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.

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).

Ah-ha! and it's got doors too :-) That probably means you can still go
down the staircase inside, to the platforms (it comes out in one of the
passages about 2/3 way from the bottom of the main escalators to the
platforms). It could even be an emergency exit from the station.

Yes, the ARP shelter entrance No.6 was apparently adjacent to 9, London
Bridge Street, but was demolished and capped with concrete during
the 1960s redevelopment of that plot. The associated foot tunnel was
retained for access to the CSLR tunnels via new connecting shafts (the
tunnel rings for these works are dated 1968).

But after 25 years, I don't remember exactly how the various old and new
works join up. I've been looking without success for any plan that might
show all the passages, not just the old tunnels. ISTR the 1960s access
steps came up inside the CSLR booking office, rather than using the lift
shaft itself. http://www.leverton.org/tunnels/cslr/csl3.jpg is taken
from the bottom of the lift shaft and shows the new steps ascending some
yards away, up to the left. Open to correction on the above as always,
and it would indeed be very interesting to know whether and how this
has been retained.
