MISC | Train door opening

The different door operation mechananisms of the world's subways/metros are pretty interesting.

Please let me know which door mechanism your subway city has, or which you remember from your travels. I would like to make a list and publish it on the Internet. Unfortunately I can't remember the door mechanisms of all the subways I've seen.


I tried to figure out the possibilities and marked them with letters:

OPENING:
A: all doors open automatically
(in sync, operated by the staff)
B: button or lever operated
(after passenger operates button/lever, door slides open automatically)
C: motion detectors
(when passenger steps in front of door, it opens automatically)
D: manual force
(passenger must slide door open with his/her own muscles)
E: A in underground stations, B in open-air stations
F: A in underground stations, C in open-air stations

CLOSING:
L: all doors in sync
(after some kind of warning sounds or lights)
M: each door individually closes automatically after a few seconds
(secured by photo sensors or sensitive door edges; Open button is out of action when train is ready to depart)
N: L with optional prior closing by passenger
(e.g. by pressing a Close button)


I'll start the list with a few which I think I can remember:

Berlin: BL
Bochum: CM
Hamburg: BN, DN
Hanover: EM
Glasgow: AL
London: AL
Munich: BL
Paris: BL

Most American subways: AL
German metro trams (Frankfurt, Düsseldorf, Dortmund, Essen, Stuttgart): BM
Japanese metros: AL
Russion metros: AL
Metros with platform edge doors: AL


List update:

Barcelona: AL, BL
Buenos Aires: DL (line A), AL
Edmonton LRT: BM
Hong Kong MTR & KCR : AL
Libon: AL
Madrid: AL (lines 6,10,12), BL (lines 1,2,3,4,5)
Mexico City: AL
Milan: AL
San Diego LRT - AL, BM
Singapore: AL
Toronto: AL
Vancouver: AL

Isn't that equivalent to M?

I assume in case M that the Open button is not working when train is ready to depart.

(I'll update the 1st post)

They have buttons but the doors open automatically (the buttons seem to be a kind of decoration only )

No. Doors open & close automatically after like say 10 seconds at station A, and perhaps 20 seconds at station D. This is determined by a central computer which pre programmes the trains... There is no opening and closing done by the train operator or the passengers.

So if a crowd wants to enter the train, the doors simply slam shut and people have to stay outside even if there's enough space in the train?

Yes. But there ain't usually such a big crowd to speak of. Whatever crowd there is usually manages to get through the doors before they close. And before they close, in train audio announcements as well as flashing lights on the platform screen doors and above the train doors signal passengers to keep clear of the doors.

Even if a passenger gets caught in between the train doors, the doors open slightly about perhaps 10cm in both ways to allow the caught object/passenger to get clear before the doors fully close again.

Oh I read your question wrongly. Such cases usually wont happen because the opening and closing times of the train doors are usually enough for all to get in or out. At certain times of the day and times of the year when passenger traffic is higher at some stations, and also at major interchanges, the timings are adjusted such that doors remain open much longer.

Then I would say it belongs to case L and is just a detail of operation. All doors close in sync, and for the passengers it doesn't matter whether the staff or the computer operates the doors.

But thanks for describing the details, it's very interesting.

At first I wanted to create an additional case "all doors close in sync (doors have sensors)" but I think it is not always easy to tell if doors have sensors or not (at least in other cities than Singapore).

That is also the case for a number of US systems.

In Milan is: AL

But they installed on new revamped trains with air-con buttons to open every door singularly (that's to better preserve air-con climate inside the train: if it is not necessary to open all the doors...)

Actually, in London ALL doors are opened at stations by the driver, and closed by him/her too.

Some trains have passenger operated buttons but they are not used - and indeed a train driver can even be disciplined for letting passengers use them.

Why? who knows - for sure the passengers have not been told.

This annoys passengers at open air stations in the winter when all the doors are open and the trains are freezing cold.

Regarding door closing maybe a category should be included for systems where there are warnings before the doors close? (and the types of warning).

I was in Berlin last week and noticed how the trains (and trams) have both red warning lights which illuminate / flash and audible alarms which sound before the doors close.

This is on all of their trains and trams - even trains originally built for use in just West Berlin but now used city-wide.

It seems to be something which was policy in the old East Berlin (indeed East Germany) as when I was last there (in 1990) the West Berlin trains did not have the red warning lights. (no trams in West Berlin)

Also, I noticed how some trains (I did not check out every type of rolling stock) also have "door close" buttons, so that passengers can close the doors if they want to.

Take a look here for warnings and announcements in many of the world's metros: http://mic-ro.com/metro/announcements.html

Vancouver: AL
But when the Expo Line first opened, it was BL.
They removed the buttons sometime after it opened - probably be cause people didn't know they had to touch the button (or maybe too many buttons broke).

For opening: Some lines A (Lines 6, 10 or 12, for example) and other B (1,2,3,4 and 5). Most trains are equiped with B system but are operated in A way

For closing: All L
