That train will just keep coming. Once such a freight train is going you better get out of the way. The amount of kinetic energy that’s coming towards you is dwarfing compared to a measly tank.
A train of 8000 tons at a velocity of 30 km/h roughly has the kinetic energy of 66.39 kg TNT.
It seems to be a lot, how does it compare to an artillery shell? The tank doesn’t look like it fared too badly.
Artillery shell with 1 kg of TNT has explosion energy of about 1 kg of TNT
Do they actually use TNT as the explosive though? I thought TNT was just the igniter for something more powerful like C4 or something.
I don’t think TNT is used at all, I’m pretty sure it’s some explosive compound, as you said. However, explosives are still measured in terms of TNT, called Net Explosive Weight (NEW).
For example, one pound of C4 has a NEW of about 1.25 pounds.
Looks like it’s something like 6-12kg of net explosive content so if that’s the same as NEW then it seems that the train has it beat by a fair margin, though I doubt the trains impact is as tightly targeted.
I don’t think your units make sense — kinetic energy has units of energy, but “kg TNT per second” is power (about 4MW). (I think just remove the “every second” and it’s correct?)Edit: parent edited comment.
You’re right, but “every second” was meant more as a display of the energy in the train, like a large explosion “every second”. Is that very wrong?
Hmmm, I’m not sure I understand…
A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That’s certainly not the case — it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.
But that’s just my interpretation.
Yeah, I forgot that a large part of the energy is in inertia and not the pulling of the engine.
Sorry for Reddit watermark… couldn’t quickly find it elsewhere.
For your consideration, the Calvin and Hobbes Search Engine: https://michaelyingling.com/random/calvin_and_hobbes/
Edit to show example search for “freight train”: https://michaelyingling.com/random/calvin_and_hobbes/search.php?phrase=freight+train
I didn’t make this site, I just find it to be very useful for this extremely niche use case 🤣 Although, weirdly, it seems to be linking the wrong strip for this particular one. Dunno why, I’ve never seen it do that before.
that is literally the worst watermark I’ve ever seen in my entire time on the internet, more than a quarter century now.
Why is there a Reddit watermark at all!? They didn’t create the content, and I doubt Mr. Watterson would want it to be hosted there. Did a redditor go out of their way to slap that over the last panel? Like you said, the absolute worst…
I made this.jpg
You’ve obviously not seen some of the footage coming out of Ukraine war. They watermark over the entire video
don’t you know how much bank CNN made out of the gulf war? gotta protect the copyrights of war footage
this sub doesn’t exist on Lemmy :(
i miss r/bitchimatrainSounds like it’s time to create it!
Be the change you want to see in the world! Don’t let your dreams be dreams!
Yeah, but if you’re gonna create it, you have to post to it like once a week or it’ll just sit there dead, forever.
And who wants to find something to post once a week? Can’t I just have Facebook feed it to me. Picture Zuck saying “here comes the plane!”
Eh, if you spam it enough places, you probably only need to do it for a couple months until other people get involved.
South Carolina in September. Low-slung trailer got stuck at the crossing and the driver skedaddled right before the impact. Also, ever so sadly, it doesn’t officially count as a tank, only self-propelled artillery.
I expected more damage on the train. It really didn’t give a fuck.
I think less and less damage to either side as armor and structural integrity increase is probably the norm with trains. For example non armor vehicles are turned into fun metal tangles. This 30 ton “lightly” armored vehicle looks pretty intact. A 70 ton tank might just remain more intact as the train shunts it to the side. The train might take more superstructure damage but there’s a lot of just solid metal pushing in one direction. So I don’t think any impact like that is ever going to actually just destroy the train.
The armor is light, the vehicle isn’t.
On the other hand, a pair of locomotives can easily be over 400 tons, and that’s not counting the rest of the train. Those doublestacked shipping containers on a well car can add 100 tons each.
I was wondering how a tank ended up on a railway track.
It was training for battle.
Kinda looks like an M1A1 Abrams to me
That is 100 percent a pally. Abrams don’t have rear doors.
Nah, it’s got that extra flat butt and long overhang with the basket thing on the back of the turret. The news report also said it’s a Paladin, though this video is also showing off midsize-market local American news, so I wouldn’t have trusted it on its own.
Why don’t we use trains on battlefields? (I see no issues with this plan)
Russia and Ukraine do
You could even wrap the tracks around the train so it can go wherever it wants!
That’s just a tank with extra steps
No there are no steps. And even if there were the wraparound tracks would be able to go up them due to their circular nature.
Make a lengthier tank? Like a centipede!!
Cereal is actually a kind of soup.
And tanks are technically a type of train.
A small train that carries its tracks with it wherever it goes?
A better question is whether a self-propelled artillery “train” is a tank.
Who wants a pretzel?
And for the audio afficianado: [Well There‘s Your Problem] Episode 67: Armored Trains #wellTheresYourProblem
For those who like podcasts but want to ensure they get the right format for the podcast, go for the video version. Pure audio is fine and all but you don’t get to see the slides or Justin’s terrible scribblings overtop of the slides.
This podcast however is one where you can easily have the video playing while you do other things, glancing occasionally when they shift to a new slide or start drawing diagrams on the slides
We ironed up the boats too, steam engine warfare was kinda cool ngl
Considering tanks are transported by train, not surprising. Train big.
And the train I am currently on was transported by truck.
Your train small.
Yeah, it’s pretty small. That’s why we have to put new trains on trucks instead of just driving them from the factory. They don’t fit normal railways.
Well that’s an M109 Paladin. It weighs about half as much as an actual tank. But if it was fully loaded there’s a pretty good chance nobody wins because it’s an artillery system and it carries a lot of stuff that goes boom.
I don’t care to speculate on who wins between a 70 ton tank and a train. It probably depends on what the train is pulling.
Edit to add - also we need pictures from different angles. From this angle it looks like the Paladin might have simply been de-tracked. But I’m pretty sure there’s more damage as it’s armor is actually comparatively light, rated for small arms and shrapnel.
So it’s more self-propelled artillery?
Technically yeah, colloquially no sane person would judge another for calling such a thing a tank
It’s only a tank if it comes from the Tankeshire region of England, otherwise it’s just sparkling armoured vehicle.
Nah, I don’t judge people for being wrong or inaccurate, particularly when the colloquial use of a term is as firmly established. Ideally, people would still know the distinction, and I’d prefer to have journalists be accurate at least, but mostly I care about knowing what’s technically correct myself. I don’t need to be a pedant, I just don’t want to be ignorant.
That’s exactly what it is.
🇺🇸This is America🇺🇸
Attention dispatch… There has been a mass shooting at the site of the Tank Train collision, but thankfully all victims have successfully had their medical claims for woundcare denied. Time to go home…
Top Gun theme blares as the Police Mustang drives off into the sunset. And… scene.
Worthy of a South Park bit
This is for sure gta
Isn’t that a self-propelled artillery piece? I wanna say like an M109 or something

tank looks like missing parts of the bottom part, train is uhh 🥭
Just skirts and detracted, the hull is probably intact but likely cracked enough it will need refurb at the factory. Also it probably fell off the train rather than ran into it.
It looks like the tank returned fire.

Lookin’ like a new Transformers.
