Had to reupload this because it wasn't showing up on my channel page for some odd reason. I think something glitched in the uploading process, otherwise idk lol

As a Hungarian (as Hungary's premier locomotives were the MÁV 324 2-6-2 and MÁV 424 4-8-0) its still amazes me how big soviet locomotives looked like. Rather than improving their effectiveness they just scaled them up and in the end they looked very top heavy and bulky lol

This engine... was a groundbreaking invention 🥁🥁

I wonder if the AA20 would have actually worked on the Union Pacific's track (assuming it was regauged accordingly)? After all, the Union Pacific had the 9000 class (4-12-2) in active service from 1926 to 1956, which is pretty good for US steam locomotives.

Great video as always. Did not expect that the AA20 would be based off a largely forgotten UP loco. Also the use of the Bocchi the Rock! gif at 2:04 was absolutely perfect

I have heard about the Russian’s 4-14-4 locomotive, and that it had some issues. To me, it appears to be either the same size, or a bit small than the Southern Pacific Cab Forward 4-8-8-2’s, which only one survives, that being 4294 at the California State Railroad Museum. I have seen that locomotive a lot at the museum, since I live not too far from Sacramento, California.

The fact is that the AA20 proved that 12 Driving wheels is the biggest a rigid frame Steam Locomotive could get!

I always am fascinated whenever I see videos and hear stories of this unique engine, despite how infamous it was. I honestly believe that this engine would've been worthy of permanent static display.

Finally I get communism and train content in the same video.

The aa20 was just too crazy of an idea to work. The 9000s were bad enough as is, so it was more of a question over if they could do it than if they should do it. I liked the little segment of Katyusha at the end.

1:09 Are you suggesting that an experimental locomotive dreamt up by some recent graduates from the Moscow Institute of Transport Engineers was SOMEHOW built in Germany? IN 1931?! You do realize when that was, right? Did you, as you were copying these lines from the Wikipedia page, not notice the "citation needed" mark next to them? Just so we're clear: no, it wasn't built in Weimar Germany. The Voroshilovgrad Steam Engine plant handled the entire project. Even blueprints from sketches provided by said young engineers were made there.

“I am heavy train guy, and this is my train. It costs 400,000 dollars to drive this train for 12 seconds.”

Best rail straightener

Glad to see this video back up!

I have nothing to add information wise like the others, but the choice of music in your videos are always on point!

The Omori editing shocked me a little, haha! Lovely video on this thing. I usually rag on it for being such a failure, but it really was impressive lolol

but in the end the Soviets understood instead of building big steam trains to pull in more cargo. it is easier to replace them with electric trains which can have more power than steam trains and diesel trains. 1990 50% Soviet rail way is electric. and transports 80% of the cargo. compared to the United States which is only 1% in 2022

Thank you you too recommendations, now trains are going to be another KZfaq rabbit hole I go down!!

I like ridiculous, experimental locomotives. They're freakin fascinating

I know it's not really that related, but I wonder what UP's 4-12-2s would look like if they lowered the headlight to the center of the smokebox. And then put the air compressors on the side like some of them had.

Would love to see someone talk about the electrification of the Soviet rail network. It's one of the most impressive achievements in rail history and, not to get too political but, it's arguably the only reason Russia still has an economy, but every mention of it I see just takes the wires for granted.

"should we build a practical and useful engine?" "Nah, slap as much wheels on a rigged frame that will possibly fit on the engine"

There are quite a few videos about this locomotive, how ever, you have video and pictures I have never seen before. Thumbs up.

AA20: “Looks like those tracks could handle the Neutron Style!”

I love Soviet Steam locomotives. The Red Star Is too Iconic, Especially E class 0-10-0's. Shame The AA20 Wasn't Preserved

Excellent subject matter and footage.

Was not expecting to see Bocchi in a steam locomotive history lesson but I'm here for it

I love this video. Anyways...nice usage of Bochi the Rock anime GIF!

I'm from Dunkirk. Good piece of history. ALCO-BROOKS was once the heart of our town.

One thing comes to mind when I think of Russia: The Heavy from TF2.

good use of Kass' music!

I would say you did a great job, but since this a video about a Russian train I have to say *we* did a good job. ;)

Great video

I would love to see a video done about our P38 class locomotive. Unfortunately none were saved from the 2 or three built. But it was the largest articulated locomotive in Russia and I believe it would have been similar to the Yellowstone types. Sadly There are no articulated locomotives running in Russia. But we do have a ton of great steam still. Many are used for passenger and limited freight service

3:52, if the AA20 really did only have 63 inch drivers then WOW, these guys are only 5'2 maybe 5'5 on a good day.

Some might call this train “ground breaking”

10 seconds into the video and I hear Zelda's Kass theme 🤘

ALCO was like Oh hail nah they don’t got a bigger locomotive so then they built the challengers and big boys

now this yes.

Stalin was obsessed with big. Tatlin's Tower, the Seven Sisters, Maxim Gorky, T35, etc. etc.

Split it in half, now it’s a 4-7-7-4

Katyusha in the credits? Spotted the GuP fan

Awesome

R.I.P. AA20 4-14-4 1934 - 1960

Well they did expand their track network at the same time though. Much more than they invested into locomotives actually.

2:06 it is a shame that the glitch sound is not included

In your next video, are you gonna talk about the new Amtrak Airo? I can’t wait to hear more history.

US: Amtrak USSR: Ourtrak

Wow! A steam locomotive that actually destroyed the tracks it was on because it was so heavy!

Imagine a universe were they saw the big boys in stead of 9000

It is the ultimate compensationmobile.

They should have turned it into a museum piece.

Can you talk about Railroads using Dark Territory? One notable Railroad that I know of that used Dark Territory was the Rutland Railroad in Northern New York and Vermont State

"Humph!" Said the Fat Controller. "I never liked these big engines, always going wrong."

Why did they ever think they could go through switches with 7 axles on a solid frame?!

1:02 **raid shadow legends intensifies**

Can't get enough of random #sega #sonic! 👍👍👍

I made a drawing of a 10-10-10-10 and it was cursed af and it was also streamlined

0:46 There I am, Gary!

The reason why i Call this locomotive Andrey Andreyev is because a politician of the same name has sponsered it’s construction.

The Russians never did really adopt more successful and practical articulated steam power, they did produce a 2-8-8-4 Yellowstone type in the 1950's that was successful but it was only a prototype and by than steam locomotive production in the Soviet Union was curtailed. The Russians always preferred steam locomotives of 10 coupled designs for freight service. Sadly the AA20 was doomed from the very beginning.

In engineering, bigger is not always better

You’re telling me the Soviets built something too large and heavy for its intended purpose? Color me utterly unsurprised.

Nice use of the "Bocchi glitch" scene!

I Would love to see a video about Soviet passenger rail

I would love to see a G scale version of this engine for model railroaders.

I wonder if these events inspired N&W's J Class Aluminum Rods to be deemed Top Secret?

It would’ve been interesting if it had survived into the modern age and if it met up with big boy to see which one was the crazier loco

In mother Russia you don’t drive steam locomotives, steam locomotives drive you

they had some 2-10-0 from baldwain 200 got left in the us due to the revilution

Imagine an e2 but it powerfully like big boy+aa20

That locomotive looks a lot a niagara except a bit um L E G I T C H U N G U S but still nice video Jared keep it up

"Why lay more track when you could just haul one giant train?" Good to see the modern railroad industry takes cues from the notoriously successful soviet union

The smoke box really reminds me of the NYC Niagaras

The Track Destroyer AA2

Love the bit at the end kalinka

Just goes to show that bigger isn't necessarily better.

The 9000s and Hungarian 2-12-4 tank engines (yes that actually did exist) were probably the limit of non articulated locomotives as the 9000s were actually quite successful

Soviet Union: We do it bigger, but not better

Do the video of the Soviet M62s, 2TE10s and 2TE116s next

Such an interesting locomotive by far and one thing you didn’t mention was that it had special heating apparatus in its tender to minimise the water from being frozen over during trips in the harshest winter conditions on the planet. I think a lot of the Russian steamers had this apparatus onboard, but there was something about the AA20 that made that technology special. I remember reading it in my vintage 1940s and 1950s railway magazines. It’s interesting to note that if Mikhail Kalashnikov pursued his dream to design locomotives for the State Railways, than rather going forthwith with his second idea of building the legendary AK-47 Assault Rifle whilst recovering from wounds sustained on the Eastern Front as a Tank Commander, imagine what he could’ve built if he had the chance to put his brilliant engineering mind to work. I’m sure the legendary gunsmith would’ve made an awesome Freight locomotive for his vast countries railways. Great video once again, my friend. I do absolutely love these videos especially the one you did on the Whyte arrangements, that was so interesting by far considering the ones about the Berkshire of which the South Australian Railways had the only Berky design in the country, the formidable 720 Class locomotive. But we also had the Pacific type locos such as the Class 600 and Class 620 Heavy & Light Pacifics, we had Mountains later modified to a Northern (aka 500 Class), we had another Northern Type, the 520 Class that took inspiration from the T1s of the Pennsy in your neck of the woods, we had almost 50 Mikado type locomotives of the 700, 710, 740 and later the ex. N Class of the Victorian Railways aka the 750 Class 2-8-2s. Thankfully, a few of these behemoths have been preserved with one of the 520s undergoing restoration to operation at SteamRanger in the Adelaide Hills of Mount Barker. Perhaps you could do a video about how the strong American influence dominated in the designs of the big power South Australian engines from the 1920s to the 1940s? If you need source material, photos and video just hit me up 🤙. Anyhoo, I’ve probably bored you enough now, I apologise. Have a wonderful and safe Christmas with your family. Regards, Caleb from South Australia. Peace brother ✌️

Too big to fail, blasted off the tracks!

2:03 Aaaaaand it was a complete disaster

Go big or go homesky!

I’m just imagining that the Southern Pacific SP-1’s and SP-2’s and the Union Pacific 9000 Class Locomotives laughing at the AA-20.

There was a giant Beyer Garrett built for Russia around the same time. Can you do a piece on it

Waiting for engines of the trans-siberian railway

If The The TF2 characters were locomotives, Heavy would be The AA20.

Can you please cover the P36?

@amtrakGuy365 What are the "lateral motion devices" you mention at 2:52? How did these work?

Union Pacific learned this lesson early that's why we got the 3900 class and the 4000 class Big Boy articulateds

It would’ve been interesting if an American railroad company would’ve bought it and brought it over to the states

Why am I getting a feeling after its failure that Andrey was sent to gulag by Stalin. Great video Jared! Where did you find the footage of it under operation?

They could've just turned the AA20 Into a 4-6-6-4 Challenger or something

that is why the Big Boy locomotive was articulated

I wonder if the soviet railways would have gotten the optimal design for a super powerfull steam engine (not counting the two engines that came after) like, maybe they coul have made a 4-10-4 or 2-12-0 or maybe even a 4-8-8-4 design, one can dream.

Imagine if they'd seen the Big Boy or Challenger.

"So this engine doesn't have a name so we'll call it EEGOR"

Russian engineers: “Woah look how many drivers that thing has! This is the one we’ve been looking for!” Little did they know that there was something bigger…

a 4-12-2 is just a little over the top. a 4-14-4 is overdoing it.
