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.

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!

Higher failure rate at the begining and close to the end of service

The bathtub curve is widely used in reliability engineering.
