Anyway purely for my own interest I've drawn up some of these ideas,
and any constructive comments from the group would be most welcome!

See my proposals here -

The main problem seems to be that any capacity you gain by grade separating
Baker Street Jn, would be lost by the new conflicts at Moorgate, where all
terminating Mets have to cross over in front of westbound Circle/H&Cs.

Great diagram!

One comment: I initially found the Aldgate diagram hard to comprehend
not being familiar with the junction names and north not being top of
the map. Would the diagram be easier to understand if the top of the
diagram was north?

And two questions:

1. What are the benefits of the changes at Paddington?

2. Could you not also implement grade separation at Moorgate to avoid
conflicts? Eg a new tunnel connecting platform 2 to the lines to
platforms 3 and 4 at Barbican?
