Really impressive graphic design of this legendary beast.

considering my pixelated blob of ten years ago, i'd like to think i've improved somewhat XD

"we'll put it with our bell that's too big to ring, our cannon that's too big to fire, and the Tsar Bomba which nobody laughs at"

it's one big boi.. just don't take it round corners, otherwise it'll make them into straights.
great work

This right here is a textbook example of "Just because you can, doesn't mean you should."

yep! And it's REAL! the Russians actually built this monster!

Leave it to the Soviets to build something impractically large!

And it most certainly was impractical: it was literally too heavy for the slipshod Soviet track, demolished switch tracks it went over, pulled couplers off carriages and wagons, and was too long to take curves.

It wasn't too heavy. The goal of the design was to provide enough tractive effort on a limited possibilities of Soviet rail system.
It index is "AA20", where 20 meant twenty tons-force of axle load per driving axle. This is actually a really small axle load - equal to FD class and not that large compared to 1912 E class (16.5...17 tons-force). It allowedΒ (theoretically of course) AA20 to be operated on pretty much any railroad in USSR. "Too heavy" actually means nothing for railroad, it is only axle load that matters.
This is actually the reason of why it has 7 driving axles. Here's an answer for anyone who is interested.
Firstly, tractive force requires adhesive weight to make sure wheels don't slip with a large train behind a tender. Secondly, large tractive force requires powerful and heavy boiler. So in order to reduce axle load and make it operable on weak soviet railroad systems, designer increased number of axles. At first, AA class was meant to be 2-12-2 or 4-12-2. Then they added additional axle effectively reducing axle load to 20 tons.
Can't disagree about switch tracks, AA20 definitely had problems with passing them undamaged. However, this locomotive made it all the way from Lugansk to Moscow with 4500 ton train behind a tender.

What was the point of that thing?!

To transport something huge, no doubt.
Unfortunately, whoever designed the bloody thing didn't take into account that the tracks may not handle the size of it.

Or, just as, if not more likely, just because they could.

well, this was the era of Giant locomotives and Railway technology.

Again, just because they could.

They say "We can!", and never ask "Should we?", or "Is this really a good idea?"
π: 0 β©: 1
Yep.
Either that, or Stalin really needed that train to be built.

And what Stalin wants, he gets.

If not, then straight to gulag for you, cyka.

When in doubt, copy a successful design and hope it-
oh it didnβt work
