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

The safety benefits are considerable and they may well improve dwell times.

Also improved air flow and cooling.

Yes, I think those are the normally cited 'official' reasons'.

PEDs are deemed essential for driverless trains, but I don't think the
Northern line is due to get those for many years.

I fail to see how - they're only 7 foot high. If the train was completely
sealed off from the platform the sure, but it isn't. Any train heat just
wafts up and over.

I'm sure you've been told before that they reduce the need for
ventilation shafts and so reduce the cost of a new station.

How would they reduce the need for ventilation shafts? They're not
floor to ceiling.

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.
