I think you're thinking of the Waterloo & City Line. The Great Northern
is far enough away from Bank that you could avoid any particular
building if you were happy to demolish others.

The GN&C has, or at least had, a safeguarded extension route to Lothbury,
and in 1912 there was a parliamentary bill submitted (by the Metropolitan)
to extend the GN&C to there and link to the W&C, so the vaults can't be
an insuperable obstacle for either line. The link was rejected because
of property objections, true, but if it wasn't feasible then I don't
think the Met would have wasted money on a Bill.


It's possible that the extension was only possible until the Bank of England
was rebuilt in the 1930s. Their page at
http://www.bankofengland.co.uk/educa...buildings8.htm
suggested that this rebuilding included a lot of construction below ground,
though apparently offices rather than vaults. It's also possible that the
safeguarded route ended at Lothbury rather than Bank Station to avoid going
under the Bank of England, but that would be hard to reconcile with the
intention of linking up with the Waterloo and City.

In any case John, aka Basil Jet, is probably right that I misremembered and
it's the W & C for which the bank's vaults would preclude any extension
