If the teething troubles they had with the JLE were correctly reported,

Its ATO.
What is, JLE or the Battersea extension?
Both now, but not the Jubilee when the JLE with its PEDs first opened.
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.
If ATO doesn't know where the train is, just as well as that sort of NFC
device, I'm astonished.
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.
