London Underground maintenance question
Discussion

MARYLEBONE STATION (UNDERGROUND): Reduced escalator service until late September 2010 due to maintenance work. Access is via fixed stairs. Use nearby Baker Street to enter tube system, especially if carrying luggage. Reported: 03/05/10 06:31 Last Updated: 03/05/10 06:32
Can someone explain to me why it takes 3-4 months to overhaul an escalator? I don't mind repairs, but why the flock do they take so long?JRM said:
Isn't something to do with them being bespoke, or some such utter nonsense.
It's odd that escalators in large shopping centres don't get turned off for months at a time for maintenance
Seem to remember seeing a tv program along these lines. I think they genrally take them apart, refurbish the parts. Re-assemble it elsewhere and test it, don't know where though, unless it's at BRE cardington. Then once it's working properly they take it apart again, and then rebuild it in situ. And then they probably retest it. It's odd that escalators in large shopping centres don't get turned off for months at a time for maintenance
I might be completely making this up though.
Bank Station down to the DLR was out of action for MONTHS, and it's a hell of a long way down the stairs via the Northern line to the DLR platform. With one fixed, they're now doing the other side!
Yes, it's annoying they take months to repair, but I'll bet they get so filled up with dirt & crap that they want to avoid more serious issues - as has been seen elsewhere on the Underground in the not too distant past.

k knows- it drives me up the fking wall.Now you have a 10 minute queue in the morning just to get to the stairs. Its f
king stupid.5 months to repair an escalator. Ludicrous
To rip out and re-new or to completely overhaul an escalator doesn't take months as the new one or bits tend to be ordered ready and just plop in to place. But if the actual structure ie the building work round the escalator shaft needs to be renew then it is a bigger job. The old kit needs to come out then the builder, electricians, plumbers etc come in and do their bit then the new system is put in. Bearing in mind the age of some of the stations they may by full of asbestos underneath as it went a bit mad when the fire occurred a while back. Also they may be changing the location, angle, width etc of the ecsalator due to new regulations which all adds to the job.
Fitting a new one in a new build is so much easier and quicker as it is pre-build and falls in as one where as old building has to be constructed in the factory then dis-assembled to be fitted, then re-assembled on site.
Hope that all makes some sense.

When they've got rid of the old escalator, there are no stairs now.. Do they just have some very long ladders to be able to access the structure, or is it ropes from the top and a steep walk?

Mixture of scaffolding, working platforms, ropes and harnesses and old fashioned ladders depending on what stage of build you are at. If you are very, very lucky, you can on the odd occasion get a cherry picker/lifting platform in but that is only usually new builds.
Cool, thankyou!

I did forget to mention the walk to the working stairs, plod down them, walk back to the location and go in the bottom option too! But as engineers, we try to avoid such a strenuous choice!
No no, I don't blame you.. Covent Garden IIRC with no Escalator and queue for the lift..
Never again.
I thought you'd get to kind of absail down the shaft where the escalator would have been, that'd be fun!
