I think they seem to think if they delay the train it'll somehow
magically be able to alleviate overcrowding further down the line when
theres a gap in the service. Trouble is , what the geniuses in the
control room don't seemed to have worked out is that a full train aint
gonna pick up any more people whether it leaves now or in 10 minutes
so they might just as well let it go on its way so at least the
passengers it already is carrying won't be delayed along with everyone
on the platforms.

Why keep an already over full train stood at the platform ? People get
stressed, LU staff get stressed, and you could tell the driver was getting
stressed.
Pointless jobsworth regulation doesn't help the public and it doesn't do
much good for LU staff.

regulation really isn't pointless - though it is not always successful and
could probably be managed much better.

While your train may be packed - and on time - the train behind may be even
more packed, meaning longer loading/unloading and so falling more behind,
thus meeting more and more full platforms and falling even more behind ...
etc.

But it would probably be better to spot the problem before five minutes
'regulation' was needed; a quiet word to the driver to dawdle by 15 seconds
at each station would be smoother and much less in-yer-face and frustrating.

An even better solution would be to run more trains - but the Picc has
another ten years before that happens - not just the extra trains, but the
signalling to go with it.

Do points often randomly move on their own when a
signals fails to red or whatever the victoria line equivalent is?


AIUI - its in the wiring of the said point/s and signal.
The "green" proves to the driver that the points are both set and LOCKED
(safe)
However with a red signal the associated points *may*
A) Be in the wrong position (being diff to the signalmans diagram)
B) WONT be locked (unsafe) and for that reason those points "could" move as
a train passes over them (remember its a failure and with no "green" there
is no proof thay are locked). Or they may even simply be set for a wrong
route.

Why would they? Do points often randomly move on their own when a
signals fails to red or whatever the victoria line equivalent is?

Often, the root cause of the signal failure is a failure of the
points locking mechanisim (or the magic that tells the signalling
system it is locked).

And yes, points do move under a moving train when the locking
mechanisim fails. It happened at Camden Town, Potters Bar, and
Grayrigg(sp?) fairly recently.

Why would you have to magic up a driver? The train already has one and
since he can't get to where he was going anyway why can't he just
drive it back in the other direction?

Actually he inadvertently has a point here - aren't the new Thameslink
trains being specced with CCTV in the driver's cab so s/he can back up
without changing ends if required...?

Fair enuff , I didn't know that. Perhaps it would be too expensive but
couldn't each set of points have a backup locking system?

Another thing is that the affected points are not always immediately in
front of the driver and could be round a bend or 300 yds further up which he
is unable to see, and one signal may be linked to a total of 3 "sets" of
points before its able to turn green and any one of the three may be the
problem. He wont know which ones are causing the problem.

All it shows is that LUL have little in the way of fall back
procedures in place when things go pear shaped. A broken door or dodgy
signal should not end up with 5 trains worth of people stuck in a
tunnel for an hour. Broken signal? Fine , drive through it on caution
and let everyone detrain.

Co-ordinating all the trains that have to move through that signal takes
time. This has knock-on effects on the rest of the line.

Whats the problem? Broken door? Reverse
train back into platform , empty pax and take it away again. Sorted.

Not safe if you don't know precisely *how* the door is broken. I
certainly wouldn't want to be on a moving train with a broken door,
because I don't know whether the door might just randomly open, or fall
off, or whatever. And if it falls off and gets tangled up in the
undercarriage, or damages some trackside equipment, then you've just
made the delays a whole lot worse.
