What ever happened to the proposal too run a branch from the central
line to Richmond and discontinue the district service? Was it all
connected to Crossrail going ahead?

Long gone. The proposal was coupled with a Bakerloo branch from
Willesden Junction to North Acton to take over the Ealing Broadway
branch of the Central line. That rather odd package was an alternative
option studied alongside Crossrail some 20 years or so ago as part of a
general cross-London rail study. It would have been very expensive for
the relatively small achievement of increasing District frequency
between Turnham Green and Ealing.

It would have increased frequency on all branches of the District, and
on the Circle too.
