I'm sure in the past when ever there has been a problem (signals, points
failures etc) they tend to use the Charing X Branch for High Barnet to
Morden and trains to/from Edgware travel via the Bank branch.

Or the other way round. The way the junctions are laid out, it makes no
difference.

Just makes life a lot easier for the operator to control a better service
until they can provide a full time table service.

Right.
