Here's one of those 3d diagrams for Liverpool Street/Moorgate :http://www.crossrail.co.uk/80256B090053AF4C/Files/liverpoolstreet3d/$FILE/li...

The grey bits are the old station (and the even paler grey bits,
unhelpfully added, are the streets).

If you look closely though, there are bits of the 'old station(s)'
that make no sense:
-a rectangular bit west of the central line, and west of the disused
curve for the metropolitan line, at liverpool street.
There used to be a railway station there called 'broad street', but it
got demolished in the 1980s (the broadgate centre is built where it
used to be). The central line used to have a direct exit to broad
street station, and the 'rectangular bit' is the former ticket hall
for that exit; I can't remember exactly how it connected at platform
level, but there are exits at the south end of the platforms (the
westbound ends) that lead into a corridor that headed up in that
direction.

-two very thin tubes (which look too small for lift shafts), just to
the right of that rectangular bit
I'm not sure. I remember the broad street exit having an escalator (at
right angles to all the other escalators at liverpool street), so I
don't think it can have been lifts. Maybe one was for the emergency
stairs?

-a long passage below and slightly south of the main ticket hall at
moorgate, and just north of the metropolitan line (just beyond the
east end of the platforms). This passage has a curve to the south at
the western end
This joined the deeper lines with the metropolitan line, before they
rebuilt it to add the escalators. It used to connect up with the
metropolitan line underpass (that's why there's an underpass as well
as an overpass), but these days of course its hidden behind a bland
door.

-a long thin passage directly above the northern line, and parallel
with it, south of the platforms (and south of the ticket hall).
That used to be a signal box, you can see the ladder contraption thing
for it just as you arrive/leave the platforms by train. I'm not sure
if its used for anything now. Judging by all the drips coming from it
I dont think its been used for anything for years.

-a round/circular room under the steps that lead from the ticket hall
to the east side of moorgate. A long passage passes next to it, with
junctions towards it, so this may be some form of disused lift shaft,
but I thought that the northern line ticket hall had always been on
the west side of moorgate?
Yes its a lift shaft. The northern city line (now Worst Capital
Connect) originally had their own entrance on the east side of
moorgate. Britannic House (the current building on that side) was
built after they put the escalators in, and redesigned the ticket hall
to be underground. There's an airvent in the exit on that side that
feeds into the shaft.

There were passages on either side, as usual, but the passage on the
side nearest the platforms was, if I was told the truth, cut off when
they extended the line south (the extension was abandoned very
quickly, which is why the tunnel doesn't go more than a few metres
further on the platform 10 side than on the platform 9 side). Those
doors on the 'wrong side' of the tracks should therefore give access
onto what remains of the passage.

Unusually, the emergency stairs wrapped round the lift shaft, but
there's hasn't been much left of them since they built Britannic
House. I think you can still get at the remains by using the
precariously thin walkway at the end of platform 10.

-a strange short passage, with some sort of disc around the middle,
below the east end of the long passage by that circular room
That sounds very unusual so are you certain that it was definitely a
disk?
