I doubt that platform doors will be fitted. There might be passive
provision
but doors on just 2 Northern Line stations doesn't look likely to me.

I always thought they were an expensive white elephant that served little
purpose but TfL seems to like them - they're going in on crossrail - so I
wouldn't put it past them to install just on 2 stations.

I don't know how useful they are, either. They do keep the track very
clean. The track at London Bridge looks almost like new.

That'll be because, in railway terms, it is :-)

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.

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

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Assuming the glass hasn't all fallen out by then and been replaced by brick.

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.

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

I think the PEDs are operated by the signalling system.

Just a thought... one of the Northern platforms at London Bridge is as
new as the Jubilee extension but doesn't have PEDs. Although perhaps
that is because the existing tunnels could be used for ventilation, so
adding PEDs would not have saved anything.

The ventilation there is partly via the old C&SLR tunnels, but also the
original lift shaft. I've always wondered if that has survived the
recent large amount of rebuilding at ground level (it's outside the
footprint of the NR station).

The old CSLR station building was demolished within the last few years
However there is now a small free-standing steel rotunda composed
of ventilation grills, as near as I can tell exactly above the lift
shaft (corner of London Bridge Street and the former Railway Approach,
immediately adjacent to the new viaduct span at Borough Market).
