A boy did not alight from a train that terminated at Queens Park and
was carried on to the sidings. He jumped down onto the tracks where he
was found by the driver.

A paragraph of a press release from the RMT states "The boy was going
to Kensal Green. When he found himself on the train in the sidings, he
shimmied up and out of the train squeezing past the inner car barrier
(an apparent engineering solution to stop people trying to get off the
trains in these situations) and got onto the track. He could have
killed himself as he was in close proximity to the 430 volt live
positive rail."

Are they referring to the plastic (or whatever it is) sheet that is
hooked between each car? I thought these were to prevent people in
particular the blind falling onto the tracks from the platform.

No doubt the poor driver will get a bollocking and H&S will be wringing their
hands and wettings themselves over this. I wonder if this will mean even more
moronic and slower train checks when a train terminates just to hold the
service up even more?

Weren't train checks introduced because some idiot fell out of a central
line train between carriages or something some years back? Why can't we
just let natural selection take care of itself.

That and train surfing, IIRC. However there are supposed to be inner
barriers as well to make things safer for people passing between cars via
the end doors.

The RMT seem to be suggesting that the design doesn't work for 12 year old
boys - back to the drawing board maybe?

Why 430 Volts? Do they reduce the voltage in sidings for safety
reasons?

No, that's normal (with minus 220-or-so [1] at the centre rail).

[1] someone will be along shortly with the exact nominal figure.

Isn't the reason for it something to do with smaller insulators being
required if each rail only carries part of the voltage?

That's an advantage, but the main reason quoted is to do with keeping
the power supplies separated from earth to stop corrosion of cast iron
tunnel segments. The +420 -210 arrangement facilitates monitoring of
the power supplies.

Probably makes the signalling a bit simpler too if there's no return through
the running rails. Any idea how the waterloo & city coped with tunnel
corrosion when it was 3rd rail as I presume its iron segments there too?
