We are discussing passenger carrying trains, not empty ones, or those

But we are all used to unstaffed passenger-carrying vehicles which
follow a vertical route. They do in general have 'platform-edge doors).

But they don't all work the same. A couple of variants I've experienced
in my travels:

Very small lift in a Paris hotel: only one door, hinged and opening
outwards. The front of the lift is open and allows passengers to "rub
past" the doors and walls on the way up. I've seen similar lifts
elsewhere.

Set of lifts in a Cairo 5* hotel. Calling the lift is done by pressing a
centrally-located button in the lobby that requests a particular floor.
You are then directed to the relevant lift when it arrives. Once inside
the lift you can't "redirect" it to any additional floors. The lift
doors also *very* fierce. Snapping shut in less than a second with a
*whoosh* that looks like it would cut your appendages off (although I
didn't see anyone caught in them). I've never seen either of these
design features anywhere else.

I think these are quite common in France, as they allow a slightly
larger lift to be fitted in a smallish shaft.

Are new paternoster lifts still allowed? They always struck me as
dangerous, though I gather that a few older ones remain in service in
the UK. Are any open to the public?

No idea about being allowed.

The only places I have encountered them is on academic sites, univ.
Birmingham library (?), one univ. Oxford engineering (?) building.

And eleven-storey one at Leicester University as I remember, if it's
still there.

But thats not the real reason.

Not sure if that last remark applies to Crossrail (which you've already
commented on) or Paris. *If the latter, what do you think is the real
reason?


Crossrail was being referred to.

As I commented upthread I believe it is because of tunnel ventilation
or something similar. I do not know what TV requirements are - they
may not be mandatory - nor what Crossrail has in this respect - but
AIUI trying to meet all combined needs of new underground tunnels
fire, smoke evac, passegner evac, environmental ventilation, etc
conditions these days means that TV is just about the only practical
way to make things work. In turn, TV leads to PEDs. I may be wrong,
but my understanding at the moment says there is no requirement PEDs
on generally horizontal[*] railways.
[*] someone mentioned lifts elsewhere

As always, Wikipedia comes to the rescue:
http://en.wikipedia.org/wiki/Paternoster#United_Kingdom

I hadn't realised that they were (and remain) more popular on the
Continent, despite being a British invention. However, I see that one
remains in operation in a building that's within walking distance for
me, but it's not open to the public, probably like the rest of the few
British survivors.

If it's the Northwick Park one, anyone can get in it. The only deterrent is
a sign.

The Birmingham University Dental School used to have one. Not been there
for decades. later I see from Wikipaedia that it was taken out of
service in 2007. It was used by students and staff when I knew it.
