Given the sensitivity of the Victoria Line service to dwell times, will the door engines on the 2009TS be powerful enough to shut the doors as fast as possible when the driver hits the button?
I can understand if the "wick" is turned down to prevent the doors from breaking someone's arm or pinching their clothing, but given the 1967TS's glacial door closure pace, anything would be an improvement IMO.

Door speed aside, there will apparently be 3 secs warning before the doors start to close which may lengthen the door closing time, but may or may not decrease the chance of the doors being obstructed.
The door pressure or torque would probably be limited by the HSE, but should still allow for pretty fast door closing. The sensors in the door may be quite sensitive though, which may increase the number of door reopenings.
The doors will open automatically at stations which may save a second or two.

Automatic door opening? Interesting...
Presumably a full set of door controls will be provided, including a cut-out for this feature - I doubt that anyone wants it to be enabled all the time...

another thing less for the Vic Line button pushers then! Just close the doors and press the button.

The doors IMHO should close with some speed, but we must warn the people otherwise there will have to be a TFL hospital. Door injuries, third floor, crushed ribs from faregates? Fifth floor... ;D

Door speed aside, there will apparently be 3 secs warning before the doors start to close which may lengthen the door closing time Putting aside RVAR for the moment, there are two arguments here: 1. If there are 16 stations on the Vic. Line a 3s warning for each adds 48s to the run time. This increases the journey time for all the line's users. 2. If there was no warning, there would be more door obstruction and some dwells would have to have a door re-cycling time added (5.5s) plus the new pax boarding (1-2s). You would only need that to happen at 6 stations to equal the door alarm time. Are you sure about that. I cannot see that happening. I also think automatic door recycling is not going to happen. Can someone confirm these please? |

The doors will open automatically at stations which may save a second or two. Ooooh ! Not so sure if HSE will like that. I certainly don't. [Thinks of the problems] As for sensitve doors edges or whatever. That is just asking for trouble ennit? The pax will have fun making the doors pop back and forth like a stick insects mandibles won't they? Especially when kids clock the idea and decide to play 'mind the doors dude' Also the door holders will have a field day when a young buck see's a nice bit 'o skirt hurrying for the train and wants to let her in to ogle her. Or what if an item of clothing or an umbrella spikes gets caught in the doors. They 'll be opening and closing till merry England comes again. Baaaaaddd ideas! I have to agree. As I was reading through the thread I was thinking pretty much everything that Hindenburg wrote. |

Automatic door opening is used on many metro systems around the world with few problems. I can't quite see the safety issue? (Which you didn't seem to elaborate on). In fact many metro systems, both driverless (e.g Paris Line 14, Singapore NE Line, plus the many VAL systems) and with drivers/operators (e.g Hong Kong, BART, Sao Paulo) have automatric door closing. However, automatic door closing is not without it's problems as the doors have to be more sensitive to minor obstructions which can increase the number of door reopenings. |

I am going to start a new thread on doors for both the 09ts and 'S' very soon. I know you guys want some info and I have been unable to give it so far, but that will change shortly.
What I can say is that StephenK is exactly right, we will be seeing automatic door opening (in ATO only) and there will be a facility to override this if required.

I've heard that 96TS will have auto door opening with the ATO,don't know if it's just PED stations or the whole line.

Won't automatic door opening increase dwell times, judging from how I see District/H&C drivers doing their stuff. ;D
Hope the doors close as fast and consistantly as the 95/96TS! At least it's prevented me from even making a try for it when I heard the warning!

A lot of drivers open the doors just as the train is coming to a stop rather than waiting that extra second or two for it to be secure. The doors can be opened at speeds up to 7mph. |

One problem with automatic door opening would be closed stations. With the current ATO system, trains non-stopping stations actually do stop then restart straight away. I assume something would be done to prevent doors opening automatically in this case?

Not too sure about the 09ts - but we won't have CSDE in it's current form with the S stock.

Yeah, isn't CSDE handled on the Central by the PAC beacons? I recall reading that PAC beacons would also be used on the Jubilee, and that they would include the CSDE functionality.
Needs more BAET...

CSDE no longer exists on 09ts and 'S', they both have the same system though.
The driver will be able to override the auto door opening at any time. Also, if a station is closed then the SCC will be able to put in a facility called Station Skip which will allow trains in ATO to non stop (naturally knocking out the auto door opening too).
