Quite a few stations I can think of have external escalators - that is, ones which are outdoors rather than being tucked away underground in a nice cosy station. How are leccy problems avoided?

I don't know how they manage it, but Liverpool ONE has several outdoor escalators too:  |

I expect that they are what I've heard called 'package escalators', which have the motor within the escalator itself (rather than outside it, as is the case with the heavy-duty jobs generally used on the Underground). Presumably, for 'package escalators' that are to be used outdoors, the motor is appropriately weather-proofed. Watford's shopping centre has two outdoor escalators - and they're more often working than not, even when it's raining!

There used to be an outdoor escalator in Basildon town centre. The problem was not so much with the mechanism as with it having to be shut off during extreme weather, it is difficult to prevent a build up of ice on such escalators making them unsafe to use. Most railway rolling stock relies on electric motors either for direct drive (EMU) or power transmission (DE) and the technology is there to protect them from the weather.

Out here in Hong Kong there are many outdoor escalators - given that we had almost 150mm of rain in one afternoon the other week, it's definitely possible!  |

Can't think immediately of any LU ones that go "outside", but there are plenty on the Paris Métro that come up into the street and without any canopy covering them.

Only the one left at Greenford now :-D
Two escalators at Heathrow 1,2,3 come as close as well, one winter when snowing the one going down was bringing a bit of snow down (a tiny bit!).
I wonder if there are any more...

Cant think of any on the underground but what immediately came to mind was the escalator outside Southend Victoria Station up to the shopping centre. Although partly covered now since the shopping centre was refurbished and made indoors, I remember a few years ago when it was completely outdoors.

Escalators are usually driven by a motor at one end. As long as it doesn't get flooded there shouldn't be too many problems. I would have thought corrosion would have been more of a problem.

You know what? I was sure that Sloane Square had escalators down to platform level some time back. I can't find any proof of this now. It's not quite 'outside', but many of the SSR lines are very open at the platform area. It never occurred to me that ice and corrosion would be a bigger problem than electrics. But duh! I guess that's why I asked the question  |

They did and still do at Sloane Square. I suppose you could liken their access similar to Greenford (although not on a viaduct) on a wet and windy day. Under the shelter of a canopy, but ..........

The new escalators at Custom House will be quite close to being outdoors, at least at the lower (platform) end - I can't remember what the top end is like off the top of my head. The bottom end of the escalators at Tower Gateway are a little further under cover but not by a huge distance. Not on the Underground but there are a couple of escalators like the Liverpool ones at the N1 shopping centre at Angel Islington (the place, not the OP  ). I've not been there during cold or wet weather to know how they cope though. |
