I got onto a District Line train at Olympia and only one door of each carriage was open, I'd never seen that before and didn't know it was possible and it certainly saved us poor passengers from the cold whilst we sat there awaiting departure time.

Its actually "selective door close" rather than open!
All the doors need to be opened before "selective close" can be used. D Stock have had this feature from new.

Only one door open per carriage was very common in the early days of the D stock. It is a great pity it is not used now as they get very cold while standing at Upminster - also at other termini I am sure. Nothing like the arctic wind that blows through the carriages at this time of year (and weather) at Barking with all 8 doors open!!

I saw it used yesterday at B-by-B EB during service disruption. The first time so-witnessed for about 15 years. All the better given the lousy heaters on D Stock and seemingly not improved on refurb.
By the way, who remembers when they fitted one external handrail per-car to assist the mobility-impaired but failed to match these up with the doors that remained open in these circumstances?

The external handrail that was removed because idiots used to hold on to them as the train departed platforms?!!...... ...... Anyway, back to the subject in hand; selective close is used extremely frequently early in the morning and late at night on the District. Whilst it may be appreciated during the day time at termini, the cleaners also have a job to do and it'd be much much harder for them to do it with only one door open per car - impossible if we depart the station and they haven't had the opportunity to get off first! ;D ;D ;D Yes I have seen the odd cleaner use the inter car doors, but they should not be doing so - it's not a standard practice and they are not encouraged to clean trains in this way. Barking? Drivers don't necessarily know if they will be held - if I had a pound for every time I've set the selective close up, and whilst halfway through doing so the starter's gone green...... If I know I will be held at pretty much any open section station, I'll use selective close quite happily - but if I'm expecting the starter to go green at any moment, I'm not all that likely to bother.

Personally I use selective close a lot in cold weather at terminus stations - if the train sits there for 10 - 15 minutes with all the doors open it can get very cold indeed.
Some of the cleaners seem to get very confused by the selective close, but quite frankly that's their problem - don't they get trained on this stuff?

Cleaners? Why should my car be cold because of some private company that's screwing money out of TFL and no doubt playing the minimum wage (or less).
Also I know why the external handrail was removed, but what sort of idiot placed them on doors that didn't line up with the selective close option?

Some of the cleaners seem to get very confused by the selective close, but quite frankly that's their problem I think that's a poor attitude to adopt - especially given that many of them are foreigners. You are actually making their their job harder as they have go up & down each car twice just to use the only door you've left open. don't they get trained on this stuff? They are cleaners; why would they be trained on train equipment? Cleaners? Why should my car be cold because of some private company that's screwing money out of TFL and no doubt playing the minimum wage (or less). So it's the cleaners fault they are on the minimum wage and working for a company that's, according to your claim, "screwing money out of TFL"? Quite frankly, it's tough luck if you get on my train a terminus during the day time - I firmly believe that I should put the cleaners needs ahead of the customers - after all, these poor sods have to clear up the mess left behind by the very same customers; and as I said above, I'm not gonna make their job harder by forcing them to go up & down each car twice. As an aside, do you think my cab is warm when I change ends?

I've used it several times in the past few weeks at termini and sometimes when I've arrived early at a regulating point. Although I find passengers often sit in the vicinity of the one remaining open door, rather than moving down the car to feel the benefit!

Personally, if the passengers are going to put the train in a mess, they should deal with the cleaners needing all the doors open! Perhaps if the punters took their litter with them there would be less need for cleaners!
SSL Stock.
PS. I saw selective close used at Ealing Broadway on a C stock on Sunday (T117)

As an aside, do you think my cab is warm when I change ends? Trains should be cleaned in depots, see-through litter bins with slots wide enough for papers should be put on stations, free newspaper distribution should be banned. Ironically LRT kick-started the free newspaper phenomenon by allowing the 'Metro' to be given out on stations (prior to this, regular T/C entries would state that free magazines were not allowed to be given out on stations as they "cause litter" and create a "fire risk" [presumably the Metro is printed on fire-proof paper?], these paragraphs then disappeared). At least a train cab has background heaters which can be left on and a fan activated when the cab is operational, many D (and C) Stock cars seem to have no functional car heaters at all. It would have been nice had local management taken on board the company "behaviours" banged-on about in "Valuing Time" and reinstated Passenger Door Control during this coldest weather for nearly 20 years. In this case, regular PA messages on stations reminding passengers of this change would actually be of use. Not much use on the Surface Stock lines of course!

I've used it several times in the past few weeks at termini and sometimes when I've arrived early at a regulating point. Ahh, you have clearly been well trained Seth ;D ;D ;D Anyone present on my train will frequently experience Selective Door Close operation. I use it consistently in cold weather or indeed wet weather. I use it at terminal stations, open air running stations if I'm expecting a moderate delay at a red signal (or any open air red starter if it's really cold) and I use it at Barking Platform 1/2 to stop a gale removing the pathetically low heat output of D stock saloons. (Which incidentally is not a fault of D stock, it's because the depot's have turned the thermostats down, odd cars can still be found toasty warm on a train of otherwise cold cars). The matter of cleaners on trains does not detract from instructions on the use of selective door close, however I have had them complain to me about setting it up as they have to double walk each car (or use the comms doors) whilst I do feel sorry for them, at the end of the day I too take the view my passengers should not freeze in consequence. As it happens they seem quite happy to completely ignore any cleaning activity on my train when it suits them (or to demand to know if it had been cleaned at the other end of the line). I always reopen all the doors (at a terminus only) when ready to depart make the announcement and then close them all. The issue of some D stock cars being unheated (due to depots removing fuses in the summer rather than repair faulty thermostats) is known at senior levels and Metronet performance on this under scrutiny.

I used to turn the car thermomstat up on nights, before sleeping, alas later this control was sealed off!

The issue of some D stock cars being unheated (due to depots removing fuses in the summer rather than repair faulty thermostats) is known at senior levels and Metronet performance on this under scrutiny. Its been ten years since I worked on D stock, but as I recall the thermostats were very reliable. The main issue with the was the position of the sensor in the perforated silver thing above the single seats, this put them in the draft of the air from the hopper windows and this could cause the heaters to remain on under some fairly warm conditions. They were also prone to drift, but this could be adjusted. The normal reason for removing heater fuses was (and I suspect still is) due to low megger readings. Because of the arrangement of the heaters in strings finding a heater with poor insulation resistance was a real pain and could take the best part of a day to find and fix. There were some proposals to move to remove the Fan MAs add a new auxiliary supply and power the heaters from a lower voltage AC supply , as the 630V in the saloon was considered to be potentially unsafe, also the arrangement of DC resistance heaters in series strings meant that a Short circuit in one heater could cause the volatge across the others in the string to increase and hence increase the surface temperature to rise. I dont know if they did anything on refurbishment

Why have all the passenger (sorry customer) operated door buttons been disabled ? I know they have been like that for years, but this thread just reminded me that passengers had to press a button to open doors from outside and inside. That's whathappens sur le continent.

They've been tried several times,as far back as pre war,every time they've proved to be a maintenance liability.

That's what happened: in Paris metro, the new stock (MP89) used with ATO on line 14 and (until now) with a driver on line 1, have doors which open automatically at every station.

The difference is, the Paris Metro is mostly underground. The opposite is true for LU...

The C2Cs, at Barking and Upminster across the platform from the D stocks, have passenger operated doors and not only can customers operate them without any trouble, even 70+ folk like me, but they seem to be trouble free too.

I thought the reason the passenger open door buttons had been removed was to cut down on dwell time at platforms?

PDO is a thorney issue with everyone involved in trains, be it maintainence staff, drivers, line controllers, bean counters, etc. Everyone has their own unique vendetta against it; whilst it may seem a good idea in principal, in practice its said not to be. Its been discussed on here many a heated time. Though, as a passenger in the winter, I can't really see the downsides... Are thermostats in the ceiling panels a wise idea? Afterall, heat rises...seems like a fail.

I was involved with the original design of PDO, and we were determined not to repeat the failures of the past; the team succeeded. PDO was used for many years, with very few failures. Although the buttons were removed during refurbishment, most still worked despite having never been overhauled.
PDO was eliminated simply because it tended to increase dwell time at critical stations and it was too hard easily to have passenger open in the open and operator open in the tunnel - which would have solved the problem. The train was never designed to have the ability for passenger open sometimes and operator open at others. S stock will have this capability.

Especially when the t/op is slightly tardy in opening the doors. When it took about a minute before the doors were opened at Leytonstone westbound on one occasion one of the buttons took a real hammering from one impatient chap in a suit! At least it wasn't the nearly 5 minutes I had to wait to exit a HST at Swansea few days ago when the doors refused to unlock, despite having worked perfectly at every other station from Newport (and presumably from Paddington as well)

On the D stock the buttons are now blanked off but some passengers press the blanking plate.

They could just have a simple rule: open doors yourself at overground stations. Stick it over the windows at eye level to make it crystal clear. If people don't understand that then it's their own fault.
Overground stations don't have particularly long dwell times as it is, with a few exceptions where the driver could easily open them at his/her discretion.

I proudly claim to be the fella who rediscovered in the POGO switch and then found a fella with a key for it . Firstly we turned them all back to guard open and then we did the experiments on the door engines to determine the maximum opening and closing speeds that could be tolerated. This speed increase was then used as part of the justification to change out the top guides for the lovely Star Trek sounding doors with linear bearings that you have today .
