond impressive. The GM V-16 two-cycle diesels were around 10,645 cubic inches each. RPM was limited to about 950 because the reciprocating internal parts were so heavy and massive. These units were a sight to behold. For UP locomotives, excess power was never enough!
Union Pacific Railroad was known for its history with large powerful locomotives to get over those mountain passes. Examples included the Big Boys, the large Gas Turbine Locomotives and the Centennials. Today with modern locomotive control systems the locomotive in the front can control a chain of locomotives behind it. So we will likely not see these huge locomotives again.
I’ve been on that locomotive and the big boy that’s there. Before they were moved to their current location they were at a park and you could actually get on them both and get in the cabs. This was back in the early 90’s when I was a teenager.
Me too! My grandpa took me when I was a kid. Down at the riverfront.
I got a few photos of 6936 when she came through Portland about 2 decades ago... It's quite a sight! MASSIVE doesn't even scratch the surface.
Amazing
That unit's in the shop i work at. I'm going to get to do some electrical repairs on it. I hope my boss and i get to go run it on the fast track...
6936 was still in Union Pacific's excursion fleet with Big Boy 4014 as of November 2022.
The first three DDA40X locomotives had a horsepower rating of 7,000hp but they consumed a lot of diesel fuel and were sent back to EMD to have their fuel injectors swapped out to low flow fuel consumption injectors which decrease the horsepower to 6,600hp. This is the same 16 cylinder 645 engine inside of EMD's SD40-2 family of locomotives. Also inside of Union Pacific's famed fast forties SD40-2 locomotives Union Pacific use to operate with the Centennials on high priority trains and hot Z piggyback truck trailer trains from Los Angeles to the Midwest.
Thanks for the good info!
Yess!! And get that UP diesel with the oil tanker behind it
That was probably a gas-turbine locomotive. UP didn't use fuel tenders with their diesels.@@brianfrost7376
These used to roll by my house when I was a kid. Super cool to watch
Very impressive diesel locomotive model, the centennial class were a unique diesel model type owned solely by the Union Pacific rr.
That cab has SO MUCH room. Would love to be able to operate this bad boy.
Wish they would have built roofs over both engines.
I've been to that place in Omaha when I was younger
6936 just went to Illinois I believe
Their designation is actually DDA40X.
Superbe locomotive diesel 👍👍👍
I'm guessing that the Museum of the American Railroad in Frisco, TX is the only other place where you can capture one of these and a Big Boy in the same frame.
The Big Boy Steam Locomotive was large , This is collosal and a Beast of a Diesel locomotive 😮Damn , Impressive size and wow quite a walk to the front ,These must be the size of Two football Pitches 😮Think big stateside ,Oh yes ,Greetings from Scotland 🏴💖🇺🇲 Legends and Remember that TV series Monster Moves where one is next to a steam loco both pulled up a hill by Large trucks .Clue me in as to where these are ?😮
There's one of these in our shop and i'm going to do some electrical repairs on it...
That's a model I have to have!
Been there years ago. Great view of hwy 80.
Why the awfully irritating generic guitar music.
Using generic royalty-free music is a common practice for UA-cam creators.
@@westernrailfan88 There must be better pieces than this...
@@westernrailfan88 it's bad practice sometimes. like here.
maybe u misunderstood it. we don't have a problem with u using royalty-free music. we have a problem with having any music at all.
I’ll never forget the first time, as a kid sitting in the window seat , a yellow wall is passing, then a break , then more yellow…yellow, what was that? I went to find my dad!
if you havent watched the vids of them being moved and set at location, it’s a cool vid.
Great video
❤❤❤❤❤
💪🚂
And the worlds largest steam train next to it
What is that odd piece of steel hanging off the middle of the right rear truck? It looks like a rain diverter!
that is a portable re-railer.
@@rearspeaker6364 ok thanks!we have a main line right behind our Corp. Offices, and yrs ago, I HEARD a broken switch frog! The crew came within a half hr of me calling Canadian Pacific...I shudder to think what would have happened to us if that oil train had jumped the track...or the Amtrak passengers that use the same main line! The switch is about 150 yards away from my office window.
The diesel version of the Big Boy.
@@user-jp7rk1uf2n no doubt...but I'd like to see old 4014 in action myself! Bet that oil smoke would drive our NY governor CRAZY!!!
Super video, nice BIG locomtoive! MEGA LIKE & Subscribe
Hmm, I suspect two locomotives double heading with a little bit of CGI mixed in.
Which had more tractive force, this or Big Boy?
Nothing beats steam power! That's why we still have steam engines on the rails today! #GoBoilermakers
Nothing beats steam power from an aesthetics point, sure. But diesel electric power most certainly buried steam locomotives in every practical way. Efficiency, maintenance, tractive effort, flexibility, operating costs, repairs, etc.
@@FFred-us9tw is it safe to say each has their own advantages and our rail system couldn't live without both of them! They need that steam power to get over the high peaks! Otherwise they wouldn't be there!
@@johnnyfreedom3437 ??? we as a country can certainly live without steam locomotives. We have been for over 60 years. We are getting over mountains just fine with Diesel Electric
I think it's stupid that these are out in the elements instead of being enclosed in a glass house type building.
😮11 survivors………. I wonder if there are any in working order
6936 is being restored
😮
6936 is still operational
@@westernrailfan88 and garage kept!!
It's 90mph not 85.
Cab is locked?
