Does a week go by anymore when there isn't a serious train failure on it?
And I think we all know which type of train.

Rather like on Saturday morning when a signal failure suspended the
line between Walthamstow Central and Seven Sisters..., just as the
replacement buses for the Central Line engineering works were bringing
extra passengers to Walthamstow....

You couldn't make it up.

It always makes me laugh when they quote "signal failure" on an ATO worked
line. It seems to be a catch all excuse for any cock up.

Signal*ing* failure, perhaps? They still have to know where the trains
are, and send them instructions, even if there aren't any little red and
green lights by the trackside.

Quite. That's what "signal failure" is used to mean on the
Underground.

Except they're usually quite specific about where - "signal failure at
tottenham hale" and so forth.

And even if the signals have failed in one small area I see no reason why
the trains can't be driven manually for a short distance while being
monitored by the line controller. A somewhat better solution that just
closing an entire section of the line.

It isn't quite as simple as that. If the normal "signalling" system
fails, the system defaults to the next level of safety - manual
driving at 10mph. This is all very well but if every train has to
pass through an area where the signalling isn't responding normally at
this speed, the numbers of passengers waiting at stations quickly gets
to dangerous, even life-threatening levels. The only safe way of
dealing with this is to close parts of the line.

I'm afraid the existing lines in London can't cope with the number of
people who want to travel. It will get a little easier when Crossrail
opens but we desperately need a new South-west to North-east line
(Chelsea-Hackney). It should have been built 10 years ago but at
£300million a mile, the government didn't and still doesn't have the
money for it.

But if its only a small section of signalling thats failed it shouldn't
make too much of a difference going at 10mph. And station staff can always
close entrances to limit the number of people on a platform as is done all the
time at victoria anyway. And its not as if the passengers all just go home,
the overcrowding will just move elsewhere - buses, mainline stations etc.
I just get the feeling that LU always takes the easy option.

I'm not sure chelsea really needs a whole new line given the close proximity
of a lot of tube stations down there already, but the hackney area could
do with one. A branch off the current victoria line from KX would probably
cover it.

The Crossrail 2 line won't just serve Chelsea and Hackney. It's had
various versions over the years, but this is what Wikipedia currently
says: http://en.wikipedia.org/wiki/Chelsea...93Hackney_line

As you can see, it's intended to relieve pressure on the District and
Central lines (by taking over over one each of their branches) as well
as providing a new high capacity diagnal line through central London,
which will take some of the current Victoria and Picc traffic (which, as
you you know already overloads the lines in question).

I've experienced some serious delays in the last few months of more than 30
mins and it's rare I don't get at least 3 delays of at least 10 mins each
week (of course rarely long enough for me to claim a CCR). On at least 2
occasions it took over an hour to get from Tottenham Hale to Seven Sisters,
typically stopping after leaving TH so I couldn't get off and "seek an
alternative route"

Tonight was very bad and at the time there were no reports of delays - a 5
min gap between Northbound trains, Arsenal playing at home ( very rude
fans ) - as I got off at Blackhorse Rd I heard some announcement about an
earlier defective train. The effect of the Arsenal game seemed to be
particuarly bad tonight and no-one seemed to want to move to the Piccadilly
line as was being suggested by LU staff

I try and avoid the new trains where possible, as 9 times out of 10 when
I've been on one it's either broken down or waited for at least 3 mins
between each station. Being more regular now, it's getting hard to avoid
them though. I've therefore taken to an alternative route in the morning
that means as little Victoria Line as possible (or potentially none at all)
and means I get to work on time and has potentially saved me my job!
