I meant the central line rather than the circle line - where the
escalators are now is where you have marked "offices" on your plan, but
on a 1980s photo - http://gallery120232.fotopic.net/c483527.html -
there is a road there, rather than a building for "offices".
So I was wondering how you got to the central line, as there doesnt
seem to be any way to go in, or did everyone have to go via broad
street?
