Yes, the extra demand that will be stimulated by the extension will
funnel more passengers into the already crowded central sections of the
line. As the trains won't be longer, more will need to run, hence the
need for extra paths (and trains). A complete split at Camden Town would
help even more, but that's not practical without a hugely expensive
redevelopment of the station.

IMHO The Waterloo and City may be a better candidate for extension to
Battersea, and perhaps on to Wimbledon.

Maybe operationally, but physically it comes to the surface at
Waterloo facing southeast. The Northern Line idea probably came out
of the fact that it would be relatively straightforward to branch off
from the Kennington loop.

Having seen some details from the promoters at a transport conference last
year I appreciate that is exactly the reason for preferring the Northern
Line, as well as the ability to fit within line capacity by diverting the
West End service there.

Diverting implies that its being diverted from somewhere else. But it
isn't. Kennington is the terminus.

If you look at a map of S london, you'll realise the Northern Line has
to head south east, not south west.

The recent bakerloo extension survey (as well as the original plans)
has it headed East SouthEast, to New Cross and Lewisham. The Victoria
line is headed SE from brixton, and extension plans have it heading to
Herne Hill as a minimum.

That leaves a huge area - around camberwell - utterly without any rail
connection, and certainly without one that's useful for getting into
town.

The only way to plug the gap is for the northern line to go to
camberwell. Which means extending the west end branch that way.

Taking the northern line to battersea really messes that possibility
up, and essentially precludes it ever occurring.

camberwell.

The fact that Camberwell contains a road called "Camberwell Station Road"
shows the flaw in that argument.

up, and essentially precludes it ever occurring.

No - sending half the trains to Battersea and half to Camberwell probably
matches supply with demand better than a single extension.

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.
