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.

But it has to be closed to be able to extend the platform at Farringdon.
Of course, a "Grand Plan" could also include rebuilding that station to
reconfigure all the various junctions and level changes.

It does not have to be closed. The plan is to close it because,
apparently, of a RI diktat regarding level platforms. The same RI
seem perfectly happy with passengers getting off trams in Manchester
and onto the ramp of the (few remaining) profiled platforms. I have
yet to hear of a huge number of injuries as a result of this.

Note that the RI are sometimes used as an excuse by some people on
the railways now. Their "diktat" may be nothing of the sort and the
problem is dumbed down railway staff. However, note the word
"sometimes", there are examples of a stupid approach by the RI (one
of which has been highlighted in Modern Railways).

The bit of track north of the station is *very* steep, however; if not
the steepest on the national network, at least in the top 5.

It is indeed steep. However, I very much doubt if it as steep as the
ramps on the profiled platforms in manchester.

Don't worry , at the speed things are progressing I suspect it'll soon be
renamed Thameslink 3000.

More like a 120 degree turn, i think.

Think outside the box! Don't do it with a curve to the north, do with with
a curve to the south - a spiral tunnel heading down and round. Not only
does that give you the space to do it, but it spreads the height change
out over a greater distance.

And it could call at Moorgate twice, just in case you missed your stop the
first time.

If it's good enough for Monument (on the Tyne & Wear Metro), it's dashed
well good enough for Moorgate!
