Then the examiners, rather than the students, should have been failed.
What did they think the situation was at Binalong, for instance, in the
days when it was covered with lower quadrants?

Except of course they're not "real" accepts.

The knucklehead who placed any of these accepting plates should be
identified and dealt with.

I think that the situation at Demondrille is a relic of when there were
separate north and south boxes. When Demondrille South was cut out, as
it usually was at least in later years, Demondrille [North] box
controlled a considerable distance to the south, so that effectively
there were two Standard Block sections Wallendbeen or Nubba -
Demondrille (south) and Demondrille (north) - Murrumburrah or Harden
South, separated by a region of power signalling controlled from
Demondrille.

When Demondrille South was abolished, the signalling was somewhat
"rationalised", but not much, because Demondrille was still permanently
attended. Then in the next stage when Demondrille could be cut out to
make the long section Harden South - Wallendbeen, the Demondrille area
signalling remained hybrid.
