On the Jubilee line how are the platform screen doors operate when a train comes?

Train enters station... stops... light in cab lights up when stopped accruately... Driver presses doors open buttons, train borne computer interfaces with the Platform Edge Door Controller and generates an open command... all this takes place within 1.2 seconds...

Well, I suppose they managed to conjure up a 7th car, plus 4 extra trains!

The doors close at roughly the same time. Once the driver gets the doors closed signal, then s/he can depart.

Yes, the PEDs (platform edge doors) usually shut just before the train doors do, as it lowers the chances of someone making a last dash for the train doors, as the PEDs are shutting as the doors closing chime goes off.
The downside to them is that the driver only has to go past the set point a centimetre or two and they're going to have some pretty unhappy passengers... The upside is, they are doing what they are there to be doing.

PEDs are very important. They make a tube more modern looking, more safe and more clean. Problem is, it costs an arm and a leg.

AND it is impossible to make any significant change to the general design of the rolling stock: the doors have to be in the same place. |

There is already a thread about PEDS folks!

Ahh what are the PEDS working to open the doors? Are they openeing via electric motors?
What happens when the PED fails to open but the train doors open? Is that what the little green lever is for on the trackside of the doors?

When PEDS fail to open you can use the emergency green handles to manually open the PEDS

Aye, but I think the PED system will auto-generate a close command after 15 seconds...
Please correct me if I am wrong, Tubeboy...

When PEDS fail to open you can use the emergency green handles to manually open the PEDS On the platform side of the drivers PED door (which is controlled manually by the driver, with switches on the trackside of the door) there is a RKL Key hole, there the driver can insert and turn his key, which opens all of the PEDS. The down side to this of course is that the train has to be shut down... if a driver enters a platform and the PEDS or PEDS and trains doors fail to open the process is as follows: Driver overrides CSDE by selecting emergency mode, driver opens cab door and drivers PED door, driver steps onto platform and opens RIGHT SIDE train doors using back panel, driver shuts down train and removes RKL key, driver inserts RKL key into PED door control, driver opens all platform PEDS, driver yells stand clear (no pa as train shut down), driver closes PEDS, driver closes drivers PED and cab doors, driver opens up train, driver closes train doors, driver puts CSDE back to normal, and departs. As you can imagine... it is not a quick process and for a new driver who has not done it before, it is very very nerve wracking. The key hole to open the PEDS manually is very badly designed and it is sometimes hard to insert the RKL key, hence all Jubilee train ops have been issued a new-design RKL key that fits is smaller and fits in easier. Of course if it is an ongoing failure a SA will be on the platform stood at the drivers PED door controlling the platform doors for each train, so driver just does train doors. Hope this helps. Aye, but I think the PED system will auto-generate a close command after 15 seconds... The PEDS are designed in such a way that if you do not get a PSI (platform status indicator) illuminated (this is the equivalent of a pilot light, but for the PEDS) then the train will not get a Pilot Light, therefor can not move. But you can simply press the override button and it overrides the PEDS, and providing all the train doors are closed you will get a pilot light and can depart with the PEDS open. However, when the train is something like 1/3rd out of the platform PEDS close automatically. Also there is a clever system, where if someone blocks a PED from closing (ie foot in door) after a few seconds the platform PA will automatically start booming out "DO NOT OBSTRUCT THE DOORS STAND CLEAR" quite loudly  great idea! |

No PSI then do not press PDI (platform door interlock) For you to do this you must recieve the right from a supervisor on the platform so he can confirm PEDS are closed or you could be looking at a CDI.Peds are great however as one of my collegues found out that when a PEA is activated at a PED station when you are departing it is a pain to get into the car and reset during rush hour when the doors are not lining up.Remember you are still in station limits!!!

Once last year, they failed to open on a train i was on. I can't remember the station, but it took at least 10/15 seconds and they finally opened.

Probably he knew but couldn't be bothered - trust me Mitcham I've been in the same situation!!!!!!!!! I have been in the situation where I was eastbound man (on a very busy station) one night and we had a PED failure. Operation of the PCC was needed. When I got to the cab there was an I/O and trainee, and the I/O was grinning at me with the RKL220 in his hand - I operated the PCC...........................  On the other side of the coin, I have met some fantastic T/Ops who are straight there with their key operating the console....if any of you are reading thank you!!!!!!! ;D |

Some T/ops seem to forget its THEIR train, and its in THEIR interest to get the train moving. Some are good though.

I am a train op and have never asked a csa to open the peds when they have failed.The only help I would lke is a PA before closing the PEDS as shouting down the platform is a pain.Southwark station is the worst as I know of 1 incident when the train op could not retrieve his key from the PCC and had to take the supervisor's key.
Hey Alex hope you are well.See you at your station soon

Hey Alex hope you are well.See you at your station soon Indeed, when I am on platforms I use my RPA to it's best use, and we had an episode where an SA's key got wedged in the PCC and all the RKL220 keys the station has (about 55) had to be replaced. All good fun............ |

great idea!
