But at Waterloo, there's a large expanse of open ground in front of
it, so there's ample room to turn south. And there are conveniently
long southward roads adjacent to the railway, suitable for cut and
cover, that connect that open ground to vauxhall.

Mind you, the new development around Battersea has lots of housing,
doesn't it? Extending the Drain would connect that to the City, but
the Northern Line extension would connect it to the West End, with a
cross platform change at Kennington for the City. Northern Line might
be better there?

Northern Line trains are also longer and more frequent, and of course
it's a seven days a week railway. There wouldn't be much point running
the Drain's line to Bank on Sundays.
