How will that improve reliability with the present service?


Not at all, if single track doesn't cause reliability problems.

I am not actually proposing doubling, I am rejecting the "reliability"
excuse for cutting services.

The point is not that the services on the MHE branch are unreliable in
themselves, it's that having an irregular sequence of trains coming
from the northeast reduces reliability at Camden Town, messes about
with train frequencies through central London, exacerbates problems on
the line and leads to greater system-wide delays.
