More deviously, what about running just Bank-Vauxhall(direct) and
Bank-Waterloo only? Would there be sufficient capacity to
turn more trains at Bank?


There are problems with this, to put it mildly. Firstly, the Waterloo
and City didn't have any other tube lines to connect with when it was
built, because it connected the LSWR with the City, for which reason
it comes pretty much to the surface at both ends and would have to
tunnel down again through significant obstructions.


What sort of depth are the Waterloo platforms at, wrt the outside ground
level - presumably they are only just underneath the station undercroft, at
approximately cut and cover level compared to the outside streets?
