on http://www.abandonedstations.org.uk/...e_station.html, there
are pictures of several abandoned corridoors and passages at moorgate
which connect to the northern city line platforms. But every time I
try to piece them together, there always seems to be an important
missing detail - there are no doorways, blocked or otherwise, which
seem to actually join the northern city platforms. So what I wanted to
know was how you would have originally got into these passages from
the platforms - was there an exit at the platform headwall? and how
would it relate to the photographs (ie. where does it join up)?

another strange moorgate feature on that site is that there was a
corridoor on the "other side of the lifts" for the northern line
heading in the opposite direction, towards "the Metropolitan". Can it
really be the case that if you were going from the northern line to
the metropolitan you were supposed to wait for a lift to turn up and
then just walk through it?

The northern city line also has a long passage to the metropolitan
line. So there are two long twisty passages to the metropolitan line
from the northern and northern city lines, but neither passage is in
use. As these seem to have been at least two floors below the
metropolitan line, then presumably there must have been some sort of
stairs to bring them up to the right level; so, since they wouldn't
need lifts, is there any reason they can't bring these back into use
as they would be much needed congestion relief?

Do they perhaps come out in really awkward places on the metropolitan
line platforms? If not, could they be turned into disabled access to
the northern/northern city platforms?
