Method Jump height needed? If fails does train work?

[Psych3Lug3r]

I'm sure someone may have asked before but what is the lowest height needed to die from a jump off a bridge or building?
If I fail and the bridge is above a train track the train is sure to kill me if the jump is unsuccessful right?

100 feet bare minimum. Keep in mind trains can stop, albeit slowly.

 

[DT2007]

It takes a train at 100 km/h almost 2 kilometers to come to a stop. So no worries, when he sees you in the tracks it'll be 2 late 2 stop

 

[antilife]

I tried both methods but survival instincts kick in hard. So I couldn't do it. SI is the only reason why I'm still alive

Would not recommend trains, as you will traumatize someone else. Also chance you won't succeed depending on how you do it.

What does surving an oncoming train depend on?

I thought 6 stories was the bare minimum?

Tbh, if one needs to consider the minimum height of the building/bridge, chances are it's not high enough to jump from and if it is indeed high enough the chance of hitting the train track on target and staying there is then again quite low.

I know there was someone who jumped one floor, a mere ten meters, at Heathrow airport head first and died, but how many of us could resist putting our hands in front? Therefore, I'd imagine it's always best to resort to actual momentum instead of minimum height.

What I've read is that ideally a fall onto land would be 150ft and a jump into water would be 250ft (GG Bridge for example). I've been trying to find info on what the true minimum lethal height is, because finding something 150ft tall without driving to a huge city seems unlikely. If anyone has found more info on this lmk.

 

[golden_triforce3]

I've read at least 10 stories, at least 150ft, at least 100 meters, etc. But I've never seen anyone explaining why or basing it in any kind of science. I can only assume it's anecdotal at best.

Wouldn't surprise me if no one actually knew. It's not like we can ethically determine it experimentally (at least not directly). I guess it could be determined statistically based on past cases, but I can't think of any incentives businesses or governments would have to fund that kind or research.
I'm sure mainstream institutions in general would rather people didn't know so they can't use it as a resource to CTB.

If anyone knows of any papers or studies, I'd love to see the references. I've been meaning to look it up, but never got around to doing it yet.

If it stops or not, if it hits you, drives over you etc. Some people lay down on the tracks and only get their legs cut off for example.

But if I just stand before it Ill die, right? I mean, its a fucking train, noway anybody can survive getting hit by an incoming train.

If it doesn't stop in time, which means you'll have to be hidden well for some time and then be able to get to the tracks and get in position without being seen. It needs to be going at quite some speed. And I know it can work, but like I said, you WILL traumatize someone, no doubt about it.

Hm, okay. Any other advice, that you have?

yeah, don't choose train as a method.

Highly unlikely, yes, but if you flinch you might or perhaps the situation requires you to jump in front spontaneously which is another possible cause for failure if hitting the wrong part. Also depends on the speed, of course. Personally, I'd prefer a decapitation, but most trains have cowcatchers in front, something to consider as well.

 

[Mäximum]

A hit by a train which is 210 km/h {~130.49 mph} fast and weights 417 tons would create around 202.7 meganewton, which is quite a lot.

For reference:
Falling from a 100 meter {~328 feet} as a 90 kg heavy human would create only around 5.69 kilonewton.

Please consider that these are only estimations. Because I did the calculations myself, there could be mistakes. Calculate them yourself if you want to be sure.

 

[Cage]

Yeah getting hit by a train doesn't sound like a great idea to me; I imagine if you get sucked under the train it'll take a few extra moments to fall unconscious and die, meaning you'll be in extreme pain for at least a few seconds.

If you jump from a high enough height though, you'll probably die immediately, which is a much more comforting thought.

 

[Psych3Lug3r]

Do appreciate all the advice and am taking it into consideration as this is still a method I'm considering as it's one I feel I could get away with where I am
Sadly hard to measure and know for sure the right jump distance

 

[silentcicada]

It's very easy to survive falling so please be careful. Always go head first. It seems like the general consensus is you shouldn't go lower than 100ft.

 

[oneeyed]

As for falling, you can die even tripping over your own feet, hitting your head. So the height is so you gain enough velocity for maximum force. According to a quick google search, terminal velocity is 200 km/hr (120 mph) and is reach from falling 450 m (1500 ft). So higher is "better" but your landing will determine if you die and how quick. SI is a bitch though.
