Thanks. That shows the arrangement very well.

While I was there....
I found this:

http://planningonline.camden.gov.uk/...df&pageCount=6

Its an eccentric plan they made, before there was the idea of the
northern or western ticket halls, to link all the deep level lines up
directly with the metropolitan line.

What it illustrates very well, is how the platforms and lines relate
to each other, and it even has the rail link to the piccadilly lines
from the southbound northern line at Euston.

It also shows the position of the old northern line lift and emergency
stairs (the two circles between the platforms).

What's most made clear is that the "round thing" on the surface is in
the wrong place for the original picadilly line lifts - they were
roughly where the hotel curve crosses the sw-bound victoria line. As I
mentioned before there were three parallel tunnels leading between the
platforms and the lift, two from the headwalls (or thereabouts) for
exiting the station, and one longer one for those entering - the
remains of the latter can be seen in the diagram to the left of the
current picadilly concourse just where the proposed passage from the
met joins it.
