There is currently no physical connection having served South Hampstead

Queen's Park after Primrose Hill, they'd have to cross immediately to
the AC lines and bypass the stations.

As has been mentioned elsewhere, reopening Primrose Hill as an
interchange with Chalk Farm would at least allow people to change to
the Northern, but basically Kilburn High Road and South Hampstead are
being abandoned. I think there will be a lot of complaints. Being
able to travel to Camden Road is not really equivalent to getting to
Euston in a couple of minutes if you work in central London.

A cheaper option, as I've suggested before, would be to build a new
crossover between Kilburn High Road and Queen's Park and allow
semi-fast trains to run from Euston to serve those two stations, then
cross tracks and stop at the currently unused Queen's Park platorms,
then Harrow and Watford or whatever. They'd have to be dual voltage,
but that's no problem really.

At South Hampstead, IIRC, there are platforms on the 'slow AC' i.e.
Silverlink Country tracks. A Watford, Harrow, Wembly service could in
theory call there. Although I suspect the stairs may need
replacing/refurbishing. I have no familiarity with Kilburn High rd.

The DC line platforms at Kilburn High Road are the original Main Slow
line platforms and what were the Main Fast lines (now the Main Slow)
also had platforms, vestiges of which could still be seen a few years
ago. When the DC line was built Kilburn High Road station was
basically unaltered, the DC lines replaced the Slow lines which were
slewed over to replace the Fast lines which were in turn slewed over
into a new excavation of the southern embankment. Unless somebody has
plonked any new construction into the station area in the past few
years this process should still be reversible to some extent. Bearing
in mind that tighter clearances are permitted with OHLE nowadays,
Primrose Hill DC line tunnels might not be incapable of being provided
with 25kV.
