everyone in the country, not just a few toffs in Chelsea, can bask in
its alleged benefit.

The biggest set of beneficiaries are the 100 million passengers a year

Waterloo who will either get alternatives or much needed extra capacity.

though it doesn't need to leave the mainline at Wimbledon and take a
round the houses route to Chelsea via Balham to achieve that

building the tunnel portal somewhere between Earlsfield and CJ would be
sufficient

CR2 plans to increase trains between Wimbledon and London, and will
allow trains from Chessington and Epsom to get to London without sharing
tracks with the lines from Surbiton. Starting the tunnel north of
Wimbledon wouldn't allow any extra service to Waterloo... the trains
from Wimbledon and the trains from Putney don't share tracks through
Clapham Junction, because both routes have dedicated tracks to Waterloo.

as the bottleneck on the mainline runs all the way back to new Malden, where
are the extra paths on that part going to come from to achieve that?

no, but it would reduce the congestion at the throat as there would be less
(can I use that word as Roland isn't watching me) trains there each morning

It's few years since I travelled the mainline into Waterloo but recall
having to wait there frequently in the past

through Clapham Junction, because both routes have dedicated tracks to
Waterloo.

yes, everybody already knows that :-(

I think the plan was to add a 5th track from the tunnel portal to at
least New Malden... Perhaps Hampton Court Junction.
