[@jeffreypaulsen8848]

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.

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.

Look at the riveted construction of the turntable: That shows it was built BEFORE the 1950's. It is REALLY OLD !

[@travelingtom923]

It was built in 1941.

[@timothybarham6374]

Honesty Counts The turntable was built for the UP Big boys.

[@praestant8]

It sounds old too...

[@gregrowe1168]

So handling this much weight was no sweat when it was new, The Big Boys and tender weighed twice as much.

[@heatherallan2695]

what does it weigh-how long-tall is it

[@GERRYMALONEY47]

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

[@travelingtom923]

You are welcome.

[@randymagnum143]

God damn that's a pleasant sound.

...I WONDER IF THE OPERATING CREW THINKS SO?! THEY ARE RIGHT ON TOP OF IT!!!

[@ronholtz4882]

I love the sound of those diesels and turbos. Damn.

[@shyryTsr2k]

I live right in front of a train station, with train tracks almost in my backyard with a fence, not wooden, separating my yard from the tracks. I legit have to speak louder whenever a train comes by and blared the horn almost right in front of my house when I speak to someone smh. It's also how I became immune to most noises hearing the train horns at 4 am😅

[@mattblack9069]

Do you have ringing in your ears?

[@donnebes9421]

mattblack huh? What did you say?

[@jds6206]

I'm sure the little boy seen in the cab of 6936 was getting the ride of his life! What a thrill! Very nice.

[@stokerboiler]

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.

[@FFred-us9tw]

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.

[@musicforaarre]

I searched for a video with this locomotive by itself so that I could hear it ! I just LOVE that throaty growl. It gives me goosebumps. Thanks so much for letting me hear it . Aarre Peltomaa

[@jacobforsman3897]

I know what you mean, but you should also check out the sounds of the deltic diesel-powered British locomotives, such as the class 37s. They have an even more guttural growl to them, I think, because they didn't have the same noise regulations in the UK. At least that's what I've read from other people's posts, concerning the noise restrictions. Also, typical computer and cellphone speaker don't do the sounds from the deltics justice. You really have to hear them in person to appreciate it properly. Some people have said it reminds them of the hair-raising growl you might hear from a big cat.

[@Romans--bo7br]

@@jacobforsman3897 ....those British Class 37's sounded like 6 cylinder Cats in the old style D8 Bulldozers.

[@joebledsoe257]

That's about 5 megawatts of electricity.

Joe Bledsoe it has potential power to feed a small city easily

[@ferdinandfrancis9673]

@@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.

[@68Jaguar420G]

@@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....

[@mrbill3576]

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

[@Muggar62]

Best looking loco ever built.

[@michaelwthalman]

Reminds me of back in the 70s watching trains in the Council Bluffs yard. DDA-40X, DDA-35,DD-35, U50 and U50c. I still will occasionally see 6936 sitting in the Council Bluffs yard.

[@robertmuckey887]

well the dd40x still sounds like it can take sherma hill anytime

[@deetjay1]

Just watching an old turn-table is a treat...Only saw one once at the FWD yard in Childress TX...

[@steadfastcoward]

These were in regular service again in the 90s? and passed our old depot all the time but never stopped :(

[@chuckg2016]

"Listen to the engine, the rumble, and the roar ....." From the song Wabash Canonball. Hear this rumble .... feel it ..... love it!

[@richardgerlach5156]

This unit looks like two SD-38's built on one chassis.

[@mdnim]

Richard Gerlach I

[@richardgerlach5156]

+Ian Moodie- What?

[@zackboone15]

Its 2 GP40's, literally. The 38 and 40 series have different engines.

[@richardgerlach5156]

+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!

[@Shane-Singleton]

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.

[@shubhamsarkar2186]

This thing is actual AmericanMuscle. Its not just any machine its a beast.

[@eva.cassidy]

That would be a lot of horses!

[@aidancprailrailwaystuffeng4612]

That locomotive is HUGE holy cowl

[@emdmanSpaziani]

I've operated a lot of EMD locomotives in my 27 year career and I would give anything to operate a Centennial they are and engineering marvel, and I have also run many different ge's and I would not give a plug nickel for one of them no matter what the model.

[@travelingtom923]

Hopefully in the future a museum can get a Centennial operational and offer a "engineer for a hour" program. I think it would be a big money maker. I know I would offer quite a bit to run one of those monsters.

[@emdmanSpaziani]

And i'm sure it would take a lot less to get one of those back in road worthy condition than the Big Boy. cant wait for that to get running.

[@travelingtom923]

Yes it wouldn't be that hard. Both engines are very common and can be found on any 16 cylinder EMD locomotive made from the late 60's until the late 80's. The electrical and other components can be found on just about any EMD locomotive.

[@theq4602]

I hear that they are very smooth riding because of the extra set of wheels on each truck. As to letting the average Joe drive one. No not unless its on a closed track not connected to any railway line. I know of way too many people who would hijack it just for the hell of it. Most of them are below the age of 21 though :D

[@Rooster1Cogburn]

Yes, the Centennial is a smooth machine. It's good on the straightaways but doesn't handle the curves so well. 5-years experience on one.

[@mikepillman2266]

Thank youi UP for preserving this example of engineering. I wish that a working GTEL was still around..

[@briansmith8967]

I get goosebumps every time I this beautiful beast. It was at one of the Railfairs at Sacramento in either ‘91 or ‘99

[@xhetoomni8134]

That thing is huge. Probably could handle a monster train of 300 cars by itself.

[@shariys1]

UP's got themselves some real gems, don't they?

[@travelingtom923]

Yes they do!

[@brettkoller7636]

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 👍🏻”
