If the Bank of England sacrificed its vaults (Very little use for them
now, with the gold sold off) and Cannon Street St was put underground
(Plus a new tunnel under the Thames), would a tunnel connecting
Moorgate and London Bridge be feasible? Or do the tube lines around
there make it impossible?

This is highly speculative and I'm sure the engineering feats involved
would be considerable, but how about connecting the Northern City / WAGN
line with the Thameslink spur into Moorgate, and restoring the 3rd curve at
Farringdon Junction making it a triangular junction again. Would create
more direct North-South journey possibilities without building a second
tunnel. However after Thameslink 2000 is complete this might prove rather
superfluous anyway as there will be a direct route from the ECML through the
new Kings Cross Thameslink station and on to Farringdon. It seems a shame
to abandon the Moorgate Thameslink route though.

Who says it has to be abandoned?

If Farringdon Junction does need to be lifted and replaced with plain
track in order to extend the platforms, what's to stop the third leg
of the Thameslink Triangle, from City Thameslink to Barbican, from
being restored in response?

This way, the old Ludgate Hill/Holborn Viaduct scenario is recreated:
Thameslink gets the through route to Midland Road, as well as the
alternate terminus at Moorgate if things go up the wall; anybody who
wants to go to Moorgate from Midland Road can use the Met from
Farringdon.

Has this ever been proposed? If it hasn't, how could something so
obvious be missed? Is there anything preventing the third side of the
triangle from being restored?
