I don't think there have ever been any close door buttons on the
Underground.

Doesn't the Central line have them?

The Central Line does have door open buttons, actually located on the door
itself.
However, I've never had to use them.


The thing we are querying here is whether they have close buttons. I
didn't think any Underground trains had close buttons, even if they had
open buttons. But it was suggested that the Central Line did, and now
I am not sure.

The Central Line 1992 stock did have close buttons, and probably still does.
Though I'm not sure they did anything having only used the Central Line in
the central, tunnelled, section where they didn't need to be used.

I remember posters in about the mid 1990s trumpetting this feature, claiming
that it gave passengers the chance to shut out rainy weather at surface
stops. They seem to have since abandoned caring about this.

I remember reading here some time ago about incidents where a Central
Line passenger had pressed the door close button, not realising that he
was being followed by another passenger who was struck by the closing
door. Health & Safety considerations then led to the Close facility
being withdrawn. I'm not sure why passenger-operated door opening has
also been withdrawn on the Tube when it's still in operation on DLR.

On National Rail, some of the latest stock like Class 450 on SWT have
passenger-openable doors which individually close (following the usual
warning bleeps) after a certain time has elapsed, about 30 seconds I
think. This is very useful at a terminus where otherwise the doors
could be open for a long time.

The number of times I've stood behind people who just look at the doors
and seem to expect them to open as if by magic on the DLR, I can!

If the driver can be bothered he/she does have selective door closing
available, at least on 73TS and I'm sure other stocks have it too.
We're encouraged to use this once it gets cold although it's never
policed to my knowledge.

I'm not sure about that. At a terminus, boarding a train at leisure
which is not due to depart for five minutes, surrounded by all kinds of
noise and bleeping from adjacent trains, I have repeatedly had the
doors close on me with no effective warning just as I am getting on.

I don't think that's healthy and safe. Also, the amount of delay seems
to be randomised, because doors which have all been opened at roughly
the same time as the train first arrived close at very different times.

Back to the first point, the safety issue explains why close buttons
are not used (yet they are still used on NR), but doesn't explain why
the majority of Underground stock, which has open but not close
buttons, doesn't use them. Unless it's to save confusion, but they've
never cared about that before.

The delay is not randomised. The doors appear to close x seconds after
the last person moved through them either way. This is why they have
infrared sensors just inside (about knee height). The sensor also
seems to be used (in conjunction with the door's pressure sensors) to
reopen the door if someone steps through or it hits someone.

If you are being hit by the doors quite often and, for whatever reason,
can't hear the beeps the I suggest you look at the close button just
inside the train. If the red LEDs are flashing then the door is
closing - press the open button, hit the side of the door or wave your
leg/arm between the sensor and the reflector.

This seems to have been designed with safety in mind

Maybe once they were going to do that, they should have given them
two-speed motors. After 30 seconds the door could close in leisurely
fashion, taking maybe 8-10 seconds to slide across; but on the guard's
command all doors not yet fully closed would close in the normal
manner. A two-speed flashing light would provide suitable warning.

I too believe that the 450, 444 and similar trains should have a way of
clearly indicating whether the doors are closing under the guard's
command or auto-closing. Otherwise, even when the doors are
auto-closing, people have a tendency to throw themselves through the
doors when they hear the beeps, fearing the train is going to depart.
I believe the 166s provide the distinction by not beeping when
auto-closing (probably not allowed these days).

As the OP on this issue the statment above makes the point that open buttons
are to be found on the majority of Underground stock. Travelling around quite
a bit on the surface sections of the Underground, I have never seen the option
given for passengers to open doors. Forget the issue of closing the doors, if
that has to be done under official manual control, for perhaps safety reasons,
that is unfortunate. In sub zero temperatures having the doors open at each
surface station when there is no passenger movement means unnecessary
discomfort for travellers and additional energy to maintain heating levels.
So the why the hell isn't a built in feature to the stock being used?
