Just curious - does anyone know what form the architecture will take, will it
be like the JLE, crossrail or something completely new?

Both stations will be under large new buildings, so they may not have
much surface presence. I think the inside design will be similar to
Crossrail, as that's the current style. The JLE stations were designed
20 years ago.

Ah, the Bland Glass Box style. Oh well, so much for innovation. In 40 years
time it'll look as dated and unattractive as 60s tower blocks do today.
Assuming the glass hasn't all fallen out by then and been replaced by brick.

Also I presume the 2
new stations will have platform doors too which I imagine will mean some new
kit on the trains - unless its already installed.

I don't think there will be PEDs. But why would the trains need extra
kit if PEDs are fitted?

I just assumed there needs to be some kit in the train to tell the door
mechanism that its arrived and fully stopped. I can't see how you'd get the
2nd part of that accurate enough just by using some sort of passive sensor.

If the teething troubles they had with the JLE were correctly reported,
most of the PED-synching is down to the driver's skills, rather than
technology.

Its ATO. However there still needs to be something to tell the platform doors
to open when the train doors open and I assume its some bit of NFC kit on the
train.

What is, JLE or the Battersea extension?

If ATO doesn't know where the train is, just as well as that sort of NFC
device, I'm astonished.

Both now, but not the Jubilee when the JLE with its PEDs first opened.

I think it's the signalling that operates the doors, and of course it knows
exactly where the train is. But I'm not sure how it knows to close the
PEDs.

Or open them given that its still down to the driver to press the open button
AFAIK. I doubt a signal is sent all the way to the main signalling control
system then all the way back to the doors to tell them to open because if the
train is being driven in emergency manual mode because of an ATO failure then
those platform doors won't be opening anytime soon.

Presumably the signalling system knows the train has stopped in the right
place to open the doors. Perhaps the on-board ATO also tells the signalling
system if the doors are open/closed, while the signalling controls whether
the doors can open? There's presumably a manual override for emergencies.

The Jubilee is ATO now, but wasn't when the JLE opened.

I think the PEDs are operated by the signalling system.
