Would you jump down off the platform whe a 60-80mph Intercity 225 was about 50 seconds away and a class 321 just 20 seconds away on the other lane?
In my own mind;
Definitely not.
I may be blessed with the ability to put a lot of heavy momentum into my movements (I've been hit twice by cyclists and once by a moped each doing about 15mph, and in all cases the rider has come off worse) but pit me against a 165 or 220 at
any speed, and there would be only one possible result. It wouldn't be me walking away from that collision...
Regarding the question of saving someone; It really depends...Someone who is clearly capable of making their own decisions and calculating risks for themselves I'll leave alone and let them earn their Darwin award if they so wish.

On the other hand; In the case of someone who
isn't capable of gauging the risks and making those decisions for themselves (I.E: Children under 12, and those with profound mental disabilities) would get a quick assessment of the risks and best course of action to be taken. If that includes pulling them off the line (ONLY if an oncoming train couldn't be signalled to stop in time) then so be it.
Re: the other point raised shortly after you posted this, do all unstaffed stations have the help points now? But the same thing as with the phone really, although in this case I guess there would be enough volume for me to at least know when the call button has been answered even if I couldn't make out a word that was being said?
Some help points can be pretty hard for me to hear...And although I suspect I might have a minor hearing impairment (Twenty years of Metal and five years at Wacken'll do that to ye!

) I would imagine that those with even perfect hearing would struggle to understand what the operator is saying!

hock:
I don't know if this applies in most places, but the help points on all SWT stations have CCTV cameras aimed directly at them - Presumably to keep an eye on anyone pressing the [Emergency] button and/or let the operator see if the passenger is in danger or distress. What ye could try doing is to note the location of said cameras at stations ye visit regularly, and whenever using the help point face the camera and give clear sign language.
I don't know if ye can speak normally or not (I consider this possibility as there is a chap living in my street who's been deaf since birth, and he doesn't seem to have been able to learn the sounds that make up speech as a result) but if ye can, best thing to do might be to say something like "
Person on line at [StationName]. Warn and stop ALL trains. I cannot hear you as I am deaf." as soon as the operator picks up. If ye can't hear the operator answering the call-point, it might be best to repeat the first two sentences about 4-6 times as soon as ye've pressed the [Emergency] button.

As a final note about people trespassing on the line; I was Killing time at Waterloo on Friday night (I'd just missed the 23:48 train, and the next departure was at 01:05) and came across a rather nice poster on the side of the LuL escalator building by platform 19.
It showed a line with sleepers made out of coffin lids - The epitaphs on each noting what caused them to trespass and be run-over (The usual
Taking a short-cut and
Went to retrieve a mobile phone etc) - And it finished off with something like "
Keep off of the tracks...It's a Death sentence".
Personally, I like the ad quite a lot...But does anyone agree with me that using a photograph of a genuine one-under - Showing the full horror of the incident in a completely uncensored manner - Would be a much more effective way of getting people to stay off the lines?
