I'll be as clear as I can. I don't know anything about London but a
friend of mine that lives there said "Nine Elms" had now changed it's
name to "New Covent Garden",

I think that may be an estate-agent term. Officially the area is still
known as Nine Elms.

I would like to know what is the history and subsequent progress of
the planning of this new line.

There's a lot of information at http://northernlineextension.com

I know the Kennington loop only connects with the west end side of the
northern line because back in the 60s and 70s I worked on it, will it
stay in service?

Almost certainly, as the proposed terminus of the extension at Battersea
is only two-track, which would not be sufficient for turning back the
full peak-time service of the CX branch. I don't think any service
pattern has yet been proposed, but I guess that it might well involve
alternates trains turning at Kennington and Battersea.

The four proposed routes (of which number 2 is the preferred option) can
be seen in:

You will see that they all involve the extension turning off one side of
the existing Kennington loop and returning to the opposite side of the
loop.

Why not? Surely more trains are turned in the two-track terminus at Brixton.

I may have been unduly pessimistic. I've just seen that the Parsons
Brinckerhoff feasibility study into the Northern Line extension
estimates that the Battersea terminus could be capable of turning a
maximum of 28 trains per hour, which I think is the current peak service
on the CX branch (and on the Vic).

However, I doubt that the Kennington loop would be abandoned, as there
won't be the passenger demand for the full service to run to Battersea.
Most people will still want to change at Kennington in order to continue
south towards Clapham and beyond.

You need to include the last letter of the link, which was line-wrapped.
Here it is again, hopefully unwrapped this time:

If you enclose any link which may wrap in and , then good news/mail-
reading agents, not only such as yours but also inferior ones, will
recognise the wrapped URL as a unit.

Did you miss that the last "f" was wrapped onto the next line?
