If other stations repairs are anything to go by expect it to be out of
action
for at least 6 months. After all , LU keeps reminding us via posters etc
how these things are so complex it takes longer to repair them than it
does
NASA to ready a space shuttle for lauch and the repair time has nothing to
do
with them putting no more than a couple of bone idle halfwits on the job
who
never seem to be there whatever time of day you go past.


Oooooh look, another expert on maintaining the underground!!

Given that I'm an engineer by trade whose worked on machinary thats a *teensy*
bit complex than the glorified conveyor belts known as escalators I think I
have half a clue about how complex they are to fix - ie not very. But in good
old british tradition we keep getting spin about how they're so damn complex
it takes months to fix and so bloody forth. Bull****. They're about as simple
a bit of machinary as you can find, the REAL reason is LU and their sub
contractors couldn't organise a proverbial ****-up with less than 6 months
advanced notice.

Oh that'd be fun, wouldn't it, having contactors working between a machine
they're taking apart and one running! Grinding machines might just play
havoc with the fire alarm systems, bringing in steps and metal panels would
sure please the insurers too!

Wtf are you talking about?

Take apart escalator and shipping to factory - 1 week approx.

Refurbish and test at factory, well lets be kind and say 3 weeks.

Ship back to staton, rebuild and test - 2 weeks.

Thats 6 weeks and I've been pretty generous with the time. What exactly do they
do with the other 4.5 months out of the 6 it generally takes themn to fix these
things??

Right...Now schedule that for the 4 or so hours a night that you can
actually do the work (i.e. when the station is closed to passengers) and
add in the fact that escalators are custom built for each site,
nominally at a 30 degree angle though I believe there's one station on
the Northern Line with an incline of 23 and a bit degrees.

There's also the small matter of them needing to run for the best part
of 20 hours a day, 364 days a year and carry around 13000 passengers an
hour, unlike your average department store escalator.

HTH,

Barry

So what? Will they get vertigo if it goes over a certain inclination? And
if they're limited to nights only why do they build these massive hordings
around them and (very occasionally admittedly , don't want to stop their
tea break) work during the day??

*yawn* Big ****ing deal, heard this BS 101 times before. You could say the
same thing about the trains. But it doesn't take 6 months to fix one of them
when they go wrong does it?! And they're probably 100 times more complex.
Please stop spouting the party line , it gets very tedious.

Of course you couldn't compare the two! Trains don't get refurbished
anywhere near the general public was wander around, there's far easier
access and no fire alarms to contend with for starters. BTW, do you actually
know the turn round time for a refurbished train?

I think it would be better if LU just closed a station completely for a month
and did all the escalators there in one big lot rather than causing years of
disruption.

At the smaller, less busy, stations, I'd agree. However, closures of
stations such as Liverpool Street, Victoria, Euston and Bank would affect
too many people and affect the stations adjacent too much.

There are several escalators at 26 degrees 23 minutes (4 in 9 climb
instead of 1 in 2).

They are at Baker Street (2), Earl's Court (2), Embankment (4), Kilburn
Park (2), Liverpool Street (3), Maida Vale (2), Oxford Circus (3),
Paddington (2), and Warwick Avenue (2). Further details on my web site.

I think that's where we came in. The Tottenham Court Road
system of three escalators does not come close to a 364 day
average.

And I sure that that they were also out of action in previous
years (2001 or 2002 or both) in the run up to Christmas.
