Tom Anderson:
Has consideration ever been given to connecting the W&C to anything?

"Sam":
There have been proposals at various times for extensions north, to
meet the ex-Northern City Branch at Moorgate.

Notably by the Metropolitan Railway just after they took over the latter
line in 1913.

However, these proposals always mention that the Bank of England
vaults get in the way. I think in reality, the direction of the W&C
platforms at Bank isn't particularly suited to an extension at Moorgate.

To save money, the W&C station (originally called City, not Bank)
was built with its platforms some distance west of the actual square
where the Bank is -- what's why passengers reach the surface by a long
inclined tunnel (which did not have a moving ramp until 1960) -- and as
I understand it they're under Queen Victoria Street. That would give
a reasonable alignment for an extension toward Moorgate station, if
nothing was in the way, and if it was desired. Of course, the combined
line could then only use tube-size trains, so that would be one more
reason not to do it.
