Perhaps if you trolled less, you'd have fewer potential assailants.

Quite. It must be tiresome being such a tit.

As I understand it you cannot cross the rails to another platform on the
tube except where the stations are in the open air. On the sub-surface
lines (i.e. not the tube), you can, though.



Even that is not true.

There are many open sections where that are ''line clear'' (which
means in simple terms are treated the same as tunnels) i.e. the
Jubilee all the between Stratford and Canning Town portal is one.

I think we can all wholeheartedly recommend jumping between the
platforms on that stretch (well, except the third one at Stratford).

would be across the tracks to the neighbouring platform.

What is the recommended method of crossing tracks in these situations?

There seem to be a variable number of rails making up the tracks,
usually about 5. Which of these are 'live'?

Will stepping on a live rail result in immediate death? What is the
safe distance from a live rail? Is it safe to tread on a live rail
with only one foot with the other in the air, in order to avoid
earthing the current?


Trial & error, its the only way to know for sure.

I suggest you give it a go, trying each rail in turn.

Remember to wear the proper safety gear e.g. heavy cotton or woolen clothing
soaked in Water (or lighter fluid), and heavy wet woolen socks with no boots
or shoes.

If you don't detect a tingling sensation then you might want to lie on the
track and wait for the next train to come along, the driver will see you
laying there and he'll stop, you can then knock on the cab door and ask him.

Please feel free to report your findings back to the group.

(PS - Some or all of the above statements may well be false)

I recommend the use of army ammunition boots, with metal plates fore and
aft. This gives the wearer a skating chance of making a meteoric
impression.

the running rails typically have no current going through them.


False, though it will be a relatively low current and voltage.

The rail in the middle and the outside 4th rail are the ones to watch out
for. they have -210 volts and +420 volts running through them respectively.


Approximately. They can be up to +750V in some places.

It is highly unlikely that 750V can deliver instant death. I guess
you'd need at least 50kV for that under normal conditions.

There are, however, people who have survived much higher voltages, but
many have taken lasting damage in the process.

There are also people who have been killed by 50V.

It all depends on the duration of your exposure, the impedance of the
return path and the part(s) of your body the current flows through.

5 milliamps is sufficient to permanently stop your heartbeat. So you
could theoretically kill somebody with a watch battery. You'd have to
dig the electrodes into the heart tissue first though, so that sort of
thing is unlikely to happen by accident.

On the other hand, there are people whose hands or legs have been
roast to cinders, but who survived because the current didn't get
anywhere near any vital organs.

The safest advice is, never mess with electricity.

And that is only the nominal voltage. The actual voltage may be
higher under some conditions.

Even the Americans can't electocute instantly, with 100% certainty, people
who have been sentanced to death by electric chair. That can be a slow,
painful death, requiring several attempts, before the subject dies.
