I'll throw in this idea: it could be used by a future high speed

Broad Street to Glasgow! The thing is, it would only save a few miles of
tunnelling, and would make the portal arrangements more complicated, so it
probably doesn't work out worth doing.

I'm trying to think of a way to connect it to the soon-to-be-abandoned
Farringdon - Moorgate stretch of the Widened Lines. Oh, and a reason to do
so!

Bonus points for including the Aldwych branch, the Waterloo & City,
Charing Cross Jubilee, and the Kingsway tram tunnel. ;-)
