The only bit I am still confused about is really what is happening with
the network of new and existing connecting tunnels between the KX
T/Link, Vic, Picc and Northern lines. I know we have the temporary link
diverging off the old T/L to Picc line corridor. However there appear to
be additional excavations occurring at the junction with the staircase
from the Vic Line as well as something going on in the closed section of
the old tunnel *and* more excavations where the temporary tunnel arrives
on the Picc Line platforms.

My understanding is that it's staying basically the same, but all the
tunnels are being enlarged and the stairs are being replaced by
escalators. The Picc escalators appear to head north from the
currently blocked off part of the Thameslink tunnel (which will be the
main tunnel) and come out in the same cross passage as the temporary
stairs.

It's the escalators that I hadn't picked up on. That certainly makes a
load of sense in the context of the closed off bit of the Thameslink -
Picc Line tunnel.
